well I havent been on the forums for a few days (it feels like weeks) because I couldnt stand the "somethings still not right" feeling in the van, come to find out I've most likely been 1 amplifier down (therefore 1 sub down) since July of last year when i get metered.
It was great to come back to that FOH
Even if I am the William Hung of the audio world
I'll crawl under there with the DMM and hook the leads right in with the speaker wire. Ive had plenty of practice with it over the last week, I kept gain matching my amps in the van- hook up some lights to some extention cords, throw them and the DMM through the port, stick an LED flashlight in my mouth, and crawl in. Disconnect all 4 subs, lay the wires in safe locations, measure amp 1 voltage, amp 2, 3, and 4.... adjust the gains on the lowest/highest, remeasure, cycle repeat.
Ah wait a sec, thats to measure voltage out on the amps... so I need to measure voltage on the outlets whilst blasting pure test tones...gulp. Where do I tap in at? Can I pull a plug on one part way out so it still makes contact so I can slip the pins in to touch them?
