Infrared radiators providing wireless transmission of up to seven language channels for persons (e.g., observers) listing to a conference without asking for the floor.
The infrared radiators shall connected to the CS 5 BU through 2 BNC connectors and 50 Ohm coaxial cabling and serial concatenation. It shall transmit a PPM system modulated time-multiplex outputs of the central unit shall drive an arbitrary number of radiators. The CS 5 IRT1 shall have a radiation angle of +/- 22° and a working distance of 300 meters (with 50% down). The CS 5 IRT2 shall have a radiation angle of +/- 22° and a working distance of 500 meters (with 50% down).
As accessories of the infrared radiators the holding frame needed for mounting it to the side wall or the ceiling shall be included. The transmitter shall have a built in switchable power supply with IEC connector.

Supplied ceiling-mounting brackets facilitate installation.
Equipped with power indicator LED.
The IR-510R covers a practical radius of approx. 8 m.

- System Features and Outline
- Bilingual conference system. Either English interpretation (main audio) or Japanese interpretation (sub audio) is selectable for monitoring.
- Operations such as giving speech permission can be done from the operation PC. *Custom design.
- The number of conference units can be set for any of one, two or four persons allowed to talk at a time.
- All speeches during the conference can be recorded clearly.
- Sub audio(Japanese interpretation) is not recorded.
- Threefold choice vote function enables the voting just at the press of a Vote key on each unit. The result can be instantly totalized on the Central unit.
- Speeches can be addressed to audience via sound amplification. * The sub audio output is not amplified

- Base Station for up to 200 Microphone Stations
- Intuitive controls
- Superior audio quality
- Voice activation and NOM limitation
- Standard ins and outs for external equipment
The CS 2 Base Station controls up to 200 Microphone Stations and provides automatic NOM (Number of Open Microphones) attenuation. System gain will decrease by approx. 3 dB every time the number of open microphone doubles. The result is a substantially lower risk of feedback even if the number of open microphones varies constantly.
A selectable Voice Activation function turns the microphones on automatically as soon as they are talked into.
The NOM Limitation function allows the number of simultaneously open microphones to be limited to one, two, three, four, or five. This function can be locally disabled on each Microphone Station so a specific microphone, e.g., one mounted on a lectern, will come on every time, no matter how many mics may be open already. |
