AT-OMNI-238

8

The Atlona OmniStream™ 238 (AT-OMNI-238) receives audio streamed from OmniStream 512 encoders, and delivers 

up to 16 audio outputs, configurable as eight stereo pairs or sixteen mono channels. It is part of the OmniStream 

R-Type Series, designed for high performance, flexible distribution of AV over Gigabit Ethernet in residential and light 

commercial applications. OmniStream features industry standard, AES67-compatible audio over IP streaming. Up 

to sixteen channels of PCM audio can be received by the OmniStream 238. An audio stream can be routed to one 

or more unbalanced or balanced outputs, each with programmable gain control. The OmniStream 238 is ideal for 

feeding audio from HDMI sources into a whole-house audio system, as well as multiple audio zones in a commercial 

AV application.

To ensure stable connection, disable 802.3 Energy Efficient Ethernet (EEE) on connected Ethernet switches.

OmniStream requires AMS 2.0 (Atlona Management System) for discovery and management. 

AMS 2.0 is 

available from https://atlona.com/AMS for free. Two options can be used for installation: The free Linux based 

software download or the easy to install server hardware (AT-AMS-HW).

the same network.
