Cinénova Grande Power Amplifiers

Cinénova Grande Special Features

Technology and Materials Special Features

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.
