Troubleshooting
NOTE:

Amplifier “ON” No Sound
a) Completely shut your system down including your Cinénova via the
circuit breaker.
b) Now turn on the Cinénova 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>>>
g) Check your input source signal. Make sure they are connected
properly to output from processor/source, (not input of processor).
h) Try to change source to make sure that at least one of the sources
works.
WHEN NO THUMP IS HEARD>>>
i) Check amplifier speaker connections.
j) 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.

Peak LEDs “ON” Constantly
Humming noise from speakers
It is normal when running the amplifier to full power that the LEDs
flicker. If the LEDs are on constantly without flickering (solid orange) 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
g r o u n d p r o n g b r o k e n . To i s o l a t e t h i s p r o b l e m :
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.

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.
!
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.
The following maintenance should be performed routinely:
