ATTENTION: Do not tie channel outputs 1 and 2 to each other or to ground.
Doing so will short the outputs, damage the amplifier, or both.
NOTE: The power output of the XPA 1002 series 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 beginning on page
19 ).
To wire the stereo audio output connector:
Step 1: Strip and insert the speaker wires into the connector and tighten the
captive screws. Be sure to observe the correct polarity.
Do not tin the wires!
Step 2: Insert the wired connector into the amplifier output and secure the locking
screws on either side.
