Home theater bypass


Hi I am am new member I need some help with routing for my home theatre. I have a Onkyo 7.2 receiver and a mac275 amp with a cj pre amp. My speakers are Maggie's which I use for both systems I'm plugging and unplugging every time I want to use one or the other. How can I wire up a permanent setup to avoid this. Any suggestions would be great!

So now I am about to set up my new 205 which has a trigger to put the C48 in bypass, but what if I just want to play a CD and not HT, how do i control that, if every time I turn on the 205, the C48 goes into bypass.

Connect the RDL input to center channel or LFE output of 205, connect the RDL relay switch between 205 trigger output and C48 trigger input.
The HT bypass will be done automatically.
@audiomaze -- what input on the CJ are the audio outs from the DVD player connected to?
the DVD player is connected to the receiver with a hdmi and connected via the audio outs to the preamp inputs. The receiver preouts are connected to the preamps tuner inputs. The preamp is connected to the Mac then the speakers Maggie 1.7.
