REMOTE
Terminal
to be connected with Remote cable, which comes from the source and which
controls the amplifier switching on.Applied voltage must be between 10 and 15 VDC.
GND
Ground terminai,Connect to the car chassis. Keep the length of the ground cable
to a minimum.
E) INDICATOR LIGHT
When this LED sends out blue light, it means that this amplifier have being working now.
When
this LED sends out red light, it means that the self-protection of the amplifier.
When
this LED sends out red ligh,Power amplifier overheating indicator.

TROUBLESHOOTING
Before removing your amplifier, refer to the list belowand follow the
suggested procedures.Always test
the speakers and their wires first.
AMPLIFIER WILL NOTPOWERUP.
Check
for good ground connection.
Check
that remote DC terminal has at least 1 OV DC.
Check
that there is battery power on the+ terminal.
Checkall FUSES.
Check
that Protection LED is not lit.lf it is lit, shut off amplifier briefly and then repower it.
HIGH HISS
OR ENGINE NOISE(ALTERNATORWHINE) IN SPEAKERS.
Disconnectall RCAinputs to the amplifier, if hiss/noise disappears ,then
plug in the component driving
the amplifier and unplug its inputs. If hiss/
noisedisappears, go on until the faulty/noisy component is found.
Itis best to
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 shorts on speaker leads.
Check
that volume control on the head unit is turned down low.
Remove speakerleads ,and reset the amplifier.
If the Protection LED still comes on ,
then the
amplifier is faulty.
The
amplifier will shut down automaticallywhen the units· temperature goes up to 85°C
This will protectthe unitsfrom damage.
AMPLIFIER'S GETS VERY HOT.
Check that the minimum speaker impedance for that model is correct.
Checkforspeakershorts.
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 setto match the signal level of the head unit.
Check that all crossoverfrequencies have been properly set.
Check for shorts on the speaker leads.
HIGH
SQUEAL NOISE FROM SPEAKERS.
This is always caused by a poorly grounded RCApatch cord.
WARNING I
1. Over high volumewill damage your speakers.
2. Be cautiouswhen you use the
amplifier neargasoline tank and electric wires.
3. Protectthe connecting wires and parts to avoid
any damage or short circuit.
4. The
power must beleefrom the anode of the battery via FUSE.
5. Thesound system mustbe 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.
* We reserve the rightto make needed change or improvement to the product,
without informing customer aboutthis in advance.
