Infrared Transceiver


The TS-907 Infrared Transmitter/Receiver of the Infrared Conference system is designed for high ceiling applications. Since the system is cordless, it can be easily installed and removed. Communications between the TS-907 and conference units are performed by means of infrared signals and the TS-907 permits transmit and receive with the Central unit. It can be mounted not only to the ceiling and wall but on the microphone stand.
