tv productioncenter zürich (tpc): New HDTV OB truck with AURUS control room
The vehicle of the Swiss outside broadcast specialist tv productioncenter zürich (tpc) has been designed to provide studio facilities for major live events such as the Olympic Winter Games Torino 2006 and is fully equipped to support HDTV. The new programming demands for 5.1 with HDTV made the choice easy for tpc: They opted for a large AURUS console in the truck’s sound control room. 128 audio channels, 128 busses, and 48 fader strips on the AURUS now support even big surround sound productions. Too, the unique multichannel features of the desk recommend AURUS for this applications: Allowing to work on two or even more mixes simultaneously, e.g. one stereo version and one 5.1 mix, AURUS eliminates the need for quality-deteriorating automated downmixes or for an additional stereo mix. Thomas Neuenschwander, project engineer of tpc, says: »Equipping a truck for HDTV is a once in a lifetime investment. AURUS was our first choice, as it combines extreme reliability and perfect audio quality with quick and simple operation – no matter whether it’s a complex 5.1 production, a stereo mix or even both.«
Along with AURUS, the truck incorporates a NEXUS audio network of four base devices on board. Another three mobile base devices will be used as stage boxes on-site. The internal NEXUS provides a total of 100 AES inputs and 96 outputs, 112 line ins and 104 line outs, as well as several interfaces such as MADI and TDIF audio interfaces and GPI contacts. The moveable base devices not only offer to bring all necessary I/Os and interfaces close to the cameras, but also integrate all subscriber units of the intercom into the audio network. »Thus, no extra cabling for the communication network is required«, explains Sebastian Schmidt, engineer in charge for this project. For maximum safety, the audio network has been designed with a high degree of redundancy. Therefore, all NEXUS base devices are equipped and cabled with double optical interfaces as well as with redundant power supplies for automatic and delay-free switchover in case of power or line failure.
