Setting Gain.

[meade916]

that chart is the specs for the amps, it tells you nothing about when your amp is going to clip. Thats what an O-scope does.....

and when you set gains, setting them to where there is no clipping is the name of the game.

40? whats supposed to be at 40? what are you talking about?

anyhow, it appears to me that the link you showed us is for JL audio amps ONLY, where they already know what voltage each of their particular models clip. Its a mostly useless tutorial without having a JL amp (if im lookin at that right).

You need an oscilloscope, or you will never know when your Soundstream amp is going to clip (the pcx1000 is SS right?). Also, that "turn the deck up to 3/4" is crap too, you need an o-scope so you can get the most out of your deck also - because you need to know for SURE where it clips also.

as far as gains are concerned, i dont see a dmm being of much use UNLESS you are MATCHING gains in a multiple sub-amp setup.

Yes that amp is SS. I found that tutorial on here and then I tried the one that enemyofsilence linked me on that thread

Either way, I don't have an oscope.

DAMN. Steve posted twice on my thread Can I say, DEMO in December PLZ? Anyway, someone is selling an old OSCOPE on craigslist but I don't want to spend that money and use it just once or twice. I wonder if since Home Depot rents tools etc. if they have a Oscope I could rent out.

yeah that chart is more or less used to show what power is present at the given ohm load. (i tried taking that bottom white section out...but it's stuck everywhere lol). it doesnt show what an amp is capable of. nor power after box rise. if you KNOW your amp can produce the power at the given impedance, then imo using the chart is better than blindly turning the gain if you dont have an oscope to use.

It's all so flawed because of the 'unhook all subs' part. Even with a scope. Amps make way more clean voltage when they have no current flowing through them... if you were to do it properly you would connect a 1 ohm dummy load and measure the rail-to-rail DC voltage of your amplifier so you knew where it would clip anyway.

Here's the chart without the white bro.

Is this something stereo shops can do? Do you know of any shops in the 916 who can knock this out?

Isn't Meade from 916 area?

woo hoo! lol. it's more intended as a reference instead of a tuning guide

The majority of us though don't know someone who has an O-scope, let alone know how to use one so we have no choice but to do it by ear.

I don't know where he's from but he lives out here. Edited June 20, 2009 by SQMonte
