Managing Audio Levels
The Videobar VB1 has four audio inputs: its microphones, USB audio,
Bluetooth audio, and the analog input (Audio In jack).
The VB1 also has three audio outputs: its speakers, USB audio, and
Bluetooth audio.
The real-time levels of all of these signals except for the Audio In jack can
be seen in the Meters tab of the Videobar Configuration app/WebUI.
Local Audio Playback
Music or audio over the USB, Bluetooth , or analog inputs are played back
through the VB1 speakers. This audio is not sent to the far end during
meetings.
Meeting Audio
The VB1 microphone audio is sent to the far end (via the USB output) after
the Acoustic Echo Cancellation (AEC) feature.
If local audio playback is sent over the USB input, it will play over the
VB1 speakers, but the AEC feature will remove the music from the VB1
microphone audio pick-up before sending it to the far end.
If you wish to send local audio playback to the far end, share the audio
playback app within your meeting software.
Adjusting Audio Levels
The VB1 has two volume controls: for the VB1 speakers and for the analog
input (Audio In) gain.
To adjust the volume of the VB1 speakers, use the Volume + or − buttons
on the remote control, adjust the volume of the host computer, or adjust
the volume of the Bluetooth audio. These three volume levels are always
synchronized, so adjusting one of them adjusts the others as well.
Note: All remote-control functions are also available in the software apps
that enable you to configure the Videobar VB1. See Software Applications
(Page 23) for more information.
If needed, adjust the Analog Input Gain to trim the signal sent into the
Audio In jack so it matches the nominal levels from the host computer
and Bluetooth audio. You can do this in the Videobar Configuration app or
WebUI or in the Videobar Administration app (see Software Applications
(Page 23)).
