RooTxBeeR Posted October 26, 2013 Report Share Posted October 26, 2013 I went to use the DD-1 on a friends car with really bad results. No matter what I did, checking the HU for clipping, and the amp, always had distortion on. No matter the gain setting, nor the volume. The vehicle is a Acura TL with stock stereo and navi, with a LOC going to a Addictive Audio 100.1D. I first tried to use the DD-1 to get a clipping limit on the HU, which the instant the probe hit the pos terminal, it got distortion. I even tried to "set" the gains, without setting them, just to see if the light would come on the same as it did before. Sure enough, on the 0DB test tone the instant the prob touched I got distortion. It was weird though, when I used the -5 tone, the distortion light came on again, but not as strong. And then with the -10, the light didn't even come on at all. And the light came on how I said it did per tone, no matter the gain setting or the volume on the HU. The signal and 40hz detect would come on how it normally does, but the distortion was always constant. Anyone got any info here? Feel kind of shitty because I reset this guys gains and ended up not coming through with my tool. I set his amp the old way with a DMM, backing off the rating it said it was supposed to be at to be safe and he said it was much quiter than what it used to be. Would like to get his amp set right and have a happy friend lol Quote On 11/20/2012 at 8:54 PM, AMI CUSTOMS said: Turned mine up today at a light, guy next to me his steering wheel started moving and he looked over at me like I was a magician lol.

CleanSierra Posted October 26, 2013 Report Share Posted October 26, 2013 I wonder if his LOC is bad? Quote Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...

RooTxBeeR Posted October 26, 2013 Author Report Share Posted October 26, 2013 Check amp settings as well as make sure Xovers are set to THROUGH. They where only variable, I had the SSF set to as low as can go, and the HP to as high as it could go. He actually had the variable bass boost on, I am guessing that's why it sounded louder. I turned it off lol. He did mention he thinks the LOC is off of the 6x9 on the rear deck, but there is no crossovers built into the speakers, or in the HU, that wouldn't effect anything right with the signal?

bbeljefe Posted October 26, 2013 Report Share Posted October 26, 2013 The battery in your DD-1 is ~10 low. That's not good. Get a hot battery in it and try again. Make sure his bass and treble are flat and that there is no loudness feature turned on at the head unit. And what you described with the different tracks is correct function. The DD-1 detects distortion on the zero dB track before the -5 dB and on the -5 before the -10, etc. Basically, you have the option of setting the amp at zero distortion or, with the down dB tracks, up to 10% distortion (iirc). And he obviou trade off to introducing distortion is SPL. And if you get the same results with a hot battery in the DD-1, recommend that he buy a good quality LOC.

audiofanaticz Posted October 26, 2013 Report Share Posted October 26, 2013 (edited) Every LOC I ever tested has been bad or should we say shown distortion and extremely dirty except the prototype HLC-1, so testing it on an amplifier that gets its signal from a LOC is going to show you distortion even before it even picks up a signal. Test the dd-1 on a headunit or amp without a LOC on a system you previously tuned and know it was tuned good, or for that matter, plug a RCA cord into to the DD-1 from any output source just to make sure its not the DD-1. If your sure the DD-1 is the issue after bench testing it on another item you will need to contact Tony to get it repaired.

RooTxBeeR Posted October 26, 2013 Author Report Share Posted October 26, 2013 I can try a new battery, I really have no idea what a good voltage for one is so it's past me. That is really unfortunate what you said about the LOC's. I am sure my DD-1 is not broken, it previously tuned my amps. What I will do is hook up a spare amp and test the DD-1 on it. Just in case that my DD-1 is bad, I don't screw up my gains on my daily amp.
