General Audio Distribution Applications

The principle for your system should be as following:

a) every source is either

1 using an Instreamer or
2 is one "channel" (background music) generated by our MP3_RTP_Streamer software on a PC.

This is free software, on our website here: http://www.barix.com/downloads/Software_tools/221/ Documentation is also on the site.

3 you can also use an Exstreamer (!) to generate a radio channel from a file/playlist on a USB stick. With a 4GB USB Stick,

such a file can be quite long (several days, depending on audio format), and this can be used ideally for a solid state, low power, constant stream generator for background music. The software for the Exstreamer is not yet released but we can provide a copy to check it out.

b) Annuncicom has contact closure inputs, and can be set to start streaming on contact closure with a higher priority than the other sources (even higher than paging), so all Exstreamer devices will immediately switch to the Annuncicom feed.

c) Channel selection: channel selection can also be done by multiple means

1 using a browser (or iPhone etc), directly controlling the Exstreamer
2 using a command interface on the Exstreamer from an automation system (such as Crestron)
3 using a remote control with the Exstreamer
4 using the VSC (Volume Source Control), connected to the Exstreamer
5 using central software (for example, ICGraph)

ICGraph is a general system monitoring, paging and intercom software. It can be used to control a system as above, switch the channel an Exstraemer listens to, make announcements from the PC, work as an intercom console etc. It is *not* generating background music channels, that is done by the MP3_RTP_Streamer software.
