User Manual “Instreamer“ - V3.17 - 25th July 2011
1 Introduction
1.1 About the “Instreamer” firmware
The “Instreamer” firmware is designed to ser e as a
ersatile, network-enabled analog and digital audio-
to-Ethernet con erter for commercial audio
distribution.
The “Instreamer” firmware con erts audio from any
analog or digital de ice 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, ia an IP-based network
or the Internet, to one or more recei ers or Shoutcast
/ Icecast-ser ers.
Barix de ices running the “Instreamer” firmware can
be easily managed ia a web browser interface using
PCs, web pads, PDAs or other web-enabled de ices.
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
de ice can also be integrated with other
components, controlled by automation systems, or
used with Barix Exstreamers to create more flexible,
more cost-effecti e distributed audio systems.
The built-in serial interface allows data to be relayed
to another Barix de ice, a PC or a ser er using the
“Serial Gateway” functionality of the “Instreamer”
firmware.
With an optional stick-on transmitter, additional IR-
enabled de ices can be remote controlled ia the
network connection, enabling users to control their
audio sources without being in the same location as
the de ice.

De ice Configuration 1

User Manual “Instreamer“ - V3.17 - 25th July 2011
3.1 Network settings
This chapter explains how to adjust the network
settings of the Barix de ice.
We recommend that you set a Static IP address.
With a static (permanent) IP address the de ice does
not ha e to get a new IP address at power on or
reboot.
IP Address
Enter the 4 alues of the desired static IP address
e.g.:
•“192.168.0.12” for an internal LAN
Attention: Make sure that you enter a free IP
address. The de ice will check this and will not be
a ailable until the de ice using the same IP is
disconnected or switched off. The command Ping
can be used to ensure that a specific IP address is
unused (i.e. No reply).
The automatic disco ery functions are not executed
if a Static IP address is set.
16 De ice Configuration

User Manual “Instreamer“ - V3.17 - 25th July 2011
The automatic options are as follow:
•“0.0.0.0” for automatic disco ery (Disco ery order:
BOOTP, DHCP, IPzator, AutoIP)
To enable automatic disco ery but disable certain IP
disco ery functions set all but the third alue to zero.
For each function you want to disable add the alue
from the table below:
•“0.0.1.0” to disable AutoIP
•“0.0.2.0” to disable DHCP
•“0.0.4.0” to disable BOOTP
•“0.0.8.0” to disable IPzator
Examples:
•“0.0.3.0” disables AutoIP and DHCP
•“0.0.11.0” disables all but BOOTP
Attention: “0.0.15.0” disables all disco ery
functions which locks you out unless you reset the
de ice to factory defaults by pressing the reset
button for about 10 seconds.
Netmask
Enter the 4 alues of the desired Netmask e.g.:
•“0.0.0.0” for a default Netmask depending on the
IP Address used
•“255.255.255.0” for a C class network
Note: Try first the Netmask your PC is set to or ask
your Network Administrator.
De ice Configuration 17

User Manual “Instreamer“ - V3.17 - 25th July 2011
Gateway IP Address
A correct setting of the Gateway IP address is
needed to stream to the Internet or to destinations
outside your local network (LAN).
Enter the 4 alues of the desired Gateway IP
address e.g.:
•"0.0.0.0" for no Gateway or automatic disco ery
•"192.168.0.1" for a Gateway in a LAN
Note: If you ha e set the de ices IP address to
automatic disco ery and your ser er or router has
issued an IP address then most probably it also has
supplied a alid Gateway address, “0.0.0.0” will then
work fine.
If you ha e set a Static IP address then you will need
to configure a alid Gateway address manually. Try
first the same Gateway IP address your PC is set to.
If it doesn’t work then ask your Network
Administrator for a correct Gateway IP address.
DHCP Host Name
From ersion VB3.17 a DHCP host name can be
configured for the de ice. If this field is left blank then
the de ice creates a DHCP name using part of the
Ethernet MAC address e.g.“CO1ED04” where ED04
are the 2 least significat bytes of the MAC.
Use SonicIP
If “Use SonicIP” is set to yes, the de ice will
announce its IP address o er the audio output during
start up.

3.2 Audio settings
This chapter explains how to adjust the audio input
and output settings of the Barix de ice.
Input source
Choose the desired input source. Line mono and
MIC input are mono, the other settings are stereo.
The options a ailable depend on the HW according
to the table below.
The Exstreamer 500 and Exstreamer 1000 ha e
external Analogue to Digital circuitry which support
input speeds of 32 and 48kHz. The selection
pro ides a better input signal to noise ratio, howe er
the A/D gain is fixed and cannot be adjusted.
Default setting is "Line stereo".

Encoding & Frequency
Choose between six different MP3, 8 G.711 and 13
PCM encoding settings. The bit rate used for 8 and
24kHz G.711 and PCM is displayed in kbit/sec. in the
table below.
Encoding / Sampling

G.711 8bit (uLaw or aLaw) 64 192
PCM 16bit 128 384
For MP3 a erage bit rates see the next section.
Note: In case of S/PDIF input, if MPEG1 is used the
sampling frequency is auto detected (32, 44.1 or 48
kHz). For uncompressed formats the sampling
frequency must be set to match the input, the coding
type does not matter.
Encoding Quality
This parameter applies only when MPEG encoding is
selected in the pre ious parameter. Choose between
"0 lowest" and "7 highest" in steps of 1. The encoder
quality table below shows the a erage bit rate in
kilobits per second for the quality settings and
sampling frequencies in kHz using mono input with
MS-Stereo encoding disabled.
