By PSW Staff • July 16, 2018 Classic Open Air Festival in Berlin ( Credit and Copyright: DAVIDS") The Classic Open Air Festival at the Gendarmenmarkt in Berlin has been a good tradition for 27 years. But making it happen presents a new challenge every year. Classical music in the open air is demanding in terms of acoustics and requires a special sound reinforcement system. The critical audience is accustomed to perfect concert hall sound. This year, for the first time Berlin-based manufacturer Stage Tec also contributed to ensuring the audience could enjoy the five festival concert evenings. A NEXUS system was used as the front of house matrix and routed the output signals from two mixing consoles to the PA system. The gain-delay matrix of the DSP board performed signal processing within the NEXUS system. The level delay matrix employed enables simultaneous distribution of input signals to multiple outputs. Here, gain and delay could be set individually for each input per output bus. The outputs of the gain-delay matrix were used to control different sound reinforcement zones at the Gendarmenmarkt and the individual mixes were output to the sound reinforcement system via dynamics units (limiters) over Dante. This achieved a uniform level across the wide Gendarmenmarkt square, enabling the audience to experience the five concerts with the best sound. “The modularity, system stability and mechanical construction of the Base Device convinced me. When operating via the Nexus GUI, we noticed a positive feature. Several routings could be prepared in advance,” explains Ben Spindler, freelance sound reinforcement specialist. “Afterwards, they could be switched without clicks. Using states saved previously, I could quickly switch between two scenarios (zone and stereo sound).” Event equipment and service provider TSE AG (Technik und Service für Events AG) used NEXUS as the front of house matrix on this project. NEXUS was able to demonstrate that its variety of analog and digital interfaces, DSP functionality, and low-latency networking make it the go-to solution for all types of sound reinforcement tasks. This year, the Classic Open Air Festival took place from July 5th – 9th.
