The AVN commentary units offer AoIP technology with flexible configurations to suit different broadcasting needs. Whether you need to cover single operators or full commentary teams, the AVN range will deliver professional-grade, networked audio solutions with unmatched quality and reliability.
These new Dante® audio interfaces convert balanced analogue or AES3 inputs and outputs to Dante AoIP. For analogue I/O, 4 and 8 channels bidirectionally, 16 channel inputs and 16 channel outputs are catered for. On these analogue products, global line up level can be set for inputs and outputs. For AES3 there is an 8 stereo channel bidirectional interface. All analogue and AES3 models can be ordered with either single or dual redundant Dante ports. Simple to configure and operate, these cost effective rack-mount solutions offer an easy solution for AV professionals and system integrators.
These simple plug and play audio interfaces provide a convenient and elegant method of connecting legacy analogue and digital audio equipment to the Dante AoIP audio network. What’s the difference between these units and others? The audio quality. We’re using A/D and D/A circuitry that provides analogue performance that’s 10 times better than similar competing products, offering >120dB of dynamic range.
RAVENNA/AES67 Audio over IP Products

Sonifex joined the RAVENNA group in 2012 and the AVN (Audio/Video/Network) product range is the result of our R&D in the area of audio over IP. If a Sonifex product starts with the letters AVN then it's part of the family of products which can send audio to each other over an IP network (AoIP). IEEE1588 PTP Grandmaster Clock with GPS ReceiverThe AVN-GMCS is a PTPv2 grandmaster clock for use with AoIP applications. IEEE1588-2008 PTPv2 (precision time protocol) is used to synchronise all the nodes within a network. To achieve this one of the nodes must become the master clock and distribute time packets to the others. The AVN-GMCS is designed to perform this role simply and accurately, enabling sub micro second synchronisation between all nodes.

AVN-PXH12 2 x 12 Channel Mix Monitor, AoIP PortalIn the new world of AoIP, imagine the situation where every audio network has hundreds of inputs from multiple sources streaming to multiple destinations. How can you check and monitor so many AoIP audio sources easily? The AVN-PXH12 is a world first, it can simply and effectively simultaneously monitor and mix up to 24 AES67 AoIP sources in a compact 1U rack to a speaker/headphone combination in a quick and intuitive way. Any AES67 audio channels on your network can be assigned to input channels on the unit and mixed down to analogue outputs, a headphone output and built-in speaker.
Multi-Channel Audio Mix Engine Interfaces Using AES67 AoIP - the AVN Portals
The heart of each portal is the web-enabled mix engine. Any physical input and AES67 stream input can be mixed or routed to any physical output or AES67 stream output, with gain alteration at the input, the mix point or the output. Up to 16 x AES67 input channels and 64 x AES67 output channels can be created in each portal, supporting the full range of AES67 packet times and channel counts. With this flexibility, the portals become advanced problem-solving boxes, allowing them to be used for any applications where monitoring of inputs and outputs, and mixing of signals is required. In addition, supporting native AES67, multiple stream outputs can be provided and this is combined with remote handling via GPIO, VGPIO, SNMP and Ember+ support. Example applications include:
Each of the portals can be ordered either with the input/output metering displays (D version) or without and there are two options for rear panel connectivity - with XLR/RJ45 connectors or terminal block (T version) connectors. AVN Portal Features:
