With three OB vans already equipped with Lawo systems, six mc²56 mixing desks installed in OBs and Studios and several VSM Control Systems, Al Kass is Lawo’s most loyal customer in Qatar. Now German system integrator Broadcast Solutions has completed the construction and commissioning of OB-10 – the latest addition to the sports channel’s road fleet.

Delivered in January 2016, the 31-camera OB-10 truck makes extensive use of Lawo equipment to serve the sports channel’s coverage of the largest events in the region.

Central to the audio setup is a 48-fader Lawo mc²56 audio mixer fitted with local I/Os and 384 DSP channels, allowing OB-10 to handle the most demanding productions. Its connectivity includes 96 AES in/outputs and two DALLIS modular stageboxes. The stageboxes provide 48 mic inputs and 16 line outputs each, plus Riedel Artist intercom interfaces.

Three Lawo V__pro8 8-channel video processing units provide the video tools necessary to support a variety of different video formats, as well as to bridge between audio and video. High-quality format conversion, color correction, and audio embedding and de-embedding make the V__pro 8 a powerful tool for the use of different standards and formats as part of an integrated broadcast setup. Being a flexible matrix system, its 8×8 video matrix and 384×384 audio matrix allow switching of any signal to any other. The V__pro8’s DOLBY E encoding/decoding option provides up to four DOLBY E en/decoders for fully compatible en-/decoding of professional quality multichannel audio, complete with Dolby E metadata handling. In combination with the unit’s DOLBY E Auto Aligner, the V__pro8 becomes the perfect transmission path gateway for multichannel productions. A modern HTML5-based GUI allows easy handling of day-to-day operation.

Lawo control technology


Working as the overall control system in the Al Kass OB-10, Lawo’s VSM Broadcast Control & Monitoring system is designed to offer unmatched workflow flexibility and faster operational preparation. VSM is an IP-based control system and interfaces to all common hardware on the market, and has access to all relevant equipment within OB-10. As a hardware-independent control system, VSM connects to third-party manufactured equipment using proprietary protocols, as well as open standards. Using this combination, VSM controls the crosspoints within the truck’s Grass Valley NVISION router and Nevion Sublime video router, with access to crosspoints, Tally and labeling of the Grass Valley multiviewer. VSM includes a sophisticated Tally logic, with red/yellow/green light and UMD control, with no need for an additional Tally system.

Interoperability with the audio equipment is even stronger, with VSM having direct access to the crosspoints of the Lawo Nova audio router, plus direct parameter control. Running on redundant servers with Master-Master logic, the system provides maximum reliability and fail-safety, as well as links to the video and audio routers via redundant connections.
