About Cinénova Amplifiers
Your Cinénova Grande
Thank you for purchasing this Cinénova Grande reference amplifier designed to
satisfy your audiophile needs for music enjoyment. The Cinénova Grande is
conceived to reproduce “true to life” music as it was originally recorded, without
tempering, coloration or compression.
“Sounding good” and “looking good” are both integral characteristics of a
Cinénova amplifier. The elegant industrial design is only surpassed by the
sturdy chassis upon which the amplifier is built. 12 gauge steel is shaped to
house the “Alpha One” modules and transformer. The chassis is beautifully
faced with an 8 mm aluminum plate, hand engraved and available in both Black
and Platinum finish.
Like the finer things in life, the Cinénova Grande was conceived with love for
details, hunger for power, and respect for grace. The Cinénova Grande enjoys
the solitude of being the most powerful multichannel amplifier on the planet.
Your Cinénova 7
Most home theater systems sold to consumers integrate low power amplifier /
receiver units, normally not exceeding 150 Watts per channel. However,
professional theater systems employ individual components which provide the
best separation and potentially a lot more power. Audiophiles know that an
audio amplifier is the heart of any system; it must be able to meet the demands
of the softest musical passage to the thundering special effects of a movie,
without sacrificing audio quality.
Thank you for purchasing this Cinénova 7 state of the art multi-channel
amplifier. This amplifier is designed to surpass your expectations and satisfy
your audiophile needs for music and movie enjoyment. The Cinénova 7 is
conceived to reproduce “true to life” music as it was originally recorded, without
tempering, coloration or compression. Created in the image of its larger
brethren, the Cinénova 7 is an uncompromising design built upon massively
over-specified components. Using power dense transformers exceeding 2800
VA and completely self-contained output blocks, the Cinénova is a septo
monaural amplifier. Completely separate output blocks are largely unheard of in
this class of amplifier, but with Earthquake’s enduring strive for quality and
excellence there simply was no other way. Designs that share a common
motherboard inherently lack the fidelity of true separate designs. The Cinénova
7 is ready to take on even the heaviest of speaker and hold it in an iron grip.
Large vertically-ripped individual heat sinks efficiently release heat and ensure
that your show goes on no matter the intensity. From the loudest crescendo to
the finest syllable, the Cinénova will remain composed and in control. Enjoy the
unique ownership experience of this Cinénova that was designed by a brilliant
mind and built with loving hands.
The Cinénova Grande’s untainted sonic quality is only matched by its enormous
power and stringent technical performance. The finesse of high-fidelity audio,
combined with the mastery of multi-channel amplification make the Cinénova
Grande the cornerstone for a high-end home theater setup. This amplifier
caters to both the music aficionado and the home cinema buff. After all, faithful
reproduction of music is our business.
The unique Cinénova technology integrates a minimum number of components
in the audio path, leading to excellence in sound quality, efficiency, and clean
amplification. Working side by side with engineers from Toshiba, our engineers
helped develop one of the fastest transistors in the industry, a 15 Giga-Hertz
switcher. Fast, accurate, and powerful, the 15 GHz switcher allowed engineers
to use a smaller number of components in the audio path and reduce the need
for high bias current, making the Cinénova amplifiers industry-leading in power
efficiency. They are truly green amplifiers that do not sacrifice quality. Users are
able to enjoy pure music, untainted by components distortion or guilt from a
large carbon footprint.
Constructing a Cinénova is a fun process. From hand assembling, calibrating,
burn testing, and packaging, every step is conducted with love for details and
hunger for perfection. We enjoyed building your Cinénova and we know you will
feel the same using it.
Fromour hands toyour ears...Thank you.
Earthquake Engineers, driven by their desire for excellence, pushed the
envelope beyond its limits. They designed the “bi-file” Ferrite/OFC toroidal
transformer circuit witch allows five or seven separate power supplies (one for
each channel) to be magnetically coupled to one huge single primary 4KVA
transformer. The 99% efficient power supply permits large amount of current to
flow through.
The “Alpha One” is a monaural 1000 watt amplification/power block, used in
both the 5-channel and 7-channel Cinénova Grande amplifiers. The “Alpha
One” blocks are individually removable using the Earthquake patented “EZXS”
system, without the need to dismantle the rest of the amplifier. Channel
separation exceeds the norm of 90 decibels and stretches it to110 decibels.

1. Replaceable Fuses:
8. Gold Plated Speaker Output Binding Posts:
Each mono block has two (10Amperes) fuses designed to
protect and monitor the voltage of operating rails (+/-). If a
fuse burns out you may replace it with the following fuse
size: 10A - 250V, 5mm x 20mm, mini fuse slow blow. If
fuses continue to blow check for shorts in the wiring
system.
We recommend that you use a high quality wire
constructed of fine, multi-strand copper 10-gauge and up.
Wire with a gauge of 16 may be used for short runs of less
than twenty feet. We do not recommend that you use any
wires with a gauge equivalent of 18 or higher due to the
power loss and performance degradation.

