Sound Control Room for OB8
Media Mobil GmbH (MMG) from Leipzig, jointly owned by DREFA (51 percent) and Studio Berlin (49 percent), commissioned the Weiterstadt-based company, Thomson Systems Germany GmbH, to supply the new HD outside broadcast truck, OB8, which has 24 TV cameras. As subcontractor, Studio Hamburg Media Consult International (MCI) GmbH was commissioned to plan and install the audio equipment and intercom system.
The central component of the sound control room is the fully extended Lawo mc²66 digital mixing console with 48 faders. The Lawo core has 192 AES inputs / outputs, and four DALLIS frames provide a further 256 analogue interfaces. The intercom system with an 128-port and a 32-port matrix were provided by MMG. Communication is ensured by 56 digital and 40 analogue interfaces. It was planned to use a Motorola system for wireless communication and an Alcatel telephone system for additional internal and external communication.
A Ghielmetti patchbay with a total of 1,280 patch points was added to the digital audio routing switchers. The 5.1 audio system incorporate Geithain speakers RL903 and 906. Further components include two Lexicon effects processors (480L and 300L), tc electronic M6000 and DB8 as well as an event driver system. It was important that the internal routing of the audio signals should conform to the AES (Audio Engineering Society) standard, with analogue signals only being used as an interface to the audio systems and to the external periphery.
There is a further small sound control room in the editing area, which can be used in the event of a breakdown. Initially, OB6 from Studio Berlin Adlershof served as a model for this OB truck. However, at a later stage of the planning, it was decided to utilise the space differently. Moreover, the contract also included planning the audio / video equipment for the equipment vehicle. Plans included four VTRs, an 8×8 HD routing switcher, audio-video monitoring units and a post-processing section.
Detailed planning of the vehicle went on until September, assembly began at Thomson in Weiterstadt in October 2008. The outside broadcast truck was handed over to the customer on 12 February 2009.
