Technology Empowering Environmental Protection: Hishico Sound Reinforcement System Supports the Upgrade and Renovation of the Conference Room at the Hantai Branch of Hanzhong City
Foreword: When Environmental Protection Meets Technology
As the wave of digital transformation sweeps across all industries, government meeting systems are also seizing the opportunity for intelligent upgrades. Recently, the conference room at the Hantai Branch of the Hanzhong Municipal Bureau of Ecology and Environment successfully completed an upgrade of its sound reinforcement system, adopting an advanced solution from Hishico, a well-known domestic audio-visual brand. This upgrade has not only improved meeting efficiency but has also set a benchmark for the digital advancement of environmental protection efforts.
Project Background: What Kind of Sound Is Needed for an Environmental Conference?
As a key functional department for local environmental protection, the Hantai Branch of the Hanzhong Municipal Bureau of Ecology and Environment is responsible for important duties such as environmental monitoring, law enforcement oversight, and policy outreach. Its conference room serves as a vital venue for daily work meetings, the dissemination of environmental protection policies, and briefings on law enforcement activities, and therefore places extremely high demands on the audio system:
• High clarity: Environmental protection terminology and data reports must be conveyed accurately
• High reliability: Technical failures are not tolerated during important meetings
• Good compatibility: Must support multiple meeting formats (on-site meetings, video conferences, etc.)
• Environmentally friendly and energy-efficient: Aligns with the green office philosophy advocated by the ecological and environmental authorities themselves
Hishico Solutions: Professional Audio-Visual Technology Empowering Eco-Friendly Conferences
As a leading domestic manufacturer of professional audio-visual equipment, Hishico provided a comprehensive sound reinforcement system solution for the conference room at the Hantai Branch, primarily consisting of the following core components:
One-to-Eight Wireless Gooseneck Microphone (OBK-528HZ):
• Operates in the UHF 520–930 MHz band to avoid interference frequencies
• Fully automatic infrared frequency pairing ensures the transmitter and receiver automatically synchronize for transmission and reception
• Features a phase-locked loop (PLL) frequency synthesis stabilization system, providing 200 channels
• Incorporates the latest high-frequency filter to maximize the elimination of out-of-band interference signals
• Multi-stage noise suppression control circuitry to block external interference
Professional Power Amplifier (OBK-300EX):
• Cooling System: Dual variable-speed fans with front-to-rear airflow
• Equipped with comprehensive protection circuits (short-circuit, overload, and overheat protection)
• The EX system’s amplifier circuitry has been comprehensively optimized and fine-tuned based on advanced, proven Class AB and Class H circuits
Digital Audio Processor (OBK-MA880S):
• USB plug-and-play software; also supports RS232 central control
• Supports operation and control via mobile and tablet apps for iOS, iPad, and Android
• Supports an external wired control panel; multiple panels can be controlled simultaneously
• Supports sensitivity adjustment; each analog signal input can be adjusted in 9 levels via the software
Suppressor (OBK-224B):
• Flexibly adjustable notch filter with powerful independent channel functions, including gain, noise gate, and compressor
• 48 LEDs provide real-time display of notch filter status
• Features one-button rotary control for quick access to mode selection, bypass, lock, and Chinese/English language selection
Results of the Renovation: A Comprehensive Improvement in the Meeting Experience
After the system was put into use, the audio experience in the Hantai Branch’s conference room took a quantum leap:
1. Improved Audio Clarity: Participants have reported that they can now clearly hear every detail of what is being said, regardless of where they are seated in the conference room. In particular, the recognition rate of numbers has significantly improved during reports on environmental monitoring data.
2. Improved Meeting Efficiency: Smart meeting management features ensure a smoother meeting process, reducing the average meeting duration by 15%.
3. Enhanced Ease of Use: The one-click interface allows even non-technical users to easily control the entire meeting’s audio.
4. Reduced Maintenance Costs: The system’s modular design enables quick and accurate fault diagnosis, making maintenance much simpler.
Outlook: Technology Drives New Developments in Environmental Protection
• As environmental protection efforts continue to advance, information technology and smart solutions will become key tools for enhancing environmental protection effectiveness. As a fundamental platform for the daily operations of environmental protection agencies, the upgrade and modernization of conference systems serves as a model for others to follow.
• A representative from Hishico stated, “We are honored to contribute our part to the cause of environmental protection. In the future, we will continue to deepen our expertise in audio-visual technology to provide high-quality conference experiences for more environmental protection agencies, thereby supporting the construction of a Beautiful China.”
• The successful implementation at the conference room of the Hantai Branch of the Hanzhong Municipal Bureau of Ecology and Environment demonstrates that professional technical equipment can effectively improve government agencies’ operational efficiency and public service standards. Amid the digital transformation, the integration of technology and environmental protection will spur more innovative applications, providing robust support for the development of an ecological civilization.
