OmniStream Dual-Channel Dante Networked Audio Interface
AT-OMNI-232
The Atlona OmniStream™ AT-OMNI-232 is a Dante™ networked audio interface that transmits
and receives two channels of audio over a network. OmniStream is designed for distributing AV
over Gigabit Ethernet in enterprises and other large-scale installations. AT-OMNI-232 devices
are ideal for integrating microphones and other audio sources with a Dante-equipped DSP and
OmniStream AV decoders. The AT-OMNI-232 features two balanced mic/line audio inputs with
selectable 24 volt phantom power, as well as two balanced line level outputs. It can be powered
over the network though Power over Ethernet (PoE), as well as from local AC power. The AT-
OMNI-232 extends the power and exibility of the OmniStream networked AV platform, by
enabling facility-wide system designs that include complete audio system integration with Dante-
based professional audio devices.

Operating Notes
• To ensure stable connection, disable 802.3 Energy Ecient Ethernet (EEE) on connected
Ethernet switches.
• OmniStream requires the Atlona Management System (AMS) which provides discovery, and
management. AMS is a free application that can be downloaded from the Atlona web site at
http://atlona.com/product/at-sw-ams/.
• Connection issues may occur if control software is used over VPN. Ensure the software and
OMNI-232 are on the same network
IMPORTANT: Visit http://www.atlona.com/product/AT-OMNI-232 for the latest rmware
updates and documentation.

microphones, receivers (or other
audio sources) with line level
outputs using the included captive
screw connectors. Either balanced
or unbalanced connections may be
used.
NOTE: Phantom power is set to o by default, to ensure
MICs without phantom power are not damaged
NOTE: Use of a jumper is needed between negative

Mounting Instructions
The AT-OMNI-232 includes two mounting
brackets and four mounting screws, which can
be used to attach the unit to any at surface.
1 Using a small Philips screwdriver, remove
the two screws from the left side of the
enclosure.
2 Position one of the rack ears, as shown
below, aligning the holes on the side of
the enclosure with one set of holes on the
rack ear.
3 Use the enclosure screws to secure the
rack ear to the enclosure.
4 To provide added stability to the rack ear,
use two of the included screws and attach
them to the two holes, directly below the
enclosure screws, as shown above.
5 Repeat steps 1 through 4 to attach the
second rack ear to the opposite side of
the unit.
6 Mount the unit using the oval-shaped
holes, on each rack ear. If using a
drywall surface, a #6 drywall screw is
recommended.

Auto IP mode
If no DHCP server is detected after 30 seconds, then the encoder will be placed in Auto IP mode
and will be assigned a link-local IP address of 169.254.XXX.XXX.
IP
DHCP mode
By default, the OmniStream 232 is set to DHCP mode. In this mode, each encoder that is
connected to the Local Area Network (LAN), will automatically be assigned an IP address by the
DHCP server.
3. Connect captive screw connectors from LINE OUT ports to audio players/distribution
devices. e.g. AT-PA100-G2
4. Log onto a local network computer and use the Dante Controller and AMS software to
adjust device and audio settings. See page 4 for software instructions

Software
Dante Controller
For network setting changes, nding IP, and I/O audio switching, Dante Controller is needed.
To download the software, go to http://www.audinate.com. The software will be found under
products > software > Dante Controller. The download button is found on the right side of the
page. Follow the instructions for downloading.
Once downloaded and installed, the AT-OMNI-232 will be automatically detected as long as the
PC running Dante Controller and OmniStream 232 are on the same network.
AMS
AMS is used for adjusting device settings such as: input volume, output volume, phantom power,
and updating.
1 Download AMS software from http://atlona.com/products/AT-SW-AMS/
2 Launch the Atlona Management System app.
3 Launch a web browser and enter localhost:8080 in the address eld.
4 Enter the login information on the AMS web page, then click the Login button.

Troubleshooting
Problem Cause Solution
PWR indicator is o. No power. • If using a PoE-capable
switch, make sure that the
port on the switch that is
connected to the encoder,
has PoE enabled. When the
encoder is powered using
PoE, the PWR indicator will
be green.
• Check the Ethernet cable for
possible damage or loose
connections.
• Connect the optional 24V
DC power supply (AT-PS-
24250-L is available from
Atlona.com). When using an
external power supply, the
PWR indicator will be red.
OmniStream not displayed
in AMS.
Unable to locate DHCP
server on network.
• Verify that the encoder is
connected to a network with
a DHCP server.
• Inspect the Ethernet cable
between the encoder and
the network switch. All
connections should be
secure and the cable should
be in good condition.
• If a DHCP server is not
found within 30 seconds, the
encoder will default to Auto
IP mode. In this mode, an IP
address within the range of
169.254.xxx.xxx will be
assigned to the encoder.
