IV. Design Solution
The integrated solution unifies regular meetings and remote video conferences with the following core advantages:
1. The PA system delivers outstanding speech intelligibility and stable sound pressure complying with Class 1 national standard for combined speech & music reinforcement.
2. Uniform sound coverage and smooth frequency response across service area; speaker appearance and installation do not damage interior decoration style.
3. Free of echo, flutter echo and sound focusing; thick fabric curtains are recommended as supplementary acoustic improvement if insufficient room absorption during decoration.
4. Multi-level circuit protection ensures long-term stable operation and effective equipment protection against unexpected faults.
5. Constant-impedance one-to-one matching between speakers and amplifiers; full-range loudspeakers realize premium sound restoration with easy operation and flexible function.
6. Daisy-chain digital conference microphones feature neat layout, easy installation and minimal wiring without destroying interior decoration, with effective pickup range of 50~80cm.
7. Conference host supports multiple working modes: FIFO, normal, restricted, free, request and voice-activated for flexible conference management.
8. Central control programming enables PTZ rotation, zoom and focus of cameras with auto-tracking to capture close-up for active speakers.
9. Input sources include camera, DVD and laptop signals; outputs feed projector and display devices, all routed via HD hybrid matrix.
10. The hybrid HD matrix supports optional boards for VIDEO, S-Video, VGA, YPbPr, DVI, HDMI, SDI, Fiber and HDBaseT transmission.
11. Support bidirectional IR & RS232 control over extender; controllable via front panel keys, RS232 and LAN.
12. Central control manages matrix switching, camera control, projector & screen lifting, power distribution, volume adjustment, DVD playback, electric curtain and air conditioner to simplify full-system operation.
13. Built-in Ethernet port enables remote network access and cascading; iPad/iPhone control via Wi-Fi connection.
