The Beyerdynamic 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 not 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 unauthorized 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.
