Sushi, thanks for the Crutchfield link, it was very interesting...

I'm setting up my first whole-house audio from one receiver. I purchased a speaker selector and was planning to hook it up to the "B" speaker outputs to power the speakers on various rooms, and keep the "A" speaker output for the home theater speakers.

I'm assuming this can be done as long as I don't select the "AB" speaker output, am I correct on this? Is there normally a difference between the A & B outputs?

Thanks!
