Radio Streaming
You can stream and multicast online radio or loop a preconfigured audio file to multiple devices simultaneously.
This allows centralized audio distribution without requiring individual playback control on each device.
Note
For 8301, make sure Additional Features → Input/Output → Audio Always On is set as Disabled before using Radio Streaming.
Otherwise, you cannot enable Radio Streaming.
Supported Radio or Audio Format
Make sure your audio meets the following requirements:
Radio streams: The stream must be an HTTP or HTTPS audio stream encoded in MP3, AAC, AAC+, Ogg Vorbis, Opus, or FLAC. HLS (.m3u8) audio streams are also supported.
Offline audio files: Each file must be in MP3 format, smaller than 200 MB or shorter than 3 hours at 128 kbps.
Otherwise, the file is not available in the Offline Music File drop-down list for Radio Streaming.
Uploading Offline Audio Files
To play offline audio files, you must upload them to the radio folder of the File Manager before you can use them in radio streaming.
