729604 - Overview

The Beyerdynamic wireless semi-cardioid Quinta TB boundary microphone with a highgain-before feedback complements the Quinta conference system. The microphone is provided with a three-colored backlit microphone button containing a braille inscription to turn the microphone on or off. The microphone has integrated transmitting and receiving antennae (antenna diversity) in a high-quality housing of synthetic material with a black soft touch surface and a microphone grille in stainless steel look. With the Automatic Channel Allocation function, the transmitting channels of the microphone units / boundary microphones are allocated automatically. When the microphone button is pressed in the manual operating mode, the request-to-talk is received by the control unit (a possible external dual color LED will illuminate red). The control unit checks which of the available receiving channels is free, then the control unit informs the microphone unit / boundary microphone which channel it should use for transmitting. When the channel of the microphone unit/boundary microphone is set and checked by the control unit, the microphone is switched on. The ready-to-talk status of the microphone is also indicated by the green lighting microphone button. In the Request-to-Talk-mode of the discussion system the request-to-talk is received, but the microphone is not switched on. The red lighting microphone button indicates that the request-to-talk has been received. The microphone is switched on by the operator at the PC by using the "Quinta Conference" software or a media control system. When the microphone button is pressed once again, the delegate clears his/her request-to-talk.
