Troubleshooting

NOTE:

Visit www.earthquakesound.com for answers to frequently asked questions and additional troubleshooting information.

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:
