ENERGY STAR
®
qualified amplifier — The XTRA Series of amplifiers are energy
efficient products that conserve energy and reduce operating costs.
Highly efcient Class D amplier 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 Ampliers • Introduction 1
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.
Screw lock, 5 mm captive screw speaker connectors — Enable simple, secure
connections with 22 to 14 AWG speaker cables.
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.

channels are marked 1 and 2. Wire the included 4-pole, 5 mm screw lock captive screw connector to output stereo audio. Observe the correct polarities for each channel (see the steps on the following pages). The output is designed to power 4 or 8 ohm speakers and is rated at 50 watts per channel.
NOTE: You must use Class 2 wiring for this output to comply with UL requirements.
WARNING: Do not tie channel outputs 1 and 2 to each other or to ground. Doing
so will short the outputs and damage the amplifier.
NOTE: 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 at 8 ohms or 120 watts at 16 ohms in bridged mode.

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 Ampliers • References 17
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.

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. An ALL-POLE MAINS SWITCH with a contact separation of at least 3 mm in each pole shall be incorporated in the electrical installation of the building. The installation shall be carried out in accordance with all applicable installation rules.
Installation and service must be performed by a qualified electrician only.
CAUTION: A UL listed electrical distribution box is recommended for the termination of the
conduit opposite the XPA (see the “UL requirements” section below).
The optional Flexible Conduit Adapter Kit (part number 70-228-02) consists of:
One EMT adapter plate
One 6-foot long electrical conduit
Three 7.5 feet, 18-gauge spade connector power wires
One UL rated zip tie wrap
Three auxiliary crimp style spade connectors designed for 14- to 16-gauge wires
NOTE: If needed, Extron recommends using a UL-rated crimp tool to terminate the
spade connectors. One recommended choice is the Molex crimp tool (Molex 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.
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.
