Brit Row's Outline ‘Butterflies' amplify the biggest rock event ever held at the New Wembley Stadium

London ( UK ) , June 6-7 2008 - 160,000 tickets sold in just two hours, months before the show. These are the figures of the Foo Fighters concert staged on June 6 th and 7 th at Wembley Stadium, one of the world's most famous venues and a “shrine” for music and soccer fans, as well as a location for other high profile events.

Wembley was a historical location for Foo Fighters . “This is a concert we'll talk about for the next twenty years”, said the group's leader Dave Grohl on-stage on Saturday 7 th June. In fact, in that precise moment, his band was joined by two members of Led Zeppelin - guitarist Jimmy Page and bass player John Paul Jones - who played an unique encore with them. Along with Foo Fighters, the pair performed “ Rock and Roll ” and “ Ramble on ”, hits from the band renowned for “ Stairway to heaven ”, enthralling the crowd.

For the sound reinforcement at the largest rock event ever staged at the new Wembley stadium (as the show was described) the organizers called in Britannia Row Productions , the legendary London rental company with a considerable stock of Butterfly systems manufactured by Outline of Brescia ( Italy ) .

Sound coverage of the stadium was mainly entrusted to 148 Outline Butterfly CDH 483 Hi-Packs, backed up by 72 Outline Subtech 218 subwoofers; powered as always by Outline T9 power amplifiers (2 x 4800W in a single rack unit and weighing in at just 12 kilos).

The audio technicians in charge - system engineer Davide Lombardi and Bryan Worthen (FOH) - installed and fine-tuned fourteen clusters comprising various quantities of Butterfly CDH 483 Hi-Packs, for a total of 148 systems, and thirty two EV X-Line systems; the bottom end was covered by flying sixteen Outline Subtech 218 and twenty four EV X-Line Subs. The remaining forty eight Outline Subtech 218 were ground-installed along the stage. The systems used for short-throw front-fill coverage were Outline DVS 15 and L-Acoustics ARCS.

Regarding the Outline line arrays used for Foo Fighters' show, System Engineer Davide Lombardi commented: "Butterfly is considered one of the best line arrays in this sector and is used regularly on the occasion of key events. I'm pleased to use it every time, as are all those at Brit Row."
