Anyone who wants to speak must press a button on their delegate unit. There is also a chairman unit in the discussion system, which always has priority. The person in charge of the debate receives this unit. If simultaneous interpreting is provided, it is possible to listen to the selected language version directly from the discussion unit.
The number of active microphones can also be configured simultaneously in different operating modes:
- OVERITE – intercepting the voice of the first speaker
- OPEN – open mode, waiting list in the debate
- VOICE – voice activation mode
