In the event you have any question, please contact our toll free number at 1-800-576-7944 and ask for tech support.
1) OPENING THE CRATE 2) REMOVING THE AMPLIFIER 3) CONFIRM VOLTS SETTING
Confirm the voltage setting of the amplifier. It must match the voltage in your home. The amp is set by factory to either 110 V or
220V. Check sticker to confirm setting.
To o p e n t h e c r a t e , release the two latches holding the crate door.
Slowly lift the crate door and inspect the content of the crate (padding, foam, ETC...).
This requires two people: the front handles and the one to lift the amp from its cover. This will ensure that back and another to lift the you do not scratch the a m p f r o m i t s f r o n t housing, or much worse: simultaneously. Lift the drop the amplifier. amplifier slowly in an u p w a r d m o t i o n u s i n g
4) RESET CIRCUIT BREAKER 5) TURN POWER SWITCH ON 6) CHECK “FFI” LED INDICATORS
This amp is equipped with a
20 ampere circuit breaker.
The circuit breaker should be set to the OFF position before powering. Plug the
AC power cord into the amp and the wall, then reset the circuit breaker to ON position.
Turn the power switch ON.
When the red light turns on, proceed to step 6.
Each amplifier block comes equipped with 2 FAULT

About The Cin énova Grande Amplifiers
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.
Like the finer things in life, the Cinénova Grande was conceived with love for details, hunger for power, and gratifying grace; consequently ranking it “at the top” in the realm of High Fidelity.
Most of 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 agree 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.
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 multichannel amplification, make the Cinénova Grande the cornerstone for a high-end home theater setup. This amplifier caters to both the music afficionado and the home cinema buff. After all, faithful reproduction of music is our business.
The Cinénova Grande t echn ology integrates minimum number of components in the audio path, leading to excellence in sound
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,
Professor Joseph J. Sahyoun;
President & Chief Engineer
Getting Started accurate, and powerful, the 15 GHz switcher allowed engineers to use less number of components in the audio path. U sers are able to enjoy pure music, untainted by components distortion.
Earthquake Engineers, driven by their desire for excellence, pushed the envelop beyond its limits. They designed the "bi-file" toroidal transformer circuit witch allows five separate power supplies (one for each channel) to be magnetically coupled to one single primary 4KVA transformer. The 99% efficient power supply permits large amount of voltage to flow through with near nil heat losses.
The "Alpha One" is a monaural 1000 watts 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 norms of 90 decibels and stretches it to 110 decibels.
"Sounding good" and "looking good" are both integral characteristics of a Cinénova Grande 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.
Constructing a Cinénova Grande 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 Grande and we hope you will feel the same using it.
From our home to your home... Thank you.
Individually hand assembled and tested, these Monsters are lined up for final packaging. Wood crates are used to package these 130lbs (+) amplifiers to prevent any damages during shipping.

Front Panel Overview
1. POWER SWITCH
Disconnects power to the AC input connector. Set this switch to
OFF when making or breaking connections to the amplifier, or when changing the setting of the MODE switch.
2 . PEAK LED INDICATOR:
The Cinénova Grande is equipped with five or seven LED indicators on the front panel. These LEDs indicate the operating status of each corresponding channel. If an LED or all LEDs remain lit continuously, the amplifier is clipping and the volume should be turned down immediately to prevent damage. If the
LEDs are simply flickering, the amplifier is close to it’s limits and should not be pushed any further.
Basic Operation
Rear Panel Overview
1. RCA INPUT
Each channel is capable of being run with balanced XLR inputs or RCA inputs. Using RCA inputs is a lower cost solution that delivers great results for any home theater.
2. INPUT CONTROL
To maintain signal integrity CineNova-7 provides you with an
“Input Selector Switch”. This gives you (installer) the option between RCA or XLR inputs.
3. BALANCED XLR INPUT
The Cinénova Grande amplifiers come equipped with our new
Balanced XLR inputs. The use of XLR inputs is a more balanced and high-performance approach to connecting your home theater system.
4. BYPASS SWITCH
A 3-way switch controls the operation of the filter; with a simple flick of the switch, the amp can run in full range, low pass, or high pass mode.
5 . FUSED OPERATION INDICATORS
Though we have taken every conceivable precaution to ensure long lasting and trouble-free operation, occasionally a unit will malfunction. For that, we have made diagnostic simple: each mono block is equipped with two (10 Amperes) fuses designed to protect and monitor the voltage of operating rails (+/-). Each fuse carries its own fault LED indicator that illuminates when the fuse is burnt.
6 . 20HZ-5KHZ FREQUENCY ADJUSTER
Each monaural block features a built-in low pass/high pass variable filter. The fully buffered filter has a range of 20 Hz to 5 kHz.
7 . OUTPUT BINDING POSTS
Gold plated heavy duty binding posts deliver high power output for premium sound quality.

