Play multiple song files or audio play lists in up to different 6 zones simultaneously from the same PC without appropriating any of a-live's 6 built-in source inputs. a-live allows you to play networked digital music directly from your PC to any and all zones. Streamed audio files can be played from the same play list simultaneously among different zones. For example, if a user is in zone one, and selects a particular song to start playing, a different user in any of the other zones can select the same exact song to play, from the beginning, without interfering with the current play in zone one. Or they could choose to play a completely different song, and aren't limited by having to share a source unit such as an MP3 player or CD player. Most major unprotected formats are supported.
