October 2011: Powerful and clear - rock power for five thousand open air visitors

At the weekend of September 9 and 10 a very special metal festival took place in Hüttikon (Zurich/Switzerland). On these two days 20 bands were pleasing the total number of five thousand visitors. The Meh Suff! society devolved the overall responsibility for the event technology to the Crazy Lights AG company. They have been in charge of the festival since 2006 and this time wanted a better sound quality than in the previous years. Therefore Crazy Lights AG opted for a sound reinforcement system from Stoll’s dry hire pool. Besides two line arrays each with six Stoll CFR 2610 Convertibles and two Stoll Convertibles as near and downfills, four Stoll IL 3500 Infralowswere also put into service. The FOH (Front of House: audience zone) loudspeaker systems were driven by Lab.Gruppen PLM power amplifiers with a total output power of 70 kilowatts.

The FOH sound system totally impressed the visitors and organisers alike. “The Stoll PA system has convinced us and also made the external sound technicians rave“, says Tobias Kehrer, project designer of Crazy Lights. First the SPL requirements typically associated with metal were met hands down. The concerts were performed at the official volume level of 100 decibels Leq (long-term equivalent continuous sound level), with peak SPLs of max. 132 decibels (A-weighted) at the FOH mixing console in 30 metres distance.

But it’s not all about loudness, and so the system was able to score above all with its unique tonal quality. The punchy and yet clear sound image coming from the line arrays and fills and the ultra-deep and, owing to a minimal group delay, super precise low end were adding to a unique acoustic experience in the entire listening area. The raving reactions of the spectators proved that a focused loudspeaker know-how can create unparalleled sensual acoustical experiences.

Tobias Kehrer offered a positive summary: “The clarity and detailed reproduction of the Stoll system were still very good with the nine-piece pagan metal band Eluveitie. I was also very surprised at the plug n‘ play capability of the system. The very high sound quality and the ease of operation make a conclusive combination.“
