The Parts Division of GAC Group, dedicated to producing automotive accessories and components, has grown into one of the largest and most influential automotive parts companies in China, ranking fifth among China's top 100 automotive parts companies in 2007. Recently, the division decided to upgrade its conference room equipment, and after an in-depth evaluation it chose Relacart, a Chinese audio manufacturer with 32 years of R&D and production experience (est. 1994), building the system with the WDC-903 wireless conference discussion system and the CS-302 wired professional digital conference discussion system.
Project Challenges
- Many types of meetings: the room hosts various meetings with many participants every day, so the system must be full-featured yet simple to operate.
- Wired + wireless combination: the room is divided into two parts — the central conference table can use a more stable wired system, while cabling the surrounding seats is difficult, so the solution must combine wired and wireless.
- Interference from various devices: with many devices in the room, the microphone system must stay stable and sound clear so that no meeting is disturbed.
Solution
The conference room consists of a large central conference table and surrounding seats. Since the table has built-in cable channels, the CS-302 wired professional digital conference discussion system was chosen for it; the system can control up to 4 cameras via RS-232 or RS-422 serial protocols to build a camera tracking system.
Paired with the CS-N1 wired conference discussion unit, which accepts a variety of interchangeable microphone capsules, the newly developed voice-control mode lets participants start the unit simply by speaking into the microphone — no manual operation needed — making it suitable for all kinds of meetings.
For the surrounding seats, where cabling is difficult, the WDC-903 wireless conference discussion system was selected. Its wireless transmission is equally stable, deployment is faster and easier, and the units can be moved at any time; the WDC-903 also supports an automatic video tracking system for a fully tracked meeting room.
For signal transmission, the system uses Relacart's R-32AU wideband directional antenna, which offers gain settings and easy installation, together with the R-14D two-channel 4-way antenna distributor featuring low intermodulation distortion. It fully supports UHF wideband wireless systems and can serve 2 to 4 Relacart wireless systems of different series at the same time.
Product Introduction
WDC-903 Dante digital wireless conference discussion system: professional appearance, circuit design and stable functionality; works with the VTS-2000 automatic video tracking system and central control systems for versatile, high-tech meetings. Control data is transmitted over the LoRa protocol while audio works in the UHF band; the high-fidelity circuit design delivers high-quality sound.
CS-302 wired professional digital conference discussion system: a simple, cost-effective discussion system with a refined design, built for all kinds of meeting applications as a daisy-chain discussion system. Its voice-control mode lets participants start the unit simply by speaking, with no manual operation required.
Exquisite quality witnesses excellence. Relacart will keep refining its technology to bring more quality products and solutions to customers in the automotive industry and beyond.
