well i was thinking just use the wall timer to turn on the whole system.
I suppose though that you could just run the signal through it just like you would run power through it. It might be too lossy though, or it might pick up interference because it wouldnt be shielded. wouldnt be too hard to shield it though. give it a try :lol:
of course you could do it other more professional ways, but this is very nice and simple.
