SM-3620D Digital Wireless Video Tracking Touch-Screen Conference System Representative Unit
Equipped with a professional high-fidelity condenser microphone capsule, it offers sensitive pickup and clear voice reproduction, ensuring superior conference audio quality.
Utilizing UHF wireless transmission technology (50m indoor / 90m outdoor effective range) combined with anti-electromagnetic interference circuitry, it eliminates disruptions from mobile phones and other electronic devices, delivering stable and reliable signal transmission.
Features a 2.4-inch high-brightness IPS TFT display for real-time status monitoring, including microphone status, battery level, and speaking volume, providing clear visibility at a glance;
Dual-color indicator ring on the microphone head (red for active speaking / green for request to speak), intuitive touch-sensitive switch (green for standby / red when pressed), and side-mounted mechanical volume control switch for clear operation logic and convenient adjustment;
Includes a built-in speaking timer to meet meeting time management needs.
Features a high-performance built-in lithium battery with a Type-C port supporting simultaneous charging and use. Ultra-low power consumption design enables continuous speaking for ≥8 hours and standby for ≥12 hours, ensuring long-lasting battery life.
The speaking unit supports service requests for tea/water, paper/pen, and assistance, adapting to practical meeting needs and enhancing usability.
