YH-8018A Chairperson Unit
Stable Connectivity and Flexible Deployment: Features a dual-system backup design combining traditional daisy-chain and digital network ring topologies. Supports dual-connection methods via Category 6 RJ45 cables or 8-core dedicated conference cables, ensuring strong anti-interference capabilities and easy installation for high system reliability. Multiple chairman units can be flexibly deployed to accommodate varying meeting room sizes and layouts.
Audio Performance and Efficient Control: Equipped with a high-performance CPU and digital DSP processing circuitry. Microphone boom employs acoustic interference principles for super-directional pickup, delivering clear speech, sensitive audio capture, and feedback suppression. Features dedicated circuitry to mitigate interference from mobile phones and other electronic devices, minimizing distortion. Chairman units support priority control functionality, enabling instant shutdown of all delegate units to manage meeting proceedings.
User Experience and Durable Design: A 2.4-inch color display intuitively shows system status, timing, ID, and other critical information. Microphone activation triggers automatic LED illumination for simple operation and accidental touch prevention. The full-metal base follows ergonomic principles, while buttons feature high-quality moisture-proof and dust-proof design, balancing practicality and durability with an elegant and refined appearance.
Key Features:
1. Dual-system dual-backup connectivity integrates traditional daisy-chain conference systems with digital network ring conference systems. Both links operate independently, ensuring high stability, reliability, and multi-mode convenience.
2. Conference units support either Category 6 Ethernet cables with RJ45 connectors or 8-core dedicated conference cables, adaptable to user environments. This design effectively resists interference, simplifies installation, and ensures reliable transmission.
3. High-performance CPU and digital DSP circuit processing minimize distortion, delivering clearer speech and wider frequency response.
4. 2.4-inch color display shows system status, real-time clock, speaking timer, ID, and microphone status.
5. Chairman unit priority key can mute all delegate units at any time.
6. Supports multiple chairman units with priority functionality, deployable anywhere to control meeting proceedings;
7. Microphone boom employs acoustic interference principles for exceptional super-directional performance: high sensitivity, clear voice capture, wide bandwidth, and reduced feedback susceptibility;
8. Anti-interference circuitry prevents disruption from mobile phones and other electronic devices;
9. Automatic indicator illumination upon unit activation prevents accidental operation, ensuring intuitive and straightforward control;
10. All unit buttons utilize high-quality, long-life switches resistant to moisture and dust;
11. The all-metal base features an elegant, tabletop-style structure designed for ergonomics and contemporary aesthetics.
