CZI MP140 Long-Range Broadcasting System

The CZI MP140 is a professional-grade long-range aerial acoustic system for the DJI Matrice 300 RTK and Matrice 350 RTK, delivering a maximum output of 140 dB and effective broadcast range exceeding 1,000 meters. Built for large-scale public address, border control, disaster response, and mass communication from altitude, the MP140 reaches audiences that no ground-mounted speaker system can cover without extensive fixed infrastructure.

Operating at 150W, the MP140 supports multiple broadcast modes including real-time live voice, multi-language text-to-speech, pre-recorded audio playback, and music with automatic volume adjustment. A built-in 3-axis anti-shake micro-gimbal with a 1080p camera provides visual confirmation of broadcast targets, and a handheld microphone controller with a tilt range of 0 to 80 degrees lets operators direct sound with precision. Supported audio formats include MP3, WAV, M4A, FLAC, and AAC for broad compatibility with existing audio assets.

Weighing 2.7 kg and mounting via quick-release adapter ring, the MP140 is designed for teams who require broadcast capability at a scale normally reserved for fixed infrastructure. At 4,600 dollars, it is the top-tier aerial broadcasting payload available for the Matrice 300/350 platform.
