Features
Extron Patented Class D Ripple Steering (CDRS™) technology — CDRS is an Extron
patented technology that provides a smooth, clean audio waveform and an improvement
in signal fidelity over conventional Class D amplifier designs. CDRS eliminates the high
frequency switching ripple characteristic of Class D amplifiers, a source of RF emissions,
which can interfere with sensitive A/V equipment such as wireless microphones.
Professional grade signal-to-noise and THD performance — Delivers professional
grade performance with 100 dB signal-to-noise ratio and THD of less than 0.1%.
Front and rear panel LED indicators —
zz Display limiter/protect status when audio clipping or amplifier malfunction occurs.
zz Indicate the presence of input signals.
Audio level adjustment — Potentiometers to adjust the audio level from = (full
attenuation) to 0 dB (no attenuation).
IEC power switch — Rear panel IEC rocker power switch.
1U full rack enclosure — The capability to deliver full-sized amplifier power in one half
the size of many comparable power amplifiers.
High pass filtering — A high pass filter (XPA 2002-70V, XPA 2002-100V,
XPA 2003C-70V, and XPA 2003C-100V only) toggle switch prevents saturation of speaker
input transformers by low frequency signals. Saturation can result in severe distortion of
the speaker output signal.
Bridged output mode — The XPA 2004 has a toggle switch to input channels 1 and 3
and output each input as a single bridged output channel at twice the power of a single
channel. Input 1 is output over the positive terminals of output channels 1 and 2. Input 3
is output over the positive terminals of output channels 3 and 4.
The XPA 2002 has a toggle switch to input channel 1 and output a single bridged output
channel at twice the power using the positive terminals of channels 1 and 2.
Convection cooled, fanless operation — Ensuring quiet reliable operation. All models
generate substantially less heat than similar power amplifer designs.
Automatic clip limiter — Detects actual onset of clipping by comparing input and output
waveforms. Gain is automatically reduced with a slow attack and fast release to eliminate
clipping. This advanced limiter design protects the speakers from clipping distortion and
offers superior sonic characteristics compared to limiters that use signal compression.
Rear panel recessed, detented level controls — Provide attenuation of input signals
for adjusting audio system gain staging as well as multi-zone applications. They are
located on the rear panel to prevent users from tampering with level adjustments.
Remote standby — Standby control that remotely shuts off all amplifier output while
power remains active at the amplifier.
Power factor correction — Features power factor correction technology that smoothes
out the high peak currents of the current draw of the amplifier, thus minimizing the
presence of high frequency harmonics on the AC power line, and therefore preventing
audible artifacts from being transmitted to other audio equipment in the system.
Class 2 wiring — The outputs from the amplifiers support Class 2 wiring that meets UL
requirements.
ENERGY STAR® qualified — All models are ENERGY STAR qualified amplifiers that
conserve energy and reduce costs.

a Power indicator LED — This LED lights:
zz Green when the amplifier is receiving full power.
zz 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 d
b Over Temp indicator LED — This LED lights red when the amplifier exceeds the
recommended operating temperature for optimal lifetime. The LED turns 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.
•
•
Avoid placing other equipment on top of the amplifier.
Verify that the operating temperature is within the specified range.
c Signal indicator LEDs (channels 1, 2, 3, and 4) — These LEDs (representing input
channels 1, 2, 3, and 4) light green only when an input signal is detected on the
corresponding channel.
NOTE: These LEDs are also located on the rear panel.
d Limiter/Protect indicator LEDs (channels 1, 2, 3, and 4) — These LEDs
(representing output channels 1, 2, 3, and 4) light red under the following
circumstances:
•
•
•
When audio clipping occurs, the corresponding channel’s LED 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.
When DC output is detected, the amplifier is malfunctioning and the LED for the
corresponding channel is lit. The amplifier requires servicing when this event
occurs.
•
When the output leads are shorted, the LED of the corresponding channel is lit
until the short is removed.
NOTE: These LEDs are also located on the rear panel.

a AC power connector — Connect a standard IEC AC power cord here for power
input (100 VAC to 240 VAC, 50/60 Hz) to the internal, autoswitching power supply.
b Power switch — This rocker switch turns power to the amplifier on or off. The off
position also disables remote standby (see d).
c Power indicator 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.
d Remote standby connector — Connecting pin 2 to ground (pin 1) places the
amplifier in standby mode. Standby mode turns off all outputs, although the amplifier
is still receiving power.
NOTE: The amplifier automatically enters standby mode after 25 minutes of
inactivity (+/- 5 minutes).
Use the included 2-pin, 3.5 mm captive screw connector to jumper the pins.

e Limiter/Protect indicator LEDs (channels 1, 2, 3, and 4) — These LEDs
(representing output channels 1, 2, 3, and 4) light red under four circumstances:
•
•
•
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 cools down and recovers from the overheated condition.
When DC output is detected, the amplifier is malfunctioning and the LED for
the corresponding channel is lit. When a malfunction occurs, power down the
amplifier and power it back up. If the LED still remains lit, the amplifier requires
servicing.
•
When the output leads are shorted, the LED of the corresponding channel is lit
until the short is removed.
f Signal indicator LEDs (channels 1, 2, 3 and 4) — These LEDs (representing input
channels 1, 2, 3 and 4) light green only when an input signal is detected on the
corresponding channel.

i High pass filter toggle switch — Use a small screwdriver to toggle this recessed
two-position toggle switch that alternates between Off (no filtering) and 80 Hz. The
XPA 2002-70V and XPA 2002-100V have 2 switches, one for each output channel.
The XPA 2003C-70V and XPA 2003C-100V have one switch for the line distribution
output channel (channel 3). Setting the switch to 80 Hz prevents the saturation of
the speaker input transformers by low frequency signals. Saturation may result in
undesired overheating of the speaker transformers.

Mounting
The XPA power amplifiers can be set on a table; mounted on a rack shelf; mounted under
a desk or other furniture; 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 Rack Mounting Guidelines
The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of
the equipment in a rack.
1. Elevated operating ambient temperature — If installed in a closed or multi-unit
rack assembly, the operating ambient temperature of the rack environment may
be greater than room ambient temperature. Therefore, install the equipment in an
environment compatible with the maximum ambient temperature (Tma =
+122 °F/+50 °C) specified by Extron.
2. Reduced air flow — Install the equipment in a rack so that the amount of air flow
required for safe operation of the equipment is not compromised.
3. Mechanical loading — Mount the equipment in the rack so that a hazardous
condition is not achieved due to uneven mechanical loading.
4. Circuit overloading — Connect the equipment to the supply circuit and consider
the effect that circuit overloading 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) — Maintain reliable grounding of rack-mounted
equipment. Pay particular attention to supply connections other than direct
connections to the branch circuit (for example, use of power strips).
Rack Mounting
The XTRA series of audio amplifiers are housed in rack-mountable metal enclosures with
pre-attached mounting ears for standard 19-inch racks. Mount the amplifier, as follows:
1. Disconnect all cables and power sources from the amplifier.
2. Position the amplifier in the mounting rack so that the four slots in the mounting ears
are aligned with the rack mounting holes. Use the included mounting screws to fasten
the amplifier to the rack, as shown in the following diagram.
WARNING: Never place a load exceeding 40 pounds in weight on top of the
rack-mounted amplifier.

Rack Mounting Ventilation
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
To reduce the chances for an over temp condition, the XPA should be arranged in a rack
environment with up to a maximum of four XPAs stacked together with a minimum of
one vent space provided both above and below a stack, as shown below.
