LEVEL CONTROLS
The UAX220 provides level adjustment and mute controls on the outputs of
the D/A converters. These controls are applied to both line and headphone
outputs. By default, the output level of the D/A converter is set to maximum: a
full scale digital signal of 0 dBfs is thus restored at +10 dBu. This operating
mode is recommended to obtain finest audio quality.On the inputs, there are
no controls available.
You will rarely access these controls, as the headphone level potentiometer
gives you direct access to its volume control.
However, in case you’d like to modify the D/A converter output, this is how to
proceed under Windows XP and Mac OS X:
