Man you are the most thorough car audio teacher ever on the internet, you put the industry to shame with their sell everything but explain nothing to the consumer. Imagine the equipment people would not or would have bought if they understood what it does and how to use it. Every dsp company keeps everything murky but at the same time throw tech data at you like the average consumer helped build it or something. I appreciate this channel more than any mobile class I seen or been too
It’s true. I’m old now, and this is the first set of videos that put all of this stuff together. It’s not rocket science after all, but this industry runs on rumors and opinions. Thanks for taking the time to explain so many things. Leave these up. I reference them a lot.
It would be useful if at least official resellers of known brands that also do installment and tunning, would know what they are doing. I bought mosconi gladen combo with official reseller in our country and they suppose to do tunning even for competitions, but what I have got was disaster. I have spent tens of hours of learning and trying to properly tune system. Now system is light years better compared from what I have got from tunning guys. They did correct only time alignment. Everything else was dead wrong.
I love that you’re using the same oscilloscope that they trashed me in your group for using to set my gains 😂 Facebook users are some funny people, Mr. Nerijus. Thank you as always for what you do for the community.
Another excellent tutorial Nerijus, thank you. Edit. I just went and moved all of my gains to 2V (5V source). I will have to redo my eq because I must’ve had distortion but even as is, its nothing short of a magical transformation. I have so much more tone in the bass and the highs are so clean. Fabulous. Even the led “power” meter in my old Alpine eq now tracks in parallel with volume.
Very interesting! I always thought my gain was off, but now I reduced it by 30% since I don’t need the extra power. I definitely prefer a cleaner sound over 100% output. Also, it’s important to test if your head unit clips, so you can fully trust your setup. Thanks! I really appreciate your work you helped me understand how gain works, and it makes so much more sense now. Thanks again for sharing your knowledge ❤
What are breath of fresh air. I've been preaching speaker efficiency/sensitivity and head room forever it seems like. Still people want to buy the hyped up brands they see on RUclips thinking that's the only way to be loud. In my car I have a 400 watt amp on mids and highs, and a 1500 watt amp on one 12 inch sub. When people get in they're shocked at how loud and clean my stereo is. They ask what it meters and when I tell them. They say that's not possible with that much power and one 12. Terrific video, terrific channel!
Yup. Keep the amplifier gains low, and keep the source/DSP/EQ gains as high as possible. In the pro audio world, we call this "gain staging". You want the loudest, cleanest signal from the source and then apply as little gain as possible later on, because each time you add gain, you are also amplifying the noise floor. High volts from the head unit if possible, and high volts from the DSP, will ensure clean, low-noise signal going into the amp.
LOL, I know that feel all too well when I first started DJing and had crappy audio interface and mixer, high end suffered especially with the stage monitors.
What about amplifier input sensitivity? I know you want to send the cleanest signal as possible to your amplifiers. Is there such thing as sending, “too hot” of a signal to the amplifiers? Let’s say the max input sensitivity of an amp is 6v. If you send anything higher than that, would that lead to problems?
Using a 0db source signal is certainly the safest option, but for low power systems, you may find you don't get enough volume out of music that is recorded at lower levels. I usually start with -6db signal to leave headroom for quiet tracks...but with a modern DSP connected to an old school amplifier, you're always going to end up with gains set to minimum.
I agree with everything said here. BUT there is one thing to remember. Alot of us are constantly tinkering and messing with things. So for those that don't want to constantly readjusting gains every time you eq or change speakers or config. You can make some simple rules on yourself. If you set gains at at 0db. Then when u eq. don't boost above 0db(overall boost as you mentioned) Or leave your self some leeway. set gains at +3 or +6db output. then you'll forever have room to boost to those levels without clipping. This all also assumes at some point you're gonna play FULL 100% volume. so you're actually reaching the full +6db boost at that point.
I still like to set all my gains before I start EQing, with all the levels and EQ set to 0 on the DSP. Just because I don't trust the manufacturers. E.g. the helix dsp.3 says it outputs 6V, but I measured 6.7V out from mine with the BT Hec card. I'm not complaining, but I had to turn the DSP down 1.5dB so I got 6V, then I had to turn up the gain a little on most of my amps to get the rated voltage, even though their gain was rated to 6V. Then again, if you have very insensitive drivers, you can often turn the gain to +3 or +5dB, because most music is mastered to a -5dB level or lower, and you will get "more output", or actually rated. In a full SQ car it is pretty irrelevant, but if you e.g. want to play with the doors open some time or something, you can easily blast at full volume and can then cause clipping if the gains are not set. Of course when the gains are set with 0dB from the DSP, you'll have to always keep the maximum level at 0dB too, with level and EQ.
Wait? What level should the head unit and amps set at to actually set the DSP EQ? That way then I can go back and set the gains for the amps? I normally just set everything with an Oscilloscope. I was lucky I have clipping indicators on my JL Audio 900/5
I think I prefer the old way of √(p*r) while playing a 50-60Hz tone close to 0dB better so you don't overload the speakers and will have the exact gain that you need.
