_paralyzed_ Posted August 12, 2016 Report Share Posted August 12, 2016 What channel are you testing, left or right? I swear I've read that certain alpines had to have the opposite channel of what it said in the manual to get the dd-1 to work. Try the other channel, and reversing polarities on the other channel.

It's an NVX not an alpine but it may be the same board I guess. It's a mono block. It only has one channel. Two inputs but one channel.

_paralyzed_ Posted August 13, 2016 Report Share Posted August 13, 2016 Brain fart. Now that I remember more that was for testing head units anyway, and I knew you were speaking of a mono, I don't know why that part didn't click before I typed that out. D'oh!

05accord6spd Posted August 13, 2016 Author Report Share Posted August 13, 2016 So nvx says there is a problem with dd1 and Tony says there is not. Soooooo let's get nvx or tony to validate there claims Quote Link to comment Share on other sites More sharing options...
TonyD'Amore Posted August 16, 2016 Report Share Posted August 16, 2016 All amplifiers should work on the DD-1. The blink while turning up the gain is caused by the DD-1's auto-range circuit shifting gears into the next range. The fact that the distortion LED doesn't illuminate even when the amplifier's gain control is all the way up would indicate the amplifier doesn't have enough gain designed into it. Amplifiers for automotive use should be able to reach clipping with 200mV of input and the gain control maxed. Tony 3 Quote Link to comment Share on other sites More sharing options...
TonyD'Amore Posted August 16, 2016 Report Share Posted August 16, 2016 If you can get 1.8V out of the RCAs with Track 1, how many Volts do you get out of the speaker terminals with 1.8V going into amplifier with gain at minimum? How many at Maximum gain? I'm guessing that the amplifier doesn't have enough gain designed into it. But with those measurements made we will know for sure. Tony I havent seen this dyno on this board, but if they did a cert run, it looks for >1.0% distortion . Meaning, the dd1 software worked. Again, i havent seen this dyno test on this board. If they did a un cert run, it looks for clipping. Meaning again, the dd1 software did its job. IMHO, ...Your "people" you are "speaking with", are doing it wrong. Definitely not user error. I swap out the JAD1200.1D for my old hifonics amp and follow the same procedure (instructions that came with the dd1) and it works, distortion light shows up. With the JAD the distortion light never lights up. Guess I would have to make a video of it. RCA voltage is 1.8v at max clean volume. I can get it to distort while finding the hu max clean volume through the RCAs just not after I hook into the JAD1200.1D. 2 Quote Link to comment Share on other sites More sharing options...
3vil Posted August 16, 2016 Report Share Posted August 16, 2016 And there you go from the man himself. There is nothing special about the board in those NVX amps. Quote Link to comment Share on other sites More sharing options...
Kyblack76 Posted August 16, 2016 Report Share Posted August 16, 2016 Thanks TD. I know your busy. Sorry to bug bro. Thanks again. 2 Quote SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...

I'll also post a video here soon also of doing it per instructions. Quote Link to comment Share on other sites More sharing options...
