Volume Control for second set of speakers

For your consideration:

A perfect application for the TVC-1 is adjusting the volume of
remotely located speakers. The TVC-1 adjusts the volume of
speakers connected to it by attenuating the amplifier signal.
Niles volume controls use autoformers instead of L-pads for
the volume controlling element. This assures minimal internal
power dissipation with virtually no power wasted as heat.

@pratorious yes that is perfect thank you and what I was looking for!

And this will not degrade the signal?  

Also my speaker wire is 10AWG - this accepts maximum of 14AWG - could I use speaker pin connectors?

Now where's Audiogon's reigning theoretical physicist when you need him? Oh well. Guess we can always use the old search engine...
because... as with everything else.... its been asked and answered:

So you can either slap a rheostat in series with the one you want to trim, or (much better) open the amp up and add them inside following the circuit diagram.

Whew, easier than I thought. Thank God, no Morphic Fields involved....
