I just purchased and received the EZY DSP68 based on your review of the software. Haven’t had a chance to install it yet though. Your work is awesome. Thanks so much!
@@hooptastic_hippie8522 Ha, that would be quite a trick. However the software, not the device, was reviewed on this channel 3 weeks ago. You should check it out.
Hope you're willing to edit you comment to add a couple asterisks... For this model year? Maybe. Domesticly? Possibly. King? Try again. I have a 3 year old DSP that blows every spec this thing has out the water (except # of channels, which the overwhelming majority of people won't use) that's imported and still costs a base cost $50 less than this one that's on sale.
@AppAccess123 how are you going to tell everyone that you have a better/cheaper DSP but not tell us what it is? Some of us are actively looking for a new DSP
They really killed it here. I love the USB"B" port. I use one in my car and anywhere else I can. FYI I don't believe there's any RCAs that screw into the Tiffanies, They just create a much more solid mounting when they can sandwich the case. This is a really solid unit. I'll stick w my helix of course, but They really put some thought into this here.
@@RAW-CAtThe panel mount design holds everything very rigidly. The other style is known to move around a little bit when you plug RCA's in and out and that can cause the solder joints on the pcb to get weak and break.
This DSP would be a no brainer for me if it had the import function that Helix has and I’m betting that it doesn’t. It’s such a pain in the ass to manually input PEQ values from REW. I don’t know why other DSP brands don’t incorporate that function into their PC based control software. It can’t add that much addition cost can it?
Love your vids and honesty. I have enjoyed the down 4 sound products and have been waiting to see the easy dsp and equipment. Keep up the vids bud and I have been watching your vids a long time and enjoyed your content . And thank you.
Oh damn... I was expecting Chinesium, but it has a ADAU1452. Same units as used in many expensive DSP (Helix DSP PRO has 2). I noticed they have refurbished units in their shop already. Not sure that's a good sign given that it's not a very old DSP yet. So going down the left it is BT radio, sample rate converter (ASRC), DSP (the ADAU1452), main CPU (STM32). ADC/DAC in the middle section, with the PSU on the right. Could probably increase the sample rates over 48kHz with improved ADC/DACs. Speculating, not a engineer, just someone who tries to do homework, etc. (i.e.I'm cheap 😄) I was interested in the 8ch, I don't need 12 at all, but the fact you mention it performs slightly worse tells me we're missing some shielding somewhere since components would probably be closer. Some of the high-end DSP I've seen have several voltage regulators to make sure voltages are always being regulated which would help reduce the noise, etc. I wonder if the layout is causing it not to match the Helix? The layout seems to be built off blocks, sort of pick from shopping list or catalogue. Might not have offered the best signal routing; something Brax/Helix would have spent more time on perfecting, I think. So for the 8ch it is like a worthy replacement for the old miniDSP C-DSP 6x8 especially considering price point (miniDSP 2nd hand often $250 these days). I hope they don't bump up the price on these. I see on their site the 12ch is "on sale" for $400, but marked down from $600. Thanks for your tests! So who is going to be my Secret Santa this year?
Not to defend them but many brand and retailer would mark some inventory as "refurbished" as a way to lower the price without lowering the real MSRP or get in trouble with the brand MSRP rule. I bought many products labeled as "refurbished" at marked down price but practically brand new.
Ahh Mr. Raw Cat. Nice to see an unbiased review. I was sad to see williston audios unbiased reviews end when the D4S "affiliation" began. After he started simping for D4S, everything he reviews he treats aa substandard to anything D4S makes.

