To ensure audio coverage for the audience, 20 Outline Butterfly C.D.H. 483 Hi-Packs and four Subtech 218 were flown (respectively ten and two per side), the latter for the ultra-low frequencies. Six more Butterfly C.D.H. 483 were used as ground-stacked systems.
The entire system was controlled by a Dolby Lake processor and powered by Outline's new T Nine digital power amplifiers (2 x 4800W on 2 Ohms). The FOH engineer for the event was Derrick Zeiba.
