^{DJI Mic 3 uses single-pole magnetization and can attract iron blocks weighing up to 1.0 kg.}

All magnetic products contain magnets. It is recommended to keep the DJI Mic 3 Magnetic Clip/Magnet away from bank cards, pacemakers, RAM chips, and hard discs.

1. DO NOT use when wearing heavy clothes (sweaters, down jackets, etc.). The transmitters could fall off due to lack of magnetism.
2. Use with caution during vigorous exercise, for example, jumping, sprinting, etc.

The DJI Mic 3 Transmitter can be mounted on collars, lapels, hat brims, and more using the magnetic clip. The magnetic clip allows for attachment in four directions (up, down, left, or right) for optimal audio capture. The transmitter can also be attached to other parts of your clothing using the magnet, such as the middle of soft clothing, to prevent it from sagging. Additionally, the transmitter has a built-in magnet, so it can be attached to metal objects as needed for recording.

Omnidirectional.

1. Transmitters connect to a receiver via 2.4GHz/5GHz frequency band.
2. Direct Bluetooth connection to smartphone.
3. Direct connection to certain DJI products via DJI OsmoAudio™.

^{Operating frequency allowed varies among countries and regions. Refer to local laws and regulations for more information.}

1. It depends on the compatibility of the livestreaming app and the mobile phone operating system. You can test it with Bluetooth earphones or headsets. If you cannot record audio with the earphones or headset for livestreaming, the transmitter does not support this function when connecting to a mobile phone via Bluetooth. Some phone models may not support stereo-mode livestreaming; please verify through actual use. For software compatibility information, refer to the Third-Party App Compatibility List on the Downloads page of the official DJI Mic 3 webpage.
2. To connect, power on the transmitter. Press and hold the Linking Button for two seconds and the mobile phone will automatically search for available Bluetooth devices. Select DJI Mic 3 TX when it appears and tap to complete linking. When the transmitter's status indicator turns solid blue, the linking is completed. If the mobile phone's Bluetooth cannot find DJI Mic 3, reboot Bluetooth on the mobile phone and link again.
3. When the transmitter is connected directly to your phone via Bluetooth, it supports voice tone presets, gain control, noise cancellation, mute, low cut, 32-bit float internal recording, dual-file internal recording, and adaptive gain control. These features must be enabled through the DJI Mimo app or the receiver. Noise cancellation and internal recording can be turned on or off using the transmitter's power button.

Each DJI Mic 3 Transmitter can connect to up to eight DJI Mic 3 receivers, while each DJI Mic 3 Receiver can connect to up to four transmitters.
DJI Mic 3 supports DJI OsmoAudio™connection ecosystem. The DJI Mic 3 transmitters can directly connect to certain DJI products, namely one transmitter for Osmo Action 4, and up to two transmitters for Osmo 360, Osmo Pocket 3, and Osmo Action 5 Pro. For devices that support connection with two transmitters, you can match any two products from Mic 2, Mic Mini, and Mic 3 for simultaneous use.
The DJI Mic 3 transmitters can directly connect to your smartphone via Bluetooth, but a phone only connects to one transmitter at a time.

DJI Mic 3 supports Adaptive Gain Control, which can be set through the receiver, DJI Mimo app, or DJI OsmoAudio™devices. This feature is off by default. Once enabled, you can choose between Automatic and Dynamic modes.
Automatic Mode (Clipping Prevention): Ideal for environments with dramatic volume fluctuations. It smoothly handles volume fluctuations and suppresses sudden spikes, ensuring balanced and consistent audio output. For example, during interviews at a sports event, you might encounter sudden sounds like engine noise or a starting pistol.
Dynamic Mode (Volume Balancing): 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.

