OmniStream Dual-Channel Dante™ Networked Audio Interface

The Atlona OmniStream™ 232 (AT-OMNI-232) is a Dante networked audio interface that transmits and receives two channels of audio over a network. OmniStream 232 devices are ideal for integrating microphones and other audio sources with a Dante-equipped DSP and OmniStream AV decoders. The OmniStream 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 OmniStream 232 extends the power and flexibility of the OmniStream networked AV platform, by enabling facility-wide system designs that include complete audio system integration with Dante-based professional audio devices.

OmniStream was engineered from the ground up at Atlona to deliver the performance and dependability of traditional AV distribution, with the virtually unlimited scalability and cost efficiency of integrating over data networks. It addresses the many challenges AV and IT integrators encounter with implementing networked AV systems, while delivering immediate and long-term ROI to end users in enterprises and other organizations.

Dante Audio Networking

The OmniStream 232 integrates audio with data networks using Audinate Dante, a popular audio networking technology widely used in the commercial AV and professional audio industries. For facilities with conference or meeting rooms, it is ideal for integrating microphones onto the network for processing by a Dante-enabled DSP, or incorporating into a larger Dante audio system for applications such as paging, recording, or sharing microphone resources between rooms. Additionally, this audio interface works with an OmniStream AV decoder for processing de-embedded audio streamed over the network, and embedding Dante audio for playback through a display.


The OmniStream 232 is ideal for use in:

  • Installations with meeting rooms and other spaces with several microphones
  • Enterprises and other large organizations with a need for complete AV system solutions that include professional-quality audio for conferencing and sound reinforcement
  • Facilities in which Dante audio systems are already in place, or are being planned

Product Compatibility

The OmniStream 232 is compatible with the OmniStream 121 and OmniStream 122 decoders as an interface between OmniStream VC-2 streams and Dante audio streams. It is also compatible with third-party Dante networked audio devices for inclusion in networked audio systems.

Configured and Managed by AMS

OmniStream is configured, controlled, and managed using the Atlona Management System (AMS), a powerful network software platform for IP-controllable Atlona products. AMS is essential for accessing all capabilities of the OmniStream encoders and decoders, including AV and control routing between sources and destinations, configuring OmniStream dual-channel encoders and decoders for independent or redundant streams, monitoring the status of OmniStream endpoint devices, powering displays on or off through automatic display control, and more. AMS is also used for Dante network configuration with the OmniStream 232 networked audio interface.

Dual-channel Dante networked audio interface

  • Expand the capabilities of OmniStream networked AV systems by integrating audio devices and digital signal processing*
  • Allows a unified AV-over-IP platform for facility or enterprise-wide audio and video distribution
  • The OmniStream 232 uses the Dante networked audio protocol, and operates independently from VC-2 streams and OmniStream AV encoders and decoders

Two balanced mic/line inputs

  • Provide a localized audio connection for microphones, or de-embedded audio from an OmniStream AV decoder
  • Avoids the need to run long mic cables to an equipment rack

Selectable 24 volt phantom power for each input

  • Delivers the appropriate power necessary for a condenser microphone
  • Ensures compatibility with the wide range of popular phantom-powered microphones used in pro AV systems

Two balanced line level outputs

  • Deliver Dante audio to an OmniStream AV decoder for embedding onto an HDMI output, or send to a local sound reinforcement system
  • Enables flexible system design options for audio playback in a facility

Selectable input and output gain settings

  • Set up for mic and program audio reference levels, as well as interfacing with pro or consumer audio equipment
  • Simple built-in controls for setting proper audio gain structure and delivering quality performance

Local or PoE (Power over Ethernet) powering

  • Device can conveniently be powered over the network from a PoE-equipped network switch
  • PoE simplifies integration without the need for local AC power, and allows centralized power monitoring and management

Configured and managed by AMS

  • AMS is the essential software tool for accessing all capabilities of OmniStream, including AV and control signal routing, system monitoring with instant alerts, and more
  • Integrates OmniStream device configuration, management, and updates to reduce installation time and enable remote support

Award-winning 10 year limited product warranty

  • Ensures long-term product reliability and performance in residential and commercial systems
  • Specify, purchase, and install with confidence
