1. DLP SYSTEM B-CDMA DIGITAL Wireless Conference SYSTEM

2. 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.

3. 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 Some points of existing Conference System DLP SYSTEM Binary-CDMA Wireless Conference System B-CDMA Product description

4. 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..