2. RCA Input:
9. Main Circuit Breaker
Accepts low-level signal from any source. It takes 1.6V to
output the rated power.
The enormous amount of power generated
by the amplifiers requires a stable 120 or
240V connection. Your amplifier is supplied
with a heavy-duty 20A circuit breaker. If
power to your amplifier is interrupted, check
the circuit breaker on the rear of the unit. If
the breaker is in the off position you may
reset it to the on position to restore AC
power. If the circuit breaker automatically
trips tothe offposition.
3. Input Selector:
To maintain signal integrity Cinénova-7 provides you with
an “Input Selector Switch”. This gives you (installer) the
option to select between RCA or XLR inputs.
4. Fully Balanced XLR Inputs:
We recommend the use of fully balanced XLR inputs in
cases when the distance between the Cinénova and the
audio source is excessive and susceptible to noise
interference.
To ensure proper operation, we
recommend a dedicated 20amp circuit
breaker because a proper power supply
translates to better performance. Most
homes are wired with 20A circuits, but there is a chance
that the wall receptors are rated at 15A. IF IN DOUBT,
CONSULTWITHAN ELECTRICIAN.
5. Three-way Crossover Switch:
A 3-way switch controls the operation of the output filter.
The amp can run in full-range, low-pass, or high-pass
mode tobe used for different applications.
10. AC Input Connector
6. Variable Crossover 20Hz-5kHz:
A special heavy duty - 20 Amperes - AC cord is included
with every unit. Do not attempt to replace theAC cord with
lesser quality AC cords.
Each monaural block features a built-in variable filter to
select the desired frequency range, with a slope of
12dB/Octave. The fully buffered filter has a range of 20Hz
when set to minimum to 5 kHz when set to maximum. This
V/R is inactive when crossover switch is in by-pass mode.
11. 12VDC Trigger
In order for the Cinénova Turn-ON to be controlled via
another source, connect the 12VDC trigger input to the
12VDC source output (polarity is not an issue). From your
source, 12VD should have over 20mA. Then set the
manual power switch to OFF and the circuit breaker to ON.
Now any time the Cinénova detects an incoming 12VDC
signal it will automatically power on.
7. Fused Fault Indicators:
Each fuse carries its own fault LED indicator that
illuminates when the fuse is burnt.

EZXS Detachable Monaural Blocks:
?Independent amplification blocks & power supplies
Five or seven totally independent mono-block amplifiers each with its
own power supply circuitry and pre-amplification stage for high fidelity
audio reproduction. For ease of service, each block can be individually
removed and serviced without the need to ship the entire amplifier.

?Built-in line conditioner
?5-channel and 7-channel configurations
?Soft Start Circuitry
Multiple Heat Sinks:
?Fully balanced inputs
Over 500 square inches of heat radiating aluminum surface per
channel maximizes heat exchange for cooler amplifier operation. The
12 gauge steel cover is perforated - top, sides & bottom- for effective air
circulation.
?12VDC trigger input
?Three-way mode selection switch: High-pass, By-pass &
Low-pass
Peak LED Indicators:
?20Hz-5kHz variable crossover for each channel
These LEDs monitor the corresponding channel’s output level. The
LEDs will come on only when the amplifier output reaches its maximum
level, near 1%THD. If an LED flickers that is ok. If an LED should remain
on for longer than 10 seconds then simply back the volume down
slightly tomaintain a stable level of output.
?Oversized bifilar toroidal power transformer with
extraordinarily low DC resistance and thermal protection
?Fuse Fault Indicators
?Thermal protection against overheating
?Individually selected and matched components
?Speaker protection against DC and frequencies below 10Hz
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
this nature during normal or high power operation.
?Protection against short circuits, device failures, miss wiring,
and internal faults
?Heavy duty gold plated output terminals
?Front mounted removable handles
Individually Selected and Matched Components:
Components used to construct the Cinénova Grande are subjected
to an exhaustive selection process; during which, the components
are matched and individually tested to exact tolerances. Which leads to
the impressively low idling current of 600mAfor the 5ch Cinénova.
Note:
Toroid Power Transformer:
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
you hear any audio through the speakers. This time delay is essential as
it slows down the rushing current at initial start up, allowing it to slowly
charge the huge capacitor banks without tripping the main circuit
breaker.
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, insulated with 10 layers of pressed foam.

Cinénova Power Amplifiers
Trouble Shooting and Maintenance
Troubleshooting Cinénova Grande 5 or 7
Troubleshooting All Cinénova Models
Amplifier “ ON” No Sound
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 orange) it means that the
amplifier output is clipping. Reduce volume level to prevent damage to
speakers or amplifier.
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.
Humming noise from speakers
Often humming noise is emanating from equipment that have their
ground prong broken. To isolate this problem:
d) Set the crossover switch so that it is centered. Slide it up and down and
finally back to the middle position.
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.
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:
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.
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.
Maintenance
WHEN NO THUMP IS HEARD:
i) Check amplifier speaker connections.
The following maintenance should be performed routinely:
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.
! 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 toremove dust fromits interior & exterior.
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.
- For Cinénova 7 only
Circuit Protection
The Cinénova 7 is protected with optical short circuit protection. If it is tripped,
the shorted channel will mute and reset every 7 seconds. If fault remains, it
will stay in mute mode. We recommend to swap the speaker with a
guaranteed working speaker and see if the channel works.
