About this User Guide

This user guide contains information about the Extron XTRA 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 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.

Extron Patented CDRS™ - Class D Ripple Suppression — 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 AV equipment such as wireless microphones.
