2. GENERAL DESCRIPTION

The TOA TS-800 Series is a cordless infrared conference system that can be installed and removed quickly and easily. Since the TS-801 Chairman unit and the TS-802 Delegate unit require no wiring, they permit easy installation based on a free layout. The Infrared Transmitter/Receiver unit and recording equipment are connected to the TS-800 Central unit, and the system function settings and status indications are performed at the Central unit.

3. FEATURES

•Since the system is cordless, it can be easily installed and removed, permitting flexible relocation and changes in system layout.

•The system's infrared communication method is not only resistant to radio interference and eavesdropping, but it also permits simultaneous use of systems in adjacent conference rooms with no crosstalk.

•The number of Chairman and Delegate units can be varied as required depending on the number of participants. Up to 64 Chairman and Delegate units can be used per system.

•The maximum number of Infrared Transmitter/Receiver units to be installed in a system is 16 when they are all TS-905 units and 12 when they are all TS-907 units. (Also 12 when both models are mixed.)

•A function to restrict the number of speakers minimizes disorder that could result from simultaneous communications by meeting participants.

•The speech system selection function permits operation when the unit's Talk key is pressed to be set to first- in-first-out, last-in-first-out, or other priority.

•The Mic-Off function automatically turns off the unit's microphone after 30 seconds, even if a user forgets to turn off the microphone after speech completion.

•While the Chairman or Delegate unit is in use, its built-in monitor speaker is turned off, preventing acoustic feedback*.

•The Central unit can be used in conjunction with wired microphones and output source equipment, depending on application.

•Since the Central unit can be connected to recording equipment, it is ideal for use in preparing conference minutes.

•The Chairman unit features a priority speech key which allows it to take precedence over Delegate units when speaking.

•The dedicated microphone used by Chairman and Delegate units employs an XLR connector that not only permits easy attachment and detachment of the microphone, but also saves space when stored.

•Both Chairman and Delegate units can be operated on both their built-in rechargeable lithium-ion batteries or AC power supply.

•Two types of dedicated microphones are made available for the Chairman and Delegate units: "standard" and "long."

* Acoustic feedback: A squeal or howl from the speaker caused by an audio loop condition in which part of the speaker output is picked up by the same microphone, and subsequently amplified and output from the speaker again, quickly building in intensity.
