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

  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.

  First, verify that the power plug is correctly inserted into the wall socket. If the issue persists, the protective circuit may have been triggered. Remove the power plug from the wall socket, wait at least one minute, and then reinsert it.

Why does my Marantz MM8077 Amplifier power off suddenly and the standby indicator flashes?

  Sarah LambertAug 25, 2025
  If your Marantz Amplifier suddenly switches off during use, and the STANDBY and protection indicators flash, it could be due to several reasons. The internal temperature of the unit might have increased, triggering the protective circuit. To resolve this, remove the power plug, allow the unit to cool down, and then reinsert the plug. Ensure the unit is installed in a well-ventilated area. Also, verify that you are using speakers with the specified impedance. If speaker wires are touching or a core wire is causing a short by touching the rear panel, remove the power plug, fix the wiring, and then reconnect. Finally, try turning down the volume on the connected amplifier before reinserting the power plug.

  If your Marantz Amplifier doesn't switch on, or it switches off immediately after being switched on, ensure that the power plug is correctly inserted into the wall socket. Also, the protective circuit might have been activated. If this is the case, remove the power plug from the wall socket, wait for at least one minute, and then reinsert it.

  Alyssa NicholsSep 4, 2025
  If your Marantz Amplifier switches off suddenly during use, and the STANDBY indicator flashes quickly while the protection indicator flashes slower, the protective circuit has likely been activated. Remove the power plug from the wall socket, re-examine the installation conditions of the unit, and check the speaker cable connections.
