The question mainly pertains to Denon receivers, but is probably standard for all receivers with 5.1 channel analog inputs. My question is, will a signal that enters the 5.1 channel inputs also be output at the receiver's preamp outputs? If I connect an external amp to my Denon AVR1801, will I be able to use it in conjunction with the 5.1 analog inputs? (mainly the front left/right) Since these inputs bypass all processing, I'm just wondering if they will appear at the preamp outputs. Thanks for any input.
