No one ever shows the set up part in these videos, Hard to check for distortion if you don’t know how to properly connect the SMD.

so informative and clearly demonstrated, great job as always guys thank you!!!

Great videos btw. I have learned a lot from them. I already have a DD1 and just purchased a Pioneer AVH-X4800BS and can't wait to install. I have been watching your videos regarding that headunit and like what I see.

This video helped out a lot! Thanks

Ok, cool. Thanks for the video!

Got an idea...make a video showing the achievement of finding out max volumes of hu's with DD1...THEN, show the adjustments of eq'ing and adjusting the music. NO one does this and people ask the same friggin' question: "Do I have to listen to my music with flat settings and no adjustments?"

Thank you very helpful.

What level do you have the subwoofer control on the pioneer head units when testing

great vid but you forgot to show where to connect the smd in the back of the head unit

I have seen examples of people updating firmware to gain extra features but is it possible to add a max volume setting via firmware? So that people can't accidentally turn your headunit up into clipping. Also do you have a record of head units that do not distort over rca? And the max voltage of each.

Question, aren't we suppose to first make sure that the treble, bass and equalization is first set to flat? DSP settings off? Last question; if I'm not mistaken when you check the head unit with the SMD tracks wouldn't it be the first 2 tracks and not track 6 which is with overlap? Not picking just trying to understand the difference. Thanks for all the that you guys do for this industry. Keep it up!

I have a question on this. What is volume on the phone? because that can distort or clip too.

I have a Audio Control 6xs,using the dd1,should I turn up or down the knobs on the 6xs when checking the output on the 6xs,I also picked up the CC1.

how do you use the dd1 with a lc7i and stock HU?

It may be more accurate if you turn it off of Powerful mode (4:01) before measuring clipping.

what was the settings for CD and USB i didnt see either of those on the test? awesome vid by the way ive always been curious about this ive got the 5800bhs in my Tahoe and love it thanks for the vids

I understand in this instructional video you use an aftermarket Pioneer. If I use a Toyota factory navigation head unit that is stepped down with a Rockford Fosgate DSR1 do I start at the DSR1 since that is where the RCA's begin in the chain? Or do I need to uninstall the DSR1 and use the factory speaker output leads to set the max volume level for the head unit first then move to the DSR1, reinstall it and set the max volume for the DSR1 in the chain and then finally the amps? I set my clipping fur my amps but neglected to accurately set clipping fur the factory head unit or the DSR1.

can you set these stereos to like the cars volume adjuster or do you have to use the one on the stereo.

Could I use these numbers on my pioneer head unit. Or should I invest in a dd-1

Did you guys use subwoofer rca for 40hz or same f/r rca ?

Cool. I have this exact same HU. So you guys just saved me the money and now I know 38 is the volume limit. I wouldn't buy jack that puts money into the hands of that dousche.

so how do we know if our phones are not clipping when sending the test tones through our phone ? and how do you use this tool if you have a pioneer unit with no cd drive?

Nice video . So I’m guessing everything else was set to flat . Also when setting gain on a amp is a good idea to use the source level adjuster or set it to 0 ?

Can use and oscilloscope to adjust source level controls or do you have to use the SMD dd1 only ?

Nice video I have a pionner dj-s51bt do you know the point volume? Thanks

Thanks.

Instead of a dd1 and a CD can I use a hz generator app and an oscilloscope?

What I'm still confused about is When I hook up my phone to my AVHX my phone volume controls the Loudness too so if I have everything set just right then I want to play a song through my Phone it might be blasted So I have to then adjust it through the phone Volume . Is there any other way to make the radio control the Volume only?

What about the speaker and subwoofer +10 db? Or leave it at 0?

What about the EQ, does the EQ settings affect any of this? I noticed you have it on powerful and not flat. Or is that just for the speaker out puts?

I have the new 601ex and maxed out my speaker and sub speaker level control to 10 on all .. have a 4 channel amp and sub amp hope im not sending a clipped signal

Hello guys at 5* car audio. Great video as usual, but I have a question. I have a pioneer ave-x2800bs and when using the pre-out from deck to DD-1 I get distortion at volume 12 and it does not trigger the 40hz or 1k signal light. If I go to the -dB tracks it will increase the max volume by 1 each -dB level that I change too. The only track that seems to work is the -15db track which I believe is track 8 and it’s signal light comes on around volume 32 and the distort light comes on at volume 39 of 40. My head unit has 3 sets of 4v preouts so I’m confused why it doesn’t seem to be functioning properly. Oh and my eq is flat and crossovers are off on deck. Any idea what may be wrong, or is this normal? Thanks in advance.

How do you get your phone to play the different hertz for the different source tests?

Great Video! Would the DVD source level be equivalent to CD as cleanest sound and with regards to the pandora app on the AVH are you able to change source level also?

