Technical Overview and Features of the DJI Mic Mini 2 Wireless Microphone System
The DJI Mic Mini 2 is a compact wireless microphone system designed for use with cameras, smartphones, computers, tablets, and DJI Osmo devices. It delivers high-quality 48kHz 24-bit omnidirectional audio and integrates advanced noise cancellation, extended battery life, and broad device compatibility. This system is engineered to meet the needs of content creators seeking precise audio capture and seamless functionality across various platforms.
Audio Recording Capabilities and Noise Cancellation
The DJI Mic Mini 2 offers 48kHz 24-bit audio quality, ensuring clear and detailed sound recording. With a frequency response range of 20Hz to 20kHz, it captures a wide spectrum of audio frequencies. Additionally, a low-cut filter option refines the audio by reducing unwanted low-frequency noise, narrowing the response to 100Hz to 20kHz.
To enhance audio clarity, the system includes two-level noise cancellation, optimized for both indoor and outdoor environments. This feature minimizes background noise, allowing for focused voice capture. The inclusion of Regular, Rich, and Bright voice presets further customizes the sound profile to suit different recording needs.
Wireless Connectivity and Range
Equipped with advanced Bluetooth 5.3 technology, the DJI Mic Mini 2 supports a transmission frequency range of 2.4GHz to 2.4835GHz. This ensures stable connectivity while maintaining low power consumption. The system offers a maximum transmission range of 400 meters for two transmitters and one receiver, while its range adjusts to 300 meters with a mobile receiver and 200 meters in mixed mode.
The GFSK modulation at 2Mbps ensures reliable wireless communication, while an effective isotropic radiated power (EIRP) of less than 20dBm maintains compliance with wireless standards.
Battery Performance and Charging Features
The transmitter of the DJI Mic Mini 2 is powered by a 114mAh battery, offering approximately 115 hours of runtime on a single charge. The receiver, with a 170mAh battery, supports up to 105 hours of operation. Both components include fast-charging capabilities, with the transmitter achieving full charge in 70 minutes and the receiver in 100 minutes.
A noteworthy feature is the charging case, which extends the total runtime to 48 hours. Additionally, a quick five-minute charge provides about one hour of usage, making the system highly efficient for on-the-go recording.
Device Compatibility and Connectivity
The DJI Mic Mini 2 integrates seamlessly with various devices, including cameras, smartphones, tablets, and computers. Its DJI Osmo Audio Direct Connection feature allows up to two transmitters to connect directly to compatible DJI Osmo devices without requiring a receiver. Supported devices include the Osmo Pocket 3, Osmo 360, Osmo Nano, and Osmo Action 6.
For additional flexibility, the DJI Mic Series Mobile Receiver is compatible with the DJI Mic 3, further expanding its application across different devices. This ensures smooth audio recording for a wide range of professional and personal projects.
