Auracast Function Guide of Poseidon M100

The Auracast function allows multiple compatible speakers to play music synchronously through Bluetooth broadcasting. The secondary speaker(s) need to join the broadcast created by the primary speaker. The primary speaker acts as the audio source and broadcasts the audio signal to the connected secondary speakers, enabling a “multi-room synchronized playback” experience.
Currently, this function only supports interconnection between Ultimea products equipped with standard Auracast functionality. Connection with products from other brands is not supported at this time.
