DJI AS2 Speaker

The DJI AS2 Speaker is the onboard loudspeaker for the DJI Matrice 5T. It is there to give instructions, warnings and announcements from an aircraft that reaches the scene before the ground teams: it delivers up to 120 dB measured at one metre, with an effective broadcasting distance of 400 metres and a maximum power of 35 W, in a 194 gram body.

Five modes are available. Live speech from the operator, with echo and feedback suppression, which is the difference between an intelligible announcement and a squeal. Recorded messages, to reuse in recurring situations. Imported audio files, which start playing while the transfer is still running instead of waiting for the upload to finish. Looped playback, for warnings that must repeat unattended. And text-to-speech, which generates the announcement from written text.

Unlike a plain loudspeaker, the AS2 carries strobe lights in five colours — red, blue, green, white and yellow. An aircraft that speaks and flashes is an aircraft that gets noticed: in a noisy scene or at night, the visual signal arrives before the sound.

The protection rating is IP55 and the operating range runs from -20 °C to +50 °C. The accessory can be fitted on its own or alongside the DJI AL2 Spotlight, sold separately, and with both installed the Matrice 5T retains its LiDAR and mmWave obstacle sensing. Speaker functions can be assigned to the customisable buttons on the DJI RC Plus 3 Enterprise remote controller.
