Introduction This section provides the overview information about this product and guide including: zz About this Guide zz Features zz Application Examples About this Guide This guide contains information about the Extron® XTRA™ Series, XPA 1002 two-channel stereo, XPA 2001-70V and XPA 2001‑100V mono, audio power amplifiers. 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.
zz 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. zz 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, part number 70-228-02.
Application Examples The following illustrations are application examples for the XPA 1002 and the XPA 2001.

Installation and Operation This section provides information on how to connect and operate the XTRA series power amplifier. zz Mounting the Amplifer zz Front Panel Features and Operation zz Rear Panel Features and Operation Mounting the Amplifier The XPA 1002 and XPA 2001 audio amplifiers can be set on a table, mounted on a rack shelf, or mounted in the plenum space above a ceiling-mounted projector (see “Mounting the XPA 1002 and XPA 2001” on page 17 for detailed mounting instructions and examples).
b Over Temp indicator LED — This LED lights red when the amplifier exceeds the recommended ambient temperature for optimal lifetime. The LED will turn off after the amplifier has cooled down sufficiently. Should the LED light, check the following: Ñ zz Verify the placement of the amplifier allows for adequate ventilation and airflow. zz Avoid placing other equipment on top of the amplifier. zz Verify the operating temperature is within the specified range.

É Limiter/Protect indicator LED — This LED (representing the output channel) lights red under four circumstances: zz When the output wiring is shorted together zz When audio clipping occurs, the LED blinks once per clip occurrence. zz When the amplifier overheats, the LED is lit. The LED is not lit after the amplifier cools down and recovers from the overheated condition. zz When DC output is detected, the amplifier is malfunctioning and the LED is lit.
à Balanced or unbalanced stereo audio input connector — Wire the 3.5 mm 5-pin captive screw connector for balanced or unbalanced input. R R L Tip Sleeve Tip Ring Sleeves Tip Ring L Tip Sleeve Balanced Stereo Input Unbalanced Stereo Input Do not tin the wires! NOTE: â The XPA 1002 output power can be effectively doubled by using only one input channel and bridging the output. The XPA 1002 will output 200 watts @ 8 ohms or 120 watts @ 16 ohms in bridged mode.
f Remote control connector — The 3.5 mm 5-pole captive screw receptacle is used to remotely control two functions through contact closure (see the following circuit diagram). zz Pins 1, 2, and 3 control volume by varying the DC voltage from 0 V (full attenuation) to 10 V (maximum volume) with full muting in effect when pin 2 is connected to ground (pin 3). Use the included 3-pole captive screw connector (see “Remote Volume Control” on page 11 ).
To wire the stereo output connector: 1. Strip and insert the speaker wires into the connector and tighten the captive screws. Be sure to observe the correct polarity. Do not tin the wires! 2. Insert the wired connector into the amplifier output and secure the locking screws on either side. UT TP 2 OU 1 ç Mono audio output connector — Marked “+” and “–”, wire the included 2-pole, 5 mm screw lock captive screw connector for mono audio. See the steps starting below.
2. Insert the wired connector into the amplifier output and secure the locking screws on either side. UT TP OU70V h High pass filter toggle switch — Use a small screwdriver to toggle this recessed two-position toggle switch that alternates between Off and 80 Hz. Setting the switch to 80 Hz prevents the saturation of 70 V/100 V speaker input transformers by low frequency signals. Saturation may result in undesired overheating of the speaker transformers.
Bridged Mono Output The power output of the XPA 1002 can be effectively doubled by bridging the output. Bridging allows power to be output in mono at 200 watts @ 8 ohms or 120 watts @ 16 ohms. NOTE: The bridging instructions that follow apply only to the XPA 1002 model. Minimum load impedance when bridging is 8 ohms. To bridge the output channels refer to figure 8: 1. Unplug the IEC power cord from the power amplifier. 2. Wire the output as shown.

Mounting the XPA 1002 and XPA 2001 The XPA 1002 and XPA 2001 audio amplifiers can be set on a table, mounted on a rack shelf, or mounted in the plenum space above a ceiling-mounted projector. Tabletop Use Four self-adhesive rubber feet are included with the audio amplifier. For tabletop use, attach one foot at each corner of the bottom side of the unit and place the unit in the desired location.
Rack mount ventilation recommendations Excessive heat can decrease the optimal lifetime of the power amplifier. An over temp indicator LED on the front panel of the amplifier lights red whenever the recommended operating temperature has been exceeded, (see “Front Panel Features and Operation” on page 4). XPA amplifier pairs can be mounted side-by-side in a single 1U rack.
Flexible Conduit Adapter Kit Installation WARNING: The circuit breaker used for this connection should be rated no lower than 20 amps and no greater than 30 amps. This unit must be installed in accordance with the National Electrical Code and with all local codes.
