About this Guide

This guide describes the XPA U 1004 SB and XPA U 2002 SB Half Rack Four-Channel/Two-
Channel audio power amplifiers and discusses how to install, configure, and operate them.
In this guide, the terms "unit", "amplifier", and "power amplifier" refer to the
XPA U 1004 SB and XPA U 2002 SB.
About the XPA U 1004 SB and XPA U 2002 SB
The Extron XPA U 1004 SB and XPA U 2002 SB are ENERGY STAR qualified four- and
two-channel audio power amplifiers with flexible channel pairs that can drive 8 ohm, 4 ohm,
70 volt, or 100 volt loads. The XPA U 1004 SB's two individually bridgeable pairs can deliver
two 100 watt channels into low-impedance systems or one 200 watt channel into low- or
high-impedance systems. The XPA U 2002 SB's bridgeable output pair can deliver two
200 watt channels into low-impedance systems or one 400 watt channel into low- or high-
impedance systems.
Output mode selection is made via a rear panel rotary switch for quick and easy setup.
The convection-cooled, plenum-rated enclosures of the XPA U 1004 SB and XPA U 2002
SB don't require empty rack spaces for ventilation and include rack mount hardware. They
feature a highly efficient advanced Class D amplifier design with defeatable auto standby,
fast wake up from standby, and patented Extron CDRS (Class D Ripple Suppression)
technology. Remote volume and mute control is possible per channel pair from Extron VCM,
VC, and select MediaLink controllers.