CineNova Grande Power Amplifiers
Rear Panel Overview continued...
8. AC INPUT CONNECTOR
A special heavy duty - 20 Amperes - AC cord is included with every unit. Do not attempt to replace the AC cord with lesser quality AC cords .
Do not remove the ground prong on the AC power cord. This will result in a safety hazard.
9. 12V GROUND
Enables the amplifier to be controlled by another external device with a 12V DC trigger output. Connect the TRIGGER OUTPUT of the external device to the TRIGGER INPUT of the amplifier.
Then, set the TRIGGER switch on the amplifier to ON or DELAY.
The amplifier will automatically respond when the external device is powered on and off.
The Cinénova Grande amplifiers integrate multiple channels of amplification (5 & 7). Each channel (block) is capable of producing up to 750 Watts when driven in 2-ohm load. The enormous amount of power generated by the amplifiers requires a stable 110/220V connection.
Each of the Cinénova Grande amplifiers comes equipped with a
20-Ampere circuit breaker (on the back plates) designed to prevent damages to the unit in case of abnormal AC power surges and deviations. Do not replace the breaker without consulting an Earthquake technician.
To ensure proper operation, make sure that a 20-Ampere circuit is available where the amplifier is going to be plugged. If in doubt, consult with an electrician. Most homes are wired with 20-
Ampere circuits, but there is a chance that the wall receptors are rated only 15 Amperes. After all, proper power supply translates into better performance. CALL AN ELECTRICIAN FOR
ASSISTANCE.

CineNova Grande Power Amplifiers
Special Features
Multiple gigantic heat sinks:
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 and sides- for effective air circulation.
Peak LED indicators:
The Cinénova Grande is equipped with five or seven indicators
-LEDs- on the front panel. They show the operating status of each channel; the LEDs will illuminate when the maximum recommended output is exceeded. If an LED is illuminated the majority of the time, it indicates that the corresponding channel is over-driven (clipped). The input to the channel must be reduced to eliminate distortion and eventually, damages to the amplifier.
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.
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 tolerance.
The multi-layer, glass-epoxy, double sided printed circuit boards
Basic Operation exceed the military stringent requirements by 50%; we use 3 oz copper tracers. Each block hosts twenty 15 Giga-Hz ultra high current Toshiba transistors.
Toroid power transformer:
Each Cinénova contains a monstrous 4KVA high efficiency 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.
EZXS detachable monaural blocks:
Five or seven totally independent mono-block amplifiers (15
Ampere capability) each with its own power supply circuitry and preamplification stage. For ease of service, each block can be individually removed and serviced without the need to dismantle the entire amplifier. EZXS is a trademark of Earthquake Sound
Corporation.

Filter Settings
Each channel - monaural block - of the Cinénova Grande amplifiers comes equipped with a fully buffered variable filter
(range: 20 Hz to 5000 Hz). Once a crossover point is selected, the block can be run in low pass or high pass configuration, simply by a flick of a 3-way switch; the filter can be bypassed by setting the switch to the full range position.

Troubleshooting
Amplifier ON no sound c) Set the crossover switch so that it is centered. Slide it up and down and finally back to the middle position.
d) Confirm that the output wire is connected to the speaker.
e) Unplug and plug the RCA input at the amplifier, you should hear a thump during this process.
WHEN THUMP IS HEARD>>> f) Check your input source signal. Make sure they are connected properly to output, not input. g) Try to change source to make sure that at least one of the sources works.
WHEN NO THUMP IS HEARD>>> h) Check amplifier- speaker connections. i) Make sure the power output terminal is securely connected to the amplifier speakers. NOTE: It is possible that if you have proper connections and you don’t hear sound, the speaker is burnt.
Front LEDs are ON all the time
It is normal when running the amplifier to full power that the LEDs flicker. If you see that the LEDs are on constantly without flickering
(solid orange) it means that the amplifier is clipping. Reduce volume level to prevent damage to the unit.
Turn amplifier ON and circuit breaker shuts down
This can either be a short in amp or poor circuit breaker in the house.
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.
Note:
Visit www.earthquakesound.com for answers to frequently asked questions and additional troubleshooting information.
Trouble Shooting and Maintenance
Humming noise from speakers.
Often humming noise is emanating from equipment that have their ground prong broken.
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 and not connected to any thing.

In an honest effort to provide you with accurate and precise information about the Cinénova Grande amplifier you have just purchased, Earthquake Sound Corporation would like you to be informed and aware of what is considered good, bad and reference in the high end audio industry.
The numbers shown below are the distortion (THD) and the signal to noise (S/N) measurements for your amplifier.
Please note that all measurements are made with 4-ohms dummy loads connected to each individual channel; using the
Audio Precision ATS1 - one of finest test machines available, connected to oscilloscope. This amplifier is designed to handle loads from 2 ohms all the way to 8 ohms, and to provide you with accurate, clean music reproduction.
According to the industry standards, a signal to noise of 90dB to 100dB is considered “very good”, and 100dB as being “excellent”. Every time you increase the S/N by 3dB, you are reducing the noise by a “half level”. With this in mind, please read through the test results of your Cinénova Grande and compare these numbers to other manufacturers numbers.
Only then, you will realize how great of a performer your amplifier is.
