Why does my Marantz MM8077 Amplifier power suddenly switch off during use, and the STANDBY and protection indicators flash?

This issue may occur because the internal temperature of the unit has increased, activating the protective circuit. To resolve this, remove the power plug from the wall socket, allow the unit to cool down, and then reinsert the power plug. Ensure the unit is installed in a well-ventilated location and that you are using speakers with the specified impedance. Also, check for any stray core wires from the speaker cables touching each other or the rear panel of the unit; if found, correct the wiring before reconnecting. Lastly, try turning the volume down on the connected amp before reinserting the power plug.
