Eclipse - Fujitsu Ten DA7232 manual DA7122, Features

ECLIPSE’s dedicated subwoofer amplifiers use Class D amplifier technology and topology to produce the greatest efficiency of any class of amplifier operation. The DA7232 2 channel and DA7122 1 channel Class D subwoofer amplifiers effortlessly drive any subwoofer system to produce awesome low frequencies both heard and felt. ECLIPSE combined well-known specialist audio manufacturer Bang&Olufsen’s amplification modules with proprietary no-compromise audio technologies to create the ultimate subwoofer amplifiers.

Class D optimized for low frequency reproduction.

Quality construction throughout.

Built to the same exacting standards as other models in the Premium Amplifer Series, the DA7232 and DA7122 boast high-end amplifier circuits and construction techniques such as high-efficiency high-energy isolated power supplies, symmetrical layout, high input overload, discrete protection and audiophile- grade components. This uncommon level of attention to build and quality in dedicated subwoofer amplifiers is what optimizes these amplifiers for use in the most demanding systems.

Features

•Maximum power output of 2000W (both channels) into a 2 ohm load.

•Peak output current in excess of 50A for virtually limitless power.

•Immense 120dBA dynamic range for effortless reproduction of the lowest frequencies.

•Built-in protection against over and under- voltage conditions.

•Additional protection for amplifier and speakers as well as soft clipping and soft start-up functions.

•Balanced inputs and outputs.

A class D or Pulse Modulation Amplifier (PMA) switching amplifier design makes use of its output devices (usually MOSFETS) to pulse on and off at very high frequencies with a continuously changing duty cycle. The result is an average output level which is then converted to an audio signal by the averaging action of the speakers. The efficiency of Class D amplifiers reaches over 90% with significantly less heat generation than conventional amplifiers, allowing smaller dimensions while generating significant power and making them inherently ideal for reproducing low frequencies. And because a dedicated subwoofer amplifier only reproduces a limited bandwidth, the DA7232 and DA7122 exploit all the advantages of Class D amplification to the maximum. ECLIPSE also uses a new and innovative Class D/PMA modulation method with higher performance than conventional Class D amplification.

Compact but extremely powerful.

With compact footprints, the DA7232 amplifier and DA7122 1 channel amplifier easily output 2000W per channel with vanishingly low total harmonic distortion and a high S/N ratio. The high efficiency of these amplifiers makes any forced cooling unnecessary, eliminating fans and heavy heat sinks even when operating continuously at high power and driving low impedance speaker loads.

Integrates seamlessly with the total system.

These amplifiers incorporate a flexible onboard crossover section with variable subsonic and low pass filters for optimally balanced and seamless sound between subwoofers and main speakers.
