Infrared Wireless Conference System
TS-900/800 Series
Installation made easier than ever thanks to infrared system coupled with clear sound amplification. Wireless conference system provides flexible adaptation to diverse styles of conference.
Infrared communication system contributes to smoother management of medium to small-scale conferences
Higher security with infrared communication
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.
Easy installation
Infrared communication system eliminates the need of connecting the conference units. Installation can be done quick and smart without cumbersome cable arrangements.
Easy connection with a single coaxial cable
Central unit and Infrared Transmitter/Receiver unit can be connected using a single coaxial cable.
Flexible adaptation to change of the number of participants or layout
Up to 96 Chairman and Delegate units can be used per system for TS-900 Series (up to 64 Chairman and Delegate units for TS-800 Series). Cordless and easy-to-relocate feature makes the system ideal for any conference apt to change the number of participants or layout.
Compact light-weight Chairman/Delegate units
Microphone, monitor speaker, Talk key and Speech indicator are totally integrated. When the unit’s Talk key is pressed, the Microphone indicator lights up to enter the mode accepting a speech. Microphone is removable for compact storage.
Clear sound amplification and recording
The Chairman and Delegate units have a built-in monitor speaker which makes talker’s voice clearly audible at seat. When recording equipment is connected to the Central unit, clear recording is possible which is indispensable in preparing conference minutes.
Selectable power supply system
Both Chairman and Delegate units can be operated on either their built-in rechargeable lithium-ion batteries (for approx. 10 hours use) or AC power supply. Battery charger can recharge up to 8 lithium-ion batteries at a time in about 5 hours.
Adjustable to broader area use
Up to 16 Infrared Transmitter/Receiver units can be connected to expand the area of infrared communication coverage using a distributor.
* Up to 4 Infrared Transmitter/Receiver units can be directly connected to the Central unit. Distributors are needed in order to connect 5 or more Infrared Transmitter/Receiver units.
Capability of manipulation from PC or console (customized)
Using the customized software, it is possible to control the system from PC or console to perform recording, giving permission of speech, and other operations.
Other features
The Chairman units features a priority speech key which allows it to take precedence over Delegate units when speaking.
Sounds from a wired microphone or sound source equipment can be heard from the Chairman and Delegate units' speakers.
Two types of dedicated microphones are made available for the Chairman and Delegate units: standard(368 mm long) and long(518 mm long).
Besides ceiling or wall mounting, the Infrared Transmitter/Receiver unit can also be tentatively installed on a microphone stand (applicable thread size: W 5/16").

Notes on Installation of Infrared Transmitter/Receiver Unit
Notes on Installation of Infrared Transmitter/Receiver Unit
• Make sure to position the Chairman and Delegate units within the optimal coverage area of the Infrared Transmitter/Receiver unit.
•Infrared light will not reach the Infrared Transmitter/Receiver unit if it is located behind user or other obstacles. Install the Infrared Transmitter/Receiver units in such a way that two or more units are visible from the Chairman and Delegate units.
•With only one Infrared Transmitter/Receiver unit used for communication, the reception can be interrupted if infrared signal is obstructed by a person or an obstacle. Install two or more Infrared Transmitter/Receiver units so that the Chairman and Delegate units can communicate with them at all times.
• Do not install the Infrared Transmitter/Receiver units close to the wall or an obstacle.
•Install the Infrared Transmitter/Receiver units at least 2-3 meters away from the nearest window. Cover the windows with curtains or blinds to keep the units free from direct sunlight.
• Position the units at least 50 cm away from fluorescent lights.
• Keep away other infrared light sources. Lighting equipment, LCD projectors, overhead projectors, incandescent lamps, mercury-arc lamps, plasma displays, remote controllers, infrared microphones, infrared equipment such as infrared LANs, dimmers.

Distributor use
• Avoid connecting more than 2 distributors in series. Connecting 3 or more distributors increases high frequency signal loss, and could result in system malfunction.
• It is possible to mix Infrared Transmitter/Receiver units not connected to any distributor, those connected to 1 distributor, and those connected to 2 distributors in the same system.

If two or more Infrared Transmitter/Receiver units with different connection cable lengths receive infrared signals from the Chairman and Delegate units, the signal reception level may decrease to cause malfunction.
• Ensure that the cable length between Infrared Transmitter/Receiver unit and Central unit is identical.
Cable length between each Infrared Transmitter/Receiver unit and Central unit: L=A+B=A+C+D
*This length must always be the same even if a distributor is in

or: D
Conditions for finding maximum cable length
The maximum cable length between each InfraredTransmitter/ Receiver unit and the Central unit differs depending on the type of coaxial cable used. The following two requirements must be met. The shorter length of the two results is considered to be the maximum length allowed. Do not exceed the maximum cable length.
1. Maximum allowable cable loss: 20 dB _ Total distributor loss (varying with type of distributor and the number of serially-connected distributors)
2. Maximum allowable cable DC voltage drop: 5 V
*For more details, please contact your dealer.
