Nate197 Posted August 10, 2009 Report Posted August 10, 2009 Can someone explain exactly how a phase shift works (0-180 degrees) on an amplifier? I have heard some things about when you invert subs but, I am not sure exactly how it works or what the proper degree setting should be. Quote

E a r t h Posted August 10, 2009 Report Posted August 10, 2009 it reverses polarity ex. cone moves out & in vs cone moves in & out with reference signal applied Quote

E a r t h Posted August 10, 2009 Report Posted August 10, 2009 zero,... if you wired up all your speakers + and - terminals properly from + and - amp outputs, there should be no problem all the phase does is let you change polarity in stead of reversing the wires on the amps or inside the box manualy like we used to before that nifty knob was bestowed upon us Quote

I can't think any reason to have it at 27, or 42, or 103 or anything in the middle...

zfrerichs Posted August 10, 2009 Report Posted August 10, 2009 i think it is also used as a time delay Quote Roseville, CA
DHFHades Posted August 10, 2009 Report Posted August 10, 2009 i think it is also used as a time delay oh, I was thinking there may have been some SQ purpose but wasn't really sure Quote 1990 Jeep Cherokee 4X4 Pioneer DEH-P2900MP, Big 3 done in 1/0, 1 run 1/0 ran to amp DAT HF1000.1 #007 powering a DC lvl4 15 DAT HR 4085 prototype powering 2 Selenium 6s and 2 no name tweeters running active 1st place in AS3 @ Surf City Sound Off, 140.8 @ 45hz @ the headrest. rebuild coming soon to get a better score "I regard the brain as a computer which will stop working when its components fail.

E a r t h Posted August 10, 2009 Report Posted August 10, 2009 then why is it a knob and not a switch? I can't think any reason to have it at 27, or 42, or 103 or anything in the middle... good question,...my guess is to match the asthetics of the end plate also shouldnt be any inbetween, seems like there is just a spot where it changes. i never mess with mine, i leave it. i still do it the old school way by checking wires and switching them. im kinda anal about wires matching with same poles and whatnot Quote
