A Buddhist university in Myanmar needed a professional wireless conference audio system for its multifunctional conference room, where 23 participants speak around a large U-shaped table. The room also serves other campus purposes, so the system had to work reliably in a genuinely multi-purpose environment.
Client Requirements
The university set out clear requirements: full-featured operation, adaptability to a multifunctional meeting environment, and the ability to connect with many different types of equipment. Interference immunity was a top priority — mobile phones and other wireless devices in the room must not interrupt the meeting. Sound had to stay stable, continuous and free of noise, and the installation had to be simple, space-saving and completely harmless to the existing venue.
Solution
After comparing several options, the client chose the Relacart WDC-903 Dante digital wireless conference discussion system, configured with 2 WDC-903C chairman units and 21 WDC-903D delegate units.
The WDC-903 works in the UHF band and provides strong anti-interference performance, effectively isolating the impact of the surrounding meeting environment. Its built-in Dante interface allows audio transport to and from any Dante-enabled device, and it can be combined with the VTS-2000 automatic video tracking system and central control systems, giving it the expansion capability a multifunctional room demands. Because the whole system is wireless, installation is quick and leaves the venue untouched.
System Highlights
- LoRa 433 MHz wireless control signaling combined with UHF audio transmission
- Automatic search for interference-free channels and automatic replacement of affected ones
- Support for up to 255 wireless discussion units, with a maximum of 5 units speaking simultaneously
- Dante interface for audio exchange with any Dante-enabled equipment
- Strong immunity to interference from computers, mobile phones and Bluetooth devices
- Automatic or manual power-on for the discussion units — in automatic mode the main unit sends a start command and every unit powers up into working mode by itself
- Four conference modes, plus compatibility with the VTS-2000 automatic video tracking system and central control systems for modern, multifunctional meetings
The WDC-903C chairman unit and WDC-903D delegate unit are powered by detachable lithium batteries, charged either in the dedicated WDC-903 charging case or directly through the USB port of the unit. A fully charged battery delivers up to 23 hours of continuous speaking, 48 hours of standby, and — with the automatic microphone-on option enabled — up to 90 days of readiness. A bright OLED display shows battery level, speaking mode and speech timer settings, and the units maintain strong resistance to mobile phone interference.
The Relacart VTS-2000 video tracking system can be paired with any Relacart conference system equipped with camera tracking. When a discussion unit switches its microphone on, the camera automatically tracks the position of the speaker and shows them on the connected video display, and a dedicated frame-freeze function further refines the automatic tracking experience.
With 2 chairman units and 21 delegate units in service, the WDC-903 Dante digital wireless conference discussion system provides clear sound and rich expansion capability for different meeting scenarios. Its easy installation and simple operation remove unnecessary steps from everyday meetings, and the wireless conference audio system has won unanimous recognition from the client. Relacart systems of this class are widely used in government facilities, corporate meeting rooms, business venues and international conference centers.
