ArrayProcessing controls OppiKoppi

SOUTH AFRICA: Blue Array Productions supplied audio equipment on all but one of the seven stages at OppiKoppi 2015. The Pretoria-based rental company opted to use d&b Audiotechnik’s ArrayProcessing software to control the audio on the Main Stage.

Blue Array equipped The James Phillips Stage and the Skellum Stage with d&b Q-Series systems, while the Bruilof Stage was kitted out with V-Series L/R. On the Main Stage it was J-Series, comprising J8s and J12s supplemented by J‑Subs which were both ground stacked and flown behind the main arrays.

‘Not having used ArrayProcessing before, I was intrigued to experience both the process and the result,’ said Blue Array MD Kobus van Rensburg. ‘We designed the system in the d&b ArrayCalc software to give us the best front to back coverage as we would normally do. Then we applied the ArrayProcessing algorithm to the main array to give us a 2dB drop in SPL from front to back, which was over 80m away. This whole process only took about five minutes from design to implementing and loading the parameters into the amplifiers.

‘It is no exaggeration to say the result was absolutely astounding,’ he continued. ‘The front to back coverage was smooth and consistent without any tonality changes at all, just that slight defined 2dB drop in SPL as you moved towards the back. I’ve not experienced such even tonality from any PA system ever before. We also found that there was no distortion or audible artifacts present at any volume, high or low.’

‘I had comments from one visiting engineer that he was able to mix the band much louder than usual – and he was under strict instructions to do so,’ added onsite head of audio, Marinus Visser. ‘At one point, we reached peaks of 118dB SPL A-weighted at FOH (50m away) with 10dB headroom on the whole system. The consistency and clarity meant I could really mix the show with great confidence and be assured that whatever I was doing at FOH was heard by every member of the audience – wherever they were.’

‘We received constant compliments and commendations from audience members, promoters, and other sound technicians and engineers attending the festival,’ concluded Mr van Rensburg. ‘I have to thank d&b for breathing new life into their already amazing systems which remain the easiest and most effortless PA to design, deploy, tune and mix on. These are just a few of the things that define what makes an incredible sounding show. Success every time. You can’t go wrong with that.’
