Can someone please tell me is it possible to connect a lead from the back of my Denon 3803 ( trigger out 12v ) to the remote in on the A90. I know this is how the P90 is connected to the A90, but then i dont think the P90 needs any RC5 codes. Are the RC5 codes just different voltages and the 12v code would just switch it on....??? Also......if it is possible, what type of lead would i need....?? Would it be a 3.5 to 3.5 mono, or stereo.....??? It does not seem to say in the A90 manual, or give any kind of wiring diagram. cheers.....chris.
