The Quinta MU 22 delegate microphone unit is equipped with two microphone buttons in the housing so that two participants can share one microphone unit. The operating software can differentiate who is to speak.

With the Automatic Channel Allocation function the transmitting channels of the microphone units are allocated automatically. When the microphone button is pressed in the manual operating mode the request-to-talk is received by the control unit (a possible external dual colour LED will illuminate red). Then the control unit checks which of the available receiving channels is free. Then the control unit informs the microphone unit which channel it should use for transmitting. When the channel of the microphone unit is set and checked by the control unit, the microphone is switched on. The ready-to-talk status of the microphone is also indicated by the red LED ring around the gooseneck microphone. In the Requestto- Talk-mode of the discussion system the request-to-talk is received, but the microphone is not switched on. The red LED indicates that the request-to-talk has been received. The microphone is switched on by the operator at the PC by using the
“Quinta Conference” software or a media control system. When the microphone button is pressed once again, the delegate clears his/her request-to-talk.

Depending on the configuration with the “Quinta Conference” software the following operating modes are available: Override: the first microphone is switched off, when the maximum number of switched on microphones is exceeded. Voice activation: the microphone is switched on, when someone speaks into it. Push-To-Talk: the microphone button is held down, while the participant is speaking.

The integrated loudspeaker reproduces the audio signal of the whole conference system. Depending on the audio signal routing in the control unit the loudspeaker can reproduce other audio signals such as a wireless microphone in the auditorium.
