• XPA 2001-100V mono audio power amplifier

Terms Used in this Manual

The terms “amplifier” and “power amplifier” are used interchangeably in this manual to refer
to all of the XPA models. “XPA 1002 series” refers to the XPA 1002, XPA 1002 Plus,
XPA 1002-70V, and XPA 1002-100V products. ”XPA2001” refers to both the XPA2001-70V
and the XPA2001-100V products.

Features

• Inputs — Balanced or unbalanced stereo or mono on a 3.5 mm, 5-pole captive screw

connector.

• Speaker outputs — Screw-lock, 5 mm captive screw connectors enable simple,

secure connections with 22 AWG to 12 AWG speaker cables.

• Continuous power output for larger rooms —

• XPA1002: 60watts rms per channel at 8 ohms; 100watts rms per channel at

4ohms.

• XPA 1002 Plus: 100 watts rms per channel at 4 and 8 ohms.

• XPA 1002-70V: 100 watts rms per channel for 70 volt speaker systems.

• XPA 1002-100V: 100 watts rms per channel for 100 volt speaker systems.

• XPA2001-70V: 200watts rms for 70volt speaker systems.

• XPA2001-100V: 200watts rms for 100volt speaker systems.

• Professional grade amplifier design —

• The XPA 1002 and XPA 1002 Plus features less than 0.05% total harmonic

distortion plus noise, and better than 105 dB signal-to-noise ratio.

• The XPA 1002-70V, XPA 1002-100V, and XPA 2001 series feature less than 0.1%

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 1

• 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 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 4

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.

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 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 (see the image below).

NOTES:

• On the XPA 2001 models, the single control adjusts the levels of both

channels simultaneously prior to summing them together.

• On some models (early XPA 1002, XPA 2001), this adjustment is referred to

as “level”. The function is the same, whichever way your product is labeled.

To adjust the attenuation 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
attenuation of the XPA fully counterclockwise.

2. Set the volume of the source device to its maximum volume level. No sound

should come out.

3. Return to the XPA amplifier and raise the attenuation 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.

E Balanced or unbalanced stereo or mono audio input receptacle

(XPA 1002 series) — Wire the 3.5 mm 5-pin captive screw connector for balanced

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.

Remote Volume Control (XPA 1002, XPA 1002 Plus, XPA 2001 Series)

Options for the 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, pin V (1) on the XPA is a 10 VDC reference voltage.
Pin C (2) is the volume control DC voltage input. The range is 0 to 10 V, where 0 V is mute
and 10 V provides maximum volume. Pin G (3) is ground.

NOTE: All nominal levels are at ±10%.

Controlling Multiple Amplifiers with One Volume Controller (XPA 1002, XPA
1002 Plus, XPA 2001 Series)

Multiple XPA 1002, XPA 1002 Plus, and XPA 2001 series 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 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 (XPA 1002, XPA 1002 Plus)

The power output of the XPA 1002 and XPA 1002 Plus can be effectively doubled by
bridging the output. Bridging allows power to be output in mono at 200 watts at 8 ohms.

• 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 potentiometers.

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.
