Volumn Control
Click on the Volumn Control tab and the following screen appears.
You may regulate each volumn to the speaker for current playing digital sound
sources. If you use 2-channel speaker, only Front Left and Front Right bars are
available for you to configure. If you use 4-channel speaker, only Front Left,
Front Right, Rear Left and Rear Right bars are available. In 6-channel mode,
you may adjust all the speakers as showed above.
Loudness (AGC): Loudness w/Auto-Gain-Control: When you want a
higher volume level of digital audio, you can enable Loudness (AGC). It
provides extra +3dB to +12dB gain to all channels. The driver has also
been designed with a sophisticated auto gain
control minimizing the signal clipping distortion.
However, it is not recommended to enhance the
volume too much here if you want a best sound
quality. The best way is to increase the volume
of external speakers or just to increase the Master
Volume in Microsoft Volume Control.
Using 2-, 4- or 6-Channel Audio Function
Left-click Microsoft "Volume Control"
icon once and you'll get the Master
Volume control slider.
