Product Overview

OmniStream™ 238 (AT-OMNI-238) 16-Output IP to Analog Audio Bridge




The Atlona OmniStream™ 238 (AT-OMNI-238) receives audio streamed from OmniStream AV encoders, and delivers up to 16 audio outputs, configurable as eight stereo pairs or 16 mono channels. It is part of the OmniStream Audio Series. The OmniStream 238 and OmniStream AV encoders feature 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 volume 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.

Dante audio networking

The OmniStream 238 is also a Dante networked audio interface. Audinate Dante is a popular audio networking technology widely used in the commercial AV and professional audio industries. With Dante, the OmniStream 238 can be integrated with Dante-equipped DSPs and facility or enterprise-wide distributed audio systems for paging, background music, conferencing, and other applications. (Note: Dante audio over IP routing configuration is necessary for setting up audio streaming from OmniStream encoders to the OmniStream 238, and requires Dante Controllersoftware.)

OmniStream product compatibility

The OmniStream 238 is compatible with OmniStream Pro and OmniStream R-Type encoders, as well as the OmniStream 232 IP / analog audio bridge.


  • Residential whole-house audio systems – The OmniStream 238 can interface directly into multi-room amplifiers. It can be programmed into a control system to allow localized user volume control in separate areas throughout a residence.
  • Bars, restaurants, offices, and other small to mid-sized commercial environments – The OmniStream 238 is ideal for multi-zone audio, as well as delivering background music throughout.
  • Large commercial environments such as convention centers, stadiums, and houses of worship – The OmniStream 238 can be integrated with Dante-equipped DSPs and mixing consoles to distribute audio to designated areas or rooms.
