"The main requirement was that sound could be distributed from a central source to each of the four zones, but with local control in each," explained Joachim Bergling, installation specialist at the project's audio contractor, PADAB. "An early decision was taken to use a Yamaha EtherSound system for distributing the sound, because of the flexibility, audio quality and reliability that it delivers."
Central control and audio distribution is handled by a Yamaha DME24N digital mix engine with MY16-ES64 EtherSound card. Four DME Satellite DME4io-ES units have been installed - one at the FOH position in the main arena, with one each (plus CP4SW remote control) in the sports bar, restaurant and main entrance.
During a sports event, the sound operator uses a mobile rack with an eight-channel mixer. Sound sources such as an announcer's microphone and background music source are fed from the mixer to the DME4io-ES, which sends the signal via EtherSound to the DME24N, distributing it to the other areas as required.
Yamaha loudspeakers and amplifiers also form an important part of the Stadium Arena audio installation. Ten Installation Series IF2115 full-range loudspeakers with two IF2112s for downfill, driven by XP7000 and XP5000 amplifiers, have been provided in the main arena, while the other spaces feature a blend of XP3500, P3500S and P5000S amplifiers.
