TROUBLESHOOTING
Before removing youramplifier.referto the
list
below and follow the
suggested procedures. Always test the speakers and their wires first.
AMPLIFIER WILL NOT POWER UP.
Check
for
good ground connection.
Check that remote DC terminal has
at
least 1
OV
DC.
Check that there is battery poweron
the+
terminal.
Check all FUSES.
Check that Protection LED is not
lit.If
it is lit, shut
off
amplifier
briefly and then repower it.
HIGH HISS OR ENGINE NOISE(ALTERNATOR WHINE) IN SPEAKERS.
Disconnectall RCA inputs to the
amplifier
,
if
hiss/noise disappears ,then
plug in the component driving the
amplifier
and unplug its inputs .
If
hiss/
noise disappears,
go
on until the faulty/noisy componentis found.
It is bestto
set
the
amplifier
input level as insensitive as possible.The best
subjective S/N ratio is obtainable this way .Try to drive as high a signal level
from the head
unit
as possible.
PROTECTION LED COMES
ON
WHEN THE AMPLIFIER IS POWERED UP.
Check for shortson speakerleads.
Check that volume control on the head
unit
is turned down low.
Remove speaker leads ,and reset the amplifier.
If
the Protection LED still comes on ,
then the
amplifier
is faulty.
The
amplifier will shutdown automatically when the units· temperature goes up to
as
•c
This will protect the unitsfrom damage.
AMPLIFIER'S GETS VERY HOT.
Check that the minimum speaker impedance for
that
model is correct.
Check
for
speakershorts.
Check that there is good airflow around the amplifier.In some applications,
an external cooling fan may be required.
DISTORTED SOUND.
Check that the Level
control's
is
set
to match the signal level
of
the head unit.
Check that all
crossover
frequencies have been properly
set
.
Check
for
shortson the
speaker
leads.
HIGH SQUEAL NOISE FROM SPEAKERS.
This is always caused by a poorly grounded RCApatch cord.
WARNING!
1. Over high volume will damage your speakers.
2. Be cautious when you use the amplifier neargasoline tank and electric wires.
3. Protect the connecting wires and parts to avoid any damage
or
short circuit.
4. The power
must
belee from the anode
of
the batteryvia FUSE.
5. The sound system
must
be in
turning-off
situation when you check the amplifier.
6. Be sure
that
you use the same type
of
FUSE when you need to replace
it
.