@everyangle4310 Do you use an iPhone/iPad or Android smartphone/tablet??? If you use Android, get a separate Audison B-con Bluetooth Receiver which supports LDAC and has both RCA Analog and Toslink optical outputs (including a Toslink In/Out pass-through). You can connect this directly into your DSP to bypass the POS OEM Toyota head unit (they really are terrible!). If you do this, you will need to make sure to Enable and go into the Developer Options of your Android device and change the Bluetooth settings to "Highest Quality" + 990kbps/900kbps. Otherwise the wireless BT connection will default to the lower 660kbps or even 330kbps, which are no better than the standard SBC or AAC BT codecs. The B-con BT receivers also have excellent signal strength and connection range! I have the Audison B-con BT receivers installed in TWO of my vehicles. I tested the first one in my home studio using my high end studio monitors. When the LDAC codec was used and set to Highest Quality & 990/900kbps, the Sound Quality was indistinguishable from a 100% Lossless hard-wired connection for 95% of music. And for the other 5%, it was extremely difficult to notice any differences at all...and that was in a Quiet studio environment, not while driving a car! OR, you can get the Axxess Interfaces # AXDSPX-TY3 OEM Interface and DSP complete with vehicle-specific T-harness. You can use this with your OEM head unit, OR install a good aftermarket head unit like the Kenwood eXcelon Reference DMX-1057XR, and the Axxess interface will retain the OEM your Steering Wheel Controls and other OEM features and functionality of the OEM head unit (confirm with Axxess Tech Support). You don't have to use the DSP that's in the Axxess interface if you already have a DSP. But the interface automatically reprograms the OEM Head Unit so that it will output a CLEAN, FLAT, FULL RANGE, RCA Line-Level audio signal and removes any of the factory processing in the head unit, and provides a set of Front, Rear, and Subwoofer output RCAs.

The coil next to the power plug that you're calling a transformer actually looks like an inductor. It looks like a single loop of wire. This would probably be used for filtering noise coming into and going out of the 12v wire. The smaller coil actually looks like the transformer. It should have multiple different loops of wire and 4 or more solder joints to the board.
@SeanOMatic Thanks for the confirmation. I see them all the time in the better quality amplifier brands like Kicker and Rockford. Most of the cheapie, clone amplifiers don't have them. I know inductors/chokes roll off upper frequency AC signals by 6 dB/octave. I'll have to remember that in this application it's called a common mode choke. 👍
@JasonWW2000 Tony D'Amore sells amps with a patented technology called "Clean D" that is literally just a common mode choke and output filters. You see them on a lot of amps, as they are a cheap, effective way of cleaning up noise on the B+.
@SeanOMatic Yes, I've seen them on those amps. (BTW, I think he does additional things besides just adding chokes) You'd think all manufacturers of class D amplifiers would use them just so they didn't backfeed noise into the vehicle and potentially cause problems. But no, they want to make it as cheaply as they possibly can. SMH
The Dayton barely puts out 2v over the RCAs and overall I would avoid it unless your budget is actually limited to that amount. I would urge you to simply wait and save money for a better unit. ;)
I'd send you may Dayton. Maybe you can prove how crap it really is. Would not keep setting constant. Have to erase and reload settings every time I disconnect it from power
I think there’s a review of the Dayton on the ASR forum. Not sure so you’ll have to search it. I do know that the Dayton is very noisy. I helped a friend install one in his vehicle and tuned it for him. The Dayton actually runs on AC or DC and comes with the AC plug and transformer. Some people actually run it on AC in their vehicle with the addition of an inverter and say the noise issue improves significantly. The only other way around the noise issue that I know of is to have such a low level output that the noise becomes inaudible, but then you really sacrifice dynamics with the decrease in volume.
Thank you for the feedback. Last question, is the 8 channel the same as the 12 but just has 4 channels less? I am seriously looking to order a new dsp.
@@19rc69 Use a 12v dc to 12v dc converter if you have noise issues related to the power. Seems to be hit or miss some have it some dont so could also just try returning it for another. The og ones also had noise issues related to the controller/knob as well which was fixed on the new controller. If you look partsexpress has 2 different controller part numbers and thats why. Better bluetooth with these for sure and more channels and more eq bands. Both use analog devices dsp chips adau1452 on this one and 2x adau1701 in the dayton.
@@RAW-CAt Hey rawcat I’m stuck on an issue and I have no one else I can ask. I’m getting vocals through my sub even through I tapped from my front signal and went through a kicker keyloc. I tried 3 different amps, a different loc, even tapped off different speakers and tried another sub but same issue. My last resort is to fully eq everything off a dsp and hope it fixes my issue. lPF is set to 80Hz and still plays vocals on 20Hz also
@@ssjdavid some male vocals can be even below 100Hz. Remember that a crossover is not a brick wall so if you cross your sub at 80Hz, it will still play 100 and even 150hz. What crossover slope did you use on your sub. Maybe try a steeper one?
@@RAW-CAt right now I’m just using my crossover on my amp to control everything but I have a ezy dsp I can hook up to manually crossover everything do you think it’ll help if I add it?
