Sonifex Builds AoIP Roster With Intercom And Mix Monitor Units

UK manufacturer Sonifex has produced a variety of audio over IP (AoIP)-based equipment over the last few years but most recently has been focusing on using the technology for intercom. The company showed the latest additions to its new range of AoIP talkback systems at the NAB Show, introducing six station and 20 station versions.

Sonifex launched the AVN-TB10AR ten-button intercom last year, aiming the product at OB truck, production gallery and TV and radio studio applications. The unit features connectivity through both AoIP - in the form of AES67 - and four-wire analogue. It also offers dual 1Gb LAN ports and a 1Gb SFP fibre slot for installation into bigger networks.

The new models fill in the markets above and below the AVN-TB10AR. The six-button AVN-TB6 is designed for smaller installations or those with reduced comms requirements. It is a standalone unit but can be rack-mounted using the AVN-TB6RK plates. There is also a desktop version, the AVN-TB6D, which has a smaller footprint. Both have inputs for microphones and headsets, loudspeaker output and mic mute capability.

The larger, 20-button intercom is also available as two models. The AVN-TB20AR is the rack-mount version, while the AVN-TB10AD is the desktop option. Both have features seen on the AVN-TB6 but include 20 illuminated key-cap talk buttons, in addition to buttons for Listen and Page. A function specific to this unit is the Phone button, allowing remote dialling and control of telephone hybrids located elsewhere. There is also a GPIO (general-purpose input/output) key to trigger remote operation.

Since IBC 2017, Sonifex has launched a new range of mix engine units for monitoring audio feeds in a wide variety of formats. The AVN Portal series comprises the AVN-PA8, AVN-PD8 and the AVN-PM8, all of which feature inputs and outputs on D-type sockets. The AVN-PA8 features eight stereo analogue line ins and outs, with a further 16 AoIP streams coming from AES67 sources. It is also able to output another 16 AES67 feeds and is able to stream different AoIP standards, including RAVENNA and AES67-enabled Dante (through the SAP discovery service), as well as the AES67-interoperability standard itself.

The AVN-PD8 has eight stereo AES3 digital line I/Os and is also able to stream 16 AES67 signals. The AVN-PM8 offers eight mic/line inputs and eight stereo line outputs. All three units come in two versions: the D type, as in AVN-PA8D, and the T type (AVN-PA8T). The D version has two front panel TFT meters for inputs and outputs, with additional phase metering for each stereo channel. The T models have rear panel terminal block connections for all physical inputs and outputs.

Also new for NAB 2018 was the AVN-PXH12 12x2-channel mix monitor unit. This is able to monitor and mix a total of 24 AES67 AoIP sources in a 1U rack, with monitoring on either loudspeaker or headphones. Designed for use in production galleries, OB trucks and engineering apparatus rooms, the unit has picked up several awards since being seen at IBC 2017.

Users can select the 24 audio sources from four discrete stereo analogue audio inputs or any RAVENNA, AES67 or AES67-enabled Dante streams that are connected to the unit. Stereo signals are routed to 12 control channels on the front panel, each of which having a 'Normal' and 'Alternate' input selection. Each channel has a further three buttons, one each for input selection, channel muting and selecting the output monitoring setup (left ear, right ear or stereo).

Sonifex has been working with RAVENNA and AES67 but recently signed up to the Dante licensing programme. Managing director Marcus Brooke commented that new Dante-equipped products would be introduced around February next year.
