DJI has unveiled its latest wireless microphone system, the DJI Mic 3, which manages to pack a range of professional-level features into a smaller and lighter build. It is aimed at creators, videographers, and journalists who need clear and reliable audio in different types of shooting environments.
The Mic 3 follows the success of earlier versions but adds some important new capabilities. It now includes 32-bit float internal recording, built-in timecode support, and smarter gain control, all of which are designed to make both recording and editing audio easier and more reliable.
Key Takeaways
- Smaller and lighter design: The transmitter weighs only 16 grams, making it much lighter than the Mic 2.
- 32-bit float recording: Supports dual-file recording that prevents audio clipping and provides flexibility in editing.
- Timecode integration: Built-in support allows for precise syncing of audio with multi-camera video setups.
- Adaptive gain control: Automatically adjusts levels to prevent distortion and manage sudden volume spikes.
- Extended battery life: With the charging case, the system can last up to 28 hours of use.
One of the most noticeable updates is the transmitter itself. It is compact and can be attached with either a magnetic clip or a traditional clip-on mount. Despite its size, it has enough onboard storage for up to 57 hours of 24-bit audio or 14 hours of 32-bit float recording. This makes it a strong backup option in case wireless transmission is interrupted. The dual-file recording feature is also a major advantage since it saves both an untouched track and an algorithm-enhanced version.
The receiver has been given a few practical upgrades too. It features a 1.1-inch AMOLED touchscreen and a dial that allows for quick adjustments. It can connect up to four transmitters at once, outputting separate tracks for each person. This multi-channel option, called Quadraphonic mode, works with select Sony cameras and specific computer software, making it especially useful for interviews or group discussions.
Connectivity options are fairly wide. The Mic 3 can connect to cameras through a 3.5mm TRS cable, or directly to smartphones and computers using USB-C. It also supports direct Bluetooth connection to compatible DJI cameras such as the Osmo 360 and the Osmo Action 5 Pro, removing the need for a receiver in those cases.
DJI has also added software features that expand its usefulness. There are three tone presets to shape the voice: Regular for a natural balance, Rich for fuller sound, and Bright for clearer vocals. Noise cancellation is available in two levels, and the new adaptive gain modes help keep volume under control. Automatic mode reduces the risk of sudden audio spikes, while Dynamic mode adjusts levels to stay consistent over time.
Wireless range is another strength, reaching up to 400 meters. The Mic 3 achieves this by automatically switching between the 2.4 GHz and 5 GHz frequency bands to maintain a steady signal.
There are, however, a couple of design trade-offs. Unlike the Mic 2, the new transmitter no longer includes a 3.5mm input for an external lavalier microphone, which means the transmitter itself will be visible on camera. For shoots that require a clean look, that might be less than ideal. The lightweight design also means that on very thin shirts or collars, the clip can sometimes cause fabric to sag or fold.
Even with those minor compromises, the DJI Mic 3 feels like a strong step forward. It combines portability with advanced audio tools in a way that makes it appealing for a wide range of creators who want high-quality sound without a bulky setup.
Frequently Asked Questions
Q. What is 32-bit float recording and why is it useful?
A. 32-bit float recording is a type of digital audio format that captures a wide dynamic range. This means it can record both very quiet and very loud sounds without audio clipping or distortion. It is useful because it gives creators more room to adjust audio levels in editing without losing sound quality.
Q. Can the DJI Mic 3 be used with any camera or smartphone?
A. Yes, the DJI Mic 3 can be used with a variety of devices. The receiver unit has a 3.5mm TRS output for cameras and a USB-C port for connecting to smartphones or computers. It also connects to some DJI products directly via Bluetooth.
Q. How is the DJI Mic 3 different from the Mic 2?
A. The DJI Mic 3 is smaller and lighter than the Mic 2. It also adds new features like adaptive gain control, timecode support, multi-channel output (up to four transmitters), and a longer total battery life. However, unlike the Mic 2, the Mic 3 transmitter does not have a 3.5mm audio input for a separate lavalier mic.
