Absolute phase vs relative phase aka polarity used loosely :(
Correct Way to Invert Phase
Hi,
My Conrad Johnson preamp is phase inverting.
The CJ manual says to change the phase "...by reversing the positive and negative connections to your speakers (be sure to reverse both channels)..."
Can anyone explain why changing the positive and negative connections between the amp and preamp would not accomplish the same thing?
Just wondering if this could harm the components or is some other science at work here that I do not understand?
Thanks for listening,
Dsper

"polarity" refers to +/- connections (ie: at the speaker or amp). "Phase" refers to the motion of the speaker cones, relative to the recorded signal. Reverse the polarity at either end of the speaker cable and you've reversed the phase, at the cones, 180 Degrees. "Absolute phase" simply means cone motion and recorded signal are the same, in the context of The Wood Effect (compression at microphone = compression at your ear). |
This CD includes tests/tracks that will tell anyone interested, whether they can discern reversed phase, in their room, on their system, with their ears: https://cheskyrecords.bandcamp.com/album/chesky-records-jazz-sampler-audiophile-test-vol-1 That some can’t doesn’t mean others won’t. |
mijostyn With my system I can invert phase on either channel or both at the same time all by remote control from the listening position. With both speakers in phase and switching them together not one of you would be able to tell inverted from not and anyone who thinks they can is______(fill in the blank.)I have no reason to doubt that is true with your system. Are you suggesting it would be true with all systems? |