If you have tested the alpine pxe-850x. How does it compare to the d4s ezdsp. From the look of the specs I should have waited a year and bought the ezdsp instead.
Well, it needs power, ground and remote in like any other head unit or amplifier. The marking on the power plug tells you where things go. I would recommend using a 2A inline fuse for the positive wire.
@@RAW-CAt sad, there are many remotes that use the same RJ45 connector, i wonder if any of those would work 🤔 Digital input/bluetooth don’t work without volume control right ?
@@RAW-CAt, thanks for this information. It's very important to know. I was wondering about this. I will adjust my gains accordingly when installing this.
@@JasonWW2000 No, it isn't exclusive to HELIX. You can even do differential rear fill with some simple wiring tricks and an inexpensive ($40) pro audio mixer. However, I would propose that standard stereo rear fill with delay, reduced levels, and band-limited will be just as effective and will work properly with a wider variety of music. Depending on what tricks or EFX were applied to the music track during mixing by the engineer, differential rear fill can produce some very odd and undesirable effects.
@bbfoto7248 Just to be clear, do you know what it is? Some of the aspects of it can be duplicated, but removing the right percentage of mono information requires sophisticated processesing. Other than Audiotec Fischer, I've not seen any brand of dsp capable of this.
I haven't tested the minidsp. However those have iir filters, which might be superior if done right. Minidsp is a different beast, especially with dirac live. you can't compare them directly.
When trying to download the app for Android I keep getaway message that says I don't have a app that can open this file and prompt me to download from play store, do you know what att is needed?
@RAW-CAt yeah i know but I have the dayton dsp, mann engine noise is killing me and yes I wire every ground I could think of....after watching your video I decided to purchase this, I all also used your code
$400 is a little much for, at best, a "B grade", DSP without a remote. One big point is its 4-volt max output. My HU is tested clean up to 5-volts. By using this it would be cut back to 4-volts, a 20% drop. The real budget king is the Hertz S8. Comparing this to the likes of Helix and Mosconi is laughable. Both have a build quality and level of refinement that is "light years" ahead of this.
Your mentioned S8 has the same 4V out, no remote as well, only half the EQ bands and no all pass filters. In the UK it's ~£550,for that price I would get a Helix. And we have no idea how clean it is🤷 I am not sure what is laughable about the comparison if I showed actual objective data that is comparable. I am co.paring the cleanliness and perfo.rnace, NOT functionality or software. And I don't actually remember mentioning Mosconni at all🤔
S8 uses the adau1451 d4s uses adau1452 as far as capabilities of the chips go there isnt much difference 1452 has more memory thats the only difference between the 2 chips. With the d4s 8 channels advertised clock speed I bet its got the 1450 which has less memory again and a 147.456 mhz clock speed. Also no spdif and a few other things. These are both good options though, depending on your needs one might be better than the other.

It's not "Alpine software", it's a generic software that many DSPs use, Alpine is one of them. They just put on a different skin. With a brand logo.
So many DSP's use this software. It's licensed. D4S doesn't have a software development team.

I know inductors/chokes roll off upper frequency AC signals by 6 dB/octave. I'll have to remember that in this application it's called a common mode choke. 👍
@JasonWW2000 Tony D'Amore sells amps with a patented technology called "Clean D" that is literally just a common mode choke and output filters. You see them on a lot of amps, as they are a cheap, effective way of cleaning up noise on the B+.
@SeanOMatic Yes, I've seen them on those amps. (BTW, I think he does additional things besides just adding chokes)
You'd think all manufacturers of class D amplifiers would use them just so they didn't backfeed noise into the vehicle and potentially cause problems. But no, they want to make it as cheaply as they possibly can. SMH
Have you reviewed the Dayton Audio DSP4X8? It’s also a very good DSP for the cost, in the US it retails $164.00.
No, no one sent me a Dayton so far.
The Dayton barely puts out 2v over the RCAs and overall I would avoid it unless your budget is actually limited to that amount. I would urge you to simply wait and save money for a better unit. ;)
I'd send you may Dayton. Maybe you can prove how crap it really is. Would not keep setting constant. Have to erase and reload settings every time I disconnect it from power
I am embarrassed to ask but how does it compare to the Dayton 408? Sorry, new to DSP world.
