Truly informative for all Yamaha A/V amp owners. My vintage (1998) DSP - A1 has a switch on the back for 4 or 8 Ohm. It has always stayed on the 8 ohm position for 22 years. 👍
I just subscribed because what you say just make sense. I'm in the electrical/electronic industry and unfortunately many peoples around just ignore the fundamentals and go on preaching their inaccurate doctrines. Always check the facts! Thanks Gene for just doing that.
Doing a somewhat budget 5.2.2 setup when basement is finished remodeling. Just ordered a2a and 2 sb1000. I'm setting mine up however Gene tells me to. Haha. But seriously, whatever I've learned from this channel in the last 2 months is what in doing. That's why I ordered 2 subs.
I own the A6A. mine does not have a physical switch on the unit. but it does have it on the on-screen menu. However, Yamaha removed the 4ohm option via a firmware update and gave two options. 8 ohm and 6 ohm. I hope to see a new review of this awesome receiver. Thank you, Gene.
Better late than never.... Thankyou for your Power setting post for the Yammy A6A .. I just replaced my Denon X6500h with this new Yamaha receiver.. After several Reviews , a lot of complaints and praise, I took the plunge. Your other reviews that you posted with what this receiver puts out , and your honorable mention , told me this receiver is what I'm looking for . With other High end receivers/processors that are coming out without amplification without any Amps for twice the cost , kinda scares me on what the future cost of a home entertainment center will cost after buying enough Amps to fill your processor...... And the RX-A6A is the best chose for having the same power as the A8A and included BALANCED PORTS to Amp my front 4 Ohm speakers . This should carry me through for many years ....
Hi. I have recently installed the Yamaha rx a6a receiver in a theater where there was a faulty marantz 9.2 receiver was installed before this Yamaha. Now, following your instructions as you have a lot of experience in this field. The speakers have changed there properties a bit. Some 4ohm speakers now have 3.5 or 3.6/7 ohms and ceiling speakers originally 6ohms are no now showing 6.5/7 ohms. Again I want to ask that should I choose the best matching impedance setting which is 4ohm minimum which means that fronts have 4ohm and others have 6/8 ohms. As we know that impedance matching is important for interfacing any two circuits. Lower impedence can cause overdriving of the amp and higher impedence will decrease the output power of the amp. Now this is a general concept. How can we say that a manufacturer not only Yamaha but almost all of them have created this feature/switch so user can select the impedence according to the speaker impedence is a useless feature. Yes you are right, if it will decrease the output power on lower settings, if not set properly can it effect the amplifier or the speakers by making the speakers more power hungry or forcing the amplifier to deliver more power? Your expert opinion is required.
Great video. A true advice and comment with real measures. I have a A6A and I am learning a lot. Thank you, I want more ... The others youtubers coments about A6A is just bla....bla. I never give any credibility to coment that isnt based on real measures. Gene you are on the rock.
Thank you. I have had the A6A and before that had the 2040. I am not rich, but have a 15' x 30' theater/rec room setup in the basement. I have an Atmos 7.1.2 setup with an SVS 18" powered subwoofer. All of my speakers are Klipsch. I have been so happy with the performance, but I am now wondering if I should add some sort of external amplifier to help out the A6A. I watch movies with the volume between -24 and -18 volume on the A6A.
You don't need an external amp based on your listening habits and high efficient speakers you own. Put your budget into some room acoustics treatments and/or some professional consultation service.
Gene, great video and data points with regard to impedance selection and extra bass settings. Replacing my 27 year old RX-V690 Dolby Surround 5.1 (85 W/channel 2 channels driven) with the RX-A2A at 100 watts is a "beast" as you say. Dolby ATMOS sound is mind-blowing with volume levels set at -20 dB to -15 dB.

Thanks for that. Are there any negatives to this? Can the avr or the 4 ohm speakers get damaged with the high setting? Also I am in a peculiar situation in which I upgraded my speakers but because of supply chain issues I only got the center channel which is 4 ohms but the rest are 8 ohms. Would this cause any problems while I wait for the rest of the 4 ohm speakers to arrive?
Thanks man. We just picked up an RX-A770 receiver and are figuring out how to set it all up. This seems like it will help us as we stumble thru the process.
50 watts at 7 channels is WILD. 25 is INSANE. Please do a video about all the advantages to adding an amp or amps to a receiver. Matt recently commented in a thread on ASR that people would be surprised how often AV receivers go into clipping. It would be nice for you guys to elaborate on that topic!!!
They have in the past. Av receivers on its own power supply vs separates/ additional amplification. These are older videos and still useful today for anyone.
@@MrJjburgess11 it's a good channel on RUclips. And very educational on audio and equipment specs etc. Been watching audioholics for years. Enjoy the channel brother.
I want a full hour deep dive talk. Maybe a "case study" of a 1500 or 2000 dollar receiver with 4 ohm speakers, 7 channels being driven vs what actually happens when you add a 5 channel amp and run 2 off of the receiver. Is it worth the cost in an average size room at less than reference (lets say 75db) listening level. What actually is happening over the course of a movie (or loud 2 channel) to justify extra amplification? It would be a interesting and educational video that no one has actually broken down with the expertise that audioholics could provide.
Thanks for that! Intending to get an A6A as part of a home theater upgrade as soon as they become available again (guess they're sitting on a ship off LA), replacing my old Onkyo TX-NR3007 (no HDMI 2.1). 7.1.2 system. Just looked up impedance on my old SVS MTS (6Ω), MCS (6Ω), and MBS (8Ω). Had thought lower than that, so good in any case.
You will love the upgrade. I did a surround system with 5 Martin Logan Sistine speakers (4ohms) and a Yam 3080. The amp handles the load and has more than enough power. Anthem is the upgrade when you need more power than what Yam, Denon, Sony, etc.. have.
P.S. This is the morning of my third day of owning my A6A and the firmware update was waiting on me this morning . I went from FW update 1.59 to FW update 1.80 ... My system is running well with very few issues that all Have been resolved... This is a much better receiver than how it reviewed a year ago . And the remote plays well with my Sony TV... and runs several function for my tv , Samsung UHD blueray player , and turns off my cable box..... I use my cable tv remote for everyday use , and hit the power button on my cable tv to turn on my tv, cable box, and my receiver , A well as turning everything off.... all this without programing and right out of the box....
So what's the purpose of putting 4,6 ohms on a receiver if its not practical to use? Would is be better to use a separate amp like the Emotiva XPA-7 Gen3 7 Channel Power output: 200 watts/channel RMS into 8 Ohms; all channels driven , 300 watts/channel RMS into 8 Ohms; two channels driven , 490 watts/channel RMS into 4 Ohms; two channels driven? I have until Nov 12 to return the A6A to BestBuy. I just wanna make sure its worth the money. Man , if Best Buy would've had the Onkyo TX RZ50 in I would've have that first and save my self a thousand dollar. Thanks Gene for what you're doing I really appreciated..
