OPERATION/ADJUSTMENT
Apply power to the system. Amp will come on after a slight delay. Turn volume
control up on tape deck or radio. If power output is adequate, leave gain control
where it is. If volume is low slowly increase gain on the amplifier by turning the
gain clockwise with a screwdriver. On some radios, which have very low-level
outputs, a Preamp or Line Amp may be necessary.
NOTE: IT IS VERY IMPORTANT THAT THE GAIN CONTROL BE TURNED
DOWN AS FAR AS POSSIBLE. IN ORDER THAT UNWANTED ENGINE NOISE
BE KEPT TO A MINIMUM.
GENERAL TROUBLESHOOTING
NO SOUND: Check all connections. Check main power fuse. Check accessory
fuse. With a trouble light or meter be sure +12V is present at the amplifier on (1)
The large Red Wire (2) The (Red/White) wire but not at the large Black. Check by
substitution or other method for proper operation of music source.
BLOWS FUSE: Check all connections to be sure all power wires and speaker
wires do not touch ground or each other. Re-check polarity of main power wires.
SHUTS OFF: As this amplifier is equipped with a thermal and a short circuit
shutdown system in the unlikely event of excessive temperatures due to high
ambient temperature, improper speaker impedance, etc. The amp will turn itself
off. If this happens, the amp will turn itself back on when cool enough. To avoid
damage to the speakers, turn the volume to a minimum while waiting for the amp
to turn itself back on.
NOISE NOTES
Unwanted noise is the worst single problem encountered in automotive amplifier
installations. Most noise problems start at the music source. Your LINEAR
POWER amplifier will accurately reproduce any sound present in the signal path.
NO amplifier can discriminate between music and engine noise. Several basics
must be kept in mind when preventing noise problems.
1.The hookup method with the least noise in one vehicle may be the noisiest in
another.
2.Most noise problems start at the music source. Your LINEAR POWER™
amplifier will accurately reproduce any sound present in the signal path. NO
amplifier can discriminate between music and engine noise.
