Got a new amp ts 1.3kw (nothing else has changed) dd1 works fine. I'd send mine in its collecting dust

I've tried Track 1 (40Hz 0db) Track 3 (40Hz -5db) and Track 5 (40Hz -10db). Wow if it won't clip with the 0dB track then it must have a anti-clipping circuit in it or some type of rollback circuit so that it can't be pushed too hard. I personally have not seen or played with one of these amps in person though I know that it is VERY similar to a model in the Hertz lineup and we have heard of people having trouble with that one as well. If the amplifier is not allowed to clip one may consider that an amplifier problem, not a DD-1 problem. The DD-1 is doing what it is supposed to do, alert the user of distortion over 1%. If the amp isn't capable of clipping it not work on the DD-1 or DD-1+. If you want to set it with a voltmeter like someone mentioned, you can do it, but you must use one of the overlap tracks. Simply using a 0dB sine and setting with a voltmeter or scope will result in ZERO gain overlap. As a side note for you number chasers, a 1000 watt amp that is allowed to clip will be significantly louder on the meter than a 1000 watt amp that is not capable of clipping. Based on the information you have presented to me here, and not playing with the amp in person, I'd say this amp has a rollback circuit of some type that doesn't allow for clipping. Tony Thanks again bro. I hate/love to text you. But hate bugging you. I know how busy you are. I appreciate you throwing your knowledge around. Maybe the OP can send you the board, and you can sniff around some. For funnies. Hell, I may pick up the shipping both ways just for kicks. Thanks again man. Thanks for always responding to me. For real. I'm just glad that I got to the bottom of it and that Tony, someone I know knows what he's talking about, put the nail in the coffin. I'd be willing to send mine to Tony. Plan on getting another amp anyways.

They are good man. Lots of people use them.

I've tried Track 1 (40Hz 0db) Track 3 (40Hz -5db) and Track 5 (40Hz -10db).

Yes and get that twisted sounds !!!!!!! before i snatch it from you !!!!

The amps gain goes from 6v to 200mv

I follow this video. Have watched it 100 times lol. https://youtu.be/9h53-w4PAKQ?list=PLNMbsRIxVU1KMDzeKrXVV3gAqwVVX0kMn

I'll post a video tomorrow. It's to dark out right now.

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. Alright playing Track 1 off the CD, I get 1.837v directly on the RCAs. Coming out of the speaker outputs 9.93v with gain at minimum LPF at max (320Hz) SSF at lowest (20Hz). Max gain I get around 50v. One thing I did notice though, when I was up closer to max gain the voltage would fluctuate drastically. It really wasn't a solid voltage after I got past 39.9V. It would bounce all over the place. 60v, 40v, heck even up to like 65v playing track 1. Go back to the RCAs and they read 1.837v without fluctuating.

I'll also post a video here soon also of doing it per instructions.

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.

I don't have any problems with heat.

well currently I have my gain set by a dmm to 34.64v. That voltage should be 1200watts @ 1ohm

Any chance he could do a video on the newest version being as though NVX informed both the OP and me that the internals have been changed?

Have the SSF at 20hz which is all the way down and the LPF set to 320 I believe or whatever the maximum frequency is. I get the Signal light and the 40hz light.
