YH-8028B Dual-Pole Conference Delegate Unit

YH-8028B Dual-Pole Conference Delegate Unit

Stable Connectivity and Flexible Adaptability: 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, delivering strong anti-interference capabilities and easy installation to ensure high system reliability and multi-scenario adaptability.

Superior Audio Performance: Equipped with a high-performance CPU + digital DSP processing circuit, paired with professional cardioid/supercardioid condenser microphone capsules. Delivers sensitive pickup, clear speech, and wide frequency response. Features dedicated circuitry to prevent interference from mobile phones and other electronic devices, effectively avoiding feedback and distortion.

Practical and Durable Design: A 2.4-inch color display provides intuitive system status and timing information. Microphone activation triggers automatic LED illumination for intuitive operation and accidental touch prevention. The microphone boom detaches from the base via a secure screw connection (facilitating replacement, eliminating noise, and ensuring transport safety). The all-metal base and high-quality moisture/dust-resistant buttons combine ergonomic comfort with rugged durability.
