XTRA Full Rack Power Amplifier Series • Introduction 1

Introduction

About this User Guide

This user guide contains information about the Extron series of full rack width audio power

amplifiers.

The Extron XTRA™ Series is a family of 1U convection cooled power amplifiers with mono,

stereo, and multi-channel outputs. These professional grade amplifiers deliver from 200

to 800 watts of continuous output power and are available for low and high impedance

applications. Each model offers professional grade signal-to-noise ratio and THD+N

performance.

XTRA Series amplifiers are ENERGY STAR® qualified amplifiers with an Extron exclusive,

highly efficient, advanced Class D amplifier design. They also feature patented CDRS™ -

Class D Ripple Suppression technology that provides a smooth, clean audio waveform and

an improvement in signal fidelity over conventional Class D amplifiers. XTRA Series amplifiers

are one quarter to one half the size of comparable amplifiers, conserving rack space. The

Extron exclusive, high efficiency design generates very little heat and allows the amplifiers to

be convection cooled.

The XPA series of amplifiers are full-rack width models with different power outputs:

• The XPA 2002-70V two channel amplifier delivers 200 watts rms per channel for 70 volt

high impedance speaker systems.

• The XPA 2002-100V two channel amplifier delivers 200 watts rms per channel for

100 volt high impedance speaker systems.

• The XPA 2003C-70V three channel amplifier delivers two channels of 200 watts rms into

4 ohms or 100 watts rms into 8 ohms. It delivers a third channel with 200 watts rms into

a 70 volt line for high impedance speaker systems.

• The XPA 2003C-100V three channel amplifier delivers two channels of 200 watts rms

into 4 ohms or 100 watts rms into 8 ohms. It delivers a third channel with 200 watts rms

into a 100 volt line for high impedance speaker systems.

• The XPA 2004 four channel amplifier delivers 200 watts rms per channel into 4 ohms or

100 watts rms per channel into 8 ohms. It features a bridged mode that provides two

channels of 400 watts rms output into 8 ohms.

• The XPA 4002 two channel low impedance amplifier delivers 400 watts rms per channel

into 4 ohms or 200 watts rms per channel into 8 ohms. It features a bridged mode that

provides a single 800 watt output into 8 ohms.

• The XPA 4002-70V two channel amplifier delivers 400 watts rms per channel for 70 volt

high impedance speaker systems.

Terms Used in this User Guide

The terms “amplifier” and “power amplifier” are used interchangeably in this guide to refer to

each model.

XTRA Full Rack Power Amplifier Series • Introduction 2

Features

Extron Patented Class D Ripple Steering (CDRS™) technology — CDRS is

an Extron patented technology that provides a smooth, clean audio waveform and an

improvement in signal fidelity over conventional Class D amplifier designs. CDRS eliminates

the high frequency switching ripple characteristic of Class D amplifiers, a source of RF

emissions, which can interfere with sensitive A/V equipment such as wireless microphones.

Professional grade signal-to-noise and THD performance — Delivers professional

grade performance with 100 dB signal-to-noise ratio and THD of less than 0.1%.

Front and rear panel LED indicators —

• Display limiter/protect status when audio limiting or amplifier malfunction occurs.

• Indicate the presence of input signals.

Audio level adjustment — Potentiometers to adjust the audio level from =(full attenuation)

to 0 dB (no attenuation).

IEC power switch — Rear panel IEC rocker power switch.

1U full rack enclosure — The capability to deliver full-sized amplifier power in one half the

size of many comparable power amplifiers.

High pass filtering — A high pass filter (XPA 2002-70V, XPA 2002-100V,

XPA 4002-70V, XPA 2003C-70V, and XPA 2003C-100V only) toggle switch prevents

saturation of speaker input transformers by low frequency signals. Saturation can result in

severe distortion of the speaker output signal.

Bridged output mode — The XPA 2004 has a toggle switch to input channels 1 and 3 and

output each input as a single bridged output channel at twice the power of a single channel.

Input 1 is output over the positive terminals of output channels 1 and 2. Input 3 is output

over the positive terminals of output channels 3 and 4.

The XPA 4002 has a toggle switch to input channel 1 and output a single bridged output

channel at twice the power using the positive terminals of channels 1 and 2.

Convection cooled, fanless operation — Ensuring quiet reliable operation. All models

generate substantially less heat than similar power amplifer designs.

Automatic clip limiter — Detects actual onset of clipping by comparing input and output

waveforms. Gain is automatically reduced with a slow attack and fast release to eliminate

clipping. This advanced limiter design protects the speakers from clipping distortion and

offers superior sonic characteristics compared to limiters that use signal compression.

Rear panel recessed, detented attenuation controls — Provide attenuation of input

signals for adjusting audio system gain staging as well as multi-zone applications. They are

located on the rear panel to prevent users from tampering with level adjustments.

Remote standby — Standby control that remotely shuts off all amplifier output while power

remains active at the amplifier.

Power factor correction — Features power factor correction technology that smoothes out

the high peak currents of the current draw of the amplifier, thus minimizing the presence of

high frequency harmonics on the AC power line, and therefore preventing audible artifacts

from being transmitted to other audio equipment in the system.

Class 2 wiring — The outputs from the amplifiers support Class 2 wiring that meets UL

requirements.

ENERGY STAR®qualified — All models are ENERGY STAR qualified amplifiers that

conserve energy and reduce costs.
