Digital Controls
The digital controls, shown below are available when either DIGL, DIGU or DRM is selected. These
controls can also be found on the Setup Form- Audio Tab, VAC Sub-Tab (see next chapter, where you can
also find a more detailed description).
Figure 37: Mode Specific Controls - Digital
VAC: click to enable the virtual audio cables. If Auto Enable has been checked on the Setup Form-
Audio Tab, 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 supercedes 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 below, consist of two sections: Panadapter view and display mode
controls.
