Earthquake - G5B - Cinenova Grande 5 - Power Amplifier

Like the best things in life, Earthquake's Cinénova Grande 5 is created with love for detail, passion for strength and respect for grace. The Cinénova Grande 5 conveys audio without interpretation, coloring or compression - True to life.

Immaculate sound quality matched with massive power and performance places Cinénova Grande at the top in the heavyweight class of high end multi-channel amplifiers. With 2000 watts dynamic and 1000 watts continuous power per channel, Cinénova Grande is the world's most powerful multi-channel amplifier. It is ideal for both the two-channel high-end enthusiast who wants the benefits of bi-amping, and the serious home theater owner who demands unlimited power even during the most explosive movie sequences.

Cinénova Grande is comprised of individual amplifier blocks named Alpha One. The 5 Alpha One module blocks work independently of each other – each is a 1000W power amplifier itself. Each Alpha One has a 15A supply and is equipped with its own preamplifier and power supply circuits (electrolytes, rectifier, etc.). Alpha One is equipped with 12 ultra-fast 15GHz, 30A customized Toshiba transistors. This armament allows 1000W continuous power and 2000W transient response.

Cinénova Grande is equipped with a monstrous 4000VA toroidal transformer. Besides its vast mass, there are several things that distinguish it from other audio transformers. It is based on a core of pure ferrite giving the transformer a very high power density and stiffness compared to typical iron cores. The transformer is wound of 99.99% oxygen free copper of 12 gauge thickness. The use of oxygen-free copper as winding material increases the transformer's efficiency and stiffness significantly. The combination of a core of pure ferrite and windings of oxygen free copper elevates transformer power efficiency. This means that only a fraction of flow-through current is converted into heat.

The Cinénova Grande 5 built-in AC line conditioner technology makes it unaffected by noise from the power grid. This ensures that DC content in the mains is not dissipated as heat and hum in the amplifier's main transformer. Many have probably seen how the activation of a refrigerator compressor can be heard throughout the speakers and how electronic transformers in halogen lights can create noise on the power grid.

Each Alpha One power module block has an immense heat sink of extruded and anodized aluminum. With a heat sink surface area of more than 3300 cm2. To put this in perspective, it corresponds to a flat piece of aluminum of 57 x 57 cm. A large surface area is essential for the heat sinks ability to dissipate the heat from the large transistors. A large surface area alone is not enough to constitute an effective cooling system. The cooling system must be designed so that the natural convection (the characteristic that hot air rises) is utilized optimally.

Cinénova Grande is able to accept both balanced XLR connections and general unbalanced  RCA signals. Traditionally, RCA and XLR inputs are mounted parallel to the same signal path and both inputs are active all the time. That means using the XLR inputs the  RCA input acts as a small outdoor antenna and adds noise to the signal path.  Cinénova Grande has a switch which disconnects the unused input. This ensures a closed signal path free from extraneous noise which is essential for a true balanced design to operate optimally.
