DJI Mic Mini 2 Transmitter

DJI Mic Mini 2 Transmitter Summary

The DJI Mic Mini 2 Transmitter is a standalone wireless microphone for use with DJI Mic Mini 2 and compatible DJI audio systems. It provides a lightweight, wearable microphone for expanding an existing kit or replacing a transmitter.

Weighing approximately 11g without the magnetic clip or magnet, it can be worn discreetly for interviews, vlogging and mobile content creation. It records omnidirectional 48kHz 24-bit audio and supports voice tone presets, noise reduction, automatic limiting and safety track recording when paired with a receiver or compatible device.

The transmitter can connect directly to supported DJI devices via OsmoAudio or to smartphones via Bluetooth, allowing flexible recording without requiring a receiver in some workflows.

Overview and Key Improvements

This second-generation transmitter adds expanded audio control with three selectable voice tone presets and two levels of noise reduction, allowing adjustment across different recording environments[4][5]. Automatic limiting is included to reduce clipping when input levels peak, improving reliability during unpredictable recordings[6].

Direct connection support via DJI OsmoAudio enables use with compatible DJI devices without requiring a receiver, simplifying recording with supported Osmo cameras[7].

DJI Mic Mini 2 Transmitter In More Detail

Magnetic Covers

The transmitter includes interchangeable magnetic front covers in Obsidian Black and Glaze White, with additional multi-colour magnetic covers and windscreens available separately[1]. Time Series covers are also available, featuring illustrated designs representing different stages of creativity.

Transmitter Design

The body measures 28.58×28.04×13.52mm and weighs approximately 11g without the magnetic clip or magnet[9]. It supports both clip-on and magnetic attachment using the included accessories. The detachable clip rotates, allowing the microphone to be positioned sideways or inverted while maintaining alignment with the sound source.

Audio Capture

The transmitter records omnidirectional audio with a frequency response of 20Hz to 20kHz and a maximum sound pressure level of 120dB SPL. Equivalent noise is rated at 24dBA. Recording is captured at 48kHz 24-bit when used within a compatible system.

Voice Tone Presets

Three selectable presets adjust tonal output. Regular provides balanced sound, Bright enhances high frequencies, and Rich increases low-frequency presence[4].

Noise Cancellation

Two levels of noise reduction are available. Basic reduces low-level background noise, while Strong reduces higher ambient noise levels[5].

Automatic Limiting

Automatic limiting reduces gain when input levels are too high, preventing clipping during recording[6].

Safety Track

When used with a compatible receiver or app, safety track records a secondary track at -6dB alongside the main track for backup.

Low Cut

Low cut attenuates frequencies below 100Hz to reduce low-frequency noise and is enabled through the DJI Mimo app.

Windscreen

The included windscreen reduces wind noise during outdoor recording. Additional colour options are available separately[1].

OsmoAudio Direct Connection

The transmitter connects directly to supported DJI devices including Osmo Pocket 3, Osmo 360, Osmo Nano and Osmo Action 6 without a receiver[7].

Bluetooth Connection

Bluetooth 5.3 enables direct connection to smartphones for recording and livestreaming in supported third-party apps.

Battery Performance

The transmitter operates for approximately 11.5 hours per charge under standard test conditions[13].

Power Management

Fast charging supports short top-ups, with approximately one hour of use from a five-minute charge[14]. Automatic sleep and power-off functions reduce unnecessary battery drain.

Compatibility

The transmitter works with DJI Mic Mini and Mic Mini 2 receivers, while mobile receiver pairing depends on the selected compatibility mode[3].

DJI Mic Mini 2 Transmitter Specifications

Notes:

[1] Obsidian Black and Glaze White magnetic front covers are included as standard; additional colour options are sold separately.

[3] The receiver supports up to two transmitters, while the mobile receiver supports mixed pairing across Mic Mini 2, Mic Mini, Mic 2 and Mic 3 transmitters.

[4] Voice tone presets are selected via the DJI Mimo app and default to Regular; presets are not available during direct Bluetooth connection.

[5] Noise reduction levels can be adjusted via the DJI Mimo app or supported DJI devices; when connected directly to a phone, Strong mode is applied by default.

[6] Automatic limiting is enabled by default when paired with a receiver and can be adjusted via the DJI Mimo app; behaviour varies depending on connection method.

[7] Transmitters support direct connection to compatible DJI devices via OsmoAudio, with operating time reduced to approximately 7–8 hours in this mode.

[9] Transmitter weight excludes the magnetic clip and magnet.

[10] Device compatibility varies; refer to the DJI Mic Mini 2 compatibility list for supported devices.

[11] Firmware updates and parameter adjustments are managed through the DJI Mimo app.

[13] Operating time figures are measured under controlled conditions and may vary depending on environment and usage.

[14] Fast charging provides approximately one hour of use from a five-minute charge when battery levels are below 25% under test conditions.

[15] Automatic power-saving activates when no signal is detected, with behaviour depending on configuration.

[18] Bluetooth connection supports recording in compatible third-party apps only; native camera apps are not supported.

[20] All data is measured in controlled conditions and actual performance may vary; product images are for reference only and the final product may differ.