2 years ago I bought the Aventage A2A, and unfortunately, I've been very disappointed with the anemic power. I've been happy with my old Yamaha RX-V490 with a lesser power rating, and expected a slight improvement in power with the A2A. Instead, it was MUCH less power and I am now struggling with the idea of spending even more money on an external amp. Heck, I'm even thinking of powering the A2A with my old receiver until I decide. I tried both the 8 and 6 ohm settings - same problem. Especially with the 4 ohm speakers I had but even with the old JBL's rated at 8 ohms. The old receiver sounded better and had more power. I was hoping this video would tell me I was doing something wrong, so I could correct it, but no go. Obviously I'm not an audiophile, but this was step 1 in what I wanted to be an upgrade to my whole system, but now I find myself limited to highly efficient 8 ohm speakers - and I just don't want to settle. I also don't want to spend a ton more money on power (like more than $700.00 or so) - so yeah. Really disappointed in the A2A. (speakers were Bose 8.2, and/or JBL CF-120's). I will be replacing them but wanted to solve my power problem first.
Ya had me a bit confused for a minute, you were saying one thing and the charts clearly said something different, and then a minute later it all came into alignment for me. Onkyo is my brand of choice and they use some kind of dynamic amp setup, I personally think it's mostly marketing. But you do have me curious about this as I have my receiver set to 6 ohms since all my mains are rated as such. I seriously doubt I'll notice any difference by switching to 8, but I'm willing to give it a try. But I agree 100% this really shouldn't even be an option at all since every amp on the market is load dependent already! In other words, the amp won't do anything until it sees a load. It shouldn't make a difference what you set the amp to since the speaker impedance is constantly changing while in use. I only changed my receiver to 6 ohms because of the dynamic amp marketing jargon, it could make a difference in my case if it actually does what it says on the tin. But I don't honestly know. Do you have any charts for Onkyo?
They all function pretty much the same. You're doing your speakers a disservice by setting the switch to 6 ohms. I can't restate this enough before it sinks in for some people.
@@Audioholics: There's nothin wrong with a bit of skepticism, in fact it helps to keep the mind sharp. Although, skepticism becomes something else once proof is shown and folks still don't believe. I'm a numbers man, it's all just hot air until somebody can show me those numbers! Audio reproduction was developed with science, as it will continue with science.... Everything else is just noise. Cheers 🍻.
@@Audioholics: Just rechecked my receiver and the only option I have is 4 ohm or 6 and above. So yeah, nothing to adjust then since I've always been set to 6 and above.
Now the question is, if i have 2, 7 channel amplifiers 200w ch, all 7 driven @8ohms, 300w all channels at 4 ohms. Do i use 4 or 8 ohms on the receiver in pre-amp mode? Still cant find answer to that. I have 7.2.6 atmos setup. Speakers are, front Dali Rubicon 8 4 ohms, center is 4ohms Rubicon Vokal, surrounds R L are Rubicon LCR 4ohms. Rest are 6 ohms Oberons. What do i do with setting in this case? I have DENON 6700 receiver, that allows selection of 8, 6 and 4ohms. I know it's not Yamaha, but pretty much same questions with this settings. Same Japanese Ohm settings. As far as i read, it's still best set to 8 ohms, as with 6 and 4 i am just going to lose dynamics.
Thanks for this video. I was about to pull the trigger on an A6A… until I learned its 7 channel power. 52w is not acceptable and it’s unfortunate that Yamaha purposely cut power that drastically and there is nothing a user can do about it. My current Onkyo is bench tested at 103wx7, I’m very happy with its audio quality, so I’ll hang onto that for a few more years.
Question I want to get your advice. In my loft I have the Yamaha V6A. My front speakers are custom built running at 2 OHMS. All of my speakers are very very efficient. I never push it hard cuz I just use this for watching TV, Sports and sometimes Pandora for listening to music. Do I still keep it at the high 8 ohms?
Looking to buy new receiver, thinking the A6A. Snell 5.1 speaker system right now, height speakers down the road. My question, was going to bi amp my main towers with the extra channel. After watching this would using the extra channel add more nanny's and actually cutting the power to my system ? Or should I still bi amp? I both listen to music and movies. Loud music, rock n roll.
Hi , I have a RX-V6A Yamaha Receiver ! On my Front Right & Front Left Speakers it will Sound good for a while & then I lose my Vocals on my left side but not on my right side ! I still get the background noise but not the vocals on just my left side ! Is there any way you could help me understand what’s going on ? If I move the speaker to the right side it works fine , so I know it’s not my speaker ! HELP PLEASE ! Thanks
Hi Gene. Thank for your video! Could you answer me 100W on 8Ohm = same as 100W on 6Ohm ? Because when I switch to 6Ohm Receiver require more power from 220V. Why ?
I have a Golden Ear XL PASSIVE soundbar with two Super Sub x and a pair of the super sat 3’s for a 5.2 system and I have a 21-12 room with a 8’ ceiling and I am going to use the other two channels outside I am looking at the Yamaha A4A or a Dennon 2800 I like moves and music but I am really into sound quality for music out of the two AVR Receivers what is the best choice
Thanks for the informative video....what are your thoughts...Im considering the Yamaha RX-A1080 vs the A6A to power 5 monitor audio speakers in a 18x 24 room with glass sliders...Thanks
Hello hope your doing well I have the yamaha rx-a3080 I recently added a emotiva basx 3 channel amp the receiver doesn't let me select an external amp for now I'm only running 5.1 setup with klipsch speakers any help would be appreciated thanks
Have yamaha got back to you Gene? Have got an a8 and have 7 days left to return, and am a bit nervous about how much of an improvement these are. Although saying that I don't fancy any of the other bug ridden competitors at the moment.
I'm also waiting on that review, I'm starting to get cold feet to the point where I'll cancel my A6A per-order and grab a cheapie until next years models drop.
@@UltimateGattai well everything is working apart from the ypao which seems to take away all the bass. But apart from that I'm happy, it has opened up my cheaper speakers a bit better but won't be able to tell properly till I buy my new ones. Just wish he'd update on yamaha's response. If there is one.
@@slyfoxx8540 that's good to hear, I really wanted this AVR to be good since I've only owned cheap, budget AVRs before, plus I want to add in 11 channels. I'm planning to get atmos speakers at the same time and install next year along with either a 2 or 3 channel power amp.
@@slyfoxx8540 I found the same thing on my older 3060, YPAO takes away the bass. Although the "Natural" setting is the least offensive I ultimately started using the "Manual" setting and keeping all speakers flat (No EQ) and bumping up the mid bass frequencies of the subwoofer just a bit. I haven't taken any measurements but it sounds better to me.
Great video just wondering does this knowledge also applies for entry level receivers like the Yamaha tsr 700 paired with 6 ohm speakers ns f350 and ns p350, should be set to 8 ohm?
