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 .

When input audio signal from HIGH INPUTport can start amplifier working directly instead of using
REM cable from POWER.
2.LOWINPUT
Left and right channels inputs of the amplifier system. Preamplifier outputs of a source
( head unit.CD player,DAT,etc. )
or of an external electronic crossover must be connected to them.
