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

The WDR69M is the receiving station for the WDR69 wireless conference system; it manages and coordinates communication between the "Chairman" and "Delegate" microphone units. It operates in the 600 – 928 ​​MHz band, a universal ISM frequency compliant with international CCC, CE, ROHS, and FCC standards, ensuring compatibility, reliability, and high resistance to interference. The station manages up to 60 channels, allowing the simultaneous operation of one "Chairman" unit and three "Delegate" units, with no limit on the total number of delegates that can be connected in FIFO mode. The WDR69M supports first-in, first-out (FIFO), and request-to-speak conferencing modes, allowing for orderly management of speaking sessions. Communication occurs via dual transmission channels, ensuring stable exchange between the base and desktop units. A battery detection system indicates critical battery levels via LEDs on the conference units, while digital frequency-shifting technology ensures a clear, stable, and feedback-free tone. The station's operating range generally varies between 25 and 30 meters, depending on the room's characteristics. Digital transmission offers numerous advantages: particularly effective anti-interference (without interference from nearby laptops or devices), low noise, a high signal-to-noise ratio, and improved receiver dynamics. Connected units can operate for up to 5 hours continuously and remain in standby for up to a week, ensuring continuity even in intensive use.