I watching this video right now can u do this on the 8 prs

how do i set my bass knob on the pioneer gm-9601d using the smd dd 1

Hey, love the videos!!! I was wondering, I have a Pioneer DEH-80PRS and a 4-ch amp hooked up and would like to run some tweets off of the reciever as well. How can I compensate for the distortion/volume difference between the reciever amp's max clean level and the 4-ch max clean level? Can I check the reciever amp's max clean power with my DD1 and then adjust my outboard amp's gains until they're adjusted to match the reciever's volume? I want them to both be getting their full potential

Wouldn't it be better to use a db meter and the sla to adjust the sources so they are all at the same volume? Then go back and check each source to find out where the clipping occurs on each one. It seems like your end result would be a better balance when switching between sources but still know the maximum volume before clipping.

Is it ok to add source level when using a DSP

I had a question if I keep the source level in the middle does that mean I turn my apps up higher on the game and if I turn the service level up higher I don't have to turn the amps gain up as much is that how it works

@Five Star Car Stereo. I have a HPS140i oscilloscope and I also have a voltmeter. Would it be easier for me to use the oscilloscope to measure the max volume output on my Pioneer SPHDA120 and move onto setting the gains on both my amps? Or can I just do the old fashioned way of OHMS law and using the voltmeter at the amplifier. I'm sure these were reliable ways of doing it before the SMD DD1 came out? Also setting the crossovers, if I don't have the tools for setting the crossovers, is there a formula used so that the dials on the amp match with the crossover point you are setting?

If i am running an amplifier is there still a max volume for the head unit? Im asking because my door speakers are clipping bad and my amp doesnt seem to be clipping. So it appears to be in the head unit. I have the Pioneer 10.1” and I cant hardly get over 16 on the volume. I think max volume is 38 so Im stressing. Hopefully I dont have to buy a new head unit. This one was $1600

Can the DD-1 plus be used with a equalizer and DSP connected?

Can this same thing be done without an o-scope? If so, how do you complete this task?

Hey Dean, out of mere curiosity what about Pandora and Spotify? Or do the levels for those 2 just fall under Bluetooth since they're both a BT connection?

So after setting max clipping volume and SLA settings...do you adjust the amp gains (mono sub amp and mids and highs amp) using only the cd or do you have to adjust gains using all the sources or will the cd cover the gains in general to prevent clipping???

Hello I have a quick question I have a double din pioneer stereo when I connect to play I have a problem with the volume when I put volume up it come down by it self ???? Do you guys now anything about that ..

Hi I managed to browed one for a day now I can do bluetooth & usb not aux cause my phone doesn't have that jack anymore so I want to ask for the USB to get to tone I have to get it onto a USB to test is that how it works because I have it on my note 10 plus?p.s what about the subwoofer level where to set that at please reply greatly appreciated

Do jvc and kenwood head units have a Source Level Adjustment?

mine turns off or cuts off at (Pioneer AVH-1440NEX) Volume between 27 and 29 depending on the music is playing. Will this video fix the problem?

Hey there guys is there a way to detect clipping with a multimeter or oscilloscope?

Can you do one for the Pioneer AVH-X4750DVD?

so if you are using a mono amp and a 4 chan amp, you would first set the decks sources like u have in the video and then , with use of dd1, set the gains on both amps? OR should all sources be kept flat at 0 and then only the dd1 should be used to set the gains on the 2 amps?

Great video! Would these source levels apply to a AVH-4200NEX?

A/V input is probably the lowest and weakest source out of the bunch while bluetooth is probably the loudest. I jumped right to 38 and adjusted my amp gains after while keeping the source adjustment at 0 (started with bluetooth). What I seen was when I later went to adjust my weakest source, even at the highest source adjuster/volume, it didnt seem like I was getting my most potential, like it could SAFELY go louder if the volume had more increases.. Might sound backwards but I feel like starting your adjustments with the weakest signal may be best, definitely dont want to start with the loudest source (unless your only goal is to not blow speakers). You stand a chance of the strongest source getting to a max volume prior to radio's clipping max (distortion by 30 instead of 39) but atleast all the sources have a chance to reach max potential.

Hi, I have pioneer avhx4700bs. Im using a audison bit one processor, should I adjust the source level before or after when setting the processor?

so do you recommend maxing out your sources vs having evrything flat before setting gains on amps?

Is this for preamp out or internal amp

How about the volume of the actual source or on the phone?

Good info.. but a guy just need to set up his car ones.. smd is insane pricy.. Any other way to set up a system without SMD?

What app was that you used to play hz out of aux

I have the 3600 I was wondering if you have performed the same test and if the levels matched?

hi question i have the 4200 nex but dont have an amp for the mids n highs. i just have an amp for the box. i have the speakers hooked up to the radio itself. how do i hook up the dd1 to test the head unit

If we keep vol upto 30 thn cn we keep source level to full(4)?