Too funny...I read your comment and thought...I also have the tsr 700 paired with 6ohm speakers..I'd like to know the answer too..then I saw your name! 😆
Quick question, Yamaha A4A I’m amplifying the LCR channels. The rest of my speakers are 6 OHMS, do I keep it at 8 or 6 OHMs. I guest leave it at 8 ohms. Thanks.
Hello I am confused a need recommendations. I ordered the Yamaha Aventage A6@. I currently have a 5.0 system. I wanted to upgradw to a 5.0.4 atmos. I would like to get a preamp for my front L/R speakers. I have oñder Cerwin Vega VS series 15”, there RMS is 500 watt each. What type, brand or wattage do I look for. Econ price please. Also atmos speakers (mounted on-wall not in-wall) can you help me please.
Interesting. I'd like to try one of these with a separate power amp. There's a second hand Luxman M-700 that I have my eye on. Shame the colours won't match.
I appreciate and enjoyed the video. Keep up the great work. I’m waiting for your final review on the rx A6A, to decide in buy it or the denon 4700H. I will use it mainly for movie watching surround sound and gaming on next gen ps5 and pc RTX 3080, so I kinda need more than one hdmi 2.1 port.
I always wondered about this. I have 6 ohm Dali speakers and a Yamaha A3060 and i thought you were meant to set Ohms on Amp to match speakers precisely otherwise you could damage the speakers. In doing so it does affect volume considerably.
Bought the A6A about a week ago and just today started working on settings and sound levels…. With the TestTone going through the speakers no issue until it came to the subwoofer 1 and 2. I have a pair of REL G1’s connected to the sub outputs and no sound during test tone and put on a DVD with big bass and again nothing. Subs work fine with my Hegel 390 as well as my Devialet Expert 220 pro using the high level output and the rca output on the Devialet. Any thoughts that this is an issue with others?
My Onkyo receiver has the same switch in its speaker setup menu. I assume that any receiver that has this switch should be able to adequately driver 4 ohm speakers, correct? Otherwise, there seems to be no reason to even include the switch if the receiver isn't capable. It's an Onkyo TX-NR727. Thanks!
THX again Gene.... The empirical proof is in the pudding... ALWAYS. My machine is RXA2080 but I suspect there to be a lot of parallels here given Yamaha's designs, parts. I didn't put much stock in Eco this and extra loudness that because you run your signal through even more chips and parts correct? K.I.S.S. Keep it simple... God Bless and long life ole friend.
Gene, how does the A6A respond when the balanced outs are utilized for the front mains? Does that give more oomph back for the remaining channels? Could you test that for us? This is the operational mode I was planning on using this product for.
Yamaha a2a, is it worth using the bi-amp? Would that technically be using more than 2 channels? Seems like there would more than likely be a power loss when running my my front L&R only.
Thank you for the informative video regarding IMPEDANCE Switch..Question...I have the Yamaha TSR 700 receiver...I cannot locate this switch..it isn't mentioned in the manual, so, where can I find this switch, and how do I change it. Thanks!
English is not my native language and I don't know if I understood it correctly. I have the yamaha a6a with an old jamo 606 set that is 6ohm, so I lowered it to 6ohm on the avr since I read that it could be harmful if I didn't. So, even if the speakers are 6ohm, do I have to set the arv to 8ohm? Will it not harm the avr or the speakers?, thanks!
3070 set at 8ohm with 8ohm speakers, only way go. Gene I'm using two external amps, so my 3070 is only powering fronts and centre, what roughly would be the power going to these please???
so........will it be ok to hook up 4 ohm speakers to these receivers? I know you said to keep it in 8 ohm settings but just wondering if that's the same for 6 ohm as opposed to 4 ohm or lower?
For the most part yes provided you have good ventilation. If the AVR Shuts down at high listening level, add external amplification on the front 3 channels to lighten the load.
@@Audioholics gotcha, will do. I don't have power amps but I have old receivers hooked up to my pre amp outputs. I have an old denon and an onkyo. trying to get the settings adjusted for those 2 however. I'm not sure if the eq settings in the yamaha affect the output of the 2 receivers I have hooked to it. for instance, when I plug it (my denon) into surround it has no highs (I set my yamaha to have only bass coming out the surround 2 speakers at they are just subs and don't have any mids or tweeters hooked to it). whereas when I plug for instance, the denon into the yamaha's "surround back" and the eq is untouched on that channel then it sounds fine coming out the denon. I'm just wondering if i'm wrong about how the eq works when plugging external amps into the various pre amp output channels or if messing with the eq for the channels that is being used by an amp/receiver will change how they output sound too? or am I plugging the receiver into the wrong pre-amp outputs? Hope I'm making sense here. I might make a video explaining what I mean if typing doesn't make sense.
Gene, what is happening with the A6A? No updates for so long now. Are we still getting a full review from you? I’m waiting for your expertise and honestly before making a purchase on this product!!!
I have my receiver set at 8 ohms with all the extras off other than Dsp but I often run in pure direct mode for music and movies. I like how pure direct sounds better than straight mode but I sometimes wonder if I just stick to straight mode since I’m using bookshelf speakers and a sub.
Hi, interesting theory too everyone's take on this topic. I have had quite a few Yamaha over the years and I like the older ones better I have a Yamaha Aventage rx-a2050 and before I had an rx-a1010 I did just the bias to 16.7 it was originally set to 15.2 the services manual does say 15 plus or minus 2% I find it gets a bit hotter with it at 16.7 but sounds warmer to me on the Yamaha rx a2050 I set my bias on all channels to the 16.4 on this receiver and I installed about double the capacitor this unit runs at about 59 too 60 volts plus and minus the unit comes with only 2 * 12,000uf 71 volts capacitor for all 9 channels it seems as the power supply was sagging so I add about a extra 10,000 of 80volt to each rail and it proves they skip out on capacitors for power supply i also changed out the bridge rectifier too a 30 amp instead of the 15 A that was installed on this unit after that i have no complaints about this unit i also add a fan as it does run hotter now but sounds great and drives all my channels with a punch and clarity thats my take on this receiver the new receiver rx-a6a and up use the same amplifier modules just different capacitors but same transistors and layout. I bought mine used it also has two supply rails hookup to a relay at 64 and 37 volts this will switch to 37 volts in the 6 ohm or eco mode or handy cap mode lol if you have small speakers as satellites and are 4 ohm or 6 ohm it will sound better due to the power cut off too 37 volts
Use the corresponding tap to what your speakers are. Remember impedance is "nominal" and changes constantly with the music. Heavy bass tracks will be your low impedance stressors, classical music with violin solos are at the other end of the impedance load. Just be sure your amp can handle the load of the speakers, and also be aware when something seems too good to be true for the money...
I have a denon X4400h that I run in eco mode with all 11ch being powered by external amps. The only thing that has been affected is the temperature of the unit, with it running about 5 degrees cooler then when I had eco mode off.