^{Once Adaptive Gain Control is enabled, gain adjustment on the receiver is not supported.
When the DJI transmitters are directly connected to certain DJI OsmoAudio™devices, the above two modes will not be active, only the built-in clipping prevention function of specific devices will take effect. For details, refer to the OsmoAudio™Compability List on the Downloads page of the official DJI Mic 3 webpage.}

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

During internal recording, a file is saved every 30 minutes. The 24-bit and 32-bit float recordings are both saved in WAV format.
You can export recorded files in two ways:
Wired Connection: Connect the transmitter to a computer using the DJI Mic 3 Transmitter Magnetic Charging Cable, or place the transmitter in the charging case and connect it to a computer with the included data cable.
App Download: Connect the transmitter to the DJI Mimo app and use the File Download feature to export recorded audio files.

The DJI Mic 3 Transmitter's internal recording supports simultaneous recording of both original and edited files, which can be selected in Transmitter Settings＞File Format.
The Original File is the raw audio captured by the transmitter, with filenames ending in "orig". The Edited File is the audio that has been enhanced using algorithms such as voice tone presets, low cut, noise cancellation, and adaptive gain control, with filenames ending in "edit".

Take the recording folder "TX_MIC001_20250530_115001" as an example:
TX: Indicates that this folder is for internal recordings of the transmitter.
MIC001: Indicates this is the first internal recording folder for the transmitter. A new folder is created every 50 files.
20250530_115001: Shows the date and time when the folder was created.

Take the recording file "TX01_MIC002_20250527_202904_orig.wav" as an example:
TX01: Indicates the serial number of the current transmitter, which is assigned by the receiver based on the pairing order. This serial number will change if the transmitter is re-paired.
After pairing, the transmitter serial number in the internal recording files will follow the most recent pairing order, regardless of whether the transmitter is currently connected to the receiver.
If the transmitter is removed from the receiver while connected, its serial number in the internal recording files will be reset to TX00.
If you purchase a single transmitter, the transmitter serial number in the internal recording files will be TX00.
When the transmitter is connected to a smartphone or OsmoAudio™ device, the transmitter serial number in the internal recording files will always be TX00.
MIC002: Indicates this is the second recording file from the current transmitter. New recordings are numbered sequentially.
When connected to a receiver or OsmoAudio™device, the date and time are synchronized with the connected device. When using the transmitter alone, you can sync the date and time with your phone via the DJI Mimo app.
orig: Means the audio is the original, unprocessed recording from the transmitter. If it says "edit," it means the audio has been processed by an algorithm.

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.

It can link with up to four DJI Mic 3 transmitters at once.

No.

To monitor audio, first link the DJI Mic 3 Receiver with the transmitters, then plug the 3.5mm earphone jack into the 3.5mm Monitor Port of the DJI Mic Receiver. To adjust the monitoring volume, swipe down on the main screen of the DJI Mic 3 Receiver and go to Receiver Settings > Volume＞Monitor Select to select which transmitter's audio to monitor, and adjust the monitoring volume as needed at Monitor Volume.

Yes. You can lock the receiver screen by pressing and holding the dial for two seconds. The screen will prompt Screen Locked. To unlock, press and hold the dial again. You can also lock the Timecode interface.

You can playback audio on the mobile phone without removing the receiver.

Yes. When the DJI Mic 3 Receiver is connected to your phone via mobile phone adapter, you can use a charging cable to charge both the mobile phone and the receiver through the receiver's USB-C port.

The DJI Mic 3 Receiver's Output Port outputs analog signals for camera connections.
The DJI Mic 3 Receiver's USB-C Port, Mobile Phone Adapter (USB-C or Lightning), and hot shoe output digital signals.

When the DJI Mic 3 Receiver is connected to a camera via 3.5mm TRS cable or hot shoe, you can enable this function and the receiver automatically powers on and off in sync with the camera.

In Receiver Settings, you can set the channel mode to Q (Quadraphonic). In this mode, the audio from the four transmitters is transmitted independently through four channels without being merged. To use the Quadraphonic mode, connect the DJI Mic 3 Receiver to a Sony camera's MI hot shoe using the DJI Mic Series Camera Adapter, or connect it to a computer via USB.
Please note that in Quadraphonic mode, the audio output from the 3.5mm Output Port remains stereo: TX1 and TX3 are combined as the left channel, while TX2 and TX4 are combined as the right channel.

