Remote control connector — The 3.5 mm 5-pole captive screw receptacle is used
to remotely control two functions through contact closure (see the following circuit
diagram).
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). Use the included 3-pole captive screw connector (see “Remote
Volume Control” on page 11 ).

Connecting pin 5 to ground (pin 4) places the amplifier in standby mode as long
as pin 5 is grounded. Standby mode turns off all output, although the amplifier is
still receiving power. Use the included 3.5 mm 2-pole captive screw connector to
remotely ground pin 5.
The power indicator LED lights amber when the amplifier is in standby mode.

Stereo audio output connector (channels 1 and 2) — The output
channels are marked 1 and 2. Wire the included 4-pole, 5 mm screw
lock captive screw connector to output stereo audio. Observe the
correct polarities for each channel (see the steps on the following
pages). The output is designed to power 4 or 8 ohm speakers and is
rated at 50 watts per channel.
NOTE: You must use Class 2 wiring for this output to comply with UL requirements.
WARNING: Do not tie channel outputs 1 and 2 to each other or to ground. Doing
so will short the outputs and damage the amplifier.
NOTE: XPA 1002 output power can be effectively doubled by using only one input
channel and bridging the output. The XPA 1002 will output 200 watts at
8 ohms or 120 watts at 16 ohms in bridged mode.
See “Bridged Mono Output” on page 12 for wiring instructions.
