Digital Controls
The digital controls, shown below are available when either DIGL, DIGU or DRM is selected. These
controls can mostly be found on the Setup Form- Audio Tab, VAC Sub-Tab (see page 73, where you can
also find a more detailed description).

VAC:

Virtual Audio Cable
(
http://software.muzychenko.net/eng/
), a third party
program (written by Eugene Muzychenko) to enable digital audio transfer between PowerSDR
and other third party (digital) programs. See also the Setup Form – Audio Tab, VAC Sub-Tab
described on page 73. If
Auto Enable
(page 74) has been checked on VAC Sub-Tab, then VAC
will automatically be enabled when either DIGL, DIGU or DRM is selected.
RX & TX Gain:
Adjust the gain for signals coming in and out of the VAC interface. Use the RX
Gain control to adjust the audio level going to third party programs. (Note that for third party
applications this control supersedes the front panel AF control). Similarly, use the TX control to
adjust the volume of audio coming from third party applications (adjust for 0 dB on the ALC
meter).
Sample Rate:
sets the sample rate of the VAC interface. This needs to be matched to your
third party software sample rate.
Mono/Stereo:
sets the VAC interface to operate either mono or stereo. This can be of
importance, depending on your third party software. (E.g. MixW requires the mono setting,
whereas DREAM requires stereo).
(9) Display Controls
The main display controls, shown in Figure 44 below, consist of two sections: Screen adjustment
controls and
display selection controls. The former act on the screen as a whole, where as the latter
determine the display type to be used.
