The Quinta MU 23 V chairman microphone unit is equipped with a clear, function and a microphone button in the housing with which the participant can switch his microphone on and off; in addition it has a voting option. The chairman microphone unit does not depend on the maximum number of simultaneous open microphones. Unlike the delegate microphone units the chairman microphone unit is not controlled by Automatic Channel Allocation, but has an extra transmitting channel exclusively for the chairman.
The ready-to-talk status of the microphone is indicated by the red LED ring around the gooseneck microphone. Using the clear button all switched-on microphones of the delegate microphone stations are switched off. With the function button there are various configurations possible via the “Quinta Conference” software: Priority “Normal” When the chairman switches his microphone on with the function button and the priority programming “Normal” the switched on delegate microphone units are switched off.
Afterwards the delegates can switch on their microphone and take part into the discussion again, while the chairman’s microphone is still switched on. Priority “Mute” When the chairman switches his microphone on with the function button and the priority programming “Mute” the switched on delegate microphone units are muted as long as the chairman is speaking. If the chairman switches his microphone off, all delegate microphone units that had been switched on before, are switched on again.
Priority “Clear” When the chairman switches his microphone on with the function button and the priority programming “Clear” the switched on delegate microphone units are switched off. The delegates can switch on their microphone again, when the chairman has switched off his. “Function” A command is sent via the RS 232, USB, TCP/IP serial interface from the Quinta CU control unit and a programmed function is carried out via a media control system for instance (e.g. light control).
For the other functions there is also a command sent via the RS 232, USB, TCP/IP serial interface from the Quinta CU control unit Command A/B Two different commands according to the duration of the push: < 1 second = command “Short press string” is transmitted > 1 second = command “Long press string” is transmitted These commands can be set individually with the “Quinta Conference” software.
Audio Mute An audio signal, e.g. from a wireless microphone, can be switched off. This function can be combined with a “Clear” command to switch off activated delegate microphones. Depending on the configuration with the “Quinta Conference” software the following operating modes are available: 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.
