Receiving station wireless conference system WDR69 - RONDSON WDR69M RON-02639

The RONDSON WDR69M is the receiving station for the WDR69 wireless conference system, coordinating communication between the Chairman and Delegate microphone units. It operates in the 600 - 928 MHz band on a universal ISM frequency compliant with the international CCC, CE, ROHS and FCC standards, with high resistance to interference. The station manages up to 60 channels and supports the simultaneous operation of 1 Chairman unit and 3 Delegate units. In FIFO mode, there is no limit to the total number of connected delegates.

First-in, first-out (FIFO) and request-to-speak conference modes provide orderly management of speaking sessions. Dual transmission channels maintain stable communication between the base and desktop units. A battery detection system indicates critical levels through LEDs on the conference units. Digital frequency-shifting technology delivers a clear, stable, feedback-free tone. The operating range generally extends from 25 to 30 metres, depending on the characteristics of the room.

Digital transmission provides particularly effective anti-interference performance, with no interference from nearby laptops or devices, together with low noise, a high signal-to-noise ratio and improved receiver dynamics. Connected units can operate continuously for up to 5 hours and remain on standby for up to 1 week. Applications include small and medium-sized meetings, board meetings, municipal council meetings and general assemblies.
