REMOTE CONTROL jacks
Performing operations by RC on this unit without visual contact
You can connect an external IR receiver to the REMOTE CONTROL connectors to perform operations on this unit with the supplied remote control unit without visual contact. This might be necessary if the unit is hidden in a cupboard or corner, so you can’t directly point with the remote control unit to the device.
To do this, disable the remote control signal receiving function (Remote lock functionlink).
When the remote control signal receiving function is disabled, you can not perform operations with the remote control unit.
Remotely connecting Marantz devices
When you are using a Marantz device other than this unit that supports remote connection, you can transmit remote control signals just by connecting the device to the REMOTE CONTROL IN/OUT connector with a monaural cable.
Set the remote control switch located on the rear panel of the connected audio component to “EXTERNAL” or “EXT.” to use this feature.
