C-Yark C-869D Professional PA Power Amplifier

C-Yark C-869D is a professional-grade Desktop Delegate Microphone (discussion microphone) from the reliable C-Yark conference series, delivering exceptional audio clarity, robust anti-interference performance, and user-friendly controls for modern conference, boardroom, and multi-participant meeting environments. Designed as a high-quality delegate microphone station, the C-869D complements systems like the C-859C chairman unit, offering seamless integration in daisy-chained wired setups for clear, focused discussions in corporate meetings, government chambers, training facilities, and international summits.

• Intuitive Status Display — Built-in color screen (similar to 2.4-inch models in the series) clearly indicates speaking, mute, or request-to-speak status for instant visual feedback
• Prominent Working Indicator — Bright red LED ring illuminates when the microphone is active, ensuring participants and operators know exactly when a unit is live
• Safe Passive Power Supply — Powered entirely by the central host unit (DC 24V) — no local power adapters needed, maintaining low-voltage safety compliance
• Interference-Resistant Cabling — Connects via shielded 8-core T-type cable (full aluminum foil + water-resistant shielding) to minimize electromagnetic interference from strong sources; optional RJ45 interface supports Cat6/Cat7 cables for hybrid digital-analog backup configurations (analog 48V variants available)
• Focused Audio Pickup — High-performance supercardioid (cardioid electret condenser) microphone capsule captures natural, intelligible speech while effectively rejecting background noise and off-axis sounds
• Advanced Anti-Jamming Technology — Dedicated circuitry blocks disruptions from mobile phones, wireless devices, and nearby electronics for uninterrupted meetings
• Flexible Delegate Operation — Supports multiple delegate units with easy daisy-chain connectivity; works alongside chairman units for priority queuing and orderly discussion management
• Effortless Setup & Maintenance — Simple "daisy-chain" cabling reduces installation complexity and allows quick reconfiguration or troubleshooting in any room layout
