dougdrake Posted December 31, 2004 Share Posted December 31, 2004 For reasons too difficult to explain (and which would bore you to death anyway), I need to know if there are any dangers to connecting a pre-amp's output to the Aux Input of a separate Integrated Amp, each with its own volume control. My intent would be to set the volume of the integrated amp to a fixed level (maybe 50%) and leave it there, and use the volume on the pre-amp to control it. Something tells me this wouldn't be a problem, but I've been staring at my diagrams and thinking about it so long I need an outside validation. Thanks! You can quit reading here if you don't care about the reason why . I have an SACD player that I want to feed both my Denon AVR/Acurus amp combo as well as my 2-channel tube amp. That way I can use the tube amp for 2-channel SACD/Redbook CD and the Denon/Acurus for multi-channel. I also have a new Outlaw ICBM that I want to use to process any signal from the SACD to route the bass to my subwoofer. My tube amp does not have a subwoofer input/output, naturally, so I need to connect the sub to my Denon. If I run the entire 6 channels from the ICBM into the Denon, then split the Denon's pre-amp output of the front 2 channels to the tube amp and my Acurus amp, I can use the Denon to feed/control the sub and the tube/Acurus amps and have a single point of volume control. (I use a speaker switch to switch the main speakers between the Acurus amp and the tube amp.) I do not want to connect the sub into the system using speaker level inputs as that would introduce 2 crossover systems into the network - 1 in the ICBM and 1 in the sub. Also, when connected in this way, the Denon passes the SACD signal directly through to its pre-amp outputs without doing any processing other than volume control, so it shouldn't "dirty" the signal too much.

3dzapper Posted December 31, 2004 Share Posted December 31, 2004 The only caviat I would give, yes this happened to me, run the amps pots wide open or the may "burn" out that spot. Not burn as in fire but lose electrical connection. You are going to use the volume pot on the pre anyhow. Rick Quote Link to comment Share on other sites More sharing options...
