I recently upgraded to separates and am running a Marantz AV-550 pre/pro and a Parasound 2003A amplifier. The parasound has the ability to auto turn on when a 12 volt signal is received. I have read through the Marantz owners manual and it states that the Marantz can trigger other Marantz amplifiers through a wire (RC-5??? I think) connection. Does anybody know if the Marantz's signal is 12 volts? The owners manual does not state this specification. If so, can I use the correct pin input for the back of the Marantz and the split the wire for input into the Parasound amp? The Parasound has a + and ground input I believe? Any help would be appreciated.
