Most of home theater systems sold to consumers integrate low

channel. However, professional theater systems employ individual
components which provide the best separation and potentially a lot

any system; It must be able to meet the demands of the softest musical

Cinénova Grande Power Amplifiers
Location Considerations
The Cinénova Power Amplifiers require care during installation to ensure
optimal performance. These amps should be installed in or on an extremely
sturdyandlevelsurfacewithoptimalbreathingroom(atleast2inchesofopen
spaceonallsides).
2) REMOVING THE AMPLIFIER 1) OPENING THE CRATE
This requires two
people: one to lift the
amp from its back and
another to lift the amp
f r o m i t s f r o n t .
Simultaneously lift the
amplifier slowly in an
upward motion using
the front handles and
the cover. This will
ensure that you do not
scratch the housing, or
much worse: hurt your
back or damage the
amplifier.
To open the crate,
release the two latches
holding the crate door.
Slowly lift the crate door
and inspect the content
of the crate (padding,
foam,ETC...).

Confirm the voltage setting of the amplifier. It must match the voltage in your
home. The amp is set by factory to either 120V or 240V. Check above the
circuitbreakerforthisinformation.

Special Features
Technology and Materials
Multiple Heat Sinks:
Over 500 square inches of heat radiating aluminum surface per
channel maximizes heat exchange for cooler amplifier operation. The
12gauge steelcoveris perforated-top, sides&bottom- foreffectiveair
circulation.
Peak LED Indicators:
These LEDs monitor the corresponding channel’s output level. The
LEDswill comeon onlywhen theamplifieroutput reachesits maximum
level,near1%THD.IfanLEDflickersthatisok.IfanLEDshouldremain
on for longer than 10 seconds then simply back the volume down
slightlytomaintainastablelevelofoutput.
Thermal Protection:
Each monaural block is equipped with a thermal sensor designed to
shut the amplifier down when it overheats. Overheating is not typical.
It only occurs if the amplifier is over driven with low impedance
speakers, or if the amplifier is located in an improperly ventilated
space. The Thermal Protection Circuit will kick in at 85ºC and
release at 65ºC. It is unusual for this amp to reach temperatures of
thisnatureduringnormalorhighpoweroperation.
Individually Selected and Matched Components:
Components used to construct the Cinénova Grande are subjected
to an exhaustive selection process; during which, the components
arematched andindividually testedtoexact tolerances.Which leadsto
theimpressivelylowidlingcurrentof600mAfor5chtheCinénova.
Toroid Power Transformer:
Each Cinénova contains a monstrous 4KVAhigh efficiency bifilar toroid
transformer. This ferrite core transformer weighs over 30Lbs and is
wound with oxygen free, 99% pure copper that minimizes transport
losses. Hum suppression is accomplished by using a 12 gauge toroid
mount,insulatedwith10layersofpressedfoam.
Note:
The soft start circuitry will cause a slight delay (around 6 seconds)
between the time when the amplifier is switched on and the time when

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 RCAor 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.

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
preventdamagetospeakersoramplifier.
Often humming noise is emanating from equipment that have their
gro und prong broken. To i sola te thi s prob lem:
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

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
withatechnician.
