User Manual “Instreamer“ - V3.17 - 25th July 2011

1 Introduction

1.1 About the “Instreamer” firmware

The “Instreamer” firmware is designed to serve as a
versatile, network-enabled analog and digital audio-
to-Ethernet converter for commercial audio
distribution.

The “Instreamer” firmware converts audio from any
analog or digital device into G.711 (8 bit), PCM (16
bit) or high-quality MP3 streams. The audio is
encoded in real-time, and the generated audio
stream can be distributed, via an

IP

-based network

or the Internet, to one or more receivers or Shoutcast
/ Icecast-servers.

Barix devices running the “Instreamer” firmware can
be easily managed via a web browser interface using
PCs, web pads, PDAs or other web-enabled devices.
SNMP remote monitoring capabilities allow for
building a manageable distributed audio network.
With serial and Ethernet control APIs, open

IP

-

standards, and the standard encoding formats, the
device can also be integrated with other
components, controlled by automation systems, or
used with Barix Exstreamers to create more flexible,
more cost-effective distributed audio systems.

The built-in serial interface allows data to be relayed
to another Barix device, a PC or a server using the
“Serial Gateway” functionality of the “Instreamer”
firmware.

With an optional stick-on transmitter, additional IR-
enabled devices can be remote controlled via the
network connection, enabling users to control their
audio sources without being in the same location as
the device.
