I'm in the process of getting a new (used) pre amp (2 channel) and I am wondering if I can connect it to my receiver (using the receivers power amps) until I can afford the amp in a few weeks/months. My manual says that the receiver can be hooked to an external decoder... Does that mean an external pre amp or just a decoder? if I hook my pre to the main inputs on the receiver do you think it will bypass my receivers volume control? Here is my Receiver Manual the connection diagram is on page 14 of the manual. Any help would be greatly appreciated! Thanks!
