I. Project Overview:
• Located in Xi’an, a historic city in China, this project aims to build a multimedia conference system integrated with intelligent technologies. The design adopts a suite of high-end technical solutions including high-definition seamless hybrid matrix systems, professional sound reinforcement systems and digital conference discussion systems, supplemented by an intelligent central control system to manage these sophisticated technical components. Beyond daily conferences, the system supports multi-functional scenarios such as training sessions.
• Great efforts have been invested in ensuring the industry-leading stability of the conference system to maintain consistent performance during long-hour operation. Meanwhile, comprehensive optimizations have been made to system functions. While delivering an efficient and user-friendly conference experience, the project guarantees complete, reliable system performance. Through all-round, high-standard technical investment, this project creates a modern, professional conference environment for the enterprise.
II. Project Requirements:
The conference room is designed to meet the following objectives:
1. Achieve optimal cost efficiency through optimized design while ensuring advanced, reliable and cost-effective system performance to save corporate resources.
2. The sound reinforcement system shall comply with national standards for language sound reinforcement, delivering bright and intelligible speech. All design indicators shall follow the Code for Design of Hall Sound Reinforcement Systems (GB/T 28049-2011).
3. Equipped with high-end acoustic positioning technology, the system realizes precise spatial identification without tilt or deviation errors. The technology significantly improves measurement accuracy and repeatability, satisfying strict precision and stability requirements for professional scenarios.
4. The sound reinforcement system supports convenient wireless handheld speech functions.
5. The sound reinforcement system features high-sensitivity conference discussion microphones, with a priority speaking function for the chairman unit.
6. The system enables seamless audio and video signal switching to accommodate multiple signal sources for diverse usage scenarios.
7. The fully integrated system centralizes control of lighting, large-screen displays, audio and video equipment. Users can activate pre-programmed conference modes with a single tap on a tablet computer, streamlining operation procedures for ease of use.
III. Solution:
1. Professional Sound Reinforcement:
Three prerequisites are required for premium hall sound reinforcement audio quality:
1) Optimized architectural acoustic environment
2) Reasonable audio system configuration
3) Scientific commissioning of the sound reinforcement system
• In modern commercial and professional environments, conference room sound quality is critical for effective communication. Our professional conference room sound reinforcement solution is engineered for vocal clarity, sound fidelity and ease of operation, catering to conferences of all scales and types. The solution incorporates carefully selected advanced audio equipment and professional installation & commissioning to ensure uniform sound coverage across the venue, delivering crisp audio transmission and smooth interaction for both in-person and remote communication. Supporting multiple media input sources and featuring intuitive operation, the solution provides exceptional listening experience for all conference rooms and improves overall meeting efficiency.
2. Central Control Matrix System:
• In today’s fast-paced commercial landscape, effective conference room management is an indispensable part of corporate operations. To address this demand, we propose an integrated conference room central control matrix solution. Leveraging advanced central control technology, the system realizes centralized management of all multimedia equipment in the conference room, including projectors, audio systems, intelligent lighting, curtains and other environmental facilities. Users can perform one-touch operations to switch conference modes effortlessly, streamline meeting workflows and boost conference efficiency.
• Core advantages of the solution include high professionalism and customization capabilities, enabling tailored conference control systems for enterprises with unique demands. Additionally, the system boasts strong expandability for seamless future upgrades or integration of new equipment and functions. Safety and stability are prioritized to guarantee secure information and uninterrupted system operation during conferences.
• Deploying the conference room central control matrix solution significantly enhances the professionalism and efficiency of corporate conference management, helping enterprises maintain a competitive edge in fierce commercial competition.
• The conference room is equipped with diverse signal sources of varying resolutions. To facilitate signal switching between DVD players, laptops, stage floor sockets, cameras and display screens, a seamless hybrid matrix system is deployed and connected to the central control system for unified management via iPad tablets.
• As video systems evolve from standard definition to high and ultra-high definition, video source and display devices adopt diverse encoding technologies and interfaces. A dedicated matrix system is required to enable arbitrary combination switching between numerous input signal sources and output display devices. This seamless hybrid matrix system is independently developed by Hishico for signal conversion, transmission and processing, completely eliminating compatibility issues caused by multi-brand equipment integration.
IV. Customer Feedback
Senior leaders of the project operator highly praised the advanced performance and ease of use of the new conference room system. They commented that microphones transmit full, layered audio with high sound restoration fidelity, ensuring perfect audio-video synchronization with large-screen displays. Furthermore, the system incorporates directional sound propagation design, creating an immersive auditory experience where sound appears to originate directly from the front regardless of seating position. Even when participants sit far apart, the sound reinforcement system delivers intimate, natural communication as if all attendees are face-to-face. The advanced conference equipment not only improves communication efficiency but also greatly elevates the overall conference experience.
