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.

XTRA Series Half-Rack Audio Power Amplifiers • Installation 5
Mounting the XTRA Series Amplifiers
The XPA 1002 series and XPA 2001 series of 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.
UL Guidelines for Rack Mounting
The following Underwriters Laboratories (UL) guidelines pertain to the installation of the
equipment in a rack.
1. Elevated operating ambient — If installed in a closed or multi-unit rack assembly,
the operating ambient temperature of the rack environment may be greater than room
ambient. Therefore, consider installing the equipment in an environment compatible with
the maximum ambient temperature specified by the manufacturer [Tma = +32 to +122
°F (0 to +50 °C)].
2. Reduced air flow — Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation of the equipment is not compromised.
3. Mechanical loading — Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
4. Circuit overloading — Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits might have
on overcurrent protection and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this concern.
5. Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment
should be maintained. Particular attention should be given to supply connections other
than direct connections to the branch circuit (such as the use of power strips).
Rack Mounting
The XPA 1002 series and XPA 2001 series can be mounted in a rack shelf using the optional
RSU 129 1U Universal rack shelf or the 1U Basic rack shelf, as follows.
1. If feet were installed on the bottom of the amplifier, remove them.
2. Place the amplifier on one half of the rack shelf.
3. Align the front of the amplifier with the front of the shelf, and align the threaded
holes on the bottom of the amplifier with the holes in the rack shelf.
4. Attach the amplifier to the rack shelf with the two provided 4-40 x 3/16” machine
screws.
ATTENTION:
• Using screws longer than 3/16" will damage the unit and void the warranty.
• L’utilisation de vis plus longues que 3/16" endommagera l’unité et annulera la
garantie.
5. Insert the screws from the underside of the shelf, and securely fasten them into
diagonally-opposite corners.

6. Attach the false front panel (provided with rack shelf) to the unoccupied side of the rack
(as shown on the previous page), or install a second half-rack-width device in that side
by repeating steps 1 through 5.
7. Attach the rack shelf to the rack using four 10-32 x ¾” bolts (provided). Insert the bolts
through #10 beveled washers, then through the holes in the rack, as shown above.
Rack mounting 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10).
To reduce the chances for an over temp condition, the XPAs should be arranged in a rack
environment so that adequate airflow is available both above and below the XPA whenever
possible. No more than two XPAs should be stacked in a rack without an open space
between them, as shown in the following illustration. An XPA can also be arranged above
or below another non-XPA device, but there must be an open space both above and below
those devices (see figure5).

NOTE: The UL-approved electrical distribution box is not included with either the
XPA or the Flexible Conduit Adapter Kit. The installer is responsible for obtaining
and installing the box.
Installing the Flexible Conduit Kit
ATTENTION:
• Electrostatic discharge (ESD) can damage IC chips even though you cannot feel
it. You must be electrically grounded before touching anything inside the XPA. A
grounding wrist strap is recommended.
• Les décharges électrostatiques peuvent endommager les puces de circuit
même si vous ne pouvez pas les sentir, les voir ou les entendre. Vous devez être
électriquement relié à la terre avant de toucher quoique ce soit à l’intérieur du XPA.
Un bracelet de mise à la terre est recommandé.
Install flexible conduit to the XPA by following the steps below.
1. Unplug the IEC power cord from the power amplifier.
2. Remove the 8 screws from the top and sides of the XPA and lift off the cover
(see figure6).

APower LED — This LED lights:
• Green when the amplifier is receiving full power.
• Amber when the amplifier is in Standby mode. Standby mode turns off all outputs
from the amplifier, although the amplifier is still receiving power (see Rear Panel
Features and Operation on page12 and Gand Hon page15).
BOVER TEMP LED — This LED lights red when the amplifier exceeds the
recommended operating temperature for optimal lifetime. The LED will turn off after the
amplifier has cooled down sufficiently.
Should the LED light, check the following:
• Verify that the placement of the amplifier allows for adequate ventilation and airflow
(see figure5 on page6).
• Avoid placing other equipment on top of the amplifier.
• Verify that the operating temperature is within the specified range.

(representing their respective output channels) light
red under three circumstances:
• When the output wiring is shorted together.
• When audio clipping occurs, the LED of the corresponding channel blinks once per
clip occurrence.
• When the amplifier overheats, both LEDs are lit. The LEDs are not lit after the
amplifier recovers from the overheated condition.
NOTE: These LEDs are also located on the rear panel.
DSIGNAL LEDs — These LEDs (representing their
