Or you can use something like a Harmony remote. On my remote you press Ayre to turn on the Ayre disc player and the Parasound JC 2 BP preamp in stereo mode; you press DirecTV to turn on the projector, the HD DVR, the Bryston SP3 processor, and the JC 2 BP in pass-through mode so front LR from the SP3 can access the pair of JC 1 amps used for stereo. (The other channels from the SP3 go directly to amps and a bass manager.) You download an ap from Logitech that lets you set what gets turned on when you press each button. Pressing a single button turns everything off.
