The two new outside broadcast vehicles will feature Lawo's mc²36 audio consoles and A__madi4 audio-to-IP interfaces

Doha-based Qatar TV has added two new trucks to its OB vehicle capabilities, bringing its total complement of OB trucks to four. The two new OB trucks are being outfitted by systems integrator Sony Professional Solutions MEA.

The OB trucks will feature infrastructure from German audio and networking company Lawo. Each will contain Lawo's 24-fader mc²36 audio console plus external and fixed installed DALLIS I/O stageboxes, an A__madi4 audio-to-IP interface, and one V__pro8 video processor and router. Overall control of the OB van equipment will be performed via a Lawo VSM (Virtual Studio Manager). 

VSM Virtual Studio Manager is designed to manage production workflows, assuming control from the physical production hardware while providing a transition from baseband to IP. VSM supports control protocols used by major brands and models of video and audio routers, video and audio mixers, intercoms, UMDs and multiviewers, glue equipment, and other third-party devices.

Lawo’s mc²36 compact audio mixing desk features a DSP micro-core with internal 512x512 port audio matrix, and integrated I/O. It is natively equipped with RAVENNA/AES67 technology, and so can integrate into IP infrastructures. 

Qatar TV is using the V__pro8 mainly for audio embedding and de-embedding, and for format conversion and colour correction. The V__pro8 combines video and audio features in one tool.

The A__madi4 high-quality audio-to-IP interface is designed for the transport of analogue and digital audio signals via IP network environments, and for establishing IP-based audio networks. Based on RAVENNA technology, all Lawo A__line devices are also compatible with the AES67 audio-over-IP interoperability standard, and come with VisCon__navigator software for simple set-up of audio and video streams in IP networks. Beside four MADI interfaces, the Lawo A__madi4 also provides two RAVENNA / AES67 Ethernet ports and eight GPIOs.

Lawo has featured in other installations at Qatar TV, including in the broadcaster's two older OB vans, which contain Lawo mc²56 consoles and VSM, and Qatar's Doha broadcast centre which opened 2012. The broadcast centre features a master control room (MCR), central apparatus rtoom (CAR), edit studios, 450 square metre news studio, as well as a 1,013 square metre production studio.

The Lawo solutions provided for the studio complex include three networked mc²56 audio production consoles, redundant Nova73 HD central router and VSM for the overall control.
