Humming noise from speakers.
Often humming noise is emanating from equipments that
have their ground prong broken.
a) With the amplifier OFF, unplug all RCAs connected to the
amplifier.
b) Turn on amp and listen to speakers.
If buzz has changed or reduced in level, then the problem
is coming to the amp from another source. The rest of the
hum you hear is normal and related to the fact that the
RCAs are open ended and not connected to any thing.
c) If above steps do not isolate your problem: star-ground all
components except amplifier from their chassis to the
processor.
Front LEDs are ON all the time
It is normal when running the amplifier to full power that the LEDs
flicker. If you see that the LEDs are on constantly without
flickering (solid orange) it means that the amplifier is clipping.
Reduce volume level to prevent damage to the unit.
Turn amplifier ON and circuit breaker shuts down
This can either be a short in amp or poor circuit breaker in the
house. Plug amplifier into another outlet on a different circuit
breaker with nothing connected. If the amp turns on then the
problem is with your home circuit breaker. If the amplifier still does
not power up, please call Earthquake to consult with a technician.
The following routine maintenance should be performed on a periodic
basis:
?Clean the exterior surfaces of the unit with a soft, dry, lint-free cloth.
?Do not use alcohol, benzene, acetone-based cleaners, or strong
commercial cleaners.
?Do not use a cloth made with steel wool or metal polish.
?If the unit is exposed to a dusty environment, a low-pressure
blower may be used to remove dust from its interior & exterior.
