1- Power Switch: turns amplifier ON / OFF. Amplifier must be ON for the 12V
trigger and the music auto sensing modes / functions to operate.
2- Remote Eye: receives remote control signal.
3- Potect LED: “RED” color indicates that amplifier is in protection mode (short
speaker wire or other reasons. Turn OFF the amplifier immediately).
4- Clip LED’s (CH-A & CH-B): “RED” color indicates that the input signal on the
channel/s (A or B) is clipped (reduce volume on the clipped channel).
5- LCD Display Module: shows the amplifier status, menus and settings.
6- Button Switches: represent the functions keys.
7- Encoder Switch: controls the operation of the functions.
8- Left / Right RCA Inputs: feed line-level stereo (left / right) signals into the
amplifier. NOTE: either left or right RCA jacks can be used to feed a mono input.
9- Left / Right XLR Balanced Inputs: feed balanced line-level stereo (left/right)
signals into the amplifier. NOTE: either left or right XLR jacks can be used to
feed a mono input.
10- Stereo / Bridged Switch: use this control / function when running the
amplifier in bridge or in stereo mode only.
11- External Trigger Input: powers up / triggers ON the amplifier from other
devices such as processors, receivers or any device with 12 Volts trigger output.
12- USB Port: for operating the amplifier and / or uploading new firmware.

Amplifier “ON” No Sound
Turn amplifier ON and circuit breaker shuts down
This can either be a short in amp, a poor circuit breaker in
the house or the power cord is not fully connected. 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.
Humming noise from speakers
Peak LEDs “ON” Constantly
It is normal when running the amplifier to full power that the
LEDs flicker. If the LEDs are on constantly without
flickering (solid red) it means that the amplifier output is
clipping. Reduce volume level to prevent damage to
speakers or amplifier.
Often humming noise is emanating from equipment that
have their ground prong broken. To isolate this problem:
a) With the amplifier OFF, unplug all RCAs connected to
the amp.
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.
c) The above step should isolate your problem: star-
ground all components, except amplifier, by daisy-
chaining a thin wire from the processors chassis to all
sources connected to it.
The following maintenance should be performed routinely:
- 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.

Trouble Shooting and Maintenance
b) Now turn on the amplifier only. Check to see if the front
Main Power Switch is on.
c) Check the Input Selector switch and make sure that it is
in the correct position. Either RCA or XLR which ever
you are using. Also slide the Input Selector switch back
and forth to ensure good contact.
d) Set the crossover switch so that it is centered. Slide it up
and down and finally back to the middle position.
e) Confirm that the output wires are connected to the
speaker.
f ) Rock the crossover switch back & forth at the amplifier,
you should hear a thump through the speaker during
this process.
WHEN A THUMP IS HEARD:
Check your input source signal. Make sure they are
connected properly to output from processor/source,
not input of processor.
Try to change source to make sure that at least one of
the sources works.
WHEN NO THUMP IS HEARD:
Check amplifier speaker connections and make sure
the speaker wires are securely connected to the
amplifier speaker output and to the speaker.
NOTE: It is possible that if you have proper
connections and you don’t hear sound, the speaker is
burnt.
a) Completely shut your system down, turn OFF the
Power switch in the front of the amplifier (see
Page 6 , #1).
We recommend that you first call the dealer where
you purchased the amplifier. If Problems Persist,
