An AC mains switch is located adjacent to the power cord on the rear panel of the amplifier. This switch may be used to disconnect the supervisory power supply from the AC mains without having to actually unplug the amplifier from the wall outlet. Since this small supervisory supply controls the main power supply�s access to AC power, shutting down the supervisory power supply also disconnects the main supply from AC. If you plan to be away for an extended period, or have any other reason to turn the amplifier completely off, you may either unplug the amplifier or you may use the AC mains switch.
Note:
When first connected to the AC mains, the amplifier normally draws a small amount of power which is used to control the power-up sequence. Turning off the rear panel switch disconnects even this small power supply; you must turn this switch back �on� before you can enter the power-up sequence described in Front Panel, item #2, or before the amplifier will respond to a remote turn-on command.
Two fast-acting 30 ampere fuses are located inside the Nº336, on the AC mains module. The Nº335 uses two 15 ampere slo-blo fuses, and the Nº334 uses two 10 ampere slo-blo fuses. The protection circuitry has been designed such that only a catastrophic failure could cause these fuses to blow. As a result, if you suspect that your AC fuses have blown, disconnect your amplifier from the AC mains and contact your Mark Levinson dealer for assistance. Do not attempt to replace these fuses yourself.