Honestly, I tried AV recivers, and get tired of them doing funky busines with sound mixing, crosovers, and what not that is not exatly documented enywhere. Now just running signals in seperate components , pro speaker management dsp and power amp. Plenty of versatility and power. For a home gamer type AV reciver is way to go, less hashle, and almost plug and play. With pro gear you need to know what you are doing. I personally prefer pro gear.
Gene, I'll bet a dollar that the guys who tell you the lower impedance setting sounds better with 4 ohm speakers are the same guys who say their expensive aftermarket power cords sound better too...
@stephen sheldon i agree.didnt say they had to be expensive.all of mine are custom made with materials totalling around £ 50 - £ 100. sound good enough..
Tell you guys what. Why don't you go to the Audioholics forums and start a thread talking about the awesomeness of aftermarket power cords? It should spark an interesting discussion... Lol
While you're at it, why don't you take a look at the many, many articles gene has written on the subject where he breaks down how silly this idea is from the viewpoint of an electrical engineer...
@@Pohgrey i already have done. ive got to admit they do. but if you want to think the other way ,thats your choice. ive been listening to gene for many years and i do agree with him. but i also agree with all others like paul from ps audio. and many many others. if it wasnt the case that the sound changes from cable to cable,then every one would just use cheap wire. but thats not the case. and im sure youve spent as much money as you feel is right for your system too. right? its just the way this cables debate goes. ive come to a conclusion that both parties are correct.
Thanks for the info. Interesting. I guess my first instinct was that the impedance switch is there to protect the speakers as much as the receiver. Is keeping it at 8 rather than 4 Ohm going to have any affect in the speakers at high volumes? Cheers.
Sounds like I should be good with power. I just brought the 1723s THXs to go with this. Moving on from my Aperion Grand Versus 1s. Wife doesn't know yet? Cross that bridge when I get there.
Thanks a lot for the video, very interesting .can you tell me if the rule of leaving the impedance set at 8ohm also applies to the Yamaha R-N803 on a two channel system driving two Elac dbr62? thanks again
What's your assessment in 2021 of quality/value of pairing Yamaha with a pair of REVEL F36 towers? (80% movies / 20% music) .. SVS PB2K subs || Note, the question is.. F36's vs. possibly getting SVS Ultra's instead.
My receiver doesn't even have impedance switch, but my highs are much more detailed and airy, mids are chocolatier and bass is much tighter when I switch it to 4 ohms.
I had the same thoughts about the ultra center as left and right speakers, it's almost like having the ultra towers without taking up all that space especially if you also have a sub. Let me know if this is what you have.
@@ulissepellegrino7175 yeah so true, thanks for the reply. I ended up buying the ultra book shelves and man they cranked up nicely I love them. Bloody expensive tho. $1700 Australian for a pair but I say pay once cry once lol 😂. I will eventually get the svs ultra center only to just keep things timber matched.
Hi there guys Ives been a fan since you first got covid lol. I have a question that's a bit off topic. I bought a new theater system and I followed your subwoofer setup videos. I have an R 100sw klipsh sub and my av reviewer is the Onkyo TX-NR595. I set the crossover on the reciver to 80hz and the level on the sub to 50%. When I run the automatic setup it sets the sub to +3db. Problem is, when I play any movie it just rumbles the whole time unless I turn the level down to about 25%. Any help from the community would be appreciated.
Is it truly bass rumble? Or vibrations? Make sure the sub is isolated from anything it can vibrate. You may then find that you just hear low movie bass as you should. The speaker tests are a quick punch - not a sustained bass track like a movie. I isolate front firing subs on a thick rubber paver on top of a 2' x 2' concrete paving stone (Home Depot landscaping area). For floor firing I isolate on the same but on top of the rubber pad I add a 2' x 2' x 1" thick square block of hard wood. Looks like a weird smore but prevents the sub from vibrating the floor or anything around it.
Thanks for a very useful video trying to help audio enthusiasts like me extract best performance out of the sound investment we have made. Have a question on this. What happens if I have pre-amp outed the front speakers on to a two channel Yamaha power amp MX 600, from a Denon X3600H receiver. MX 600 also has a Impedance switch at the back which I have left as 8 ohms as per your advice. Your graph on 2 channel driven performance doesn’t seem to have much of an issue. Thanks once again hoping to receive a reply. Regards
Now some guy with his 9 Channel JBL speakers playing reference level sine waves while at work to break in his new speakers and wondering how his house burned down. I kid but I wish you would have at least given a brief explanation of why this setting exists. I know you've hit on it in your previous videos, but I'm sure you made some poor electrical engineer at Yamaha cringe saying you would never under ANY circumstance use anything lower than the highest impedance setting. Love the video though, always appreciate the graphs.
Back before I knew better . I was using the 6ohm setting on my Yamaha a2080. My q acoustics are are 6 ohms. But after watching one of your videos from a while back. I put it back on 8 . But I have moved onto separates now. With a monolith 9x.
yamaha rx-a2a aventage is only 24ibs that's not a good thing in my opinion. If it has seven channels and comes in under 30 lb that makes me shy away from it.
I switch to 6 ohms and definatley noticed it was limiting current, switched back to default 8 and left it there, sounds better and louder with less distortion , yamaha system too.
Truly informative for all Yamaha A/V amp owners. My vintage (1998) DSP - A1 has a switch on the back for 4 or 8 Ohm. It has always stayed on the 8 ohm position for 22 years. 👍

Thank you for the information Gene!! Great stuff as always!! Love your work… BOOM
please make video on parametric eq and what settings are best
I'd assume that the EQ would be best configured depending on the speakers you have connected to it.
Better late than never.... Thankyou for your Power setting post for the Yammy A6A .. I just replaced my Denon X6500h with this new Yamaha receiver.. After several Reviews , a lot of complaints and praise, I took the plunge. Your other reviews that you posted with what this receiver puts out , and your honorable mention , told me this receiver is what I'm looking for . With other High end receivers/processors that are coming out without amplification without any Amps for twice the cost , kinda scares me on what the future cost of a home entertainment center will cost after buying enough Amps to fill your processor...... And the RX-A6A is the best chose for having the same power as the A8A and included BALANCED PORTS to Amp my front 4 Ohm speakers . This should carry me through for many years ....
Hi. I have recently installed the Yamaha rx a6a receiver in a theater where there was a faulty marantz 9.2 receiver was installed before this Yamaha.
Now, following your instructions as you have a lot of experience in this field. The speakers have changed there properties a bit. Some 4ohm speakers now have 3.5 or 3.6/7 ohms and ceiling speakers originally 6ohms are no now showing 6.5/7 ohms.
Again I want to ask that should I choose the best matching impedance setting which is 4ohm minimum which means that fronts have 4ohm and others have 6/8 ohms. As we know that impedance matching is important for interfacing any two circuits. Lower impedence can cause overdriving of the amp and higher impedence will decrease the output power of the amp. Now this is a general concept.
