(1) Audio System
Sound Reinforcement Equipment
A distributed speaker layout is adopted inside the building. According to the functions and acoustic characteristics of different spaces, different types of speakers are selected. For example, in large meeting rooms and multi-function halls, VQ series line arrays are installed, which can provide uniform sound coverage and ensure that participants in every corner can hear clearly. In small meeting rooms and rest areas, professional full-range speakers are used, which not only ensure sound quality but also do not affect the spatial aesthetics.
Audio Processing Equipment
Professional digital audio processors are equipped, which can perform precise equalization, compression, limiting and other processing on the input audio signals to effectively improve sound quality. At the same time, they can independently adjust the volume and timbre of different areas to meet the needs of different scenarios. For example, during large-scale lectures, the clarity and loudness of the sound can be enhanced; while in small business negotiations, a soft and comfortable sound environment can be created.
Sound Pickup Equipment
A variety of sound pickup equipment are configured according to the needs of meeting activities. Capacitor conference microphones are arranged on the conference room tables, which have high sensitivity and clear sound quality, and can accurately pick up the speeches of participants. For large-scale activities and speech scenarios, wireless handheld microphones and lavalier microphones are also equipped to facilitate the free movement of speakers and ensure stable sound transmission.
(2) Video System
Display Equipment
Ultra-high-definition LED large screens are adopted, featuring high brightness, high contrast and wide viewing angle. Whether playing presentations, video materials or conducting live broadcasts, they can present clear and realistic image effects.
Video Signal Processing Equipment
To realize the switching, splicing and processing of multiple signal sources, professional video matrix switchers and image processors are installed. This equipment can integrate video signals from different sources such as computers, cameras and Blu-ray players, and flexibly switch to the corresponding display equipment according to activity needs. At the same time, the image processor can also perform scaling, cropping, splicing and other operations on video signals to achieve creative video display effects, such as multi-screen linkage display in large-scale activities.
Camera Equipment
High-definition cameras are installed in meeting rooms and event venues for meeting recording and event live broadcasting. These cameras have auto-focus, auto-white balance and pan-tilt control functions, and can flexibly capture images from various angles. Cooperating with video signal processing equipment, real-time switching and recording of multiple video signals can be realized, providing high-quality video materials for subsequent data sorting and promotion.

(1) Description of Pipeline and Line Laying
● High-quality wires are used for speaker wires, which are designed and adopted according to length and thread calculation formulas to reduce power loss.
● Speaker plugs are all clip-on at fixed positions.
● Microphone wires are transmitted in a two-core balanced manner to reduce noise.
● Embedded microphone wires are all double-shielded to isolate interference.
● The detailed design of relevant lines and pipelines will be carried out in the in-depth design of the sound system.
Description of Speaker Installation Process
The load-bearing capacity of all ceiling-mounted and wall-mounted speakers is designed and certified by the architectural design department to ensure long-term use. All steel structures and load-bearing components for speaker hoisting adopt finished overall powder spraying technology, plus anti-corrosion and anti-rust treatments such as anti-rust paint and marine topcoat. All fasteners are made of high-quality stainless steel or galvanized products to ensure the safety of reliable use for a long time.
Power Supply and Grounding System
(1) The control room requires the owner to provide an independent secondary power supply to reduce power noise interference.
(2) The power supply of the sound system must adopt an independent grounding system, and the standard shall be implemented in accordance with the relevant national "Code for Installation of Low-Voltage Power Distribution Devices".
5. Application Scenarios
Business Meetings
In daily business meetings, the audio system ensures that the speeches of each participant can be clearly conveyed, and the video system displays relevant data and materials through high-definition displays to improve the efficiency and effect of the meeting. For example, in a project report meeting, the speaker uses a wireless microphone to explain, and at the same time, the PPT in the computer is displayed on the large screen through the video matrix switcher, allowing participants to intuitively understand the project progress and results.
Industry Forums
For large-scale industry forums, the powerful sound reinforcement capability and precise audio processing function of the audio system can meet the listening needs of many participants. Multiple high-definition cameras capture the forum scene from all angles, and real-time switching and live broadcasting are carried out through video signal processing equipment, allowing industry professionals who cannot be present to participate synchronously. At the same time, the forum theme, guest introduction and speech content displayed on the LED large screen create a professional and warm atmosphere.
Investment Promotion Conferences
In investment promotion conferences, the professional audio-visual system becomes a powerful tool to display regional advantages and project highlights. Through carefully produced promotional videos, presented with shocking visual effects on the high-definition large screen, combined with high-quality audio explanations, it attracts the attention of potential investors. For example, video splicing technology is used to combine and display multiple pictures such as regional planning maps and project renderings, bringing a more comprehensive and intuitive feeling to the audience.
