On Mon 21st May 2012 Gearhouse Broadcast Audio Engineer Peter Craig hosted 17 AES members and guests on a tour of one of their Outside Broadcast vans utilized by both the Seven Network and Fox Footy for AFL, and by a range of clients for other sporting and special events broadcasts.

The van boasts an impressive range of latest technology audio, communications, video and recording equipment, including a Lawo MC56 digital production audio console, a Reidel digital intercom system, Sony MVS8400 Production Video Switcher, Pro-Bel Cygnus router, and an array of EVS Hard Disk video recorders.

Peter gave us a thorough run-through of HD-2's capabilities.

He started outside the van - with the power inputs and UPSs, and then 'round the back to the fibre and copper connection panels.

He pointed out that all audio and comms, and most video (depending on cameras deployed) is fed to and from the van using fibre-optic cabling, with the audio and comms typically using MADI (AES10) interfaces.

Moving inside the van, Peter gave us a detailed look at audio and comms first, describing the Lawo MC56 digital console and its peripherals, and explaining its operation in a typical footy broadcast; as well as the Riedel digital intercom system, which provides selective intercom between all production staff and talent, a key element in coordinating a complex broadcast like live sport.

The tour then moved on to Production Control and the monster Sony switcher , "VT" - the video recording booth, where tape-based VTRs have been replaced by EVT hard-disk recorders; and Camera Control where several operators adjust the CCUs (Camera Control Units) to maintain correct exposure and match the pictures from up to 28 High Definition or Standard Definition cameras.

The Section would like to express appreciation to Gearhouse Broadcast, particularly Head of Operations Garth Wiencke, and Audio Engineer Peter Craig for facilitating this tour, and giving the lucky members a fascinating insight into what it takes to bring live sports to our home speakers and screens.
