The large lecture hall has long faced challenges such as uneven sound pickup, complex equipment, and inconvenient recording and broadcasting, seriously affecting the on-site experience of corporate training and conference activities. Recently, Soundking Group has tailored an integrated smart audio-visual solution for Ningbo Tuopu Group Co., Ltd. (hereinafter referred to as "Tuopu Group"). This solution integrates immersive sound reinforcement, intelligent recording and broadcasting, IoT control, and professional stage lighting, creating a full-scenario smart ecosystem and completely refreshing users' imagination about the application of large spaces such as lecture halls. After the project delivery, it has won wide acclaim from the leaders and employees of Tuopu Group for its excellent intelligent performance and professional audio-visual experience.
1. Immersive sound reinforcement, from "audible" to "visible"
The Top Group's amphitheater boasts a spacious classroom and a significant seating height difference, making it challenging for traditional sound reinforcement to ensure consistent listening experience at every seat. Therefore, we have equipped it with an internationally leading and domestically pioneering immersive sound reinforcement system. This system, centered around the British CADAC CP32 immersive sound processor and based on FPGA core technology, incorporates advanced HOA algorithms and supports 7-order 32-channel high-precision sound field reproduction, capable of rendering mono, stereo, 5.1, and other audio formats into 3D immersive sound effects in real time. Whether listeners are seated in the front, side wings, or back of the classroom, they can experience a highly immersive direct sound. In terms of system link design, a dual backup transmission scheme with parallel digital and analog signals is adopted to ensure foolproof performance for important meetings and events.
The main sound reinforcement system utilizes the Soundking GL206A 6.5-inch plastic-cased line-array active loudspeaker, which consists of one 3-inch neodymium tweeter compression driver and two 6.5-inch bass drivers, forming a combination with extremely high headroom. Equipped with an internal independent high-power amplifier and DSP, it features smooth frequency and phase response. With a vertical coverage of 10° and a horizontal coverage of 100°, the sound is rich and powerful. When paired with the Soundking GL206SA single 15-inch line-array active subwoofer, it delivers a powerful bass effect.
The surround and overhead effects are powered by Soundking FCL05L two-way passive coaxial loudspeakers. The coaxial drive technology effectively avoids sound interference, significantly enhancing sound clarity, achieving more uniform sound coverage, and more precise positioning of sound image, ensuring an immersive atmosphere in every corner of the lecture hall. The entire system is efficiently driven by Soundking BD series professional digital network amplifiers, and the Soundking DPM1616D digital audio processor performs precise signal tuning.

II. Intelligent recording and broadcasting: enabling information transmission to transcend time and space
To meet diverse needs such as academic conferences and internal training, we have deployed the Soundking VC200SHU-IP HD network conference camera and the Soundking PC-HDR-404 full HD conference recording and broadcasting host to create a professional-grade intelligent recording and broadcasting system. The camera supports 1080P60 full HD video output and 20x optical zoom, capturing clear details of lecturers and blackboard writing. The recording and broadcasting host adopts a pure embedded system, featuring stable low power consumption and supporting simultaneous recording and live streaming of movie channels and resource channels. It can record up to 4K ultra-high-definition video, with 8 layouts and 14 special effects, presenting rich visual effects. It also supports RTMP/HLS live streaming, FTP transmission, and U-disk copying, facilitating the rapid distribution and sharing of course resources, fully meeting the high-quality recording and broadcasting needs of large-scale training in lecture halls, academic conferences, and other scenarios.
III. IoT Management and Control: Simplifying Complexity, Intelligent Operation and Maintenance
The lecture hall needs to accommodate multiple modes such as meetings, training, and activities, with complex equipment and high operational thresholds. The Soundking CT02 IoT edge computing host can centrally manage and control all devices related to sound, light, electricity, video, and communication. Coupled with the Soundking RBGL9 IoT AV equipment power management terminal, it can monitor real-time data such as current, voltage, temperature, and switch status of each circuit. This significantly simplifies the administrator's operation process, making device operation data clear at a glance, and achieving true intelligent operation and maintenance.
IV. Empowering Details, Enhancing with Light and Shadow
To enhance the sound pickup and speech experience, the Soundking MA60 beamforming array microphone supports 360-degree omnidirectional sound pickup, with a maximum pickup distance of up to 20 meters. The speaker can freely move around the podium while the voice remains clear and natural. The Soundking PT10 intelligent elevating podium and Soundking AV66 audio-visual prompt device make training and reporting more calm and professional.
Additionally, there is a comprehensive stage lighting system, including Soundking DS220 Professional Profile Spotlight, Soundking DS200W Panel Softlight, Soundking D008 Signal Amplifier, Soundking D12-4KW Bypass Box, Soundking Z512 Control Console, and other devices. This system creates a solemn and focused visual atmosphere for the lecture hall, making every important event more impactful and ceremonial.
The successful delivery of the Top Group project marks another benchmark practice for Soundking in the intelligent scenario of high-end manufacturing enterprises. In the future, Soundking will continue to be driven by innovation and based on professionalism, bringing more customers beyond their expectations in terms of intelligent audio-visual experience.