Never tested the dayton, can't say🤷
I think there’s a review of the Dayton on the ASR forum. Not sure so you’ll have to search it. I do know that the Dayton is very noisy. I helped a friend install one in his vehicle and tuned it for him. The Dayton actually runs on AC or DC and comes with the AC plug and transformer. Some people actually run it on AC in their vehicle with the addition of an inverter and say the noise issue improves significantly. The only other way around the noise issue that I know of is to have such a low level output that the noise becomes inaudible, but then you really sacrifice dynamics with the decrease in volume.
Thank you for the feedback. Last question, is the 8 channel the same as the 12 but just has 4 channels less? I am seriously looking to order a new dsp.
@@19rc69 Use a 12v dc to 12v dc converter if you have noise issues related to the power. Seems to be hit or miss some have it some dont so could also just try returning it for another. The og ones also had noise issues related to the controller/knob as well which was fixed on the new controller. If you look partsexpress has 2 different controller part numbers and thats why.
Better bluetooth with these for sure and more channels and more eq bands. Both use analog devices dsp chips adau1452 on this one and 2x adau1701 in the dayton.
@@Randy_G Need to see the internals but if it has the same dsp chip it could be the exact same thing minus 4 outputs.
Which digital sample rate did you use for measurements and what is the highest digital sample rate can be used for input for this unit
I used 48 for digital signal as that is capping the DSP. I measured the analogue section at 96k. The DSP is 48k.
Is it worth returning the 6-8 and getting the 6-12? I don’t need the extra outputs to be honest
Nah, keep the 68. There is a difference, between them, but doubt it's noticeable at all.
@@RAW-CAt Hey rawcat I’m stuck on an issue and I have no one else I can ask. I’m getting vocals through my sub even through I tapped from my front signal and went through a kicker keyloc. I tried 3 different amps, a different loc, even tapped off different speakers and tried another sub but same issue. My last resort is to fully eq everything off a dsp and hope it fixes my issue. lPF is set to 80Hz and still plays vocals on 20Hz also
@@ssjdavid some male vocals can be even below 100Hz. Remember that a crossover is not a brick wall so if you cross your sub at 80Hz, it will still play 100 and even 150hz. What crossover slope did you use on your sub. Maybe try a steeper one?
@@RAW-CAt right now I’m just using my crossover on my amp to control everything but I have a ezy dsp I can hook up to manually crossover everything do you think it’ll help if I add it?
@@ssjdavid on the amp turn the crossover all the way up. Use the crossover on the DSP only.
Do I wait until the controller drops or should I grab one now? lol
I would grab it before the price goes up. The controller will not be expensive to add on later.
Coming soon.
@@RAW-CAt probably. 😂
@@D4S-JAKE Have you guys decided on what model controller you're going to use?
I dont like the "amp" shape either. It makes it only complimentary to their amps. As a stand alone DSP it should be able to look good in any install.
Does it not match your skinny jeans well enough.
@@Dingleberry1856 Your correct. Doesn't match your dress either...
If you have tested the alpine pxe-850x. How does it compare to the d4s ezdsp. From the look of the specs I should have waited a year and bought the ezdsp instead.
Alpine is not as clean and has lower output voltage of 2.7V. as well no all pass filters for the Alpine. Other than that, everything else is the same.
@@RAW-CAt it’s sad the alpine cost so much more. Thanks for the info
Is this thing possible to use with a factory radio??
You need a version with high level inputs.
I have many DSP´s in hand from american brands, if i buy the same products you are using for measurement could i send you the information i get?
You can publish the data in Distortion Factory group youself😉
I recently bout the ezy dsp612 with no instructions on how to properly power it or fuse it I need help before I begin my project
Well, it needs power, ground and remote in like any other head unit or amplifier. The marking on the power plug tells you where things go. I would recommend using a 2A inline fuse for the positive wire.
@@RAW-CAtI may have missed it in the video but what size power wire is usable.
@@OKstang77 for 1A of current probably 18-20 gauge will do.
Is it possible to use high-level input for OEM headunits or only RCA's
Unfortunately bassheads don't do factory integration. There are plenty of those options on the market.
You need to use some high quality, inexpensive LOC's. Like $20 Kicker Kisloc. Problem solved.
Any update on Remote for this? Its all thats missing
So far nothing🤷
@@RAW-CAt sad, there are many remotes that use the same RJ45 connector, i wonder if any of those would work 🤔
Digital input/bluetooth don’t work without volume control right ?
