Expansion on the cards at Wohler

Wohler Technologies’ iVAM1-1 16-channel audio-video monitor has received an upgrade in the form of new AoIP and analogue plug-in expansion cards. When upgrading the iVAM1-1 to monitor Dante, Ravenna or 2110-30 signals, the AoIP card is included. Customers can specify either Dante or Ravenna and both options are capable of monitoring 2110-30 signals. The card also includes primary and secondary RJ45 Ethernet ports and a 1GB network SFP cage capable of monitoring AoIP input streams via fibre input. A TOSLINK (SPDIF) input connector, often used to monitor the output of set-top boxes, is included for convenience. For users requiring additional analogue inputs, the new analogue option card offers a further eight balanced inputs and outputs on DB-25 connectors as well as a TOSLINK (SPDIF) connector.

A free firmware update has also been released by Wohler for its flagship iAM-12G-SDI when purchased with the Dolby Atmos option. Two new screens have been added to the interface to help users visualise the location of each audio bed or dynamic channel for both actual and dynamic channels. The first screen shows the listening room with a 3D front view, with a representation of the video programme screen location shown in the centre as a white rectangle. The various objects are shown as named channels for the audio bed objects or as numbered channels for the dynamic objects.

Dynamic objects move around through the 3D screen as they move in the programme material, with the objects appearing according to what is present in the Dolby Atmos bitstream. A maximum number of 16 objects can be displayed simultaneously. The second screen shows the listening room from a 3D top-down view. This display gives a representation of the video programme screen location, shown in the centre top (front wall) as a white rectangle. Also shown are audio bed objects, which are in fixed positions as speakers in the listening room. Either dynamic channel objects or audio bed objects can be shown in the Dolby Atmos 3D Room Visualiser.

Furthermore, a Metadata screen is also included, providing three sets of data: traditional Dolby metadata, loudness data and presentation data, which provides X-Y-Z coordinates for the position of objects in the 3D Room Visualiser.
