The DJI AS1 Speaker is a compact loudspeaker payload for the DJI Matrice 4 Series, letting your crew broadcast live voice or pre-recorded audio directly from the aircraft during airborne operations.
Lightweight, tool-free to fit and purpose-built for public-safety, inspection and communication missions where clear messaging from altitude matters.

The AS1 Speaker turns your DJI Matrice 4E or DJI Matrice 4T into an airborne broadcast platform. Delivering up to 15 W of output and a maximum volume of 114 dB at 1 m, it is designed to project clear announcements across open areas during search, crowd management and site communication tasks.
Under DJI laboratory conditions at 25 degC, the AS1 reaches an effective broadcast distance of up to 300 m. Real-world results depend on software version, audio source, environment and other factors, so these figures should not be treated as guaranteed field performance.
Four broadcast modes
Real-time broadcasting (with echo suppression), recorded broadcasting, media import with simultaneous transmission and playback, and text-to-speech give crews flexible ways to deliver a message.
Compact and light
Just 92.5 g including the bracket (around 90 g without), the AS1 keeps payload weight low while mounting securely to the Matrice 4 Series.
Tool-free mounting
Quick-release, hand-tightened screws allow fast fitting and removal in the field without tools, so you can switch payloads between missions.
Built for the field
An operating temperature range of -20 degC to 50 degC supports deployment across demanding environments and seasons.
Flexible broadcasting modes
Real-time broadcasting supports echo suppression and requires the latest firmware. Recorded broadcasting lets you prepare messages in advance. Media import supports simultaneous transmission and playback. Text-to-speech requires the latest firmware and currently supports Chinese and English only.
