Sayfayı Yazdır8. Troubleshooting
If the pre-amplifier fails to work or you
suspect it is not working properly, first
check all connections to and from the
other equipment. Check all the simple
and obvious things first: power supply
on at wall, power amplifier and source
components are switched on, loud-
speaker cables are secured at both
ends.
Below are some common problems
with suggestions for the possible cure.
The list is not exhaustive; if you cannot
resolve the problem yourself, please
consult your appointed ASTINtrew
dealer or distributor.
No power, LED fails to illuminate:
Check the wall and pre-amplifier power
switches are on; and that the power
cable is secure in the back of the
amplifier. Check fuses.
No output, no sound from loud-
speakers:
Check there is a source signal and you
are switched to the correct input.
Check the power amplifier and speak-
ers are working correctly.
Loud audible hum:
Check all component earthing in your
hi-fi system.
Low volume:
Check volume control setting. Check
input compatibility with source
equipment.
Output distortion:
Check input compatibility with source
equipment; signal may be set too high.
Mains voltage may be unstable or
'dirty'.
