Today mobile audio systems’ power

amplification requirements often surpass

those of home high-end systems as the

listening environments are so different

and in the case of vehicles, so much more

demanding and noisy. To address such

specific needs, ECLIPSE introduces a

dedicated subwoofer amplifier meant for

use in the finest systems. Making use of

an amplifier technology and topology

known as Class D which produces the

greatest efficiency of any class of

amplifier operation, the DA7232 CYCLOPS

PowerHouse will effortlessly drive any

subwoofer system to produce the most

awesome low frequencies heard and felt,

yet seamlessly blend with the rest of the

system. ECLIPSE combines well-known

specialist audio manufacturer

Bang&Olufsen ICEpower’s state-of-the-art

1000A audio amplification module with its

proprietary no-compromise audio

technologies to create the ultimate

subwoofer amplifier.

Class D Optimized for Low Frequency

Reproduction

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% and allows them to generate much less heat

than conventional amplifiers. A Class D amplifier

can therefore be smaller and draw less current all

the while putting out significant power. And

because a dedicated subwoofer amplifier only has

to reproduce a limited bandwidth, i.e. just the low

frequencies, the CYCLOPS can exploit all the

advantages of Class D amplification to the

maximum. ECLIPSE makes use of a new and

innovative Class D/PMA modulation method for

higher performance than conventional Class D

amplification. That’s why Class D amplifiers are

found in most of the powered subwoofers used in

home high-end audio and home theater systems

because they are inherently ideal for reproducing

low frequencies.

Compact but So Powerful

With its compact footprint, the DA7232 CYCLOPS

PowerHouse manages to output 2000W per

channel with vanishingly low total harmonic

distortion and a high S/N ratio. Its high efficiency

makes any forced cooling unnecessary, also

eliminating large and heavy heat sinks even

operating continuously at high power and driving

low impedance loads.

Integrates Seamlessly with Total

System

One measure of an extraordinary subwoofer

system is how it can blend with the rest of the

system speakers. CYCLOPS incorporates a flexible

onboard crossover section incorporating a

subsonic filter as well as a low pass filter. Both

filters are variable to allow setting an optimally

balanced sound between the subwoofers and main

speakers.

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.

Quality Construction Throughout

Built to the same exacting standards as other

models in the Premium Amplifer Series, the

CYCLOPS also boasts high-end amplifier circuit

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 makes

CYCLOPS ideal for use in the most demanding

systems.
