Centralized Conference System Solution

Centralized Conference System Solution
(A high-fidelity, intelligent AV integration platform for modern meeting environments)

I. Project Background & Objectives

Challenges
Traditional systems fail to address:

• Natural voice reproduction

• Multi-scenario adaptability

• Acoustic precision in complex spaces

Design Goals

1. True-to-Life Audio

• Achieve co-localized sound fields (source ↔ speaker) with <1% harmonic distortion

2. Acoustic Excellence

• Uniform SPL (≤±3dB variance), STI ≥0.6, RT60 adaptive control (0.8–1.5s)

3. Multi-Mode Flexibility

• Seamless switching between conference/remote/emergency modes

II. Core System Architecture

1. High-Fidelity Sound Reinforcement

• Hybrid Speaker Array

• Line arrays (main) + point-source fills (peripheral)

• EASE simulation-optimized placement

• Phase-Coherent Components

• Full-range speakers (50Hz–20kHz ±2dB) + linear-phase DSP processing

2. Intelligent Control Hub

• Unified Management

• Crestron/AMX-based central control (customizable GUI)

• One-touch presets: "Boardroom"/"Theater"/"Voting" modes

• AI Environment Sync

• Auto-adjusts HVAC/lighting/curtains based on voice activity

3. Reliability Engineering

III. Deployment Strategy

Key Equipment

Acoustic Optimization

• Primary Zones

• 15° downward tilt, 2.2m height (ear-level alignment)

• Bass Management

• Dual 18" subwoofers with RMC (Room Mode Correction)

IV. Validation & Compliance

Testing Protocols

1. Objective Metrics

• Norsonic Nor140: Verify SPL uniformity (≤±3dB @1kHz)

• SMAART v9: Phase coherence analysis (±5° tolerance)

2. Subjective Evaluation

• ITU-R BS.1116 blind testing by focus group

Standards Met

• GB/T 50314-2015 (Intelligent Building Design)

• ANSI/ASA S12.60 (Classroom Acoustics)

V. Lifecycle Support

• Preventive Maintenance

• Quarterly transducer inspection + FIR filter recalibration

• Emergency Service

• <4hr onsite response for critical failures

Typical Applications

• Legislative chambers

• Corporate war rooms

• Distance learning auditoriums

(System achieves 40% energy savings vs. conventional setups while delivering 20dB lower noise floor.)

Output Deliverables:

• Acoustic simulation reports (EASE/GLL files)

• Control system programming profiles

• As-built measurement certificates
