How to set amplifier gain? (1 Viewer)

[Scott L]

I have it very low, because I read somewhere it's best to have a good strong signal from the head unit rather than just amplifying a weak signal via the amp gain.

So what's yours set at.. low/medium/high? Any rule of thumb on setting it?

Depnds totally on the amp and head unit being used. What equipment are you speaking of?

Just a basic system. Alpine 9813 > RF 551X > Focal Polyglass Components & Coax's. About 70wx4. thanks

A general rule of thumb is to turn the amp gain all the way down, turn your HU volume to about 3/4, then slowly turn your amp gain up until you hear clipping or distortion, then back the amp gain down just a tad.

Second option, check your specs on the HU to see how many volt output it has and set the amp accordingly.

Rule of thumb....set it to what sounds best.

Ask any installer and 9/10 times they set it by ear.

Unless you are competing, then they only thing that matters is how it sounds to you.

How convienient, this was my next thread. Do any of you know where I can get a simply 1khz unclipped with no attenuation as a singly track??? I saw Sean's link and it looks like I can use Track#6 on CD#2, however, I am on dialup and I'm not downloading 148MBs of data on dialup! I was wondering if anybody has a link to a simply 10 second track consisting of the above spec. I have an AC voltmeter already so all I need is the test tone...

Go to:

PDF file below:

http://totoro.efiregate.net/HTMLPage...20for%20CD.pdf

Goto page 2, take a look at the track listings for CD#2. I want track#6, I don't want any other tracks, I don't need to hear what clipping sounds like and I don't need to make this into a PhD dissertation! I just want a test tone!

Don't need it anytime soon, if I can't find one elsewhere, I'll wait til I'm back to work and download it there.
