Description

The Quinta MU 31 delegate microphone unit is equipped with a microphone button in the housing with which the participant can switch his microphone on and off. Additionally the unit features two buttons to adjust the level on the headphone output. The Revoluto microphone array technology with integrated microphone capsules provides a so-called corridor characteristic which ensures a wide range of good voice quality.

The speaker can move freely, i.e. can stand up or sit down, can move his/her head and move towards or away from the microphone unit. The ready-to-talk status of the microphone is indicated by the red LED strips on both sides of the housing. 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 must be 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. The parameters of the microphone unit are adjusted via PC by using the “Quinta Conference” software.

The parameters are set for all microphone units. The volume of the loudspeaker is adjusted and can be controlled with the Quinta control unit or a media control system. Each microphone unit has its own address. An existing system can be complemented at any time.
