Voice Detection; Voice Activation (Vox) - Shure DDS 5900 Manual

DDS 5900 Digital Discussion System
Using FIFO Mode
First In, First Out (FIFO) mode automatically turns on microphones based on a chronological queue list. This mode
works best if the maximum number of participants is set to one (1), so that the participant must wait to speak until
the other is finished.

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 but-
ton activation. The following settings allow VOX to be customized for the meeting:

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 acciden-
tally activated from a loud noise other than speech.
This setting ensures that at least one microphone is always activated. This is use-
ful for video or audio conferences with echo-canceling equipment.
