Martin Audio Supports Successful Debut Of Vortex Festival In Germany

WPS and WPC line arrays as well as SX218 subwoofers team up with DISPLAY software to deliver 12 hours of continuous coverage while meeting stringent SPL requirements.

Vortex, a new electronic music festival that recently made its debut at the EWS Arena in Göppingen, Germany, featured techno, trance and hardcore music in play continuously over 12 hours that was delivered by Martin Audio Wavefront Precision line arrays.

Because the venue is located in the center of the town, surrounded by shops and flats, the requirements with regard to noise escape were stringent. As a debut event, it was particularly important for the organizers not to provoke complaints from local residents in order to preserve the future of the event.

Jürgen Schuster from event technology specialist Skyeline Live, who provided the technical equipment for the festival, states,”There were no noise complaints and zero problems with the volume for the audience.”

Martin Audio DISPLAY software proved essential in controlling the WPS and WPC line arrays deployed. “It was a real blessing,” he explains. “I was able to calculate the entire system cleanly and deploy it accordingly. This made it possible to predict in advance exactly how the system would behave in terms of sound levels.” He adds that during the event, a colleague checked the volume on the street, enabling him to confirm: “Ambient noise from the street was louder than the sound coming from the festival, while inside the venue the sound was characterized by the evenness of distribution across the entire event area.”

To achieve this, Schuster deployed 24 Martin Audio WPC elements as the main system (12 boxes a side), with eight WPS as front and side fill. Low frequencies were pumped out through six towers of three SX218 subwoofers designed in cardioid (two front facing and a single rear facing), with a further four SX218 provided for DJ monitoring. The rig was powered by 12 Martin Audio iK42 multi-channel, process-controlled power amplifiers in three-box resolution.

Schuster attributed the success of the event to the scalable resolution of the Wavefront Precision loudspeakers and the acoustic optimization using the DISPLAY simulation software. “The combination of these two aspects made it possible to calculate the sound solution for the event so precisely that sound emissions were minimized [offsite] while still providing uncompromising sound for the 4,000 dance fans.”

In conclusion, he cites the sonic coherence across the different series and how they can be combined. “WPC and WPS are different size formats but they fit together perfectly in all technical respects—phase response and so on. With many manufacturers this provides problems as the speakers don’t fit together in terms of sound. This is certainly not an issue with Martin Audio, as the different series work wonderfully together.”
