InfoComm USA 2025 is in full swing, and Relacart proudly presents its flagship product—the WDC-943 Array Wireless Conference System—at the Orange County Convention Center in Orlando. With three core strengths—robust anti-interference, sleek invisible aesthetics, and ultra-simplified deployment—Relacart showcases how intelligent manufacturing from China is redefining the premium meeting experience on a global stage.
Frequency Backup Technology
The WDC-943 features intelligent frequency backup, continuously scanning for clean frequencies. If the current frequency encounters interference, the system automatically and seamlessly switches to a cleaner channel, ensuring uninterrupted wireless transmission—even in the most congested RF environments.
LoRa Communication Protocol
The system utilizes a 433 MHz LoRa protocol for control signals, offering low power consumption and long-distance, highly stable signal transmission for smooth and reliable operation switching.
Flush Desktop Design
With its low-profile, streamlined housing, the WDC-943 sits seamlessly on tabletops. The no-gooseneck design eliminates visual clutter and removes pressure from participants, while keeping faces unobstructed during video capture.
Beamforming Microphone Array
Featuring advanced microphone array technology, the WDC-943 provides an extended 80cm pickup range and enhanced directional sensitivity. Compared to standard cardioid mics, it delivers deeper, more focused voice capture with superior clarity.
Ultra-Simplified Deployment: Faster Setup, Smarter Control
Dante Audio Network Support
Fully compatible with the Dante audio protocol, the WDC-943 supports low-latency, high-fidelity digital audio over a single Ethernet cable. Integration and troubleshooting are streamlined via Audinate Dante Controller software, making deployment and future expansion effortless.
One-Touch Power Control
The system allows centralized control to power on/off all units simultaneously. Entire meeting setups can be ready in as little as 30 seconds, dramatically reducing setup time and manual workload.
Proven Performance: Deployed at China Railway Zhangjiakou Division
The WDC-943 has already proven itself in mission-critical environments such as the China Railway Zhangjiakou Division, where stability and audio performance are paramount.
