Extron XPA 1002 - 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.

C

Connect the sleeve to

ground (Gnd). Connecting

the sleeve to a negative (-)

terminal will damage the

audio output circuits.

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.

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.

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.

Audio output wiring

Remote control connector

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

the correct polarities for each channel. Speaker output is rated at 100
watts per channel (4-ohm speakers) or 60 watts per channel (8-ohm
speakers).

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.

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.

N

Maximum volume

output is dependent
on input level
adjustment.

2.

As shown below, pin 5

connected to ground
(pin 4) places the amplifier
in standby mode. Standby mode turns off all output(s),
although the amplifier is still receiving power. Use the
included 2-pin, 3.5 mm captive screw connector plug to remotely
ground pin 5.

This front panel LED lights red when the amplifier

Remote Switching to 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”).