^{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.}

With Lossless Audio enabled, the transmitter delivers uncompressed 48kHz 24-bit audio directly to the receiver, preserving better sound quality.
Ideal for recording scenarios that require high audio quality, such as high-fidelity vocal recording and musical instrument performances.
Because Lossless Audio uses a higher bitrate, it may reduce the effective transmission range. For best results, we recommend using it in environments with minimal wireless interference and when the transmitter and receiver are close to each other.

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 anti-interference performance. However, due to the laws and regulations in some countries or regions, certain 5 GHz frequency bands can only be used indoors. Please select the appropriate mode based on your local laws and regulations, as well as your actual indoor or outdoor environment. In countries or regions where there are no restrictions on the use of 5 GHz bands, you may use the Indoors mode by default, provided it complies with local laws and regulations.

DJI Mic 3 supports group linking, which allows multiple transmitters and receivers to work together. In a multi-receiver network, the receiver that creates the group is designated as the host receiver (displayed as Host on the screen), while receivers that join the group are designated as secondary receivers (displayed as Sec on the screen). Only the host receiver can pair with and control the transmitters. Secondary receivers do not have this capability. Please ensure that all transmitters are disconnected before joining the group.

Please refer to the following steps:
1. To Achieve the 4TX + 1RX Setup With the Charging Case: Place the receiver and two transmitters into the charging case. Wait until the receiver's screen displays the status of the two transmitters, then remove them from the case. Next, place the other two transmitters into the charging case with the receiver. Once the receiver's screen shows the status of these two transmitters, remove both transmitters and the receiver from the case.
To Manually Link 4 TX + 1 RX: Power on both the transmitters and the receiver. On the receiver's main screen, swipe down to enter the settings. Select Device Linking and then add TX. Tap the unconnected transmitter slot to start the linking process. Press and hold the Linking Button on the transmitter until its System Status LED blinks green and blue alternately. Repeat this process for each of the four transmitters.
2. To Link Eight Receivers: Use the receiver that has already been linked with the transmitters as the host receiver. On its main screen, swipe down to enter the settings, select Device Linking and then add RX. For the other receivers, which will act as secondary receivers, swipe down on the main screen to access the settings and select Device Linking to join a group. When the authentication code appears on the touchscreen, tap Confirm to authorize the secondary receivers to join the group. Add seven secondary receivers in sequence to achieve the 4TX + 8RX setup.

^{Before joining a group with a secondary receiver, ensure that it has disconnected from all transmitters.}

When the transmitters or receiver are placed in the charging case, they will automatically shut down, but the linking information will be retained.

When the receiver connects to two or more transmitters, you can adjust them together as a group. To access this feature, swipe up on the main screen of the host receiver, or select the status bar using the dial, and then double-click the dial to enter the group control page. On the group control page, you can adjust the transmitters' internal recording and noise cancellation settings.
On the receiver's main screen, select a transmitter by tapping on the touchscreen or using the dial, and then double-click the dial to enter the individual control page for that transmitter. There, you can mute or unmute the transmitter, and adjust its internal recording, noise cancellation, and voice tone settings.

The battery life of the transmitter and receiver varies depending on the connection method and features that have a major impact on battery life. Refer to the table below for details.

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.

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.

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.

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.

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.

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.

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.

The timecode drift of DJI Mic 3 is 0.5 ppm, which means a maximum deviation of 1 frame over 24 hours*.
DJI Mic 3 supports the following timecode frame rates: 23.98F, 24F, 25F, 29.97F, 29.97DF, 30F, 50F, and 60F.

^{* Measured using DJI Mic 3 (2 TX + 1 RX + Charging Case) in an environment free of electromagnetic interference, with continuous power supplied to the transmitters and receiver following timecode synchronization and throughout 24 hours of continuous recording.}

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.

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.

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.

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.

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.
