Dear Eagleflyerfan:
Twenty seconds ago, I was utterly unfamiliar with your amplifier -- and judging from their responses, so are Mssrs. Rmwear, Tom6897, and Mceljo.
However, twenty seconds is all it took for me to go from this AudiogoN page, to Google, and to this picture:

Your amps each have a single input. You do have two input connection OPTIONS (single ended or balanced) which is a nice feature.
Your amps each have TWO sets of speaker outputs, and an Output Selector Switch. This allows you to hook up two speakers to each amp; and the Output Selector Switch allows you to play either speaker by itself, or both speakers at the same time.
