INTEGRATED AMPLIFIER
Troubleshooting
NO SOUND FROM THE UNIT
If the unit is not reproducing audio take the following steps:
•
Check the source is correctly connected to an appropriate input on the unit.
Refer to the Installation & Operation section on page 14.
•
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 unit is set to select the correct source input. Adjust the ‘Source’
selector for the correct source component.
•
Check the volume. Turn the unit volume 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 Mute. If the Display LED is dim, this indicates the unit is in
Mute mode. The Display LED should be full brightness for operational mode.
•
Check the processor switch setting. This must be set to ‘Bypass’ (towards the
Speaker outputs) when using source components connected to the unit. Set
Processor Bypass to ‘ON’ for listening to sources via the processor or home
theatre equipment.
SOUND IS QUIET OR DISTORTED
If the sound is quiet or distorted a rail fuse may have failed. While the unit is ON
check the fuses in the rear panel. 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 or be in thermal overload protection mode.
•
Mains Fuse Failure: Check the mains fuse and replace if needed.
•
Thermal Overload Protection: Assess the temperature of the unit. If the unit seems
excessively hot, the Over Temperature Protection may have activated.
Refer to the Product Features section on page 18 for further information.
NOTE: If the unit immediately or repeatedly suffers mains fuse failure or thermal overload
protection, there may be a major problem and you should contact your Plinius dealer.
