Get Ready for The Next Level
so it’s tricky to say the least. The complexity comes in achieving the correct time alignment to cover the area without compromise. “The main arrays of Vi-Series in the north / south end zones provide all end grandstand coverage, con- sistent with the main east / west coverage. But as the end zone roof falls well short of the front rows, by as much as 30 metres, these arrays are practically horizontal in orientation though still highly curved. However, even at these distances we found that we only needed to apply about +3dB to the cabinets covering the front rows compared with those covering the closer rear and middle seats,” continued Scott.
Alongside all the arrays - each of which sits in a frame engineered by The P.A. People and are mounted on two electric chain hoists supplied and installed by Jands Electronics - Scott specifi ed 32 d&b audio- technik Ti10P loudspeakers for under balcony fi ll and a combination of 18 d&b audiotechnik Ti10L and four d&b audiotechnik Qi-10 loudspeakers for delays in the upper bowl. However, the under balcony fi ll requirements change dependent upon whether the lower seats in the East and West stands were in their retracted position or not. The moveable seating sections weigh 3,500 tonnes, are 100 metres long and retract 15 metres - one metre per minute - using 14 motors. To move the seating forward, which essential puts the audience closer to the action takes three and a half hours in total. The system is powered with 96 d&b audiotechnik D12 amplifi ers distributed evenly between the four amplifi er rooms. Signal is distributed to the amplifi er rooms over a legacy Ethernet network using Dante protocol. BSS Soundweb London BLU-326 processors in the control room collect processed audio from the Yamaha DME64 digital mixing engine fi tted with Lake DSP cards. Further BSS Soundweb London BLU-326 units are deployed in each amplifi er room to deliver AES audio to the d&b audiotech- nik D12 amplifi ers. The analogue inputs of the d&b audiotechnik D12’s are connected to the legacy analogue cable network, BSS Soundweb London BLU-BOB output frames in the control room provide the analogue signal source to the analogue network. This provides complete redundancy of the signal transport throughout the stadium. In the control room there is a Yamaha M7CL digital console to take care of the mixing requirements during events and the interface for the d&b audiotechnik R1 Remote control software. The P.A. People’s Ash Selars was in charge of networking infrastructure at the stadium. He said: “We
