Ullevaal Stadium in Oslo, home ground of the Norway national football team and site of the Norwegian Cup Final, installed an L-Acoustics A series PA system in February.
Scandec Systems, L-Acoustics certified provider distributor for Norway, installed the stadium’s previous PA system in 1998. Planning for the February upgrade was kicked off by Scandec product manager John Idar Bakke in 2018.
When the official tender was released last year rental company Spectre, installation specialist Assemblin and Scandec, teamed up to present the L-Acoustics sound system design and was selected to deliver the project.
Bakke said: “We knew that L-Acoustics A Series would be the perfect match for this venue and provide ultimate coverage over the entire seating area. The A15i Focus and A15i Wide offer dispersions that are exactly what we needed at Ullevaal, and we were thrilled to be chosen and could bring our system design to life.”
The system consists of a total of 24 main hangs with 111 A15i Wide / Focus cabinets. The hangs are equally distributed throughout the venue, with six hangs per stadium side. Most of these consist of one A15i Focus, three A15i Wide, with one additional A15i Focus, from top to bottom. There are also six other hangs – four of these in the stadium swing. These vary from two to four A series per hang, depending on the different demands of coverage. In addition, four X12 cabinets are deployed as fills in the stadium’s media zone. A final two hangs cover sections in front of the media area, consisting of three A15i Wide atop one A15i Focus.
Bakke explained: “The system is driven by a total of 30 LA4X amplified controllers, using one channel per cabinet, which gives us great control. Additionally, Panflex technology helps ensure even coverage and great SPL distribution.”
L-Acoustics LS10 switches distribute AVB via fibre around the stadium, with Biamp Tesira server DSPs handling the audio distribution via AVB and Dante. “The DSPs also handle the delay and EQ for all fill zones,” added Bakke.
