I have an Xtant 3300c in my Camry, and I never bothered to get it set up right. I always had to turn up the volume on my deck too far to get the volume I wanted out of the amp, and my speakers are of reasonable efficiency. Because of that, I'd like to see if adjusting gain settings will help.
The gain jumper for the two front channels is set to the 0 setting. I'm not clear from the installation manual what that means. What is the gain for this model amp when the gain is set to 0?
Also, what's the difference between that gain jumper and the rotary gain pots for the front channel?
Can you folks recommend a procedure for setting gain properly on this amp, both jumper and rotary pot controls?
Thanks

Yes, just did that. I'm getting a stronger sound quality in general, with less noise. So, what is the actual gain now that I've turned this amp
up to +10dB?
What is the official procedure for adjusting the gain control pots?
I'm guessing the jumpers are for the large gain setting and the pots are more refined control to fine tune same?
Thanks

Yes, on the pots.
Don't get too caught up in setting the gains a certain way. You want to be able to get to full power at about 75% of the volume control range, assuming that you're using the RCA outputs on your head unit.

Okay. What is the actual gain now that I have the gain jumper set to +10?
BTW, isn't it a little strange that +10dB is to the left of zero on this amp, and -10dB is to the right of zero. I think that's why I never saw a positive difference before. I'm guessin that in the past, I probably just couldn't see well enough, and moved the jumper to the right, when I should have moved it to the left.
Oh, and while I've got your attention...I've never seen car audio components with balanced outputs. Are there decks with balanced outputs? If not, what other car components have balanced inputs/outputs?

Lots of amps have balanced inputs. It's one solution to prevent ground loops.
I can't think of a reason why the ± gain should be left or right or why it matters.
I don't know what the actual number for the gain is or why it's important. If you want to know. measure the input at the RCAs and the output at the speaker terminals and calculate what it is.
