FS-330 Digital Wireless Transmitter
Three-in-One Multifunctional + Dual-Mode Stable Transmission: Integrates microphone, laser pointer, and wireless PPT page turning into one device. Combines IR infrared and UHF dual modes, supporting automatic frequency pairing and wireless transmission. Utilizes the UHF band with a 24K sampling rate, paired with dedicated RF technology and digital encoding for minimal noise, no crosstalk, stable transmission over long distances, and crystal-clear, pure voice quality.
Smart Convenience + Customizable: Automatically detects environment, searches for clear channels, and pairs upon startup; seven-level adjustable pairing power for strong anti-interference; OLED color display clearly shows system parameters with customizable brand logo support; adjustable microphone volume with memory function; one-touch mute for hassle-free operation. Professional Sound Quality + Flexible Adaptability: Five-band EQ for tailored vocal effects, with built-in limiter to suppress feedback. Integrated audio sensor supports 3.5mm external headset/lapel mics for versatile scenarios.
Comfortable Battery Life + Energy Efficiency: Ergonomic pen-style microphone body with zoned button layout ensures comfortable grip and lightweight feel. Type-C charging paired with a 3.7V polymer lithium battery delivers ≥12 hours of battery life. Auto-shuts down after 60 minutes without signal input for safety and energy conservation.
Key Features:
1. Integrated design combining microphone, laser pointer, and wireless PPT page-turning functions. Supports IR infrared, UHF auto-pairing, and UHF wireless transmission with dual-mode seamless integration for crystal-clear audio.
2. Operates in the UHF band with a 24K sampling rate, meeting high-quality vocal transmission requirements. Dedicated RF technology and digital encoding ensure low noise, no crosstalk, stable communication, and extended transmission range;
