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.
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.
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% 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.

Power, control and intensity.
Preamp outputs.
High-current, high-speed output
devices.
The ECLIPSE Premium Amplifiers feature no
current limiting and completely unregulated power
supplies for a neutral, clean sound quality with
virtually unlimited dynamic power on demand.
The 34230 also features crossover preamp level
outputs, for adding additional amplifiers. Signal
purity is maintained throughout due to common
signal reference grounds and high signal voltages.
It perfectly complements the simplicity of total
system design using ECLIPSE amplifiers.
The output devices are capable of generating high
current at high speed to improve both frequency
response and amplifier damping.
Separate power supply and signal
amplifier sections.
High-efficiency, high-energy MOSFET
power supply.
The ECLIPSE power supply uses current draw
from the car’s electrical system more efficiently
to produce higher power.
Intelligent 7-way discrete protection
circuitry.
The ECLIPSE 34230 has separate and independent
amplifier power supply and signal sections. The
benefit of having separate power and driver stages
are greater in a car audio environment, with its
significant electrical current, vibrations and
various sources of distortion. The ECLIPSE 34230
has no noise interference between the power and
driver stages such as switching distortion and
radiated noise for sonic purity and effortless
power.
Seven-way protection circuitry protects the
amplifiers from accidental misconnections or short
circuits in the audio system. There is thermal
protection (up to 90°C), DC offset, protection
against excessive current on the output side,
voltage output overload, excessive current in the
power supply, reverse polarity power input and
shorted speaker leads. A servo system monitors
each of these circuits and measures them against a
reference. If a condition is determined to be
outside of reference tolerances, the amplifier enters
a protection mode, preventing damage to the amp
and audio system. The protection circuitry is
never in the audio signal path, keeping the audio
signal free of interference, coloration or noise.
Double-sided printed circuit boards.
ECLIPSE Premium Amplifiers employ 70-micron
copper circuit board traces (twice the thickness of
a conventional copper trace) for superior sound
quality. This technology provides lower distortion
and improved low frequency performance.
Audiophile-grade component selection.
High-quality components and parts designed
exclusively for quality audio applications are
employed for a difference that is easily heard.
Symmetrical layout.
The ECLIPSE 34230 utilizes a symmetrical
component layout to achieve superior channel
separation. The right and left channels are
physically isolated to eliminate intermodulation
and achieve excellent separation, resulting in
vastly improved system imaging capability.
Noise reduction with low distortion and
ultralow negative feedback.
Massive bus bars.
ECLIPSE amplifiers use very high-quality amp
devices and the circuit makes minimal use of
negative feedback for better sound. The higher-
quality components in ECLIPSE amplifiers and
their advanced circuits make “bandaid” fixes like
too much NFB unnecessary.
The massive bus bars allow high current to flow to
the PC board more efficiently and keeps unwanted
heat and resistance to a minimum.
High voltage input.
ECLIPSE engineered very high input voltage
capabilities into its amplifiers to take advantage of
the high signal voltage output from the head unit.
Able to handle input signals of up to 8 volts, these
amplifiers easily cope with competition-use
demands.
ChannelFlex Crossover.
There are effectively two separate and distinct
crossovers with a variable subsonic filter in the
34230 and switchable slope control for the
PA4212. The selectable slope allows for more
precise control of bandwidth limited output power,
which means more sonic accuracy in subwoofers,
midbass drivers, and midrange drivers without
distortion. The variable subsonic filter in the
34230 and switchable slope control for the
PA4212 will make speakers last longer and sound
audibly better.
