Power, Control & Intensity

The ECLIPSE Premium Amplifiers are 100%

ECLIPSE, created with our dedication to quality

construction, sonic excellence and flat-out

performance. No current limiting and completely

unregulated power supplies guarantee a neutral,

clean sound quality with virtually unlimited

dynamic power on demand.

Separated Power Supply and Signal

Amplifier Sections

ECLIPSE 34230 high-quality audio systems rely

on separate and independent amplifier power

supply and signal sections to ensure a stable

source of power and clear signal. The benefit of

having separate power and driver stages are even

greater in a car audio environment, with its

significant electrical current, vibrations and

various sources of distortion. The ECLIPSE 34230

delivers generous power without noise.

Interference between the power and driver stages

such as switching distortion and radiated noise are

eliminated. The result is sonic purity and effortless

power.

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.

Massive Bus Bars

Look for the sizable metal bars used at the power

supply connector of 34230. These bus bars allow

the flow of high current to the PC board more

efficiently without potential meltdown of solder

traces or the added resistance presented by more

parts. Passing all that current through a bus bar

rather than a circuit board solder trace keeps

unwanted heat and resistance to a minimum. The

secondary signal circuit board also has input

power connections to the main PC board using the

same copper bus bar blocks, which helps to keep

the heat out of the delicate, sensitive electronic

components of the amplifier. Less heat and cleaner

sound make for better performance.

High Voltage Input

Even the best-engineered amplifiers often overlook

the obvious. ECLIPSE has engineered very high

input voltage capabilities into the new amplifiers

so that you can take advantage of the full

performance that your high signal voltage headunit

output offers. Without high voltage input

capability, an amplifier will clip prematurely and

create excessive heat in the speaker. Able to handle

input signals of up to 8 volts, these amplifiers are

compatible with virtually any signal source voltage

output used in car audio today and easily cope

with competition-use demands.

ChannelFlex Crossover

The built-in ChannelFlex crossover is designed

with audio quality, flexibility, and simplicity of

system design and installation in mind. This is not

just an ordinary built in crossover though. There

are effectively two separate and distinct crossovers

with a variable subsonic filter in the 34230 and

33250 and switchable slope control for the 33250

and 33230. The switchable slope feature allows for

more precise control of bandwidth limited output

power, which means more sonic accuracy in

subwoofers, midbass drivers, and midrange

drivers without distortion. Since distortion is a

major contributor to premature speaker failures,

the variable subsonic filter in the 34230 and 33250

and switchable slope control for the 33250 and

33230 will make speakers last longer and sound

audibly better.

Pre-Amp Outputs

The 34230, and 33250 all feature crossover pre-

amp level outputs, which make adding additional

amplifiers in the system a simple and

straightforward process. 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.

Intelligent 7-Way Discrete Protection

Circuitry

Seven-way protection circuitry protects the

amplifiers from accidental misconnections or short

circuits in the audio system. There is thermal

protection (up to 100°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

discrete from the audio signal path, so the audio

signal never passes through protection

components, keeping the audio signal free of

interference, coloration or noise.

Noise Reduction with Low Distortion &

Ultralow Negative Feedback

ECLIPSE amplifiers use very high-quality amp

devices which are inherently less noisy than those

conventionally used by other manufactureres. The

traditional method of reducing distortion is to

“feedback” out-of-phase distortion into the audio

signal. The idea is that two out-of-phase signals

should cancel each other. This does work, but at

the expense of an appealing, open sound, usually

causing a closed-in type of sound devoid of

warmth.The higher-quality components in

ECLIPSE amplifiers and their advanced circuits

make such “bandaid” fixes like too much NFB

wholly unnecessary.

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 to

significantly increase absolute listening pleasure

in your vehicle.

High-Current, High-Speed Output

Devices

The output devices are capable of generating high

current at high speed. This improves both

frequency response and amplifier damping which

helps control the mechanical movement of the

speaker cone.

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.

Audiophile-Grade Component Selection

High-quality components and parts designed

exclusively for audio applications are employed for

a difference that is easily heard.
