This product is a dual-backup system chairperson/delegate microphone, designed for high-end conference applications, combining the stability of wired connections with the flexibility of wireless operation. Key Features Dual-Backup System Architecture Adopts digital-analog dual-backup design with one phantom-powered audio channel and one conference system audio channel. The two microphone links are completely independent with seamless switching capability. Even if one link fails, the other continues to operate normally, ensuring uninterrupted meetings. Large HD Touch Color Display Equipped with a 2.8-inch TFT HD color display with touch key operation, eliminating the noise issues associated with traditional mechanical buttons. The display shows real-time meeting status, speech duration, and system configuration. Imported High-Fidelity Pickup Capsule Features an imported high-fidelity 14mm pure gold diaphragm condenser capsule with super-directional pickup technology, achieving an effective pickup distance of up to 80cm. Delivers high sound reproduction accuracy with clear, natural voice quality. Three Interchangeable Microphone Stem Options Available in three specifications: Array Square Stem (200×28×30mm), Gooseneck Stem (400mm), and Round-Barrel Stem (220×30×30mm). All utilize 5-pin audio processing with dual shielding — offering superior interference resistance compared to 3-pin and 4-pin designs. The patented diamond-angle stem design combines aesthetics with user convenience. Smart Status Indicator The microphone stem features a dual-color indicator: green flashing during self-diagnostics, red during speech — providing clear visual status feedback. Chairperson Priority Control The chairperson unit includes priority functionality to activate the microphone or silence active delegate units with a single touch, enabling effective meeting order management. Built-in Speaker & Headphone Output Features a built-in high-fidelity speaker with intelligent feedback suppression — the built-in speaker automatically mutes when the microphone is activated to prevent acoustic feedback. Includes a 3.5mm stereo headphone jack for external headphone connection with independent volume adjustment. Timed Speech Mode Allows setting speech duration based on meeting requirements, with automatic unit shutdown upon countdown completion — effectively controlling meeting pace. Independent Volume Control Equipped with a dedicated knob for independent volume adjustment — intuitive and convenient operation. Power-On Self-Test Features startup diagnostics — blue indicator flashes during self-test, turning red upon completion, ensuring device readiness. Ring Daisy-Chain Connection Utilizes 6-core T-type cabling with full aluminum foil and water-line shielding, effectively reducing electromagnetic interference for stable signal transmission. Wireless Mode When untethered from the host, the microphone operates in wireless mode: Carrier Frequency: UHF 640MHz–690MHz RF Power Output: 15mW Battery: 3 x AA alkaline or OEM NiMH batteries Current Consumption: <150mA Continuous Operation: Approx. 8 hours Signal Coverage: Indoor radius 60m Recommended Speaking Distance: 20cm–60cm