How to set the remote bass knob using the smd dd1

Did you hook up the dd-1 to the RCA output from the head unit? And can you use the dd-1 to detect distortion from the head unit if you are using the head unit for the interior speakers? Or is the DD-1 only good for RCA inputs from head unit amp output RCA's?

Hey guys can you help please? I have 2005 Pontiac G6. Radio play normal on AM and CD but FM has very low volume. Why? How can I fix this?

Was your phone volume level at max when checking the AUX and Bluetooth distortion?

Hey guys I’m trying to tune my system with the dd1+ and cc1 and I found the max clean output volume of my head unit and I’m trying to set the gains but I can’t handle the sound of the test tones. I have my subwoofers unplugged but I don’t know how to stop my midrange speakers( 2 6 1/2’s 2 4x10’s and 2 4x6’s so it’s realllllllly loud) from playing. Can anyone give my some input on what to do.

hi.maybe you checked Pioneer SPH-DA120 clipping point????

What app are you using on your iPhone to display the frequencies?

So why not max out the. Volume setting (40) then reducing the source volume level until not clipping or distortion is detected. That way no one ever turns it up to far and destroys speakers 🔊

Can you guys test a MVH-1400NEX for me? Need to get an idea of where my volume should be since I don't have a DD1 or O-scope...

how do u set ur gains using the dd 1 i'm using the avh-x4800bs prime r600.4d jl audio twk-88 dsp prime r1200.1d

Wats a gd radio 2 get for my dodge grandcaravan it's a 04

Pioneer amps usually clip at 45 or 50

So got a jvc radio i put it in a 95 geo metro im running 4 pironeer speekers and i got an amp i ran the speekers off the amp and i have to almost max the radio out to get it to out put louder sound i got the gains set with o scope volt meter so i know the speekers are under powerd so i got a bigger amp and running all 4 speekers at there 50 watt rms rating it made no difference on sound output just hade more bass the deck olny puts out 2 volts on the pre outs on the back sub is same way but on my old deck it was loud on the bass but that deck olny hade 1 volt pre outs so idk maby someone can help

This is a great video. Question: Why doesn't pioneer (or any other companies) just make headunits that provides 0 distortion at any volume any source? Thus the only thing you'd have to meter are the gains on the amp.

What about the eq on the head unit? Do we ever use it. Leave it flat all the time?

Where do you connect the dd1?

Guys I need your help. I had a pioneer gm8601 which puts out 800watts certified @1ohm. I was pushing 2 8's with it at 1 ohm fine. I upgraded to a dual da6001 that puts out 1300watts certified but no matter what I do with the gain it barely has any output compared to my pioneer. I'm using RCA's from the back of my pioneer x65bt radio, ARE CERTAIN AMPS LESS SENSITIVE AND NEED MORE RCA VOLTAGE? Theres NO way I should have my gain almost maxed and still have barely any output?! I have to go on my radio and turn on "loudness" which is a total clip magnet! any idea what could be the reason my old weaker amp has much more output?

The volume of my radio is too low at max. How can i increase the power volume? Tks to you

Can you check the HU for distortion without an amplifier? With the dd-1?

i dont the video u was talking about using somthing call fero for your wire in ur install i cant find that video video please help me

I know with my o scope that a cell phone has its own volume level where clipping is present. I believe my galaxy s10 (usb audio) clips at about 115 out of 140 on the volume adjustment scale. Just an fyi

What level set for cd?

r u using the disk that comes with it then to those different sources how r u really doing it

What is the app you are using on the iPhone to play your frequencies?

Where do you get the test tones on the phone

Did you guys happen to test the SD card source level?

what ppl don't kno is the volume level on their phone.. something u didn't mention.. some turn the phone all the way up and adjust it on the head unit

u say u use the audiocontrol so how will i use the dd 1 my deck is pioneer avh-x4800bs rockford fostgate prime r600.4d and r1200.1d to set my gains

WHICH DSP DO U USE AND WILL IT WORK WITH THE DD 1

What if you don't have a cd drive? I copied track files over to flash drive and they're not recognized.

How do u find max volume without a Dd-1

Hello following happens , I have a ford f150 extended cab a JL amp, bass JL 12 inches, a pioneer amplier 4 channels, 4 speakers pioneer 6x8 all connected to a avh x4700 , it does not sound good

The distortion lights turns on before I even get a signal

I can't find this SMD dd1 anywhere everywhere I go to it's out it's not available they don't have any in stock what's going on here

Most pioneer distort at 38

Just max the vol(40) for all of the sources and increase/decrease SLA accordingly. Theres no point in finding where the volume clips if you can just decrease SLA. Its an unessasary step.