How can we say that a manufacturer not only Yamaha but almost all of them have created this feature/switch so user can select the impedence according to the speaker impedence is a useless feature. Yes you are right, if it will decrease the output power on lower settings, if not set properly can it effect the amplifier or the speakers by making the speakers more power hungry or forcing the amplifier to deliver more power? Your expert opinion is required.
Great video. A true advice and comment with real measures. I have a A6A and I am learning a lot. Thank you, I want more ... The others youtubers coments about A6A is just bla....bla. I never give any credibility to coment that isnt based on real measures. Gene you are on the rock.
Thank you. I have had the A6A and before that had the 2040. I am not rich, but have a 15' x 30' theater/rec room setup in the basement. I have an Atmos 7.1.2 setup with an SVS 18" powered subwoofer. All of my speakers are Klipsch. I have been so happy with the performance, but I am now wondering if I should add some sort of external amplifier to help out the A6A. I watch movies with the volume between -24 and -18 volume on the A6A.
You don't need an external amp based on your listening habits and high efficient speakers you own. Put your budget into some room acoustics treatments and/or some professional consultation service.
Gene, great video and data points with regard to impedance selection and extra bass settings. Replacing my 27 year old RX-V690 Dolby Surround 5.1 (85 W/channel 2 channels driven) with the RX-A2A at 100 watts is a "beast" as you say. Dolby ATMOS sound is mind-blowing with volume levels set at -20 dB to -15 dB.
My RX-A4A came in yesterday and I am beyond impressed with the sound quality this thing produces.
I’m jealous!! When did you pre order it?
@@southpawle641 I didn’t to be honest. I bought it Thursday night from Best Buy online and it came two days later.

@@ACSforEpic nice! And the receiver’s amp runs all your speakers well?
Thanks for that. Are there any negatives to this? Can the avr or the 4 ohm speakers get damaged with the high setting? Also I am in a peculiar situation in which I upgraded my speakers but because of supply chain issues I only got the center channel which is 4 ohms but the rest are 8 ohms. Would this cause any problems while I wait for the rest of the 4 ohm speakers to arrive?
great question.
Thanks man. We just picked up an RX-A770 receiver and are figuring out how to set it all up. This seems like it will help us as we stumble thru the process.
50 watts at 7 channels is WILD. 25 is INSANE. Please do a video about all the advantages to adding an amp or amps to a receiver. Matt recently commented in a thread on ASR that people would be surprised how often AV receivers go into clipping. It would be nice for you guys to elaborate on that topic!!!
They have in the past. Av receivers on its own power supply vs separates/ additional amplification. These are older videos and still useful today for anyone.
@@EJHilt 100% . I learned so much in the past year from watching all these videos.
@@MrJjburgess11 it's a good channel on RUclips. And very educational on audio and equipment specs etc. Been watching audioholics for years. Enjoy the channel brother.
I want a full hour deep dive talk. Maybe a "case study" of a 1500 or 2000 dollar receiver with 4 ohm speakers, 7 channels being driven vs what actually happens when you add a 5 channel amp and run 2 off of the receiver. Is it worth the cost in an average size room at less than reference (lets say 75db) listening level. What actually is happening over the course of a movie (or loud 2 channel) to justify extra amplification? It would be a interesting and educational video that no one has actually broken down with the expertise that audioholics could provide.
Thanks for that! Intending to get an A6A as part of a home theater upgrade as soon as they become available again (guess they're sitting on a ship off LA), replacing my old Onkyo TX-NR3007 (no HDMI 2.1). 7.1.2 system. Just looked up impedance on my old SVS MTS (6Ω), MCS (6Ω), and MBS (8Ω). Had thought lower than that, so good in any case.
You will love the upgrade. I did a surround system with 5 Martin Logan Sistine speakers (4ohms) and a Yam 3080. The amp handles the load and has more than enough power. Anthem is the upgrade when you need more power than what Yam, Denon, Sony, etc.. have.
P.S. This is the morning of my third day of owning my A6A and the firmware update was waiting on me this morning . I went from FW update 1.59 to FW update 1.80 ... My system is running well with very few issues that all Have been resolved... This is a much better receiver than how it reviewed a year ago . And the remote plays well with my Sony TV... and runs several function for my tv , Samsung UHD blueray player , and turns off my cable box..... I use my cable tv remote for everyday use , and hit the power button on my cable tv to turn on my tv, cable box, and my receiver , A well as turning everything off.... all this without programing and right out of the box....
Like always.... Great info.! Thanks Gene. 👍👌👏
So what's the purpose of putting 4,6 ohms on a receiver if its not practical to use? Would is be better to use a separate amp like the Emotiva XPA-7 Gen3 7 Channel Power output:
200 watts/channel RMS into 8 Ohms; all channels driven , 300 watts/channel RMS into 8 Ohms; two channels driven , 490 watts/channel RMS into 4 Ohms; two channels driven?
I have until Nov 12 to return the A6A to BestBuy. I just wanna make sure its worth the money. Man , if Best Buy would've had the Onkyo TX RZ50 in I would've have that first and save my self a thousand dollar. Thanks Gene for what you're doing I really appreciated..
2 years ago I bought the Aventage A2A, and unfortunately, I've been very disappointed with the anemic power. I've been happy with my old Yamaha RX-V490 with a lesser power rating, and expected a slight improvement in power with the A2A. Instead, it was MUCH less power and I am now struggling with the idea of spending even more money on an external amp. Heck, I'm even thinking of powering the A2A with my old receiver until I decide. I tried both the 8 and 6 ohm settings - same problem. Especially with the 4 ohm speakers I had but even with the old JBL's rated at 8 ohms. The old receiver sounded better and had more power. I was hoping this video would tell me I was doing something wrong, so I could correct it, but no go. Obviously I'm not an audiophile, but this was step 1 in what I wanted to be an upgrade to my whole system, but now I find myself limited to highly efficient 8 ohm speakers - and I just don't want to settle. I also don't want to spend a ton more money on power (like more than $700.00 or so) - so yeah. Really disappointed in the A2A. (speakers were Bose 8.2, and/or JBL CF-120's). I will be replacing them but wanted to solve my power problem first.
Ya had me a bit confused for a minute, you were saying one thing and the charts clearly said something different, and then a minute later it all came into alignment for me. Onkyo is my brand of choice and they use some kind of dynamic amp setup, I personally think it's mostly marketing. But you do have me curious about this as I have my receiver set to 6 ohms since all my mains are rated as such. I seriously doubt I'll notice any difference by switching to 8, but I'm willing to give it a try.
