This MXD file contains discrete commands for operating Zone 2 in a Marantz Receiver. Page 1 is left blank for your custom macros. Pages 2 and 3 contain the discrete inputs. Page 4 contains discrete On/Off for Multi and Multi-Speaker, as well as discrete volume and mute for Multi and Multi-Speaker. These commands work through the front IR sensor on the receiver, or for the rear IR in. They will not work using the Multi-RC input on the back of the receiver.
