Configuring Microphone and Speaker Volume
The volume of attached microphones and of the internal speaker can be digitally increased or decreased by the
Video Gateway. Microphone volume can be modified to optimize the sound level of audio that is played by client
software. Internal speaker volume can be adjusted to suit the location of the Video Gateway unit and the needs of
those on-site.
You can choose from 11 levels of amplification. Level 5 means the volume is not modified at all. Levels 0 through
4 cause the volume to be reduced (the smaller the number, the greater the reduction); levels 6 through 10 cause it to
be amplified (the greater the number, the greater the amplification). Level 6 is generally optimal for the internal
speaker, level 9 for passive microphones, and level 5 for active microphones.
You can test the volume settings as you configure them by connecting to the Video Gateway using a client
application. Volume levels can be adjusted for testing purposes without resetting the Video Gateway unit.
Configuring Internal-Speaker Volume
You can optimize the internal-speaker volume settings by testing them as you configure them.
To configure the volume of the internal speaker:
1. Make sure someone is near the Video Gateway to listen to sound being transmitted from the speaker.
2. Using a client application that can transmit audio to a Video Gateway (SVMultiClient and some of the cellular
client applications), connect to the Video Gateway.
3. Speak into the microphone of the client device and check with the listener to find out if the volume is
appropriate. If it is not, adjust the settings as described below until they are satisfactory.
4. In the
Audio Settings
screen, under
Internal Speaker Volume
, select a volume setting.
