DIGITAL Wireless Conference SYSTEM

DLP SYSTEM Wireless Conference System avoids other wireless frequencies incoming from the neighbor and automatically selects and uses another 16 frequencies available, which prevents wires from being crossed and interfered. And this system has a structure which replaces frequencies which errors occur a lot with new frequencies real time and controls to prevent interference between frequencies from occurring by monitoring the quality of frequencies even during frequency use.

Synopsis of B-CDMA Wireless Conference systems

Product Descriptions

Binary-CDMA Wireless Conference System features

With the different electric wave, there are interference and collision

Weakness of wiretapping and security system

With Main CCU uses the AC power, it does not

move, and cannot use the whole system

when it is broken

The movement does not move in order to use the cable

high consumption electric power

With frequency of differences in

other equipments ,

there are interference and collision

There is an automatic protection system against interference and collision

The security system is excellent

The compatibility is excellent

It is used without antenna; it is easy to move

There are no collision and interference

Saving electric power

Product description

Functions. The system for chairman’s use a mutes or resets every microphone. . Owing to speaker built-in feature, it is use without a sound device and can be used by connecting to the outside sound system.. It is used free without feeling a limit in space due to no wires. . As main control does need outside power, the whole system can be used outdoors. . A control unit controls monitor volume in wireless and provides audio output.. Uses 10 hours with one-time charge by large-volume chargeable Li-polimer battery.. Chairman types have a mute function which blocks voices, reset function and an automatic-ascending function which automatically turns off the previous speaker’s voice at a time when another speaker enters the conference.. Automatic tracing camera control function to be added in the future.. Manage the Vote function included vote function by LCD display

ㆍ Infrared rays : Communication distance is significantly short, and it can be blocked

when it has interference, and collision.

ㆍ RF : Communication distance is short, and it is impossible to move other places.

ㆍ B-CDMA : Communication distance is very long, and it is possible to move other places

completely.
