SIRCL2 SIRIUS Satellite Radio Receiver Package

This package includes Clarion’s SIRCL1 receiver and

SA150 Generation II antenna. The receiver can be

controlled using either a CeNET-equipped source unit

or by using the DSC920S.

Features:

• CeNET Interface for Direct Operation by all SIRIUS-

Ready Clarion Source Units

• L/R RCA Line Level Outputs for Easy Connection to

FM200 FM Modulator, as Well as Any Line-Level

Input Devices

• CeNET Pass-Through for Connection of CD Changers

and Any Other Clarion Products.

Clarion’s Three-Tier Approach

Clarion’s three-tier amplifier line was constructed to address all power needs. All offer high power. The difference is in the

approach. The line starts with the APA4300HX, an amplifier designed to compliment Clarion’s DRZ9255 both in perform-

ance and cosmetics. As you will see, this feature-laden amplifier is what high-end audio is all about.

The line continues with the APA4320 and APA2160. These two amplifiers are as versatile as they come — both in features

and in cosmetic design. Features include a Bass Extender, high- and low-pass crossovers, Mixed Mode Operation, Speaker

Level Inputs, and much more. But the key to these two amplifiers is their compact design — making them the perfect fit

for space-limited installations.

Rounding out Clarion’s amplifier line are the APA2001, APA450 and APA250. The motto for these three amplifiers is “Power

With a Conscience.” Why? Offering great power output, these three amplifiers are also priced affordably. Bottom line, if your

building a system for a budget-minded customer, these are the amplifiers you need to look to.

Amplifiers and Processors

Audiophile-Grade Power

From its exterior color scheme to its refined circuit

layout, stable power supply and high-capacity output

stage, it’s clear the APA4300HX was intended for

the serious audio buff. With all channels containing high-

and low-pass filters with variable crossover frequencies

(50Hz to 20Hz), the amplifier also allows for easy

system expansion.

The amplifier also offers an input signal mixer function,

which uses a bridge to mix the left and right channels.

From there, the amplifier outputs both signals via one

channel. This is especially useful when driving a mono

subwoofer over the amplifier’s integrated low-pass filter.

The APA4300HX also incorporates a highly efficient cool-

ing system. This consists of a thermally-balanced cooling

tunnel and thermally-operated fan. Coupled with the large

cooling surface on the amplifier’s housing — which incor-

porates large tunnel-shaped heat sinks — the amplifier

guarantees excellent and safe operation at the output

stages, regardless of the loads.

Current Feedback Amplification Circuit

The unique circuit design maximizes the potential of the

amplifier, allowing it to realize even ultra-high frequency

levels of 100kHz. This wideband, high-speed amplification

circuit also ensures stable phase characteristics and

response. This circuit layout also adds music dimension,

and provides additional harmonic elements while main-

taining the main frequency element. The design also

prevents phase shifts of high-range frequencies from

becoming audible.
