Eviter les pièces de fixation • Ne pas utiliser de pièces de fixation ni d’outils non recommandés par le fabricant du matériel car cela risquerait de poser certains dangers.

Warning

Power sources • This equipment should be operated only from the power source indicated on the product. This equipment is intended to be used with a main power system with a grounded (neutral) conductor. The third (grounding) pin is a safety feature, do not attempt to bypass or disable it.

Power disconnection • To remove power from the equipment safely, remove all power cords from the rear of the equipment, or the desktop power module (if detachable), or from the power source receptacle (wall plug).

Power cord protection • Power cords should be routed so that they are not likely to be stepped on or pinched by items placed upon or against them.

Servicing • Refer all servicing to qualified service personnel. There are no user-serviceable parts inside. To prevent the risk of shock, do not attempt to service this equipment yourself because opening or removing covers may expose you to dangerous voltage or other hazards.

Slots and openings • If the equipment has slots or holes in the enclosure, these are provided to prevent overheating of sensitive components inside. These openings must never be blocked by other objects.

Introduction

About this Guide

This guide contains information about the Extron® series of audio power amplifiers: the XPA 2002 two-channel stereo amplifier, the XPA 2002-70V two-channel, 70 V line distribution mono amplifier; the XPA 2002-100V two-channel, 100 V line distribution mono amplifier; the XPA 2003C-70V three-channel, stereo 4-ohm and 8-ohm, mono 70 V line distribution amplifier; the XPA 2003C-100V three-channel, stereo 4-ohm, 8-ohm, mono 100 V line distribution amplifier; and the XPA 2004 four-channel stereo amplifier.

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

zzXPA 2002 outputs stereo 200 watts rms per channel (4-ohm speakers) or 100 watts rms per channel (8-ohm speakers) on channels 1 and 2. Output is 400 watts bridged mode mono (8-ohm speaker).

zzXPA 2002-70V outputs 200 watts rms per channel on channels 1 and 2 for 70 V systems.

zzXPA 2002-100V outputs 200 watts rms per channel on channels 1 and 2 for100 V systems.

zzXPA 2003C-70V outputs 200 watts per channel (4-ohm speakers) or 100 watts per channel (8-ohm speakers) on channels 1 and 2, and 200 watts (70 V line, mono) on channel 3.

zzXPA 2003C-100V outputs 200 watts per channel (4-ohm speakers) or 100 watts per channel (8-ohm speakers) on channels 1 and 2, and 200 watts (100 V line, mono) on channel 3.

zzXPA 2004 outputs stereo 200 watts per channel (4-ohm speakers) or 100 watts per channel (8-ohm speakers) on channels 1, 2, 3, and 4. Output is 400 watts per bridge in bridged mono (8-ohm speakers) on bridge A (channels 1 and 2) and bridge B (channels 3 and 4).

Terms Used in this Guide

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

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

zz Display limiter/protect status when audio clipping or amplifier malfunction occurs. zz 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 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 2002 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 level 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.
