XPA U 1004 SB and XPA U 2002 SB • Operation

2.
Set the source device volume to the maximum level. No sound should come out.
3.
Raise the attenuation on the XPA Ultra Series amplifier until sound distortion occurs,
then lower the attenuation level slowly until distortion disappears. This setting
ensures no clipping occurs, whatever the source device volume setting is.
NOTE:
When setting volume control through a source device, make sure the
device’s volume is set to variable out. Consult the device’s user manual for
detailed instructions on its calibration.
When volume is controlled at the amplifier:
1.
If volume will be controlled at the amplifier using a remote volume control
(see section G for details), ensure the volume on the source device is set to its
lowest point, then adjust the attenuation of the amplifier fully counterclockwise.
2.
Set the source device’s volume to its maximum level.
3.
Set the remote volume control to its maximum level. No sound should come out.
4.
Raise the attenuation on the XPA Ultra Series amplifier until sound distortion occurs,
then lower the attenuation level slowly until distortion disappears. This setting
ensures no clipping occurs, whatever the source device volume setting is.
NOTE:
When volume will be controlled at the amplifier using a remote volume
control, make sure the source device’s audio output is set to fixed out (local
volume control is disabled). Consult the device’s user manual for detailed
instructions on its calibration.
