DJI has officially launched the Mic Mini 2S, a compact wireless microphone system featuring 32-bit floating-point audio recording, AI-powered noise cancellation, and a 40-hour total battery life. Designed for content creators and filmmakers, the system supports up to four transmitters per receiver, with the transmitter weighing only 12 grams and offering up to 400 meters of wireless transmission range.
How 32-Bit Floating-Point Recording Changes Field Audio
The primary technical shift in the DJI Mic Mini 2S is the inclusion of 32-bit floating-point internal recording. According to DJI, this technology eliminates the risk of audio clipping or distortion during sudden volume spikes, such as loud bursts of sound or unexpected environmental noise. By capturing a wider dynamic range, the system removes the need for constant manual gain adjustments in the field, allowing editors to recover audio details from both quiet whispers and high-decibel peaks during post-production.
What Are the Benefits of AI-Powered Noise Cancellation?
DJI has integrated an AI-driven algorithm into the Mic Mini 2S to manage environmental noise, offering two distinct modes based on recording conditions. The “weak” mode is optimized for indoor settings to suppress low-frequency hums from HVAC systems or computer fans. The “strong” mode is engineered for outdoor environments, specifically targeting wind noise and heavy traffic. This dual-mode approach allows users to maintain clear, intelligible vocals without the need for complex external audio processing hardware.
How Does the Four-Transmitter System Work?
The Mic Mini 2S introduces a significant expansion in multi-person recording capabilities. A single receiver can now pair with up to four transmitters simultaneously. This configuration is particularly useful for panel discussions, group interviews, or multi-source documentary setups. The system supports mono, stereo, and four-channel output, allowing sound designers to isolate and mix each speaker’s audio track independently. Furthermore, the new receiver maintains backward compatibility with previous DJI Mic Mini models.
Battery Life and Field Performance
Power management remains a critical focus for mobile production kits. The Mic Mini 2S transmitter provides 11 hours of continuous use on a single charge, while the receiver offers 10 hours. When utilizing the included battery-equipped charging case, the total runtime extends to 40 hours. In scenarios requiring rapid turnaround, the system’s fast-charging capability provides one hour of operation from just five minutes of charging.
Pricing and Availability
As of the initial launch in the Chinese market, DJI has structured the system into various tiers to accommodate different production needs. The professional full set, which includes one receiver, two transmitters, and a charging case, is priced at 1199 Yuan (approximately $165). For mobile-first users, a smartphone-oriented kit is available for 629 Yuan, while individual transmitters can be purchased for 399 Yuan (approximately $56). Global release dates and localized pricing have not yet been confirmed by the manufacturer.
