Troubleshooting

Incorrect operation is sometimes mistaken for malfunction. If
problems occur, use this section for troubleshooting information. If
problems persist, contact your authorized Mark Levinson dealer.
1. E xamine the power cord to ensure that it is connected to both
No Power
the rear panel connector of the amplifier and an electrical
outlet.
2. Make sure the amplifier is powered on with the Power switch.
3. Make sure the amplifier is not in Standby mode. The front
panel LED should be at full brightness.
4. E xamine the electrical circuit breaker to ensure that power
is being supplied to the electrical outlet to which the amplifier
is connected.
5. V erify that the voltage rating on the rear panel of the amplifier
matches the voltage rating of the electrical outlet. If the
voltages do not match, no power is sent to the outputs of
the amplifier.
1. Make sure that the source device is powered on, playing audio,
and set to the right output connector.
2. E xamine cables to ensure a solid connection between the
amplifier and associated components.
3. Make sure the amplifier's output connectors are connected to
operational loudspeakers.
4. Ensure that the amplifier is not in a fault condition. When the
amplifier experiences a fault, the output is muted and the Status
LED on the front panel blinks in a rapid pattern, indicating:
LED Behavior
Rapidly blinking
(on most of the time)
Rapidly blinking
(on half of the time)
Rapidly blinking
(off most of the time)
*Signal-related faults include significant DC offset at the output due to either DC in the input
signal or a failed component within the amplifier OR excessive current demands due to a
short-circuited loudspeaker wire.
You must assign the slave from the master device. Verify that the
slave you want to assign is listed in the master device list and
check its current state. For further explanations on assigning slave
devices, refer to the owner's manual of the master device.
