Product Overview

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, whensomeone speaks into it.
  • Push-To-Talk: the microphone button must be held down, while theparticipant 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.

The DSSS transmission offers high immunity against unauthorised listening with a 128-bit encryption. In addition to this, the conference system including the appropriate microphone units can be protected with PIN code (24-bit). A microphone unit that does not have the correct PIN code will be identified by the control unit and switched off immediately.

The integrated rechargeable battery allows an operation of the microphone unit of 20 hours depending on the amount of participation in the discussion. As soon as the remaining battery time is below a certain threshold of 1 hour, the power on LED on the rear of the microphone unit will flash or if the system is controlled by PC or a media control system, the low battery capacity can also be displayed. The charging time of a completely empty battery is max. 2.5 hours with the integrated processor-controlled charging electronics. Depending on the use of the microphone unit the charging time can be less.

As an option the microphone unit can be powered and charged by a DC power supply adapter.
