On the XPA 2001, the single control adjusts the levels
of both channels simultaneously prior to summing them
together.
To adjust the XPA amplier's input level, do the following:
1. If connecting to a source device with a volume control
(variable output), ensure that the volume on the source
device is set to its lowest point, then adjust the level(s) of
the XPA fully counterclockwise.
2. Set the source device's volume to its maximum volume
level. No sound should come out.
3. Return to the XPA amplier and raise the level(s) until
sound distortion occurs, then lower the level(s) slightly
until any distortion disappears. This setting ensures that,
whatever the source device volume setting may be, no
clipping occurs.
N
When setting volume control through a source device,
ensure that the device's volume is set to variable out.
Consult the device's user manual for detailed instructions
on its calibration.

The XPA 1002's output power can be effectively doubled
by using only one input channel and bridging the output.
The XPA 1002 will output 200 watts @ 8 ohms or 120
watts @ 16 ohms in bridged mode.
See "Bridged mono output" in this chapter for wiring
instructions when bridging the XPA 1002.
