I. Industry Background
Benefiting from China’s growing comprehensive national strength and rapid advancement of modern information technology, enterprises and institutions continuously upgrade office informatization standards. Traditional meeting rooms have evolved from simple listening spaces into multi-functional comprehensive hubs for information exchange. Widely equipped with projectors, video recording devices and professional audio equipment, contemporary conference facilities develop into standardized multimedia conference systems with richer functions and optimized design specifications.

II. Requirement Analysis
Following the design principle of demand-oriented, forward-looking, feasible and sustainable development, the integrated system supports daily meetings, video conferences and multi-purpose events with advanced design, stable performance, complete functions and efficient centralized control.
1. Realize convenient unified management over all audio and video subsystems;
2. Adopt DLP high-lumen engineering projector or LCD display for high contrast, sharp image, uniform picture, vivid color, long service life and stable display performance;
3. User-friendly flexible PA system adaptable to diversified conference scenarios;
4. Deploy centralized control platform for full-system quick operation;
5. Meet demands for regular conferences, remote video conferences and multi-functional activities;
6. Support HD signal transmission, terminal signal access and high-definition display output;
7. Satisfy requirements of conference discussion and speech pickup.
III. Design Standards

V. Project Implementation Effect
1. Adequate sound pressure level
With upgraded recording technology and improved public listening standard, the PA system reserves sufficient dynamic headroom for distortion-free reproduction of wide-dynamic-range audio signals. Selected high-power high-sensitivity loudspeakers are matched with amplifiers featuring adequate power margin, enabling the finished venue to fully meet Class 1 national standard for auditorium acoustic specification.
2. Excellent sound field uniformity
Speakers are arranged into point-source arrays according to audience layout to reduce comb filtering effect. Constant-directivity loudspeakers enhance speech intelligibility and ensure full audience coverage, verified via acoustic simulation calculation for even sound distribution.
3. Smooth frequency response characteristic
Each speaker channel is calibrated via parametric equalizer to stabilize beam width across full frequency without peak or dip; digital room equalizer optimizes acoustic coupling between hall and screen area to guarantee flat overall system frequency response.
4. Satisfactory acoustic feedback gain
Optimized speaker layout covers entire audience zone with constant-directivity horns featuring rapid sound attenuation beyond -6dB coverage angle, reliably reaching preset transmission gain target.
5. Strong compatibility & expandability
Beyond conference speech reinforcement, the system supports high-fidelity music playback with effective frequency response ranging from 35Hz to 18kHz; all equipment reserves spare interfaces for future function expansion.
