Introduction

About this Manual

This manual contains information about the Extron XTRA Series of power amplifiers.

• XPA 1002 two-channel stereo audio power amplifier

• XPA 1002 Plus two-channel stereo audio power amplifier

• XPA 1002-70V two-channel audio power amplifier

• XPA 1002-100V two-channel audio power amplifier

• XPA 2001-70V mono audio power amplifier

• XPA 2001-100V mono audio power amplifier

Terms Used in this Manual

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

to all of the XPA models. “XPA 1002 series” refers to the XPA 1002, XPA 1002 Plus,

XPA 1002-70V, and XPA 1002-100V products. ”XPA2001” refers to both the XPA2001-70V

and the XPA2001-100V products.

Features

• Inputs — Balanced or unbalanced stereo or mono on a 3.5 mm, 5-pole captive screw

connector.

• Speaker outputs — Screw-lock, 5 mm captive screw connectors enable simple,

secure connections with 22 AWG to 12 AWG speaker cables.

• Continuous power output for larger rooms —

• XPA1002: 60watts rms per channel at 8 ohms; 100watts rms per channel at

4ohms

• XPA 1002 Plus: 100 watts rms per channel at 4 and 8 ohms

• XPA 1002-70V: 100 watts rms per channel for 70 volt speaker systems

• XPA 1002-100V: 100 watts rms per channel for 100 volt speaker systems

• XPA2001-70V: 200watts rms for 70volt speaker systems

• XPA2001-100V: 200watts rms for 100volt speaker systems

• Professional-grade amplifier design —

• The XPA 1002 and XPA 1002 Plus features less than 0.05% total harmonic

distortion plus noise, and better than 105 dB signal-to-noise ratio.

• The XPA 1002-70V, XPA 1002-100V, and XPA 2001 series feature less than 0.1%

total harmonic distortion plus noise, and better than 100 dB signal to noise ratio.

• ENERGY STAR® qualified amplifier — The XTRA Series of amplifiers are energy

efficient products that conserve energy and reduce operating costs.

XTRA Series Half-Rack Audio Power Amplifiers • Introduction 2

• Highly efficient Class D amplifier design — The XTRA Series of amplifiers generate

substantially less heat than conventional amplifier designs, making them ideal for

installation in equipment racks and lecterns with very limited ventilation. They consume

10watts when idle and less than 1 watt in standby mode.

• Extron patented CDRS — Class D ripple suppression — A patented, exclusive

technology from Extron that eliminates the high frequency switching ripple and EMI

emissions found in typical Class D amplifiers. CDRS enables Extron power amplifiers to

be situated near wireless AV devices without RF interference.

• Convection cooled — The XTRA Series of amplifiers are convection cooled without

the need for fans, ensuring quiet, reliable operation.

• Ultra-low inrush current — no need for power sequencing — Allows many XTRA

series amplifiers to be powered on simultaneously without overloading power circuits.

This eliminates the need for power sequencing.

• Flexible Conduit Adapter Kit — Suitable for use in other environmental air space in

accordance with section 300.22, (C) of the National Electrical Code only when used

with optional Flexible Conduit Adapter Kit.

• Auto-standby with fast power-up — The amplifiers automatically enter into a

standby mode after 25 minutes of inactivity, + or - 5 minutes, dramatically reducing

power consumption. They quickly return to full power status upon signal detection.

• Rear panel attenuation (level) controls — Provide attenuation of input signals for

setting proper audio system gain staging as well as two-zone applications. They are

located on the rear panel to prevent unauthorized or accidental tampering of the level

adjustments.

• Multiple protection circuits — Activates during excessive clipping, output shorts,

thermal overload, or DC faults to prevent damage to the amplifier and speakers.

• Remote standby port — Enables the amplifiers to be remotely powered down when

not in use, reducing operating cost.

• Remote volume and mute control port — This port allows the XPA 1002,

XPA 1002 Plus, and the XPA 2001 series to be remotely controlled using the optional

Extron VCM100 Series volume and mute or VC50 volume controllers.

• Bridgeable outputs — The power output of the XPA 1002 and XPA 1002 Plus can

be effectively doubled by bridging the output. A mono source is wired to both the left

and right input while the output is wired for bridged operation. Bridging allows power to

be output at 200 watts into 8 ohms. The minimum load impedance when bridging is 8

ohms (see the Bridged Mono Output (XPA 1002, XPA 1002 Plus) wiring instructions

on page20).

• Front and rear-mounted signal and protection indication LEDs — Provide

convenient indication of amplifier operation from both sides of an equipment rack.

• Internal international power supply — The 100-240 VAC, 50-60Hz universal power

supply provides worldwide power compatibility.
