refresh my memory about polarity switches--does one need just ONE gizmo??? (i.e. between preamp and amp). Or a pair of gizmos (i.e. left and right).
And is there a benefit to putting gizmos on the source components rather than just at the amp??
Yo, To', You need only one pair in any system; left and right channel. As for where to put them, I have two thoughts; if you know the recording is inverted and you know your system doesn't ultimately invert polarity, I suggest putting them as far ahead of the source as you can in your system. If you're not sure of the recording but you know what gear in your system inverts polarity, put them there. This is assuming you have only one piece that inverts. If you have two units that invert, I suggest using it in the unit furthest up from the source in the system chain.
Doesn't some GEAR invert polarity??? In that case, even if the mastering was done perfectly, there would still be a need for a polarity switch (or another inverting piece of gear).
This is correct Tonto. Here's the way it works; aside from whatever the recording is, if you have an odd
number of gear that is a different polarity form the rest of the gear in your system, i.e. 1, 3, etc. the polarity is inverted either positive going or negative going in relationship to the rest of your gear. If you have even
number of gear that inverts, the music signal will be the same polarity throughout the system, either positive or negative.
(Did I get that right Robert?)
Yep! You da man! Thanks for saying that simplier (simplyer, sermplier smilpyer) than I could.
Josh, here's another useful method for testing polarity I used to use all the time...
Stand facing your system and play your music. Listen. Then play the same music again but this time stand with your back towards the system. Now you're hearing it opposite. Determine which sounds better. If it sounds better with your back facing the system, simply move your system to the opposite end of the room. As Infinity suggested about different cuts on the same CD, you can do this for every song on a CD. Helps if you have a buddy to help and while this method is a little more time and requires a little more effort, it's free!
