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

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.
Cinénova Grande Power Amplifiers
Cinénova Grande 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
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.

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

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.
To ensure proper operation,
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,
CONSULT WITH AN ELECTRICIAN.
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 to the off position.
we
recommend a dedicated 20amp circuit
breaker
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.
10. AC Input Connector
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.
