I owm a Adcom gfp-750 with processor loop, basically you use 1 set of cables out of the Adcom into your processor and another set out of the processor into the preamp. When you are watching movies you turn on both processor and pramp, engage the proc loop switch so you can hear your main speakers during movie use. You do not use the proc loop for 2-channel, the preamp operates normally,and the processor does not have to be turned on. An advantage of the Adcom as well is a passive/active switch for 2-channel (active boosts the gain by a few db's) Hope this helps!
Processor Loop for 2 channel?
I keep seeing 2-channel preamps (Adcom, McIntosh, etc.)advertising a processor loop for integration with a home theater set-up. My problem is that I don't see how a loop would work. The idea of using a 2-channel preamp would be to have a "better" preamp then the one in a Preamp/processor and route 2 channel music through it instead of the processor but then use the pre/pro when watching movies or other multi-channel music.
I've seen a few preamps advertise a "unity gain" or HT pass-through and this makes sense. I just don't see how a processor loop would work. Can anyone explain this to me?
