TROUBLESHOOTING

Incorrect operation is sometimes mistaken for malfunction. If problems occur, see this section for troubleshooting information. If
problems persist, contact your authorized Mark Levinson dealer.
NO POWER
Examine the power cord to ensure that it is connected to both the AC mains connector and a working, unswitched electrical outlet.
Make sure the amplifier is powered on with the rear-panel Power switch. Examine the electrical circuit breaker to ensure that power is being
supplied to the electrical outlet to which the amplifier is connected.
Make sure the amplifier is not in standby. The front-panel standby LED illuminates fully and continually when the amplifier is On. The LED flashes
Red slowly when the amplifier is in Standby mode.
When the amplifier is configured for Green or Power Save mode, it will automatically put itself in Standby after 20 minutes without any input signal.
Make sure the amplifier is not in a fault condition. Faults are indicated by the front panel LED flashing or steadily glowing white. See the Fault
Section on Page 17 for more information about faults.
NO SIGNAL AT THE OUTPUTS
Examine all audio cables to ensure a solid connection between the amplifier and all associated components. Examine the speaker cables to ensure
a solid connection between the amplifier and the amplifiers. Make sure that the connected speakers are operational. Make sure the volume is set
to an audible level.
Make sure the preamp is not muted. Make sure the preamp's Offset setting for the selected input is not reducing the volume to an inaudible level.
Make sure all associated components are connected to working electrical outlets and powered on. Make sure the source device connected to the
amplifier's selected input is producing an output signal.
AUDIO HUM
Disconnect components one at a time to isolate the problem.
Once the problem is identified, make sure the problematic component is properly grounded and connected to the same electrical circuit as the
amplifier.
Make sure the Input Ground toggle switches are set correctly and that the switch handles are moved completely to the appropriate side.
NO NETWORK CONNECTIVITY
Verify that the network cables are properly connected between the router, switch or hub and the preamp.
Verify the age of the router, switch or hub. If the router, switch or hub is more than ten years old, there may be a communication issue with the
preamp. Power cycle the preamp and use a newer router, switch or hub between the network and the preamp.
IF ALL ELSE FAILS...
Power cycle the amplifier with the rear-panel Power switch, waiting at least 10 seconds between powering the unit off and on.
Restore factory-default settings (See Advanced: Settings Changes via USB).
