DJI Mic 3 Wireless Microphone System DMR03 Manual

Introduction

The dji Mic 3 Wireless Microphone System DMR03 is a compact wireless audio solution for creators who need clear speech, flexible connectivity, and a streamlined recording workflow. The system is designed for video production, interviews, livestreams, online lessons, podcasts, presentations, and mobile content creation.

Its receiver supports camera, smartphone, computer, and wireless workflows, while compatible DJI devices can connect directly to transmitters through the DJI OsmoAudio ecosystem. This can reduce the amount of equipment needed when recording with supported Osmo cameras. The system also supports mono, stereo, and quadraphonic recording modes, making it suitable for solo creators, interviews, and multi-person productions.

Depending on the selected kit, the package may include one or two transmitters, a receiver, and a charging case. A two-transmitter configuration is practical for interviews and two-person videos, while a single-transmitter setup suits individual creators. The transmitters and receiver are linked at the factory in the same combination, allowing quick setup.

Use the DJI Mic 3 when portability, dependable wireless transmission, and adaptable audio routing are more important than using a traditional wired microphone. For the cleanest results, position each transmitter near the speaker’s mouth, avoid rubbing clothing against the microphone, and monitor input levels before recording.

How to Set Up the DJI Mic 3 Wireless Microphone System

Place the transmitters and receiver in the charging case. Charge the system before the first recording session.
Remove the transmitter and receiver from the case and power them on. Units included in the same kit are normally linked automatically.
Attach each transmitter securely to clothing near the speaker’s upper chest. Keep the microphone opening unobstructed and away from zippers, necklaces, and loose fabric.
Connect the receiver to a camera using the appropriate audio connection, or connect it to a smartphone or computer with a supported adapter or cable.
Open the receiver controls and select Mono, Stereo, or Quadraphonic mode according to the recording setup.
Adjust input levels while the speaker talks at the expected volume. Make a short test recording before starting the main session.
For direct DJI device recording, pair the transmitter with a compatible Osmo product using that device’s wireless audio settings.

If pairing fails, return both units to the charging case and restart the case. For manual pairing, swipe down on the receiver screen, select Device Linking, choose an available transmitter slot, and hold the transmitter linking button until the connection completes.

Keep the equipment dry, avoid blocking ventilation openings on connected devices, and do not use damaged cables, batteries, or housings.

DJI Mic 3 Troubleshooting Guide

No sound is recorded

Confirm that the receiver is connected to the correct camera, phone, or computer input. Check the recording application’s audio source, raise the input level carefully, and verify that the transmitter is powered on and linked.

Transmitter and receiver will not connect

Place both devices in the charging case, switch the case off and on, and try again. If automatic linking does not work, use Device Linking on the receiver and hold the transmitter linking button. A stable connection indicator confirms successful pairing.

Audio contains clothing noise

Reposition the transmitter so the microphone opening faces outward. Use the included wind protection when appropriate, keep the transmitter away from fabric movement, and secure loose cables or accessories.

Wireless audio drops out

Reduce the distance between the transmitter and receiver, maintain a clear line of sight, and move away from crowded wireless environments. Metal structures, walls, vehicles, and other radio equipment can reduce operating range.

Audio clips or sounds too quiet

Check the receiver’s level settings and perform a test recording. Ask the speaker to maintain a consistent distance from the transmitter. If clipping continues, reduce the input level before recording.

Firmware or compatibility problems

Use the DJI Mimo app or official DJI support tools to check for available firmware updates. Record the product model, connected device, operating system, and exact symptoms before requesting assistance.

For warranty service, retain proof of purchase and contact DJI through its official support center or regional service channel. Warranty duration and service procedures can vary by product, component, and country.
