PA System Installation at Wisma MCA | Dewan San Choon
Dewan San Choon, located within Wisma MCA in Kuala Lumpur, is one of Malaysia’s most recognized multi-purpose halls. The venue regularly hosts corporate conferences, award ceremonies, cultural events, and live performances, making it a landmark facility in the city’s event scene.
Designed to accommodate hundreds of guests, the hall features a spacious stage, tiered seating, and a flexible floor layout suitable for both formal gatherings and entertainment functions. However, with such a large and dynamic environment, achieving consistent sound coverage, speech intelligibility, and system control across the hall can be challenging — especially during hybrid or multimedia-heavy events.
To address these needs, the client engaged Vbizz to design and install a comprehensive PA system that could deliver crystal-clear audio, reliable operation, and easy user control, while integrating seamlessly with the venue’s existing lighting and AV infrastructure.
Our Solution
To meet the venue’s diverse event requirements, the Vbizz engineering team designed and implemented a comprehensive PA system tailored specifically for Dewan San Choon’s large hall environment. The primary objective was to achieve even sound distribution, high speech intelligibility, and reliable system control across all seating areas.
A professional-grade line array speaker system was installed to deliver powerful yet balanced audio coverage from the stage to the back of the hall. This setup minimizes echo and ensures clear sound projection for both speech and live performances. Complementing the line array, strategically positioned subwoofers and front-fill speakers enhance low-frequency response and audience immersion.
At the control area, a digital audio mixer and amplifiers were configured to handle multiple input sources, from microphones and instruments to playback devices. The system allows precise tuning, equalization, and scene recall, ensuring that operators can easily adapt to different types of events.
In addition, the conference and control interface was designed for intuitive operation, enabling event coordinators to manage volume levels, microphone activation, and zone controls effortlessly. The installation also integrated with the hall’s existing lighting system, creating a cohesive AV environment suitable for conferences, concerts, and public functions.
Through careful calibration and testing, the new system provides consistent audio clarity throughout the hall — from the front stage to the upper seating rows — making Dewan San Choon better equipped to host high-profile events with confidence and professionalism.
System Handover & Training
After the installation and calibration were completed, the Vbizz technical team conducted a comprehensive system handover and user training session with the venue’s management and technical staff. The goal was to ensure that every operator could confidently manage the mixer, amplifiers, microphones, and control interfaces without external assistance.
During the session, our engineers demonstrated how to power up and shut down the system safely, adjust input levels, mute or activate microphones, and fine-tune sound balance depending on the event type — whether it’s a formal conference, musical performance, or hybrid meeting. The training also included guidance on basic troubleshooting procedures and maintenance best practices to ensure long-term system reliability.
To make daily operation easier, preset scenes and configurations were programmed into the mixer, allowing users to switch between different event modes with just a few simple controls. This ensures consistent sound performance even when operated by non-technical personnel.
By the end of the handover, the Dewan San Choon team had a clear understanding of their new system’s capabilities — combining ease of use, professional control, and dependable performance. This final stage of the project reinforced Vbizz’s commitment to delivering not just installation, but complete end-to-end AV solutions that empower clients to manage their own systems confidently.
The PA system upgrade at Dewan San Choon, Wisma MCA demonstrates how thoughtful design, precise installation, and professional calibration can transform a large venue into a space that delivers clear, consistent, and immersive sound for every audience member. Through this project, Vbizz ensured that the hall’s audio infrastructure now supports a wide range of events — from formal conferences and cultural performances to hybrid meetings and large-scale presentations.
This installation reflects the importance of integrated AV solutions in enhancing communication, engagement, and overall event experience. With reliable equipment, user-friendly control, and expert training, Dewan San Choon is now better equipped to host world-class events with confidence and clarity.
