k3n12ock Posted June 18, 2009 Report Share Posted June 18, 2009 So I bought an AC Volt meter and I'm going by the JL Audio clipping/sensitivity thing on how to set your amp gains. http://mobile.jlaudio.com/support_pages.php?page_id=143 I went out and bought a cheap AC Volt Meter from Harbor Freight ($2.99) and I want to set mines. First off, I need to download the 50HZ test tone but do I DL the 0db one or regular one? Can someone link me to the right one to DL? Next, can someone tell me what the desired Voltage would be at 2 ohms? Thanks. I have the PCX1000D Quote 05 xB - (2) EVIL 18s - (2) BC3500s - NO WALL Channel 1: http://www.youtube.com/k3n12ock Channel 2: http://www.youtube.com/MrK3n12ock2 Link to comment Share on other sites More sharing options...

k3n12ock Posted June 18, 2009 Author Report Share Posted June 18, 2009 http://www.realmofexcursion.com/downloads.htmPower = ((AC Voltage)^2) / Resistance So I'm figuring you mean 50hz @ 0DB? And I don't understand that whole formula. Based on the specs I posted on the PCX1000D what would I set it to? Sorry guys, I'm a noob at this.

enemyofsilence Posted June 18, 2009 Report Share Posted June 18, 2009 according to the chart i linked you to, it should be 40 output voltage. this is going with 800w @ 2ohms. Quote Team Bass-Hz Link to comment Share on other sites More sharing options...

k3n12ock Posted June 18, 2009 Author Report Share Posted June 18, 2009 Okay so it's suppose to be 40 but this stupid cheap AC meter only shows up to 15.6 so I'm like WTF. Am I setting it wrong or something? I have this one from Harbor Freight. Should I set the knob to the 200 or 750 on AC? I'm only gettin up to 15.6 and all my gains are up now. WTF! Oh yeah, could it be my capacitor that's messing up the reading too?

meade916 Posted June 18, 2009 Report Share Posted June 18, 2009 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.
