FS-100J Digital Pen-Shaped Wireless Microphone

Dual-Frequency Stable Transmission + Professional Audio Quality: Infrared + UHF dual-frequency technology eliminates frequency interference and dropouts. Fully digital transmission + DSP signal processing delivers a wide 30Hz–20kHz frequency response with zero latency. 4-level adjustable digital feedback suppression + 7-band equalizer, paired with anti-pop and wind noise protection. Electret condenser capsule delivers clear, long-range pickup with transparent, natural sound, eliminating plosive sounds.

Smart Convenience + Hassle-Free Management: Built-in gyroscope chip enables standby mode when stationary, wake-up upon pickup, and auto-shutdown after prolonged inactivity for “set it and forget it” operation. Automatically pairs with same-brand receivers upon startup, compatible across classrooms for one microphone per person hygiene. High/low power switching adapts to scenarios with simple, efficient maintenance.

Multi-function integration + customizable: Combines microphone, laser pointer, and wireless PPT control with programmable buttons. OLED HD display clearly shows device status with customizable interface for intuitive operation. 3.5mm external port supports headset/lapel mics for enhanced versatility.

Flexible Charging + Practical Design: Supports direct charging via Type-C or optional docking station. Reversible charging with three-point contact design eliminates orientation concerns. Ergonomic grip ensures comfort during extended teaching sessions, delivering worry-free durability.
