About this Guide

This guide describes the XPA U 1004 SB and XPA U 2002 SB Half Rack Four-Channel/Two­Channel 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 high­impedance 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.

XPA U 1004 SB and XPA U 2002 SB • Introduction 1

Features

• Selectable output modes per channel pair:

• XPA U 1004 SB

• Two 100 watt channels into 8 ohms or 4 ohms

• One 200 watt bridged channel into 70V or 100V, with or without HPF

• One 200 watt bridged channel into 8 ohms or 16 ohms

• — Allows this amplifier model to be used in a wide variety of system configurations

• XPA U 2002 SB

• Two 200 watt channels into 8 ohms or 4 ohms

• One 400 watt bridged channel into 70V or 100V, with or without HPF

• One 400 watt bridged channel into 8 ohms or 16 ohms

• — Allows this amplifier model to be used in a wide variety of system configurations

• ENERGY STAR

®

qualified amplifiers — The XPA U 1004 SB and the XPA U 2002 SB

are ENERGY STAR qualified and energy efficient amplifiers, conserving energy and reducing
costs.

• Extron Patented CDRS (Class D Ripple Suppression) Technology — CDRS is an

Extron pantented technology providing a smooth and clean audio waveform, and improving
signal fidelity over Class D amplifier designs.

• CDRS eliminates the high frequency switching ripple characteristics of Class D

amplifiers, a source of RF emissions which can interfere with sensitive AV equipment
like wireless mircophones.

• Convection cooled and fanless operation ‑ can be stacked without extra rack space for

• ventilation — The XPA U 1004 SB and the XPA U 2002 SB do not have internal fans or

vents for cooling, ensuring quiet reliable operation. The units generate substantially less
heat than conventional power amplifiers, making the XPA Ultra Series ideal for rack-mount
applications where space is limited.

• See Rack Mounting Ventilation Recommendations on page7.

• Defeatable auto-standby with fast wake up — The amplifiers meet ENERGY STAR

qualification requirements with an auto-standby feature that automatically places the
units into standby after 25 minutes of in activity; thereby dramatically reducing power
consumption. The XPA U 1004 SB and XPA U 2002 SB quickly return to full power in less
100 ms upon signal detection, with minimal inrush current. Auto-standby can be disabled if
required.

• UL 2043 Plenum rated when used with the optional Flexible Conduit Adapter Kit/

AV equipment — The XPA U 1004 SB and XPA U 2002 SB amplifiers meet UL 2043
when installed with the Flexible Conduit Adapter Kit, part # 70-228-02. The amplifiers must
meet this requirement for heat and smoke release for installation within a plenum airspace.
Above-the-ceiling placement conceals the amplifier to prevent theft, and it is convenient for
installing when space inside the room is limited.

• Remote volume and mute control per channel pair — With Extron VCM, VC, and

select MediaLink controllers.

• All rated watts are usable with all channels driven — With a XPA Ultra, designs can

utilize 100% of the rated power.

• Professional grade signal-to-noise and THD+N performance — The XPA U 1004 SB

and the XPA U 2002 SB both deliver professional grade performance, featuring 100 dB
signal-to-noise ratio and THD+N of less than 0.1%.
