• XPA 1002 Plus two-channel stereo audio power amplifier

• XPA 2001-70V mono audio power amplifier

• 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” refers to the 1002 and the 1002 Plus. ”XPA2001”
refers to both the XPA2001-70V and the XPA2001-100V.

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.

Extron patented CDRS — Class D ripple suppression — A patented, exclusive

XTRA Series Half-Rack Audio Power Amplifiers • Introduction

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 — Allows the XPA 1002 series 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 wiring instructions on page 19).

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.

Rack Mounting Ventilation Recommendations

XTRA Series Half-Rack Audio Power Amplifiers • Installation

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 models, 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 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 be heard.

3. Return to the XPA amplifier and raise the attenuation until sound distortion

occurs, then lower the level slightly to remove any distortion. This setting ensures
that, whatever the source device volume setting is, 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

XTRA Series Half-Rack Audio Power Amplifiers • Operation

Several XPA 1002 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. If complete muting is
required, use a contact closure switch attached between the C (Vol/Mute) and
the G (ground) pins 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.

ATTENTION: Failure to follow these instructions may result in damage to the unit.
Electrostatic discharge (ESD) can damage IC chips even though you cannot feel it. You must be electrically grounded before touching anything inside the XPA. A grounding wrist strap is recommended.

XTRA Series Half-Rack Audio Power Amplifiers • Operation

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.

NOTES:

• The bridging instructions that follow apply only to the XPA 1002 series.

• 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.
