In the control menu, you can link devices, connect the receiver to the DJI Mimo app, and set up timecode.  Tap Receiver Settings or Transmitter Settings to configure more parameters.

Below are descriptions of certain features that may need further explanation.

19 / 71
Section 19

Timecode

Timecode is a time marker used to synchronize audio and video.

Supported timecode modes

Master Run: The main RX timecode is set to Master Run by default, managing the generation and synchronization of timecode within the group and with external devices. Auto Jam: The secondary RX timecode defaults to Auto Jam, periodically syncing by receiving the timecode and frame rate from the main RX and aligning with external devices.

Common video frame rates are supported, with 29.97 fps set as the default. Ensure all recording devices maintain identical frame rates during recording.

20 / 71
Section 20

Timecode output type

  • N/A: The receiver runs the timecode internally but does not output it externally.
  • L-IN: Used to synchronize timecode from an external timecode generator to the receiver.

When the receiver receives timecode from an external device, EXT is displayed in the upper right corner of the screen. Tap SYNC to synchronize the timecode to other devices. Tap RESET to reset the timecode.

  • L-OUT: The receiver outputs timecode externally in Linear Timecode(LTC) format.
  • A-OUT: The receiver outputs timecode externally in Audio Timecode(Audio-TC/ATC) format.

Gain

Tap to open the gain slider and move the slider to adjust the receiver output gain. If the sound is overexposed, turn down the receiver gain first.

26 / 71
Section 26

• Lossless Audio

When lossless audio mode is enabled, the transmitter sends 48 kHz 24-bit uncompressed audio to the receiver, ensuring higher audio quality.

27 / 71
Section 27

• Auto On/Off With Camera

When enabled, the receiver will automatically power on and off  with the camera when connected to the camera via the 3 . 5 m m audio cable or camera adapter.

28 / 71
Section 28

• Auto Off

The receiver will automatically power off when the receiver is not linked to a transmitter within 15 minutes after powering on.

29 / 71
Section 29

Environment

Both modes support automatic frequency hopping between 2.4 GHz and 5 GHz bands. The difference lies in the operating frequency covered by the two modes in different environments.

The Indoors mode covers a wider frequency range and offers stronger antiinterference performance.  However, due to the laws and regulations in some countries or regions, certain 5 GHz frequency bands can only be used indoors.  Select the appropriate mode based on your local laws and regulations, as well as your actual indoor or outdoor environment.

Section 33

• Adaptive Gain Control

Automatic Mode: Ideal for environments with dramatic volume fluctuations. It smoothly handles volume fluctuations and suppresses sudden spikes, ensuring balanced and consistent audio output.

Dynamic Mode: It automatically adjusts the audio output's dynamic range based on changes in input levels, compensating for input that is too low or too high by increasing or decreasing the gain as needed, ideal for quiet indoor settings like studios.

34 / 71
Section 34

• 32-Bit Float Recording

When enabled, the transmitter can independently record audio files in 32-bit float, which offers a wider dynamic range for audio post-editing.
