General Troubleshooting - Linear Power 5002 Owner's Manual And Installation Manual

In a basic system, using a single amplifier, set the amp gain to minimum, turn the
deck up until it just starts to distort, then back the deck down slightly. This is the
point where the output of the deck is cleanest. Now, bring the gain of the amp up
until it just starts to distort, and back it down slightly. This will allow the deck and
amp to reach maximum useable output at the same time.
WARNING
Your new LINEAR POWER™ amplifier, when used in conjunction with many of
the efficient speaker systems on the market today, can produce sound pressure
levels that are considered harmful to your hearing.
Exposure to loud music may lead to loss in hearing. This effect may not be
readily appreciated because the damage to hearing is progressive. Those who
are exposed to excessive sound pressure should utilize direct individual
protection in the form of earplugs or earmuffs, which are specifically designed for
noise reduction.
In accordance with the OSHA (Occupational Safety and Health Act) regulations
for noise levels as they relate to the work area, excessive sound pressure is
defined as 115db(a) continuous for any length of time.
We recommend that you exercise restraint while enjoying the performance of this
and other high-powered mobile audio equipment.

GENERAL TROUBLESHOOTING

NO SOUND Check all connections. Check main power fuse. Check accessory
fuse. With a trouble light or meter, be sure +12 volts is present at the amplifier on
the large positive cable and on the small red/white turn-on wire. Check for a good
ground connection. Check by substitution or other method for proper operation of
music source.
BLOWS FUSES 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 shut-
down system, in the unlikely event of excessive temperatures due to high
ambient temperature or improper speaker impedance, the amp will turn itself off.
To avoid damage to the speakers, turn the volume to a minimum while waiting for
the amp to turn itself back on.
