Dual Mono?

.......I would just add that a regular "stereo amp" typically has a single power supply that provides power to (usually) two channels. The two channels also share some circuitry. Craig

I love simple answers. Thanks guys

Garfish is correct except for the idea of one power cord, some (not most, but some) use two power cords to completely sperated the two discrete amplifiers. So in this case the only tihng the TWO amps share is a chasis. I believe one manufacure actually advetises that you can cut the amp in half with a torch and it will still work, if you do not believe me check out www.balanced.com and check out the VK-500 and you will find this to be true.

Same is true of the Lab 47 Gaincard , either the 25WPC or 50 WPC version. The Amp module is seperate from the Power Supply module and when two (2) power supplies are used , each powers one channel and has it's own power cord. The beauty of these amps is you can start with one (1) shared power supply and later can add a second power supply for true Dual Mono.
