Extron electronics XTRA FULL RACK XPA 2002 User manual

XTRA™ Full Rack Series • Setup Guide
This guide provides basic instructions for an experienced installer
to set up and operate the Extron®XTRA Full Rack Series of
power amplifiers. All references refer to the
XTRA Full Rack Series: XPA 2002, XPA 2002-70V, 2003C-70V,
and 2004 User Guide.
• XPA 2002 outputs stereo audio at 200 watts rms per channel (4-ohm speakers) or
100 watts rms per channel (8-ohm speakers) on channels 1 and 2. Output is 400 watts
bridged mono (8-ohm speaker).
• XPA 2002-70V outputs 200 watts rms per channel on channels 1 and 2 for 70 V systems.
• XPA 2003C-70V outputs 200 watts per channel (4-ohm speakers) or 100 watts per channel
(8-ohm speakers) on channels 1 and 2, and 200 watts (70 V line, mono) on channel 3.
• XPA 2004 outputs stereo audio at 200 watts per channel (4-ohm speakers) or 100 watts
per channel (8-ohm speakers) on channels 1, 2, 3, and 4. Output is 400 watts per bridge
in bridged mono (8-ohm speakers) on bridge A (channels 1 and 2) and bridge B (channels
3 and 4).
Installation
NOTE: Adjust the audio level to =prior to the amplifier being powered back up in step 5.
See “Rear Panel Features and Operation” in the user guide.
1. Turn off all equipment including the XPA amplifier by toggling the power off and
disconnecting the power cords. Verify that the amplifier is disconnected from the
power source before proceeding.
2. Mount the amplifier — For diagrams of typical application examples, see “Application
Examples” in the user guide. For further mounting instructions, see “Mounting the XTRA
Series of Power Amplifiers” in the user guide.
3. Wire input to the 3.5 mm input connectors of the amplifier, as shown in the following
illustration. See “Rear Panel Features and Operation” in the user guide for bridging
information.

The wires must not be tinned: tinned wire does not
hold tight in the captive screws and can break easily
after several bends.
4. Wire the outputs — Wire speakers to the output connectors of the amplifier using the
included 2-pole (XPA 2002, XPA 2002-70V and XPA 2003C-70V) or 4-pole
(XPA 2003C-70V and XPA 2004) screw lock plug.

WARNING: Do not short the “+” and “_” outputs to each other. Doing so will short the
outputs and may damage the amplifier.
For complete wiring details, see “Rear Panel Features and Operation” in the user guide.
5. Bridge outputs (XPA 2002, XPA 2004) — Bridging the output of input 1 (for the XPA 2002)
or inputs 1 and 3 (for the XPA 2004) doubles the output of those inputs. See
“Bridged mode output” in the user guide for further details.
Bridge mode: XPA 2002
Bridging takes the signal from input 1 and outputs the
combined output of 400 watts from the + terminals of
output channels 1 and 2. Toggle the bridged output mode
switch up (bridged) or down (unbridged). See the diagram
at right.
Bridge mode: XPA 2004
Bridging takes the signal from input 1 or input 3 or both
and outputs the combined output of 400 watts from the
+ terminals of output channels 1 and 2 (Bridge A), or output
channels 3 and 4 (Bridge B), or both. Toggle the bridged
output mode switch up (bridged) or down (unbridged) for
the appropriate input channel. See the diagram at right.
NOTE: When bridging outputs, the minimum load impedance is 8 ohms.
6. Reconnect all power cords and switch on all other equipment before powering up the
power amplifier. The amplifier must be powered up last. The front panel LED of the amplifier
should light green.
7. Adjust the audio level using the rear panel
adjustment screws, shown at right.
8. Set the high pass filter — Use a small
screwdriver to toggle this switch between off
(no filtering) and 80 Hz. The XPA 2002-70V has two
switches, one for each output channel. The
XPA 2003C-70V has one switch for the 70V line
distribution output channel (channel 3). Setting the
switch to 80 Hz prevents the saturation of 70V speaker
input transformers by low frequency signals.
9. If desired, wire a contact closure device to the remote
standby connector. Connecting pin 2 to ground (pin 1)
places the amplifier in standby mode. Standby mode
turns off all outputs, although the amplifier is still receiving power.
Use the included 2-pin, 3.5 mm captive screw connector to jumper the pins.
