James,
Can the RCA and Balanced inputs on the back of the SST amps be simultaneously or both plugged with two different sources and then toggled on the back with the selector switch. In other words can a home theater receiver be plugged into the rca's and a preamp be plugged in to the xlr's and then via the selector switch on the back of the SST, you can select which sources (preamp or HT receiver), you want to use?
Thanks,
Bill
