The DJI AS2 Speaker mounts under the DJI Matrice 5T and is quoted to broadcast up to 400 m, reaching 120 dB at 1 metre in DJI’s laboratory tests at 25°C. It is an optional payload for the handheld Matrice 5T only: it does not fit the docked Matrice 5TD, and it does not fit Matrice 4. See the Matrice 5T category for the aircraft and the matching spotlight.
It supports live talk with echo suppression, recorded messages, imported audio and text-to-speech, and can loop a message. A five-colour warning light (red, blue, green, white and yellow) is built in, which helps a crew pick the aircraft out during a search. It is rated IP55, weighs 194 g, measures 96 × 70 × 66 mm and draws up to 35 W. Operating temperature is −20°C to 50°C. Real results vary with software, audio source and environment.
It can be flown on its own or with the DJI AL2 Spotlight. If both are fitted, install the spotlight first, then the speaker. After it is on, activate it and calibrate the compass in DJI Pilot 2. It will cut some flight time, so plan the battery count accordingly. Do not use it close to people, and do not play single-frequency tones, which can damage the speaker.
