The Quinta CU control unit is used to control about 150 wireless microphone units with loudspeakers. Depending on the settings and selected operating mode up to 4 microphone units can be turned on simultaneously (e.g. 3 delegate and 1 chairman microphone unit). There is a constant status inquiry, monitoring or control due to the data connection to the microphone units. Individual microphone units can be activated via the RS 232 serial interface. The complete discussion system can be switched off via a control command or by pressing the “Stand-by” button on the front. The 4 LEDs on the front indicate the assigned transmission channels of the microphones. For maximum security the control unit can be protected with a PIN code accepting only microphone units that have the correct PIN code. In addition to this, the radio transmission is digitally encrypted.

The Quinta system meets the regulations of the European Telecommunications Standards Institute (ETSI) and can be integrated into existing or new building computer networks that comply IEEE 802.1 IT standard (AVB). For a safe wireless transmission there are three frequency bands available: 2.4 / 5.2 / 5.8 GHz. The switching of the channels is either automatically or manually. The protection against unauthorised listening is guaranteed by using 128-bit encryption and a 24-bit PIN-code. The integrated Web server allows configuring the control unit with a Smartphone, tablet PC or PC via USB, LAN, WLAN. The system can be connected to a media control system via the RS 232 interface. This allows a particularly convenient operation and provides different status indicators e.g. the battery status. Furthermore, the Quinta system can be integrated into tele and video conferences.


  • DSSS modulation to ensure high immunity from interference in the frequency range of 2.4 / 5.2 and 5.8 GHz
  • HD - High Definition audio mode provides an audio bandwidth of 24 KHz and a sampling rate of 48 KHz
  • HQ - High Quality of service mode for a user-optimised transmitting and receiving performance in difficult environments in terms of radio transmission
  • AVB (Audio Video Bridging) input and output for digital signal transmission in building networks - compliant to the IEEE 801.1 standards
  • True diversity antenna technology ensures highest transmission and reception reliability
  • Digital 128-bit encryption and additional 24-bit PIN code protection
  • Automatic recognition of interferences in all frequency ranges

  • NOM - Number of open Microphones function allows the allocation of up to 4 microphone units simultaneously
  • Processor-controlled and automatic audio channel allocation of the microphone units
  • Different operating modes:
      -  Manual – each participant can turn the microphone on and off;
      -  Voice Activation – the microphone is turned on when someone speaks into it;
      -  Override – when a microphone unit is activated, the one that was activated before will be turned off;
      -  Push-To-Talk – as long as the participant speaks into the microphone, he/she must press the microphone button.
  • Integrated DSP for flexible audio routing
  • Zoning – the output channel allocation of individual microphone units can be divided into 4 different audio zones analogue or digital via AVB
  • With the Mix-Minus function the system can be integrated into tele- and video conferences
