NOTE

Even if the unit is switched to standby, some of the circuits are still active. If you will not be using this unit for a prolonged period (due to a holiday etc), remove the power plug from the wall socket.
Furthermore, to prevent unexpected accidents, make sure the power plug is located where it can be removed at any time.

You can connect this unit to a Marantz AV 10 Preamplifier with an AMP CONTROL jack using the included cable and perform operations for both units simultaneously, such as turning the power on or off. link
