Norway - Ullevaal Stadium in Oslo was instigated by the Lyn Oslo football club in 1926, and it is currently the home ground of the Norway national football team. It is also the site of the Norwegian Cup Final, when thousands of fans descend on the stadium. With the previous PA system having served the stadium well for 24 years, this year marks the start of a new acoustical era for Ullevaal Stadium with the installation of the L-Acoustics A Series system.
L-Acoustics certified provider distributor for Norway, Scandec Systems AS has been working with Ullevaal Stadium since the early eighties, having designed and delivered the previous PA system back in 1998. Knowing that the time for an upgrade was approaching, Scandec’s product manager John Idar Bakke had already started the design of a new system back in 2018.
When the official tender was released last year, three companies, Spectre, Assemblin and Scandec, teamed up to be fully prepared with a new, future-proof L-Acoustics sound system design, which they presented to Ullevaal Stadium. Spectre is a Norwegian rental company and has been responsible for management of the stadium’s sound for several years, whilst Nordic end-to-end installation and service partner, Assemblin, would be responsible for the installation of the final L-Acoustics system. The design was met with great enthusiasm and was ultimately chosen as the winning bid.
“We knew that L-Acoustics A Series would be the perfect match for this venue and provide ultimate coverage over the entire seating area,” says Scandec’s John Idar Bakke. “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 a total number of 111 A15i Wide / Focus cabinets. The hangs are equally distributed throughout the venue, with 6 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.
“The system is driven by a total of 30 LA4X amplified controllers, using one channel per cabinet, which gives us great control,” explains Bakke. “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,” adds Bakke.
