I have a Marantz cd player model CD-65, On the rear it has 5 RCA connections marked Easy, Remote and Rec Sync. I assume that the Easy and Remote are the bus connections used for devices that don't directly have there own remote. and are conected to the Remote in/out of and existing marantz amplifier. I have tried connecting both Easy and Remote Bus connectors to both my Marantz amplifiers. My new AV SR7500 and Older Stereo Receiver SR-65 but haven't had any luck getting the remote working. (either the Original sr65, a Marantz and Sony programable using the marantz cd code) Can somone please explain for me what the difference is between the easy and remote connections on the cd player and which of the 4 rca connectores should I use as they are all marked the same color.
