Monitoring

The monitoring feature allows you to listen to recorded audio in real-time through headphones during the recording process. This enables you to quickly identify and correct issues like low volume, excessive background noise, or audio distortion.

It is essential for professional recording, interviews, or video production, as it ensures the recorded audio quality meets expectations, thereby reducing the time and effort needed for post-production.

DJI Mic 3，DJI Mic 2 and DJI Mic

How to Use

DJI Mic 3

To monitor audio, link the receiver and transmitter, then connect a 3.5 mm headset to the DJI Mic 3 receiver monitor port.

When one transmitter is connected directly to an OsmoAudio camera, connect a USB-C headset to the camera USB-C port to monitor audio. Audio monitoring is not supported in other Bluetooth-based connection scenarios.

To adjust the monitoring volume, swipe down on the home screen of the DJI Mic 3 receiver, tap Receiver Settings, then swipe left and tap Audio Monitoring.

For remote audio monitoring, add a second receiver and connect a 3.5 mm headset to its monitor port.

Note: The monitor port does not support stereo.

DJI Mic 2

Connect the transmitter and receiver, and plug the 3.5mm TRS headphones into the 3.5mm monitor port of the receiver and you can begin monitoring.

You can also adjust monitoring volume: Slide down from the main screen of the receiver to enter Receiver Settings, and slide left to select Volume to adjust the monitoring volume.

DJI Mic

Connect the transmitter and receiver, and plug the 3.5mm TRS headphones into the 3.5mm monitor port of the receiver and you can begin monitoring.

You can also adjust monitoring volume: Slide down from the main screen of the receiver to enter the Settings page, and slide to the left and tap Monitor Volume to adjust the volume.

DJI Mic Mini 2S/DJI Mic Mini and DJI Mic Mini 2

1. The transmitter has no audio output port, so you cannot monitor audio with a headset.

2. The receiver has no 3.5 mm monitor port. To monitor audio, use the headphone port on the connected camera. Audio monitoring must be supported by the camera.

3. The USB-C port on the side of the DJI Mic Series Mobile Receiver supports audio monitoring. To monitor audio, plug in an analog USB-C headset or connect a 3.5mm headset via an adapter. Digital headsets are not supported.

Intelligent Noise Cancelling

The feature reduces background noise, enhances voice clarity, and improves recording quality. It is perfect for situations requiring high-quality audio, such as interviews, video production, and podcast recording.   

Applicable Products

DJI Mic 3、DJI Mic Mini 2S、DJI Mic Mini 2、DJI Mic Mini and DJI Mic 2 

How to Use

DJI Mic 3

1. After turning on the transmitter and receiver, tap the transmitter that requires noise reduction on the receiver screen, then tap the noise reduction icon (you can tap multiple times to adjust the noise reduction level). If the transmitter indicator turns solid yellow, it indicates successful noise reduction activation;

2. Press the transmitter power button twice. When the transmitter LED turns solid yellow, noise cancelling has been enabled successfully.

3. TX can be connected to the smartphone and Mimo app separately, allowing noise reduction to be turned on or off within the app, and supports adjusting the noise reduction level.

4. RX is connected to the mobile phone via an adapter, and the Mimo app can be used to enable or disable TX group noise reduction, adjust the noise reduction level, but does not support enabling or disabling noise reduction for individual TX units.

DJI Mic Mini 2S

1. Double-press the Transmitter Power Button. If the transmitter LED turns solid yellow, indicating that noise reduction is enabled;

2. Connect to the Mimo app to adjust the noise reduction level: Basic Noise Reduction (quiet indoor scenarios) / Strong Noise Reduction (noisy outdoor scenarios).

DJI Mic Mini 2/DJI Mic Mini

1. Short press the transmitter power button; if the transmitter noise reduction indicator (on the side without buttons) lights up solid yellow, it indicates that noise reduction is successfully enabled.

2. When the DJI Mic Mini TX/DJI Mic Mini 2 TX and DJI Mic Mini RX are linked, the DJI Mic Mini RX, when connected to the Mimo app, supports adjusting the noise reduction level. Basic noise reduction is suitable for indoor low-noise environments, while strong noise reduction is suitable for noisy outdoor scenarios.

3. When DJI Mic Mini TX/DJI Mic Mini 2 TX is directly connected to a phone via Bluetooth, you can enable noise reduction by single-pressing the transmitter power button, but only Strong Noise Reduction is supported.

DJI Mic Mini/DJI Mic Mini 2 also support Clipping Control; when the volume is too high, the system will automatically reduce the volume to prevent distortion and thus improve the audio capture success rate.

DJI Mic 2

DJI Mic 2 now features an intelligent noise cancelling function that effectively lowers environmental noise.   

Adaptive Gain

Applicable Products

DJI Mic Mini 2S，DJI Mic 3

How to Use

DJI Mic Mini 2S/DJI Mic 3 supports adaptive gain control, which can be set via the receiver, the DJI Mimo app, or DJI OsmoAudio™ devices. This feature is disabled by default, and once enabled, you can select either Automatic or Dynamic modes.

Automatic Mode (Prevent Audio Clipping): The mode is ideal for environments with large fluctuations in audio volume. It can smoothly manage sudden changes in sound, suppressing unexpected fluctuations to ensure consistent and balanced audio output. For example, it’s useful during sports interviews where sudden noises like engine sounds or a starter pistol may occur.

Dynamic Mode (Ensure Consistent Loudness): It automatically adjusts the audio output’s dynamic range based on changes in input signal levels, increasing or decreasing the gain to compensate for signals that are too low or too high. This mode is suitable for quiet environments, such as recording studios.

Timecode

Applicable Products

DJI Mic 3

How to Use

DJI Mic 3 features a newly added, built-in high-precision timecode function that supports mainstream timecode output modes (L-IN, LTC-OUT, ATC-OUT).

Once Timecode is enabled, the receiver will automatically synchronize the timecode with the transmitters, and the internal recording files on the transmitters will also include timecode information, with a deviation of less than one frame within 24 hours. After multiple transmitters are synchronized using the same timecode source, footage can be aligned effortlessly in post-production software, greatly improving efficiency for multi-camera and multi-track editing.

DJI Mic 3 can receive timecode information from other timecode generators (such as Tentacle Sync, Deity, etc.), and can also function as a standalone timecode generator. It also supports timecode synchronization with OsmoAudio™ camera devices.

Video Footage

To synchronize timecode on a third-party timecode generator with DJI Mic 3, please refer to the following steps:

1. Enable the timecode function on the receiver or in the DJI Mimo app.

2. Set the same frame rate on the receiver to ensure consistency across all recording devices.

3. Select the appropriate output mode based on whether your camera or the recording device supports timecode input:

• If the camera or the recording device supports timecode input:

① Set the output mode to L-OUT.

② Use a USB-C or dedicated cable to connect the receiver’s timecode output to your camera or recording device’s timecode input.

③ OsmoAudio devices, Ronin 4D, Sony FX3 (requires a specific USB cable), and other devices support this connection.

④ For OsmoAudio devices, open the timecode interface on the device before connecting the cable to start syncing.

• If the camera or the recording device does not support timecode input:

① Set the output mode to A-OUT.

② Connect the receiver to your camera with a 3.5mm audio cable.

③ In A-OUT mode, the timecode signal will use one audio channel. You can later align and sync your footage in post-production using the beep sound from that channel.
