Your RAV system is pre-configured for optimal audio quality right out of the box. However,
you can customize the audio and adjust the volume to match user preferences. You can also
change the mix of audio being sent to the far-end conference site and recording devices.
Microphones
You can adjust microphone volume and enable or disable ALC (automatic level control) in
the Microphone Settings window. Automatic Level Control automatically adjusts microphone
levels to ensure participants’ voices are transmitted at consistent levels regardless of whether
people are speaking loudly or softly.
To access Microphone Settings
• Click the Mic Pod icon on the Configuration screen.
To enable ALC
• Click the ALC button. The indicator will turn green when
ALC is enabled and the audio level sliders will be
disabled.
To adjust audio level (volume)
• Using the slider, adjust the volume. The meter will display
output levels.
To disable Acoustic Echo Cancellation (AEC)
1. Click the Advanced button.
2. Click AEC to disable Acoustic Echo Cancellation.
Note: AEC prevents echo from reaching the far-end site.
AEC should be kept enabled for normal operation.
To disable Noise Cancellation (NC)
1. Click Advanced .
2. Click NC to disable noise cancellation.
Note: Noise Cancellation prevents ambient or background
noise from being sent to the far-end. ClearOne
recommends keeping NC enabled.
