How do you set gain on an amp?

Question

What exactly is gain, I have 3 amps and none of them have gain knobs or switches. I think its pretty important because whenever poeple talk about why subs got blown, they usually also talk about improper gain settings so I think its probably important. How do I set gain?

Answer 1

The purpose of the gain is to match the signal volts RMS to the amplifier inputs, nothing else.

Here is a guide that will help determine power wire
size, correct gain settings and whether or not you
need an alternator upgrade:

You'll need Microsoft Excel, a multi-meter (AC volt
meter) and a way to burn an audio CD from an MP3.

If you don't have Excel, let me know and I'll send you
the required info in an E-mail. [e-mail]

Answer 2

I not sure what you have.
Gain is just how the Amplifier take the Input from your Stereo and Amplify it or increase the output to the speakers. I not sure how to explain; say an Amplifier have a gain of 2, this like your stereo in is 10 Amps then the Amplifier out is 20 Amps. This an example, but, that what gain do. If, your amplifiers not have little knobs to adjust the gain, then it is linear with the input and adjust automatic. You would need to know the specs on the Stereo, Amps and Speakers to know how the gain will work as you turn up the volume.
I wish I could explain better. The link may help more than what I have said.

OK, I thought a little. What you may need is a Pre-Amp that have the Gain controls so you can fine tune that output into your linear amps. Also, look at your Amps. The gain controls may be a recessed screw with a possible cap to hide. This prevent people from messing with your adjustments once they set. This about all I can say.

Answer 3

whilst environment profits, don't use song. Get a disk that has scan tones. Use an eighty hz scan tone to set profits. Music fluctuates an excessive amount of to supply you a consistent studying. If you continue to are not able to get in your forty volt studying, both your head unit does no longer have sufficient line out voltage, or you've got a nasty rca cable, or whatever no longer adjusted proper on head unit. additionally, you did not point out in the event you have been utilising a line stage output converter, as this would even be the main issue because of unhealthy wiring, or only a low-cost converter. you sound like you realize what you're doing however I nonetheless need to ask an visible query.... you DO have meter set for AC voltage? (Just asking) the opposite two solutions that you've acquired also are proper, simply desired so as to add a little bit extra understanding. Hopefully this will likely get you at the proper monitor.

Answer 4

setting your gain is easy for your sub amp, shutoff all bass enhancement, equalizer to zero, then put your headunit volume to 3/4 of max, go to ur trunk then slowly increase ur gain til u hear distortion then back it off just a smidge, done.
same procedure for the door speaker amp...this is usually done by installers to protect the amp/subs/speakers from getting blown by customers who crank it up too much (usually u dont need to crank up the bass boost in your amp in a properly set up system)

Answer 5

Gain is how much output you want your amps to put though your speaker. Basically how loud you want certain frequency to come out. You must have gain knobs on your amp. It must be hidden by something. I had a couple of Zapco amps before and they were hidden behind their name plate in the middle of the amp. Just open the screws to what you think might be extra for looks.

Answer 6

An amp must have a gain control unless it has some sort of feed back built in.
You should check the manufacturer and model.
If it has no gain control it must have a built in output limiter.

Answer 7

turn the gain to about a 1/4 of the way then turn up the woofer control in the head unit. good luck!!!!!!