This method is a step up, but keep in mind: the lower the frequency, the more power is required. For example we can often run 500 W to a sub but only need 15 W for a tweeter to produce the same dBu. This is why the highest EQ boost frequency is not always the clipping danger frequency.
Correct. As I mentioned in the video, I do not recommend setting gains for mids and tweets up to clipping. I am just demonstrating an example because everyone is asking.
Do I need to mess with gain on my DSP/AMP helix combo(m six dsp) if i use optical as input? How does gain work with optical as input? assuming highest EQ is at 0db or no EQ at all? Thank you for this.
93dB sensitivity with 1 watt, EMMA SQ judging is at 85dB. I clamped all the channels on my car at 104dB at the headrest, Mids and tweets less than 1W, midbass was 1W, front sub was 7W trunk baffle sub was 180W. I have all my gains all the way down except for the subs, so I don't bother with them either. I have a question though, if you adjust your gains after then doesn't that messes up your levels in your tune? So it's better to match DSP to amp at the beginning and just have headroom, like you said. i think there are so many "adjusting gains" videos because people treat it as a volume knob.
It does mess up with the level matching indeed. It would be a back and forth game checking and adjusting. The only time I had to adjust the gains on an amplifier was after cutting midbass with EQ (to get rid of the cancellations) and then bringing the level up🤷
Thoughts on setting gain with a sweep over a singular sine wave let’s say a sweep 25-150 you make a smooth response with an O scope from let’s say your box is great from 32-60 hz so I make a smooth response as much output as possible without clipping from 30-80 with the sweep instead of just let’s say a singular sine wave 30 hz and a 40 hz because that would mean my music plays well from 30 through 80 with no clipping compared to just music that plays at 30 and 40hz. Been tuning all my subwoofers like this when it comes to gain it always sounds great compared to using independent tones just wanted your opinion.
In my opinion, there is no need to reinvent the wheel🤷 It does not matter what your subs or box is playing , for setting the gains all that matters is the electrical signal. And if using a DSP, that signal is clearly seen in the individual EQ window.
Well good. But what about the calculation people does it while doing gaining amp that ( √ohms×rms) and match the voltage of AC voltage by using multimeter. And can we measure the volt comming in RC by using multimeter.?
The calculated voltage is a very rough ball park as it takes into account a lot of assumptions. For example it is an assumption that at your voltage the amplifier is making rated power. As well it is an assumption that the ohms value matches the speaker impedance. I would not recommend to use that method.
You should not have to change the EQ, all should be fine. You might want to double check the individual speaker levels though just to make sure the system is perfectly level matched.
@@RAW-CAt basically as you know at every frequency there are layers of different sounds. Well when you add to a frequency it pulls the very top layers first causing uneven gain from the top Layer to the bottom depending on level. Opposite is true for cutting. It basically smashes the layers together. I know this for a fact. For one I could hear it and afterwards dug into the topic. Real issue studios deal with. My daughter plays live music and is a communications major in college and we've talked about this subject and the audibly of it. I also know this is way outside most people's interests.
So i’m torn for a dsp after your last vid. Was going to go the ez dsp 12 channel. But now i’m debating if i should just get a minidsp and upgrade to drac live later? I’ll probably be gravitating more toward spl in the future rather than sq.
Choosing a DSP is a difficult thing. The good thing is that you don't have to stick with it for life. If you won't like it, you can try something else.
Very useful video. But I have a question. I have a Helix DSP.3S which outputs 6 Volts connected to an Audison APBX 10 AS2 which has a gain of 0.1 ÷ 4. So I put the gain on the Audison sub on 4 but there is no bass. I tried fixing it from the DSP but it didn't work. The Audison sub also has a Bass Boost knob from 0 to 6 db. Should I use the Bass Boost or up the gain on the sub amp to get some bass?
so my current head unit has 2V output, yet my Helix DSP has 6V output...im a bit confused about matching the input to the dsp and then the output to my amp.
Helix DSP has input sensitivity, it can be gain pots next to RCA inputs or jumpers inside the DSP. You need to look at the manual of your particular DSP model.
In your example you set your gain to be optimized at 450hz because it was the loudest frequency in the dsp. Why would it clip at 900hz if the eq was flat at that frequency? Wouldn't everything not clip anymore because it would be quiter than 450hz?
I’ve noticed that my Helix DSP3.s will only put out its max(6 volts) with the channel gains at (+ 5). My amps accept 6 volt input. Should I just leave the channel gains at “0” and amp gains down and adjust the DSP channel outputs if I need more volume ?
Quick question. Isn't it the case that in order to use an oscilloscope and get correct readings from it (as well as from multimeter) you need to disconnect speakers from amps?
You can have the subs connected, but mids and tweets you will blow. I never recommend setting gains for mids and tweets, but since people keep asking, I made the video🤷
Knowing what I know today about tweeters and power, the output wattage of the amp really is irrelevant. They're only going to use 5 watts at their peak. A good 25wpch amp is prefect.
