circuitry
The built-in protection circuitry in the Lanzar
MAX
Series
amplifiers will disable the amplifier if it senses
an input overload, a speaker short circuit, or extreme
temperature conditions.
When the
circuit is activated by any of
these
the Protection LED will be
illuminated.
If this occurs, carefully inspect the system to
determine the source of the problem.
•
If the shutdown was a resu It of a thermal overload
condition, allow the amplifier to cool down before
attempting to restart it.
•
If the shutdown was a result of an input overload,
or speaker short circuit, be sure to correct the
condition before restarting.

If the noise is a "whine" whose pitch follows the engine speed, confirm that the amplifier and any other signal
sources (head unit, etc.) are properly grounded.
If the noise is a "clicking" or "popping· noise whose rate follows the engine speed, this usually means that the
vehicle is equipped with resistor spark plugs and wires, or that the ignition is in need of service.
