Brähler adds VOX to Digimic

AUTHOR: Inavate

Brähler ICS Konferenztechnik has added selectable variable voice activation (VOX) to its Digimic product line.

The VOX mode allows automatic microphone on/off functions to be voice activated, paving the way for hands free operation.

Two operating modes may be selected. One is the limitation of microphones, which will be open parallel (VAL). Second is an unlimited number of open microphones (VAU). In both modes the “push to talk” button becomes a “mute” function to prevent bidirectional communication with the neighbour. In both modes the chairman may also be activated. Within these operating modes the sensitivity and decay time parameters are adjustable. The sensitivity threshold sets the response time of the microphone as it relates to the person speaking. The decay time determines how long the microphone remains active after the participant has finished speaking. Default settings are provided and are sufficient for most applications.

The second voice activation setting (VAU) may also be used for courtroom applications. All functions are the same as the standard voice activation (VAL) but for courtrooms some additional features are available.

Furthermore, the Chairman unit (DChair) is detected automatically, by using the “mute” button all microphones will be muted and it can send a “noise” signal to a specified output on the central control unit (DCen) and resulting in an existing audio signal being replaced.

The VOX-modes may be used in the autonomous (DSpark) and / or in the “slave” combined system (DCen) operation. Any changes within the setting procedure are active immediately. The VOX-modes are available throughout the entire DIGIMIC product line.