But I agree 100% this really shouldn't even be an option at all since every amp on the market is load dependent already! In other words, the amp won't do anything until it sees a load. It shouldn't make a difference what you set the amp to since the speaker impedance is constantly changing while in use. I only changed my receiver to 6 ohms because of the dynamic amp marketing jargon, it could make a difference in my case if it actually does what it says on the tin. But I don't honestly know. Do you have any charts for Onkyo?
They all function pretty much the same. You're doing your speakers a disservice by setting the switch to 6 ohms. I can't restate this enough before it sinks in for some people.
@@Audioholics:
There's nothin wrong with a bit of skepticism, in fact it helps to keep the mind sharp. Although, skepticism becomes something else once proof is shown and folks still don't believe. I'm a numbers man, it's all just hot air until somebody can show me those numbers! Audio reproduction was developed with science, as it will continue with science.... Everything else is just noise.
Cheers 🍻.
@@Audioholics:
Just rechecked my receiver and the only option I have is 4 ohm or 6 and above. So yeah, nothing to adjust then since I've always been set to 6 and above.
Now the question is, if i have 2, 7 channel amplifiers 200w ch, all 7 driven @8ohms, 300w all channels at 4 ohms. Do i use 4 or 8 ohms on the receiver in pre-amp mode? Still cant find answer to that. I have 7.2.6 atmos setup. Speakers are, front Dali Rubicon 8 4 ohms, center is 4ohms Rubicon Vokal, surrounds R L are Rubicon LCR 4ohms. Rest are 6 ohms Oberons. What do i do with setting in this case? I have DENON 6700 receiver, that allows selection of 8, 6 and 4ohms. I know it's not Yamaha, but pretty much same questions with this settings. Same Japanese Ohm settings. As far as i read, it's still best set to 8 ohms, as with 6 and 4 i am just going to lose dynamics.
Thanks for this video.
I was about to pull the trigger on an A6A… until I learned its 7 channel power. 52w is not acceptable and it’s unfortunate that Yamaha purposely cut power that drastically and there is nothing a user can do about it. My current Onkyo is bench tested at 103wx7, I’m very happy with its audio quality, so I’ll hang onto that for a few more years.
Question I want to get your advice. In my loft I have the Yamaha V6A. My front speakers are custom built running at 2 OHMS. All of my speakers are very very efficient. I never push it hard cuz I just use this for watching TV, Sports and sometimes Pandora for listening to music. Do I still keep it at the high 8 ohms?
See: ruclips.net/video/Ou5bO8P2Drw/видео.htmlsi=gc_uUDkQKDQ90Lmi
Looking to buy new receiver, thinking the A6A. Snell 5.1 speaker system right now, height speakers down the road. My question, was going to bi amp my main towers with the extra channel. After watching this would using the extra channel add more nanny's and actually cutting the power to my system ? Or should I still bi amp? I both listen to music and movies. Loud music, rock n roll.
Hi , I have a RX-V6A Yamaha Receiver ! On my Front Right & Front Left Speakers it will Sound good for a while & then I lose my Vocals on my left side but not on my right side !

If I move the speaker to the right side it works fine , so I know it’s not my speaker ! HELP PLEASE ! Thanks
Hi Gene. Thank for your video! Could you answer me 100W on 8Ohm = same as 100W on 6Ohm ? Because when I switch to 6Ohm Receiver require more power from 220V. Why ?
I have a Golden Ear XL PASSIVE soundbar with two Super Sub x and a pair of the super sat 3’s for a 5.2 system and I have a 21-12 room with a 8’ ceiling and I am going to use the other two channels outside I am looking at the Yamaha A4A or a Dennon 2800 I like moves and music but I am really into sound quality for music out of the two AVR Receivers what is the best choice
Thanks as always Gene. Would you recommend upgrading from the Aventage A770?

Have yamaha got back to you Gene?
Have got an a8 and have 7 days left to return, and am a bit nervous about how much of an improvement these are.
Although saying that I don't fancy any of the other bug ridden competitors at the moment.
I'm also waiting on that review, I'm starting to get cold feet to the point where I'll cancel my A6A per-order and grab a cheapie until next years models drop.
@@UltimateGattai well everything is working apart from the ypao which seems to take away all the bass.
But apart from that I'm happy, it has opened up my cheaper speakers a bit better but won't be able to tell properly till I buy my new ones.
Just wish he'd update on yamaha's response.
If there is one.
@@slyfoxx8540 that's good to hear, I really wanted this AVR to be good since I've only owned cheap, budget AVRs before, plus I want to add in 11 channels. I'm planning to get atmos speakers at the same time and install next year along with either a 2 or 3 channel power amp.
@@slyfoxx8540 I found the same thing on my older 3060, YPAO takes away the bass. Although the "Natural" setting is the least offensive I ultimately started using the "Manual" setting and keeping all speakers flat (No EQ) and bumping up the mid bass frequencies of the subwoofer just a bit. I haven't taken any measurements but it sounds better to me.
Great video just wondering does this knowledge also applies for entry level receivers like the Yamaha tsr 700 paired with 6 ohm speakers ns f350 and ns p350, should be set to 8 ohm?
Too funny...I read your comment and thought...I also have the tsr 700 paired with 6ohm speakers..I'd like to know the answer too..then I saw your name! 😆
@@joelgonzalez8289 lol
Quick question, Yamaha A4A I’m amplifying the LCR channels. The rest of my speakers are 6 OHMS, do I keep it at 8 or 6 OHMs. I guest leave it at 8 ohms. Thanks.
according to this video it would be best to leave it at 8 ohms as the receiver will provide the speakers with more power at 8 ohms.
Should I do 7.2.2 on this? what kind of power will it push?
Hello I am confused a need recommendations. I ordered the Yamaha Aventage A6@. I currently have a 5.0 system. I wanted to upgradw to a 5.0.4 atmos. I would like to get a preamp for my front L/R speakers. I have oñder Cerwin Vega VS series 15”, there RMS is 500 watt each. What type, brand or wattage do I look for. Econ price please. Also atmos speakers (mounted on-wall not in-wall) can you help me please.
Interesting. I'd like to try one of these with a separate power amp. There's a second hand Luxman M-700 that I have my eye on. Shame the colours won't match.
I appreciate and enjoyed the video. Keep up the great work. I’m waiting for your final review on the rx A6A, to decide in buy it or the denon 4700H. I will use it mainly for movie watching surround sound and gaming on next gen ps5 and pc RTX 3080, so I kinda need more than one hdmi 2.1 port.
I always wondered about this. I have 6 ohm Dali speakers and a Yamaha A3060 and i thought you were meant to set Ohms on Amp to match speakers precisely otherwise you could damage the speakers. In doing so it does affect volume considerably.
I have the 3060 to,, I love the receiver.
There's some topics gene will never stop talking about, cables and the impedance selector switch.
That sounds interesting. I wonder what he says about cables? Me thinks I'll go hunt that down.
@@TrevorDennis100 it's snake oil, if you want the abbreviated version of it.
