Voice Activation (VOX)
In VOX mode, the microphone activates automatically once a participant speaks. The mode is ideal for meetings that are more
conversational, allowing back-and-forth communication that doesn't involve speak requests and button activation. The following
settings allow VOX to be customized for the meeting:
Voice Detection Threshold
Determines the input level (dB) that activates the microphone. Lower settings activate the
microphone with a quieter source, while higher settings require a louder source to activate
the microphone.
Default
0 dB
Minimum
-12 dB
Maximum
8 dB
Release Time
Determines how long a microphone remains active after a participant stops talking. The set-
ting is selectable in 0.5 second increments.
Default
4 seconds
Minimum
1 seconds
Maximum
10 seconds
Book Drop
To ensure that only the speech from a participant activates the microphone, turn on the book
drop feature. This quickly turns off a microphone that has been accidentally activated from a
loud noise other than speech.
Last Mic Stays Open
This setting ensures that at least one microphone is always activated. This is useful for video
or audio conferences with echo-canceling equipment.
Microphone Auto Off
This setting automatically turns off the microphone when the participant stops talking. This setting applies to systems in FIFO,
Manual or Automatic modes. See
