The Properties page for the Speakers device appears as follows:

The output levels can be set under the Levels tab, with a master output 
fader and individual faders for wave output and input monitoring. Each 
fader has a Balance button which allows the eight individual channels to be 
adjusted.

The default master input and output levels correspond to a gain setting of 
0dB. When set to full scale, a 6dB boost is applied.

Output Mapping

The playback speaker mapping can be tested by opening the Windows 
playback devices, selecting the Digitorc 4 speakers device and clicking on 
the 

Configure

 button.
