The Barix IP AUDIO MODULE 300 is a versatile network audio de-coder
module that plays AAC+, MP3, Ogg Vorbis, WMA, G.711 and PCM audio.
It is easily incorporated into applications to play files and playlists from USB memory, PC or web server (http), or to stream from sources like Shoutcast, Icecast (Internet radio) or RTP servers.
Common Applications are:
- Playing audio from PC, jukebox applications, flash memory
- Multiroom or multizone distributed audio systems
- Commercial audio streaming applications (airports, hotels, etc.)
- Realtime audio bridging over IP (when used with the Instreamer)
- Paging and announcement applications
- Instore audio distribution (realtime) for retail, restaurants, franchises
Installing a device containing the IP AUDIO MODULE 300 is fast and simple:
After power-up the module will either get an IP address automatically
(BootP or DHCP), or will find one using the IPzator feature. The unique SonicIP feature then announces the IP address over the audio outputs! The module is easily configured and controlled by a standard web browser.
There are 3 firmware options for the IP Audio Module 300. Exstreamer Standard firmware for jukebox and multizone applications,
Exstreamer Streaming Client firmware for commercial streaming
applications with AAC+, WMA, Ogg Vorbis and MP3 support, automatic
failover (up to 3 URL's / playing from USB memory) and monitoring
capabilities or ABCL development kit: a simple to use, powerful Basic dialect allows for custom application development. (please see the ABCL programmers manual & technical doc.)
The IP AUDIO MODULE 300 supports various control and communication
modes. Software developers can easily write audio applications using one of the openly documented Ethernet (cgi, TCP, UDP) or serial interfaces (API).
For hardware integration a technical document with schematic, pin-out and suggestions for the layout of a custom carrier PCB is available. For evaluation purposes, Barix recommends any Barix Exstreamer labelled "AAC+ capable".
While the Barix IP AUDIO MODULE 300 decodes only, the Barix
IP AUDIO MODULE 100 can decode as well as encode, providing S/PDIF
as well as analog audio interfaces.
- Decodes AAC+, MP3, OggVorbis, G.711 and PCM formats from network, local flash memory or local USB memory
- 10/100 Mbit Ethernet connection
- Controllable by web browser and API
- Standard and fully programmable ABCL (Basic dialect)firmware versions available (OEM versions on request)
