Phase switch on pre amp use?


My KCT pre amp has a "Phase" switch that baffles me. There is one on the unit itself and one on the remote. What is it used for? I am semi paranoid of myself or the wife accidently hitting the button on the remote while the system is playing. Any reason to be 'noided about this?
Thanks, John

I don't know what "'noided" means but this is no big deal to anyone (except perhaps Clark Johnson). It reversed the polarity of both channels and, in most cases, is inaudible. In some cases, there may be a change which you might find better or worse. There is no useful way to know what is correct.

In other words, you can play with it but don't sweat it.

It is fine to play with it and is meant to be experimented with, on Classical sometimes it may be desired....thats my experience, many times you cant really hear a change. In short it is nothing to be scared about.
Where does it reverse the polarity? To the amp, speakers, all around...? What is this supposed to do, change sound or are some systems positive ground?
(Noided is slang for super paranoid)
Thanks again, John
The polarity is switched internally in the preamp. Some amplifier circuits invert the polarity 180 degrees while others do not invert. In an "op-amp", which is an IC chip used in some electronics - it has both an inverting and non-inverting input. There may be a slight improvement in sound by switching the phase. Try a listen both ways.

Another analogy of phase is your speakers. If the left and right speakers are hooked up out of phase, this will make a big difference in the sound. BUT on you preamp phase switch you are inverting BOTH channels at once - like if you switched Positive and negative on BOTH speakers.
