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 to 110 decibels.

Getting Started with the Cinénova Grande

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 circuit breaker for this information.

Amplification Block Plate

Power Plate

1) INPUT SELECTION 2) X-OVER MODE SELECTION

Set the input control to either RCA or XLR. This tells the amp which input type will be used.

3) SPEAKER CONNECTIONS

A pair of binding posts is provided for each channel. These posts accept bare wire, spade lugs & banana type plugs. If bare wire is us e d th e n , st r i p approximately 1/2 inch to 3/4 inch of insulation from the end of each wire and carefully twist the strands of each conductor together. Then insert.

The Cinénova Grande houses 5 or 7 amplification blocks. Each block comes with a 3-way Mode Selection switch. Generally the amplifier Is used in By Pass mode and fed a crossed signal from a processor. Unless otherwise desired, the crossover switch should remain in Bypass position.

4) 12VDC WHEN APPLICABLE

If you plan to power the Cinénova using an external source, then you will need to plug the source into the 12VDC Trigger.

When using this feature the main power switch must remain in the OFF position at all times.

5) PLUG IN POWER CORD 6) TURN ON CIRCUIT BREAKER

Plug the AC power cord into the amp first then

into the wall outlet. Make sure it is firmly connected.

This amp is equipped with a 20 ampere circuit breaker. Once that all tasks have completed then proceed to turn the circuit breaker to the on position.

1. Master Power Switch:

Turns the current to the amplifier ON or OFF manually. When turning on the amplifier via a 12VDC source the switch must be in the OFF position.

Additionally when adding or removing 12VDC connections or any other connections the main power circuit breaker needs to be in the off position. This will help prevent any surges that could damage your products or cause bodily injury.

Cinénova

Grande

2 Peak LED Indicators:.

The Cinénova Grande is equipped with five or seven LED indicators on the front panel that should remain unlit. These LEDs indicate the operating status of each corresponding channel. If an LED or all LEDs remain lit continuously, the amplifier is clipping that channel and the volume should be turned down immediately to prevent damage. Its ok for the LED to flicker but it should never remain on continuously.

3 Handles.

The front handles may be removed. The cover must come off first. You will need a 3mm hex driver for the front mounted screws.

CAUTION: Be sure that what ever is used to mount this amplifier on, is extremely strong and durable.

1. Replaceable Fuses:

Each mono block has two (10 Amperes) 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.

2. RCA Input:

Accepts low-level signal from any source. It takes 1.6V to output the rated power.

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.

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 to be used for different applications.

8 Output Binding Posts:. Gold Plated Speaker

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.

9 Main Circuit Breaker.

The enormous amount of power generated by the amplifiers requires a stable 120 or 240V connection. 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 to the off position.

To ensure proper operation, recommend a dedicated 20amp circuit breaker 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, CONSULT WITH AN ELECTRICIAN.

because a proper power supply

Your amplifier is supplied

6. Variable Crossover 20Hz-5kHz:

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.

7. Fused Fault Indicators:

Each fuse carries its own fault LED indicator that illuminates when the fuse is burnt.

10. 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.

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.

Cinénova Grande Special Features

Technology and Materials

EZXS Detachable Monaural Blocks:

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. EZXS® is a trademark of Earthquake Sound Corporation.

Multiple 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, sides & bottom- for effective air circulation.

Peak LED Indicators:

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 to maintain a stable level of output.

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.

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 600mA for the 5ch Cinénova.

Toroid Power Transformer:

Each Cinénova contains a monstrous 4KVA high 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.

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 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.

Adjusting The Filters

Cinénova Grande 5 or 7 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.

Trouble Shooting and Maintenance

Troubleshooting All Cinénova Models

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.

Humming noise from speakers

Often humming noise is emanating from equipment that have their ground prong broken. To isolate this problem:

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.

Maintenance

The following maintenance should be performed routinely:

! 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.

Circuit Protection

- For Cinénova 7 only

Troubleshooting Cinénova Grande 5 or 7

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.

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.

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.
