Correct Way to Invert Phase

Before reversing the positive and negative connections to your speakers, check your power amp and sources if the phase/polarity inverted !

I use the Isotek Ultimate system set up Disc. This will within 5 minutes demonstrate the sound of your system inphase and out of phase. When i put this Disc on to fine tune my system inphase gives a solid focused vocal image central in between speakers tightly in focus, out of phase the vocal comes from between your speakers but with no fixed position. Apparently the better the out of phase sounds (vocal with no fixed position) the better your system will sound when playing CD’s.

>>>>>The out-of-phase track will sound correct as long as the system is in phase (correct polarity). Also, the real function and advantage of the out-of-phase track is to allow accurate positioning of speakers, such that when the sound is MOST diffuse (least focused) with the out-of-phase track - the sound is coming at you from no particular direction, even from way off to left and right 🔛 and behind you if you’re lucky - the sound will be the MOST focused 👀when the system is playing a CD that is in correct phase/polarity. It should be pointed out that it takes a lot of work to get the out-of-phase track to sound totally diffuse, a LOT of leg work 🏃🏻‍♂️ in the room treatment department and moving around of speakers. Rome 🏛wasn’t built in a day. 🤡

According to this thread 92% of all CDs play with inverted polarity (I heard similar stats before).

@delcal  This has been debunked. The correct number is 'about 50%'.