Bought the A6A about a week ago and just today started working on settings and sound levels…. With the TestTone going through the speakers no issue until it came to the subwoofer 1 and 2.
I have a pair of REL G1’s connected to the sub outputs and no sound during test tone and put on a DVD with big bass and again nothing. Subs work fine with my Hegel 390 as well as my Devialet Expert 220 pro using the high level output and the rca output on the Devialet.
Any thoughts that this is an issue with others?
You're right sir, I have been telling people about this for years
Just got my A6A. Love the info.
My Onkyo receiver has the same switch in its speaker setup menu. I assume that any receiver that has this switch should be able to adequately driver 4 ohm speakers, correct? Otherwise, there seems to be no reason to even include the switch if the receiver isn't capable. It's an Onkyo TX-NR727. Thanks!
Kinda starting to wish I waited for the yamaha vs getting the denon. Hdmi works, clean power, looks super nice this time around. Mmmmm
Mmmmmmmhhhhhhhmmmmmmm
THX again Gene.... The empirical proof is in the pudding... ALWAYS.
My machine is RXA2080 but I suspect there to be a lot of parallels here given Yamaha's designs, parts. I didn't put much stock in Eco this and extra loudness that because you run your signal through even more chips and parts correct? K.I.S.S. Keep it simple...
God Bless and long life ole friend.
Is it the same amplifier inside as the Rx z7... thanks in advance
How do you determine what volume your getting the full rated power?
Gene, how does the A6A respond when the balanced outs are utilized for the front mains?
Does that give more oomph back for the remaining channels?
Could you test that for us?
This is the operational mode I was planning on using this product for.
Yamaha a2a, is it worth using the bi-amp? Would that technically be using more than 2 channels? Seems like there would more than likely be a power loss when running my my front L&R only.
Was hoping to have some response on this.
Thank you for the informative video regarding IMPEDANCE Switch..Question...I have the Yamaha TSR 700 receiver...I cannot locate this switch..it isn't mentioned in the manual, so, where can I find this switch, and how do I change it. Thanks!
If it has one, it's likely set to the "high" setting by default. Just leave it be.
English is not my native language and I don't know if I understood it correctly. I have the yamaha a6a with an old jamo 606 set that is 6ohm, so I lowered it to 6ohm on the avr since I read that it could be harmful if I didn't. So, even if the speakers are 6ohm, do I have to set the arv to 8ohm? Will it not harm the avr or the speakers?, thanks!
The video is very clear on the proper setting for ALL Speaker impedance loads. Please watch again.
3070 set at 8ohm with 8ohm speakers, only way go.
Gene I'm using two external amps, so my 3070 is only powering fronts and centre, what roughly would be the power going to these please???
so........will it be ok to hook up 4 ohm speakers to these receivers? I know you said to keep it in 8 ohm settings but just wondering if that's the same for 6 ohm as opposed to 4 ohm or lower?
For the most part yes provided you have good ventilation. If the AVR Shuts down at high listening level, add external amplification on the front 3 channels to lighten the load.
@@Audioholics gotcha, will do. I don't have power amps but I have old receivers hooked up to my pre amp outputs. I have an old denon and an onkyo. trying to get the settings adjusted for those 2 however. I'm not sure if the eq settings in the yamaha affect the output of the 2 receivers I have hooked to it. for instance, when I plug it (my denon) into surround it has no highs (I set my yamaha to have only bass coming out the surround 2 speakers at they are just subs and don't have any mids or tweeters hooked to it). whereas when I plug for instance, the denon into the yamaha's "surround back" and the eq is untouched on that channel then it sounds fine coming out the denon. I'm just wondering if i'm wrong about how the eq works when plugging external amps into the various pre amp output channels or if messing with the eq for the channels that is being used by an amp/receiver will change how they output sound too? or am I plugging the receiver into the wrong pre-amp outputs? Hope I'm making sense here. I might make a video explaining what I mean if typing doesn't make sense.
Gene, what is happening with the A6A? No updates for so long now. Are we still getting a full review from you?
I’m waiting for your expertise and honestly before making a purchase on this product!!!
Bench tests are available on our Patreon.com/audioholics. RUclips video will be live before XMAS.
I have my receiver set at 8 ohms with all the extras off other than Dsp but I often run in pure direct mode for music and movies. I like how pure direct sounds better than straight mode but I sometimes wonder if I just stick to straight mode since I’m using bookshelf speakers and a sub.
@Strong Bull I tend to use straight mode for casual listening and pure direct when I want to focus on the listening
I was under the understanding Yamaha does not use internal fans in the Adventage line. Is that not true??
hi Gene .so i have their 11 channel aventage amp .would you advise leaving that on 8ohm's too?
🤦🏼 Obviously yes
Maybe it‘s for a configuration driving speakers in a surround setup with mixed ohm attributes?
Does yamaha put these protection circuits even in there integrated line like AS 501,801 ??
What would you choose if you had to choose between Anthem AXR 740, NAD T778 and the Yamaha RXA6A?
NAD
1:04 LMFAO! I know that scene extremely well!
I’m guessing the same applies to the A8 as well..
I missed out, how many watts this receiver can set ate 7 ch 8ohms driven? around 60w?
Hey Gene do you where to find the bitrate information on these units
Hi, interesting theory too everyone's take on this topic. I have had quite a few Yamaha over the years and I like the older ones better I have a Yamaha Aventage rx-a2050 and before I had an rx-a1010 I did just the bias to 16.7 it was originally set to 15.2 the services manual does say 15 plus or minus 2% I find it gets a bit hotter with it at 16.7 but sounds warmer to me on the Yamaha rx a2050 I set my bias on all channels to the 16.4 on this receiver and I installed about double the capacitor this unit runs at about 59 too 60 volts plus and minus the unit comes with only 2 * 12,000uf 71 volts capacitor for all 9 channels it seems as the power supply was sagging so I add about a extra 10,000 of 80volt to each rail and it proves they skip out on capacitors for power supply i also changed out the bridge rectifier too a 30 amp instead of the 15 A that was installed on this unit after that i have no complaints about this unit i also add a fan as it does run hotter now but sounds great and drives all my channels with a punch and clarity thats my take on this receiver the new receiver rx-a6a and up use the same amplifier modules just different capacitors but same transistors and layout. I bought mine used it also has two supply rails hookup to a relay at 64 and 37 volts this will switch to 37 volts in the 6 ohm or eco mode or handy cap mode lol if you have small speakers as satellites and are 4 ohm or 6 ohm it will sound better due to the power cut off too 37 volts
In any case all speaker manufacturers lie that their speakers are 8 ohm nominal, so it doesnt matter much
RX-A6A, how do you turn off the touch screen? so i wont turn it on when i clean it.
What should you use when there are 4 and 8 ohm taps on the amp? (e.g McIntosh, Tube amps, etc.)
