Hi John,

The best way to do this is with four channels of amplification and doing the switching at line level. It makes for easy level matching by having volume controls on the switcher.

We built a high level switcher to be able to A/B different components on the crossover. This takes a lot of big relays and needs to also switch a volume control for each the A and B back at the line level input. I am thinking the four channels of amplification is the easiest.
