SR-350 Digital Wireless Microphone

SR-350 Digital Wireless Microphone

Combining three core functions—microphone, laser pointer, and wireless PPT page turning—this innovative device features a dual-mode design supporting both IR infrared and UHF wireless transmission. It supports automatic frequency pairing and 24K high-sampling-rate transmission. Paired with dedicated RF technology and digital encoding, it delivers high-quality vocal performance with minimal noise, no crosstalk, stable transmission, and clear reception over long distances.

Automatically detects the environment and selects the optimal operating channel upon startup. Features seven levels of adjustable pairing power for strong anti-interference capability. Built-in microphone sensor + 3.5mm external mic jack supports headset/lapel mic expansion and audio file transfer. Features five-band EQ tone adjustment, adjustable volume (with memory function), one-touch mute, and limiter anti-feedback design to adapt to diverse vocal scenarios.

Pen-shaped ergonomic design ensures comfortable grip, while lightweight construction enables effortless operation. The OLED color display clearly shows system status and parameters, with support for custom brand logos. The Type-C charging port pairs with a 3.7V polymer lithium battery (with protection circuitry), delivering ≥12 hours of battery life. It automatically powers off after 60 minutes without signal for enhanced energy efficiency and environmental sustainability. The receiver features versatile connectivity including a 6.35mm microphone output and miniUSB PPT interface, making it widely applicable for teaching, presentations, conferences, and other scenarios. It enables integrated “audio capture + presentation” for efficient output.
