-Two relay-bypassed HD/SD-SDI inputs with access to all audio channels
-Dual, independent compensating video delays
-Up to 16 channels of audio via Livewire+/AES67
-Includes all standard xNode controls including front panel and web interface

SDI xNode builds upon the success of the popular Axia® xNode by de-embedding two separate HD/SD-SDI inputs and converting up to 16 channels of audio to the Livewire+/AES67 Audio over IP formats. The audio is available as a Livewire® network source or can be re-embedded into two separate SDI output streams.

SDI xNode brings the power and flexibility of the Axia Livewire AoIP (Audio over IP) format to broadcast television for the first time by de-embedding two incoming SDI streams and making that audio available on a Livewire network.

Facilities can now easily and efficiently de-embedded audio from SDI input (up to 16 channels) and route to any or all Livewire+/AES67 compliant devices in the plant.

Additionally, audio pairs from either incoming SDI stream - once converted to Livewire – can be shuffled and re-embedded to either SDI output stream with matched audio/video latency.


Since 2003, broadcast facilities have been using Axia Livewire AoIP (Audio over IP) technology to route hundreds of audio channels using standard Ethernet switches, cables, and other components. With thousands of devices on the air every day, reliability is proven.

Livewire is lightning fast, simple to implement, easy to manage, and now as Livewire+, fully compliant with the AES67 standard and ready to incorporate new standards as they are developed. It also significantly reduces the number of cables and wires needed to transport and share audio throughout the entire broadcast plant.

Nearly Any audio source – analog or AES, and now SDI – and myriad equipment from phone systems to codecs to satellite receivers – can be a part of the Livewire network.


Auto-sensing HD/SD-SDI with de-embedding of up to 16 channels total; de-embedded audio can be routed to Livewire output and/or re-embedded to the SDI output with SMPTE 292M (HD-SDI) and SMPTE 259M (SD-SDI) support

Full Livewire and AES67 compatibility

Livewire at audio input, SDI-delivered audio clock at output. SDI clock can be provided to Livewire network if desired.

Two RJ-45 100BASE-T connections available for management or AoIP interface.
