If problems occour during the installation, or later,
this guide might help you to find out whats´s wrong.
THE AMPLIFIER IS DEAD:
1.
Check power lead, ground and remote connec
tions at the amplifier using a multi meter.
2.
Check the battery terminal connections.
3.
Check the power lead fuse or circuit breaker. If
fuse damage continues, inspect the power lead
for short circuits.
4.
Check the amplifier protection fuses. Are these
broken change to new ones with the same value.
If short circuiting continues, contact your local
DLS dealer. A fault may exist in the amplifier.
5.
To start the amplifier requires a remote voltage of
9-15 volt. Check the voltage with a multi meter.
AMPLIFIER PROTECTION FUSE BLOWS AT LOW
VOLUME :
1.
One or more speaker cables are shorted. Make an
insulation test with a multi meter. The cables must not
have a connection to earth.
THE AMPLIFIER TURNS OFF AFTER 10 - 30 MI-
NUTES.
The amplifier is overheating due to inadequate ventila-
tion. Check mounting position is free from obstruction.
Do this:
1.
Move the amplifier to a place with better ventil-
ation.
2.
Install one or two fans to cool down the heat-
sink.
3.
Overheating can also be caused by an
impedance load below the level permitted.
NO OUTPUT FROM ONE OR MORE SPEAKERS:
Check the following:
1.
Balance control position.
2.
Fader control position.
3.
Speaker cable connections to both ampli
fier and drivers.
4.
Signal lead plugs and cables.
5.
Change left and right signal lead plugs in the
amplifier to see if the problem moves to a diffe-
rent speaker, the lead has a fault.
If the problem remains, the speaker or amplifier
are at fault.
