Founded in 1975, Shenzhen Bus Group has grown over nearly five decades into one of the best-performing and best-managed companies in China's public transport industry. To raise internal communication efficiency and service quality, the group recently carried out an upgrade of the audio system in its command management center.
Requirements
The command management center handles complex and critical daily work, so every instruction conveyed by a speaker must be delivered accurately and clearly. Based on the room's usage needs and acoustic characteristics, Relacart tailored a fully functional, clear-sounding and stable-transmission audio system for Shenzhen Bus Group, built around the WDC-903 wireless conference discussion system.
Frequency Backup for Uninterrupted Meetings
A key capability of the WDC-903 is its frequency backup function: the system always keeps one channel scanning the surrounding environment for clean frequencies, and when other channels suffer interference it switches automatically and seamlessly to the clean channel. Even in extreme conditions, normal audio transmission is preserved.
The WDC-903 also supports one-touch startup: the discussion units power on and off together with the main unit automatically, which lightens the daily maintenance workload. Each unit can be adjusted independently to suit the voice characteristics of different speakers and seating positions, and multiple conference modes cover the needs of a wide range of occasions.
System Technology
The WDC-903 wireless conference discussion system features a professional industrial design, well-engineered circuitry and stable performance. It can be combined with the Relacart VTS-2000 automatic video tracking system and central control systems to support versatile, high-tech modern meetings. Data commands are transmitted via the LoRa protocol, audio works in the UHF band, and a hi-fi circuit design delivers high-quality sound.
With the Relacart professional wireless conference discussion system, the command management center of Shenzhen Bus Group has received a brand-new audio upgrade — convenient to operate and clear to hear, exactly what a modern command center needs.
