Introduction

DJI Mic 2 is a dual channel wireless microphone system, including two transmitters and one

receiver, which is able to record two sound sources simultaneously. Each transmitter has a built-

in omnidirectional microphone, which can be connected to DJI Osmo Pocket 3, mobile phones

and other devices via Bluetooth, and supports standalone recording and intelligent noise

cancelling. The transmitter is equipped with a clip for ease of portability, and accommodates

external microphones to meet o-camera recording needs while enhancing audio quality.

The receiver boasts an OLED touchscreen, on which users can view the real-time volume levels,

wireless signal strength, gain, recording modes, and more. By utilizing the expansion port, the

receiver can be connected to a camera or mobile device to capture high-quality audio, or can

be used as a microphone when connected to a computer. Additionally, an independent monitor

port on the receiver allows for real-time audio adjustments. The charging case provided is able

to charge the transmitters and receiver simultaneously and link them automatically.