Use the corresponding tap to what your speakers are. Remember impedance is "nominal" and changes constantly with the music. Heavy bass tracks will be your low impedance stressors, classical music with violin solos are at the other end of the impedance load. Just be sure your amp can handle the load of the speakers, and also be aware when something seems too good to be true for the money...
What if you’re using an external amp? I have a Denon 6500h feeding an Emotiva XPA 7. Does eco mode affect the output of an external amp?
I have a denon X4400h that I run in eco mode with all 11ch being powered by external amps. The only thing that has been affected is the temperature of the unit, with it running about 5 degrees cooler then when I had eco mode off.
Honestly, I tried AV recivers, and get tired of them doing funky busines with sound mixing, crosovers, and what not that is not exatly documented enywhere. Now just running signals in seperate components , pro speaker management dsp and power amp. Plenty of versatility and power. For a home gamer type AV reciver is way to go, less hashle, and almost plug and play. With pro gear you need to know what you are doing. I personally prefer pro gear.
Great! Any plans to test the RZ50 onkyo?
I will never understand why so many people are still interested in Onkyo after all the crap they pulled over the last 15 years.
Thanks…one Day it would be nice to see how you set up the test so we can emulate
Is there a way to see the bitrate of the input source
Gene, I'll bet a dollar that the guys who tell you the lower impedance setting sounds better with 4 ohm speakers are the same guys who say their expensive aftermarket power cords sound better too...
they do..
@stephen sheldon i agree.didnt say they had to be expensive.all of mine are custom made with materials totalling around £ 50 - £ 100. sound good enough..
Tell you guys what. Why don't you go to the Audioholics forums and start a thread talking about the awesomeness of aftermarket power cords?
It should spark an interesting discussion...
Lol
While you're at it, why don't you take a look at the many, many articles gene has written on the subject where he breaks down how silly this idea is from the viewpoint of an electrical engineer...
@@Pohgrey i already have done. ive got to admit they do. but if you want to think the other way ,thats your choice. ive been listening to gene for many years and i do agree with him. but i also agree with all others like paul from ps audio. and many many others. if it wasnt the case that the sound changes from cable to cable,then every one would just use cheap wire. but thats not the case. and im sure youve spent as much money as you feel is right for your system too. right? its just the way this cables debate goes. ive come to a conclusion that both parties are correct.
Thanks for the info. Interesting. I guess my first instinct was that the impedance switch is there to protect the speakers as much as the receiver. Is keeping it at 8 rather than 4 Ohm going to have any affect in the speakers at high volumes? Cheers.
Sounds like I should be good with power. I just brought the 1723s THXs to go with this. Moving on from my Aperion Grand Versus 1s. Wife doesn't know yet? Cross that bridge when I get there.
Is this just a Yamaha issue or for any manufacturer with a 4-8 ohm switch
Any AV receiver that has an impedance switch will severely limit power in the low setting.
Excellent video!! Thank you!! 8 Ohm here
Thanks a lot for the video, very interesting .can you tell me if the rule of leaving the impedance set at 8ohm also applies to the Yamaha R-N803 on a two channel system driving two Elac dbr62? thanks again

What's your assessment in 2021 of quality/value of pairing Yamaha with a pair of REVEL F36 towers? (80% movies / 20% music) .. SVS PB2K subs || Note, the question is.. F36's vs. possibly getting SVS Ultra's instead.
My receiver doesn't even have impedance switch, but my highs are much more detailed and airy, mids are chocolatier and bass is much tighter when I switch it to 4 ohms.
but you said your receiver doesn't have the switch.
Would using the Altra center speakers standing up as lefts and rights sound better than the Ultra book shelf’s them selves.
I had the same thoughts about the ultra center as left and right speakers, it's almost like having the ultra towers without taking up all that space especially if you also have a sub. Let me know if this is what you have.

@@normrubio LOL, I like that! :)
Hi there guys Ives been a fan since you first got covid lol. I have a question that's a bit off topic. I bought a new theater system and I followed your subwoofer setup videos. I have an R 100sw klipsh sub and my av reviewer is the Onkyo TX-NR595. I set the crossover on the reciver to 80hz and the level on the sub to 50%. When I run the automatic setup it sets the sub to +3db. Problem is, when I play any movie it just rumbles the whole time unless I turn the level down to about 25%. Any help from the community would be appreciated.
Is it truly bass rumble? Or vibrations? Make sure the sub is isolated from anything it can vibrate. You may then find that you just hear low movie bass as you should. The speaker tests are a quick punch - not a sustained bass track like a movie. I isolate front firing subs on a thick rubber paver on top of a 2' x 2' concrete paving stone (Home Depot landscaping area). For floor firing I isolate on the same but on top of the rubber pad I add a 2' x 2' x 1" thick square block of hard wood. Looks like a weird smore but prevents the sub from vibrating the floor or anything around it.
If you have 4 ohm speaker and if you are so much concerned, just add a 2 ohm resistor in-line and that would be better!
Thanks for a very useful video trying to help audio enthusiasts like me extract best performance out of the sound investment we have made.
Have a question on this. What happens if I have pre-amp outed the front speakers on to a two channel Yamaha power amp MX 600, from a Denon X3600H receiver. MX 600 also has a Impedance switch at the back which I have left as 8 ohms as per your advice. Your graph on 2 channel driven performance doesn’t seem to have much of an issue.
Thanks once again hoping to receive a reply.
Regards
Now some guy with his 9 Channel JBL speakers playing reference level sine waves while at work to break in his new speakers and wondering how his house burned down. I kid but I wish you would have at least given a brief explanation of why this setting exists. I know you've hit on it in your previous videos, but I'm sure you made some poor electrical engineer at Yamaha cringe saying you would never under ANY circumstance use anything lower than the highest impedance setting. Love the video though, always appreciate the graphs.
I've covered this topic ad nauseam already: ruclips.net/video/Ou5bO8P2Drw/видео.html
Great tip! Tks Gene
Back before I knew better . I was using the 6ohm setting on my Yamaha a2080. My q acoustics are are 6 ohms. But after watching one of your videos from a while back. I put it back on 8 . But I have moved onto separates now. With a monolith 9x.
Can anyone let me know if this yamaha a6a receiver has a better sound than the onkyo rz50? I'm not sure wich one has the best home theater sound.
Yamaha is a better amp, great 2CH performance.
@@Audioholics how about the a8a vs cinema 40/50?
yamaha rx-a2a aventage is only 24ibs that's not a good thing in my opinion. If it has seven channels and comes in under 30 lb that makes me shy away from it.
7 channels driven and only 50 watts... even when leaving the impedance at 8 ohms? Still..?! Why?! Come on Yamaha!
Thx for the vid mr G
Why are you wearing headphones whilst talking to camera? Seems a bit odd so what are you listening to?
I switch to 6 ohms and definatley noticed it was limiting current, switched back to default 8 and left it there, sounds better and louder with less distortion , yamaha system too.
