Introduction

DJI™ Mic is a dual channel wireless microphone system, including two transmitters and one receiver, which is able to record two sound sources simultaneously at a distance of up to 250 m*. The transmitter has a built-in omnidirectional microphone, supports the use of an external microphone, and can be clipped to clothing or any place close to a sound source. With the internal 8 GB storage, DJI Mic is able to record audio for up to 14 hours**.
The receiver boasts an OLED touchscreen, on which users can view the real-time volume, wireless signal strength, gain, recording modes, and more. By utilizing the expansion port, the receiver can be connected to a camera or mobile phone to provide high quality audio. The receiver can also be connected to a computer to use as a microphone and with the monitor port the audio can be monitored in real time. The charging case provided is able to charge the transmitters and receiver simultaneously and link them automatically.

• Tested in an obstruction-free outdoor environment.
  ** Tested with a 48,000Hz sampling rate and 24-bit mono WAV audio format.
  DJI Mic has different combos, which include additional items. The features described in this manual are general and apply to all combos.
