Functions

IP network audio streaming – plays audio directly from a central server or network audio collectors
Autonomous operation (offline mode) – scheduled playlists and programs are automatically stored on the SD card and continue playback even if the network connection is lost
Automatic time synchronization – the internal real-time clock synchronizes with the system server, ensuring accurate schedules without manual adjustment
Scheduled and timed playback – precise playback of background music or announcements at predefined times
Background, business and emergency broadcasting – supports three broadcasting levels with priorities; emergency messages always have the highest priority
Watchdog and data error correction – ensures stable, uninterrupted operation and accurate audio transmission
