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.

Why do I hear a regular buzzing sound in my footage after enabling timecode?

When ATC (Audio Timecode) output is enabled, the timecode information is recorded onto the left audio channel of your video. As a result, you may hear a regular buzzing sound when playing back the footage. Software like DaVinci Resolve can read timecode from the audio track to synchronize your clips automatically.

How is the timecode synchronized between the host receiver, secondary receivers, and transmitters?

Once the transmitters and receivers are connected to form a group, the host receiver automatically synchronizes timecode information with the transmitters and secondary receivers at regular intervals, without the need for manual user operation.

Does the transmitter support timecode input?

The transmitter automatically receives timecode from the receiver. It does not support synchronizing timecode from devices other than the receiver, nor does it support outputting timecode to other devices.

How to synchronize external timecode?

Each receiver can output timecode to cameras, recorders, and other equipment. Please select the appropriate adapter cable and output mode according to the device's port. For example, DJI Ronin 4D supports timecode input. You can connect the receiver to Ronin 4D's timecode port using a 3.5mm TRS to SDI adapter cable, set the receiver's timecode output type to L-OUT, and ensure that the device frame rates are matched to output timecode to Ronin 4D.
Only the host receiver supports external timecode input. After synchronization, the host receiver will automatically distribute the external timecode to the secondary receivers and transmitters. To synchronize external timecode, connect the host receiver's Output Port to the external timecode generator, switch to L-IN, and tap Sync. This will synchronize the external timecode to the receivers and transmitters. After synchronization, you can choose to disconnect from the external timecode generator or keep the connection. If you disconnect, DJI Mic 3 will continue to run its internal timecode independently. If you keep the connection, the host receiver will continuously receive external timecode and synchronize it with all receivers and transmitters in the network.
When disconnecting from the external timecode generator, please ensure that the disconnection icon appears on the receiver's screen to avoid synchronization errors when reconnecting the timecode generator.

How do I synchronize timecode to Osmo Pocket 3 or Osmo Action 5 Pro?

To synchronize timecode, enable the timecode function on DJI Mic 3 and set the receiver's timecode output type to L-OUT. Make sure all devices are set to the same frame rate. On Osmo Pocket 3 or Osmo Action 5 Pro, go to settings and scroll down to find the Timecode option. Then, connect the receiver to Osmo Pocket 3 or Osmo Action 5 Pro using the USB-C mobile phone adapter. The timecode will be synchronized automatically.

Will enabling timecode affect audio output?

DJI Mic 3 offers four timecode modes:
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.
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.
The impact of timecode on audio output varies depending on the selected timecode mode and channel mode. For details, please refer to the table below.

DJI Mic 3 Accessories

What functions can be achieved when using DJI Mic 3 with the DJI Mic Series Camera Adapter?

The DJI Mic Series Camera Adapter lets you connect the DJI Mic 3 Receiver directly to a Sony camera's MI hot shoe, allowing for audio recording without the Camera Audio Cable (3.5mm TRS). It supports 48kHz 24-bit digital audio recording. Your Sony camera can also supply power to the DJI Mic 3 Receiver through the adapter.
After enabling the Auto On/Off With Camera in the receiver or DJI Mimo app, the receiver, when connected to the camera via the hot shoe, will automatically turn on when the camera is turned on and turn off when the camera is turned off.
Additionally, this adapter can solve the issue of electrical noise that may occur when certain Sony cameras (such as the A7S3, FX3, A6700, etc.) are connected to specific microphones using a 3.5mm cable.

What cameras are compatible with the DJI Mic Series Camera Adapter?

The DJI Mic Series Camera Adapter is only suitable for Sony cameras with an MI hot shoe. For a complete list of compatible devices, refer to the DJI Mic Series Camera Adapter Compatibility List available on the Downloads page of the official DJI Mic 3 webpage.

Can the DJI Mic Series Camera Adapter be used with DJI Mic, DJI Mic 2, or DJI Mic Mini?

The DJI Mic Series Camera Adapter is compatible with DJI Mic 3 and DJI Mic Mini, but not with DJI Mic and DJI Mic 2.

What is the difference between using the DJI Mic Series Camera Adapter and using the Camera Audio Cable (3.5mm TRS)?

The DJI Mic Series Camera Adapter enables digital audio recording and allows the camera to power the receiver, while the Camera Audio Cable (3.5mm TRS) supports analog audio recording. With either connection method, the receiver supports Auto On/Off With Camera.

What should I do if my camera shows an incompatibility message when using the DJI Mic Series Camera Adapter?

If your camera does not support digital audio signals, it will not recognize the DJI Mic Series Camera Adapter. For detailed compatibility information on Quadraphonic mode, refer to the Quadraphonic Computer Software Compatibility List available on the Downloads page of the official DJI Mic 3 website.
