Extron electronic XPA 1002 User Manual

XPA 1002 Audio Power Amplifier

The Extron XPA 1002 is a half-rack width, two-channel, stereo audio power amplifier that outputs 60 watts per channel (8-ohm speakers) or 100 watts per
channel (4-ohm speakers). The XPA 1002 utilizes Extron’s patented CDRS™ Class D Ripple Suppression technology to reduce EMI. The audio level
adjustment feature prevents the occurrence of audio clipping.

OVER
TEMP

This front panel LED lights red when the amplifier
exceeds the recommended ambient temperature for
optimal lifetime. The LED turns off after the amplifier
cools down sufficiently. See the User’s Manual.

PROTECT

These front and rear panel LEDs (representing output channels 1
and 2) light red under three circumstances:

• When audio clipping occurs, the corresponding channel’s

LED blinks once per clip occurrence.

• When the amplifier overheats, both LEDs are lit. The LEDs

are not lit after the amplifier cools down and recovers from
the overheated condition.

• When DC output is detected, the amplifier is malfunctioning

and the LED for the corresponding channel is lit. Power down the
amplifier and power it back up. If the LED still remains lit after a
power cycle, the amplifier requires servicing.

SIGNAL

These front and rear panel LEDs
(representing input channels 1 and 2)
light green only when an input signal is
detected on the corresponding channel.

Level adjustment

LEVEL

0 0

To adjust the XPA amplifier's input level, do the following:

1. Make sure that the source signal is active.

2. Before powering up the amplifier, adjust the output level(s) to

the lowest setting (fully counterclockwise).

3. Power up the amplifier.

4. Adjust level(s) by turning the adjustment clockwise until audio

distortion begins to occur, then back off the adjustment
(turning counterclockwise) until the distortion disappears.

Level adjustment (channels 1 and 2) —
Use a Tweeker or small screwdriver to
adjust the audio input level for the
corresponding channel. The analog
potentiometers control the level from -=
(full attenuation) to 0 dB.

Automatic standby mode

The XPA goes into standby mode after approximately one hour of
inactivity. The XPA comes out of standby mode approximately one
second after detecting an input signal (unless in manual standby —
see “Remote control connector”).

N You must use Class 2 wiring for this output to comply with
UL requirements.

W Do not tie channel outputs 1 and 2 to each other or to
ground. Doing so will short out the outputs and/or damage
the amplifier.

Audio output wiring

Stereo audio output connector (channels 1
and 2) — Marked "1" and "2" for the output

channels, wire the included 4-pole, 5.08 mm
screw lock captive screw connector to output
stereo audio through either channel. Observe

Remote control connector

Remote control connector — The 3.5 mm 5-pin

captive screw receptacle is used to remotely
control two functions through contact closure:

1. As shown on the left, pins 1, 2, and 3 control
volume by varying the DC voltage from 0 V (full
attenuation) to 10 V (maximum volume) with full
muting in effect when pin 2 is connected to
ground (pin 3). See the circuit diagram below.
