Troubleshooting and Maintenance

Earthquake Sound

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.

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. 

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.
