I’m trying to hook-up my Denon POA-5200 dual power amplifier to my Denon AVR-X4100W receiver using the remote on/off switch so the amplifier will turn on automatically with the receiver but I can’t figure out what plug type I need for the back of the amplifier. I looked in the manual and it says to use the cable supplied with it but this unit was my dads originally so I don’t have that cable. Can anyone tell me what plug/cable type I need? I know I need a 3.5mm male plug for the receiver side but I just can’t figure out the amplifier side. Thanks in advance!