@@cnkyy of course they work, you just set the priority in the pc software.
@@RAW-CAt oh i see, i didn’t think optical supported volume but i haven’t used it myself
So if I have a head unit that puts out 5v on 6ch, will the dsp put out 5v @ 20 dbu?
No, the output is still limited to 3.8V no matter the input.
@@RAW-CAt, thanks for this information. It's very important to know. I was wondering about this. I will adjust my gains accordingly when installing this.
Can it do differential rearfill?
No, it cannot.
I believe that is a exclusive feature of helix dsp's.
@@JasonWW2000
No, it isn't exclusive to HELIX. You can even do differential rear fill with some simple wiring tricks and an inexpensive ($40) pro audio mixer.
However, I would propose that standard stereo rear fill with delay, reduced levels, and band-limited will be just as effective and will work properly with a wider variety of music.
Depending on what tricks or EFX were applied to the music track during mixing by the engineer, differential rear fill can produce some very odd and undesirable effects.
@bbfoto7248 Just to be clear, do you know what it is?
Some of the aspects of it can be duplicated, but removing the right percentage of mono information requires sophisticated processesing.
Other than Audiotec Fischer, I've not seen any brand of dsp capable of this.
So .. in your opinion.. is it better than the MiniDsp C-DSP 8x12 DL ?
I haven't tested the minidsp. However those have iir filters, which might be superior if done right. Minidsp is a different beast, especially with dirac live. you can't compare them directly.
@@RAW-CAtIt would be fantastic if you could test the Harmony DSP 8x12. The ASR folk seem to think it's pretty good.
Does anyone know the measurements of this unit? I can't find them anywhere.
7x6x2 in inches.
@@RAW-CAt I bought it on your recommendation but forgot to use your code so I sent you 10 dollars on pay pal
When trying to download the app for Android I keep getaway message that says I don't have a app that can open this file and prompt me to download from play store, do you know what att is needed?
You need to enable "installing from unknown sources" in Android.
Just out of concern does this give engine noise
Why should it? Engine noise is a problem with wiring and grounds, not equipment.
@RAW-CAt yeah i know but I have the dayton dsp, mann engine noise is killing me and yes I wire every ground I could think of....after watching your video I decided to purchase this, I all also used your code
@@nileshudson2185 the dayton has noise issues reported by many users...
Well..i need 400 bucks now
There is the smaller version for cheaper😉
What percent of distortion can the average person even hear? I doubt it’s even close to 0.05%.
Well, speakers have distortion of around 0.2-0.5%. Audible distortion is on a similar level 0.5-1%
Not a fan of D4S👎.. BUT.. if it comes with with a controller at the same price.👀..I guess I will have to buy it ... But it is ugly 🤣
yeah id much rather have a plain case without anything related to d4s on it.
I'm sure the controller is going to cost extra.
@@666nacirema666
Just paint the d@mn thing whatever color you want, LOL.
@@JasonWW2000
Maybe. But I doubt it'll be more than $40.
on first look I don't like the look at all, just look out of place
$400 is a little much for, at best, a "B grade", DSP without a remote. One big point is its 4-volt max output. My HU is tested clean up to 5-volts. By using this it would be cut back to 4-volts, a 20% drop. The real budget king is the Hertz S8. Comparing this to the likes of Helix and Mosconi is laughable. Both have a build quality and level of refinement that is "light years" ahead of this.
Your mentioned S8 has the same 4V out, no remote as well, only half the EQ bands and no all pass filters. In the UK it's ~£550,for that price I would get a Helix. And we have no idea how clean it is🤷 I am not sure what is laughable about the comparison if I showed actual objective data that is comparable. I am co.paring the cleanliness and perfo.rnace, NOT functionality or software. And I don't actually remember mentioning Mosconni at all🤔
S8 uses the adau1451 d4s uses adau1452 as far as capabilities of the chips go there isnt much difference 1452 has more memory thats the only difference between the 2 chips. With the d4s 8 channels advertised clock speed I bet its got the 1450 which has less memory again and a 147.456 mhz clock speed. Also no spdif and a few other things.
These are both good options though, depending on your needs one might be better than the other.
I’m using a DSP with 0.0017 THD
Nice 👍
