TS-820

The TS-820 is a Central Unit of the Infrared Conference System that allows easy installation and flexible layout. By connecting TS-905/907 IR Transmitter/Receiver, TS-820 can control the Chairman and Delegate Units via wireless infrared signal. It features the installation confirmation function that allows the connection status of IR Transmitter/Receiver and Chairman/Delegate Units to be verified. The TS-820 is also equipped with FBS (Feedback Suppression), enabling effective control of acoustic feedback. The system can be controlled by PC (*1). With the use of an optional rack mounting bracket, it can be mounted in an EIA Standard equipment rack (4 unit size).
