This is a wireless microphone system with small size and full functions. The transmitter has a built-in electret microphone, which can be directly clipped to the collar for use, or it can be connected to a lavalier microphone via an external input interface, when it is used as a small bodypack transmitter.
This product uses the ISM global unrestricted 2.4G frequency band for transmission. The receiver and transmitter are automatically paired successfully within 2 seconds after turning on, and the effective use distance reaches 50 meters (open and wide occasions). Both the receiver and the transmitter use clear and bright LED lights to display the current input and output audio dynamic messages, the output volume is adjustable, and the 3.55mm TRS output is used to connect to digital/SLR cameras, camcorders, recorders, tablets, mobile phones and other devices Assist in picking up high-fidelity audio.
It is suitable for applications such as interviews, micro video recording or commercial presentations.
