Danger!

4.No audio and the front panel indicator LED is lit at full brightness.

•The Nº33H is powered on, but is not passing a signal. Power the Nº33H off with the ~ac mains relay switch, then examine the signal cables to ensure a solid connec- tion between the Nº33H and the associated preamplifier and loudspeakers.

Power the Nº33H off with the ~ac mains relay switch before touching the loudspeaker wires.

5.The Nº33H keeps powering off.

•A fault condition may be present at the input (for exam- ple, a DC signal from the preamplifier) or the output (for example, short-circuited loudspeaker wires). If this occurs:

a.Power the Nº33H off with the rear panel ~ac mains relay switch.

b.Disconnect the input signal and loudspeaker wires.

c.Wait 10 seconds.

d.Power the Nº33H on with the ~ac mains relay switch.

If the Nº33H powers on without entering standby, a fault

condition is present at the input or the output. To isolate 21 the problem:

a.Power the Nº33H off with the ~ac mains relay switch.

b.Reconnect the loudspeaker wires.

c.Power the Nº33H on with the ~ac mains relay switch.

If the Nº33H powers on into standby, the fault condition is present at the input. If not, the fault condition is pres- ent at the output.

6.If all else fails...

•Power cycle the Nº33H with the rear panel ~ac mains relay switch, waiting at least 10 seconds between powering the Nº33H off and on.

•Contact an authorized Mark Levinson dealer.