Yes, it will. The only time I personally needed to increase the gains is on a few midbass drivers after cutting a lot with EQ. Never had to do that on tweeters or midranges.
What if say my left mid bass eq is cut at 300hz and boost at 400hz . While right mid bass is boosted at 300 but cut at 400. As per my response scenario and eq requirements. But amplifier gain setting knob is common for these 2 channels. What to do in that case?
You choose the "weakest link". See which OVERALL boost is higher, the 300 on R or 400 on L. As well take into account the channel gain. For example if your l side has +2dB overall boost at 400Hz and -3dB channel gain, you are -1dB in total for the l channel. And if your right side has +1dB overall boost at 300Hz and 0dB channel gain, then your R channel is higher in level, so you should choose 300Hz tone. Hope that makes sense. Just some maths😉
@@RAW-CAt just want to say thank you! You are absolutely right! I turned them all down, just had to raise the midbass and mid-range channels a smidge to bring them up to the tweets level, as they played the loudest. After I was done with the EQing/tuning, I had plenty of output. Prior to this no matter what I did I was never satisfied with the output and was doing all sorts of cutting back on channel levels, especially the tweets.
The problem with DSP amplifiers is exactly that - there is no gain. So if you are not careful with EQ, you might end up cutting too much and will not be able to bring the level back up. You need to be more considerate.
All oscilloscope isn't the same i had aukuyee for years same head unit volume is 34 is distortion 50 max using rca now i have this fnrsi volume show me 29 is distortion 50 max do it again show me 50 max no distortion i had to listen with my ear and i see 34 is distortion i will buy smd dd-1 so i don't have to pluggin power ,aukuyee is good

Completely incorrect. Not everyone can afford higher volt source units, hence why there is input sensitivity setting for matching. Please spread correct information and not just your own opinion on things.
Can you please specify what exactly is incorrect? Talking about higher voltage source it is my advice and opinion. I am not stating any facts that can be incorrect🤷 I'm confused...

You choose the "weakest link". See which OVERALL boost is higher, the 300 on R or 400 on L. As well take into account the channel gain. For example if your l side has +2dB overall boost at 400Hz and -3dB channel gain, you are -1dB in total for the l channel. And if your right side has +1dB overall boost at 300Hz and 0dB channel gain, then your R channel is higher in level, so you should choose 300Hz tone. Hope that makes sense. Just some maths😉
So my DSP outputs 6v and my amp sensitivity is 2v-8v, what do I do there?
Increase the gain if you are missing volume.
@@RAW-CAt just want to say thank you! You are absolutely right! I turned them all down, just had to raise the midbass and mid-range channels a smidge to bring them up to the tweets level, as they played the loudest. After I was done with the EQing/tuning, I had plenty of output. Prior to this no matter what I did I was never satisfied with the output and was doing all sorts of cutting back on channel levels, especially the tweets.

Do you prefer to tune with your phone or laptop? Waiting on my first official dsp to arrive (d4s ezdsp)
I always tune with a laptop. I use the phone to test some things, like different crossovers or muting drivers.
What do i do when i am using optical and not rca into my DSP?
Exactly the same. A DSP 4V will output 4V no matter the connection to it.
if you difficult with set gain, just use DSP amp (DSP including Amplifier) no need external amplifier 😁
The problem with DSP amplifiers is exactly that - there is no gain. So if you are not careful with EQ, you might end up cutting too much and will not be able to bring the level back up. You need to be more considerate.
You wiring looks super tidy
All oscilloscope isn't the same i had aukuyee for years same head unit volume is 34 is distortion 50 max using rca now i have this fnrsi volume show me 29 is distortion 50 max do it again show me 50 max no distortion i had to listen with my ear and i see 34 is distortion i will buy smd dd-1 so i don't have to pluggin power ,aukuyee is good
I just had a seizure reading that... do you actually read what you wrote before sending that shit?
Sveikas tavo manymu kokį filtrą ir dazni parinkt štai šiam daigtui priešbosis Helix Match MW 8BMW-D nes mid 10cm rašo nuo 100hz startas bet spėju kad tai melas 😊
~60Hz
-0, -5, or -10db
Your wiring is very distracting, I am used to looking at a birds nest.
Haha, thank you. Some times I do have a birds nest as well. One in a while I make something pretty.
TLDW: Set gains on your sub maybe, everything else, until your ears bleed. (then maybe back it down. lol)
😂
You need to use a white noise and inject it into the system..to do this freq by freq is totally wrong..
Oh, that is something new. Amd how does white noise show up on the scope? How do you vidually evaluate clipping?
Sorry wrong person
Completely incorrect. Not everyone can afford higher volt source units, hence why there is input sensitivity setting for matching. Please spread correct information and not just your own opinion on things.
Can you please specify what exactly is incorrect? Talking about higher voltage source it is my advice and opinion. I am not stating any facts that can be incorrect🤷 I'm confused...
Again you are so helpful thank you for all that u do I learn more and more every video u put out 🤩🫵
