DAttenuation (channels 1 and 2) — Use a small screwdriver to adjust the audio input
level for the corresponding channel. The analog potentiometers control the level from
= (full attenuation) to 0 dB.
NOTES: • On the XPA 2001, the single control adjusts the levels of both channels simultaneously prior to summing them together.
•On some models, this adjustment is referred to as “level”. The function is the same, whichever way your product is labeled.
To adjust the input level of the XPA amplifier, 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 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 amplifier and raise the level until sound distortion occurs, then lower the level slightly until any distortion disappears. This setting ensures that, whatever the source device volume setting may be, no clipping occurs.
NOTE: When setting volume control through a source device, ensure that the volume of the device is set to variable out. Consult the user manual of the device for detailed instructions on its calibration.

NOTE: The output power of the XPA 1002 can be effectively doubled by using only one input channel and bridging the output. The XPA 1002 will output
200 watts @ 8 ohms in bridged mode. See “Bridged Mono Output” on page 19 for wiring instructions when bridging the XPA 1002.
