ENERGY STAR
®
qualified amplifier — The XTRA Series of amplifiers are energy
efficient products that conserve energy and reduce operating costs.
Highly efcient Class D amplier 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 A/V devices without RF interference.
Convection cooled — The XTRA Series of amplifiers are convection cooled without the
need for fans, ensuring quiet, reliable operation.
XTRA Series Power Ampliers • Introduction1
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, part number 70-228-02.
Auto power-down with fast power-up — The amplifiers automatically enter
standby mode (power-down) after one hour of inactivity, dramatically reducing power
consumption. They quickly return to full power status upon signal detection.
Rear panel 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 — Activate during excessive clipping, 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 amplifiers to be
remotely controlled using the optional Extron VCM 100 Series volume and mute or
VC 50 volume controllers, and the MLA VC10 series volume control modules.
Bridgeable outputs — The power output of the XPA 1002 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 output at 200 watts
into 8 ohms or 120 watts into 16 ohms. The minimum load impedance when bridging
is 8 ohms.
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.

Level adjustment (channels 1 and 2) — Use a small flat blade screwdriver to adjust
d
the audio input level for the corresponding channel. The analog potentiometers control
the level from -= (full attenuation) to 0 dB (no attenuation).
NOTE: On the XPA 2001, a single control simultaneously adjusts the levels of both
channels prior to summing them together.
XPA Input Level Adjustment:
1. If connecting to a source device with a volume control (variable output), ensure the
volume on the source device is set to its lowest point, then adjust the levels of the
XPA amplifier fully counterclockwise (–=).
2. Now set the source volume to its maximum volume level. No sound should be
heard.
3. Return to the XPA amplifier and raise the levels until sound distortion occurs, then
lower the levels slightly until any distortion disappears. This setting ensures that,
regardless of the source device volume setting, no clipping occurs.
NOTE: When setting volume control through a source device, ensure the
volume of the device is set to variable out. Consult the user manual
for the device for detailed instructions on its calibration.

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.
NOTE: Filtering may be unnecessary if filtering is applied to the source input signal
upstream of the amplifier.
Remote Volume Control
Options for remote control of the XPA amplifiers include the Extron VCM 100 and VC 50
volume controllers. Third party 10k potentiometer volume controllers can also be connected
to this port.
As shown in the following illustration, the remote connector pin 1 is a 10 VDC reference
voltage. Pin 2 is volume control DC voltage, range is 0 to 10 V, where 0 V is mute and 10 V
provides maximum volume. Pin 3 is ground.

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.
NOTE: The + terminal of Output channel 1 becomes the positive output terminal and
the + terminal of Output channel 2 becomes the negative output terminal.
3. Wire the input (balanced
, or unbalanced Ö ) 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.
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 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 (e.g. use of power strips).
Rack Mounting
The XPA 1002 or XPA 2001 can be mounted in a rack shelf using the optional RSU 129 1U
Universal rack shelf (Extron part number 60-190-01) or the 1U Basic rack shelf (Extron part
number 60-604-01). Follow the instructions included with the rack shelf kits.
XTRA Series Power Ampliers • References17
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. When XPA amplifiers
are mounted above or below other non-XPA devices that may generate significant heat,
allow for open space as needed between the XPA and non-XPA devices.
XPA amplifiers can also be arranged one pair-on-top-of-the-other and stacked in a rack
without an open space between them. Up to four pairs of amplifiers may be stacked in a
typical installation before requiring a vent space between other sets as illustrated below.
NOTE: Additional units or pairs may be added to a stack of four pairs depending on the
frequency and typical power output levels of the amplifiers during operation.
Monitor the OverTemp LED to verify whether additional stacked units will work
for a given installation.

part number 19285-0008).
The kit provides a convenient means to replace the IEC power cord with conduit, where
required by local codes.
CAUTION: Make sure that the source device and the XPA are turned off and
disconnected from the power source before you begin.
UL requirements
The Underwriters Laboratories (UL) requirements listed below pertain to the installation of
the flexible conduit onto a XPA 1002 or XPA 2001.
This unit is not to be used beyond its rated voltage range.
This unit must be wired to a UL listed distribution box.
