Figure 2. XPA 2001 Series Application Example
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 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.
XTRA Series • Installation

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 or XPA 2001 can be mounted in a rack shelf using the optional
RSU 129 1U Universal rack shelf (Extron part #60-190-01) or the 1U Basic rack shelf
(Extron part #60-604-02), 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.
• 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.
3. • Attach the amplifier to the rack shelf with the two provided 4-40 x 3/16” machine
screws.
• Insert the screws from the underside of the shelf, and securely fasten them into
diagonally-opposite corners.
See the following illustration.

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 9.
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 arranged one-on-top-of-the-other
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.

NOTES: • On the XPA 2001, the single control adjusts the levels of both channels
simultaneously prior to summing them together.
• On some models, this adjustment is referred to as “level”. The function
is the same, whichever way your product is labeled.
To adjust the input level of the XPA amplifier, do the following:
1. If connecting to a source device with a volume control (variable output), ensure
that the volume on the source device is set to its lowest point, then adjust the
level of the XPA fully counterclockwise.
2. Set the source device’s volume to its maximum volume level. No sound should
come out.
3. Return to the XPA amplifier and raise the level until sound distortion occurs, then
lower the level slightly until any distortion disappears. This setting ensures that,
whatever the source device volume setting may be, no clipping occurs.
NOTE: When setting volume control through a source device, ensure that the
volume of the device is set to variable out. Consult the user manual of
the device for detailed instructions on its calibration.

Controlling Multiple Amplifiers with One Volume Controller
Several XPA 1002 and XPA 2001 units can be daisy-chained so that one volume controller
can simultaneously regulate the volume of all the amplifiers.
NOTES: • As additional amplifiers are added to the daisy chain, the sensitivity of
the volume potentiometer will change. The maximum volume level (fully
clockwise) will not be affected. However, the effectiveness of the minimum
volume level (fully counterclockwise) in reducing the volume to inaudible
levels decreases as more amplifiers are added to the daisy chain.
• When more than two XPA Half-Rack units are attached to the chain, sound
may be heard even if the levels have been set to their lowest. The muting
of the output, however, can be remedied with a contact closure button
attached between the Vol/Mute and the Ground pin of the first
XPA Half-Rack unit in the chain.
To regulate multiple amplifiers with a single volume controller:
1. Attach all three pins of the volume controller to the corresponding pins on the first
XPA Half-Rack unit only — Ground to G (ground), Vol/Mute to C (Vol/Mute),
and 10 V to V (10 V).
2. Use jumper wires to connect the C (Vol/Mute) pins of the first amplifier and each
successive amplifier.
3. Use jumper wires to connect the G (ground) pins of the first amplifier and each
successive amplifier.

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 at 8 ohms.
NOTES: • The bridging instructions that follow apply only to the XPA 1002 model.
• The minimum load impedance when bridging is 8 ohms.
To bridge the output, follow the steps and refer to the diagram below:
1. Unplug the IEC power cord from the power amplifier.
2. Fully attenuate the potentiometer.
3. Wire the output as shown in the following diagram.
4. Wire the input as shown in the following diagram.
5. Connect the IEC power cord and power up the amplifier.
6. Adjust the input levels of channels 1 and 2 identically.
