Troubleshooting

NO SOUND FROM THE UNIT

If the unit is not reproducing audio take the following steps:

• Check the preamplifier is correctly connected to an appropriate input on the unit.

• Check the source is playing, and not paused or muted. If it has adjustable volume, check this is at the usual output level.

• Check the preamplifier is set to select the correct source input. Adjust the source selector for the correct source component.

• Check the volume. Turn the unit volume on the preamplifier up to a point just below the normal listening level. DO NOT turn the volume up to maximum in case the sound begins to come through the speakers.

• Check the unit is not in Standby. If the Standby LED is ON this indicates the unit is in Standby mode. The Standby LED should be OFF for operational mode.

• Check the unit is not in Mute. If the Mute LED is ON this indicates the unit is in

Mute mode. The Mute LED should be OFF for operational mode.

SOUND IS QUIET OR DISTORTED

If the sound is quiet or distorted a rail fuse may have failed. While the unit is ON look through the ventilation slots in the top cover. A Red LED being on will indicate a fuse failure. If the fuse has failed, see Fuse Protection in the Product Features section of this manual.

NOTE: If the unit immediately or repeatedly suffers rail fuse failure, there may be a major problem and you should contact your Plinius dealer.

POWER FAILURE

The unit may have suffered mains fuse failure.

• Check the mains fuse and replace if needed. Refer to the Product Features section for further information.

NOTE: If the unit immediately or repeatedly suffers mains fuse failure, there may be a major problem and you should contact your Plinius dealer.
