Conference system

The WDC-900M system consists of the WDC-900M receiver, the WD-900C chairman transmitter and WD-900D delegate transmitter. It is a highly flexible, hardwired, digital conference system for fixed and mobile conference applications. 

With 83MHz bandwidth, up to 99 channels are compatible without interfering each other. Because of this feature, the about of channels won't be a problem any more. Rechargeable lithium batteries ensure users to operate it for more than eight hours and save money in daily use. The FIFO and chairman prior function provide more flexibility and stability.

It is the best choice for a medium and mobile discussion system, or as a large permanently installed conference system where voting, delegate management, simultaneous translation and language distribution functions are needed.
