FAQ

DJI Mic 3

  • What can I use DJI Mic 3 with?
    You can use DJI Mic 3 with a range of devices, including cameras, smartphones (via USB-C/Lightning port or direct Bluetooth connection), and computers.
    DJI Mic 3 supports DJI OsmoAudio™ connection ecosystem. The transmitter supports direct Bluetooth connection to Osmo 360, Osmo Action 5 Pro, Osmo Action 4, or Osmo Pocket 3 without a receiver, delivering premium audio and simplifying your gear and workflow.
    For a complete list of compatible devices, refer to the Mobile Phone & Tablet Compatibility List and OsmoAudio™ Compatibility List available on the Downloads page of the official DJI Mic 3 webpage.

  • What are the differences between different DJI Mic 3 combos? How should I choose?
    DJI Mic 3 (2 TX + 1 RX) includes a charging case, one receiver, and two transmitters, suitable for two-person audio recording, and providing extended battery life.
    DJI Mic 3 (1 TX + 1 RX) includes one receiver and one transmitter, suitable for single-person audio recording of individual creators.
    The DJI Mic 3 Transmitter can be used with mobile phones, Osmo 360, Osmo Action 5 Pro, Osmo Action 4, or Osmo Pocket 3. Additionally, the DJI Mic 3 Transmitter is compatible with other DJI Mic 3 combos, allowing multiple transmitters and receivers to be used together.
    The DJI Mic 3 Receiver is compatible with other DJI Mic 3 combos, allowing multiple transmitters and receivers to be used together. It can also be used independently as a timecode generator.

  • Do I need to activate DJI Mic 3?
    No. DJI Mic 3 is ready to use without activation. You can scan the QR code on the package to register for a one-year warranty extension.

  • How do I update the firmware of the DJI Mic 3 transmitters and receiver?

  1. Connect the DJI Mic 3 Receiver to a phone either via a phone adapter (USB-C or Lightning) or directly to the DJI Mimo app, and update the firmware for the receiver in the DJI Mimo app. After placing the receiver in the charging case, you can also update the firmware for the transmitters and the charging case.
  2. A DJI Mic 3 Transmitter can also connect directly to the DJI Mimo app to complete its firmware update.
    The DJI Mic 3 Mobile Phone Adapter (Lightning) is sold separately.

  • How do I link the DJI Mic 3's transmitters with the receiver?
    The transmitters and receiver in the same combo are already linked by default. If you need to link them again, you can do so in the following ways:

    • Method 1: Put the transmitters and receiver into the charging case and they will link automatically.
    • Method 2: Power on the transmitters and receiver, swipe down on the receiver's main screen to enter the Settings, then swipe left to choose Device Linking. Add TX by selecting the desired TX slot. Press and hold the Linking Button on one transmitter, and follow the on-screen instructions to complete linking. When the System Status LED on the transmitter blinks green and blue alternately, it indicates that linking is in progress. When the LED turns solid green, the linking is complete.
      To end linking during the process, tap Cancel.

  • How many recording modes does DJI Mic 3 provide?
    DJI Mic 3 has three recording modes: M (Mono), S (Stereo), and Q (Quadraphonic).

    1. M (Mono Mode): Under Mono mode, the audio recorded by all transmitters will be combined in one channel.
    2. S (Stereo Mode): Audio from the two transmitters is recorded via separate channels. When there are more than two transmitters, TX1 and TX3 are combined to form the left channel output, while TX2 and TX4 are combined to form the right channel output.
    3. Q (Quadraphonic Mode): Audio from the four transmitters is recorded via separate channels.

  • What functions does the DJI Mic 3 Charging Case provide?
    The DJI Mic 3 Charging Case can be used for linking the transmitters with the receiver, as well as storing the transmitters, receiver, mobile phone adapters (USB-C or Lightning), locking audio adapter cable, windscreen, magnet, and magnetic clip. When fully charged, it can charge two transmitters and one receiver approx. 2.4 times.

  • What is the maximum transmission distance between DJI Mic 3's transmitters and the receiver?
    400 m*
    *Measured using DJI Mic 3 (2 TX + 1 RX + Charging Case), with Lossless Audio off, in an open, unobstructed environment free of interference.

  • How long does it take to fully charge the transmitters and receiver using the DJI Mic 3 Charging Case? How long does it take to fully charge the charging case separately?
    It is recommended to use a 5V/2A charger to charge the DJI Mic 3 transmitters and receiver, and a 5V/3A charger to charge the charging case.
    The DJI Mic 3 transmitters and receiver both support fast charging. When using the DJI Mic 3 Charging Case, both the transmitters and receiver can be charged to 80% in just 18 minutes. The transmitters can also be charged via the DJI Mic 3 Transmitter Magnetic Charging Cable, reaching 80% in 18 minutes.
    At room temperature, it takes approximately 50 minutes to fully charge the transmitters and the receiver using the charging case. It takes about 1.5 hours to fully charge the charging case separately.

  • How do I enable noise cancellation on DJI Mic 3? How to adjust the noise cancellation levels?
    You can enable or disable noise cancellation by double-pressing the Power Button on the DJI Mic 3 Transmitter once.
    When joining a group, users recording with the DJI Mic 3 Receiver can swipe up on the receiver's main screen to access the settings. From there, you can adjust the noise cancellation levels (Strong or Basic) for all connected transmitters, or tap on a transmitter icon to set its noise cancellation level separately.
    When recording with a phone, you can adjust the noise cancellation levels (Strong or Basic) using the DJI Mimo app.
    When an Osmo 360, Osmo Action 5 Pro, Osmo Action 4, or Osmo Pocket 3 is connected directly via OsmoAudio™, settings can be adjusted on the product interface.

  • What is the internal storage of the DJI Mic 3 transmitters? Do the transmitters support external SD cards for storage?
    The DJI Mic 3 transmitters have built-in 32GB storage and do not support external storage. The recording duration under different conditions is as follows:

    • 24-bit (Single File): 57.3 hours
    • 24-bit (Dual File): 28.6 hours
    • 32-bit Float (Single File): 43.0 hours
    • 32-bit Float (Dual File): 21.5 hours

  • How do I delete audio files from a DJI Mic 3 Transmitter?
    The recorded audio can be exported or deleted after connecting the transmitter to a computer. If formatting is needed, it can also be done through the receiver or the DJI Mimo app.
    When the storage space of the DJI Mic 3 transmitters runs out and Loop Recording is enabled, the oldest recording will be automatically overwritten.

Timecode

  • What are LTC and ATC in timecode? How do I use them?
    Timecode is a system for marking time in audio and video content, allowing you to quickly synchronize files and improve production efficiency.
    LTC (Linear Timecode) is commonly used for synchronizing devices that support timecode, such as cameras, recorders, and timecode generators.
    ATC (Audio Timecode) is a method of embedding timecode into an audio track, typically used with cameras that do not natively support timecode.
    To use timecode, check your camera or recorder's user manual to see which timecode formats are supported, and select the appropriate adapter cable if needed. Most popular non-linear editing software can read both LTC and ATC.
