ELKHART, Indiana â€“ Powering audio in a major live sound application, PA Plus provided live sound reinforcement for â€œHeavenâ€™s Rehearsal,â€? a multi-denominational musical event that featured a house band, full orchestra and five-hundred member choir. The event took place on November 1, at the Rogers Centre in Toronto, Canada.
PA Plus utilized 80 Crown I-Tech amplifiers to power the large format JBL VerTecÂ® line array. â€œIn order to maintain both group and independent control over all the arrays, we chose to use the Crown I-Tech amplifiers along with HiQnetâ„¢ System Architectâ„¢ software to provide all the required processing,â€? stated Mark Radu, Systems Engineer of PA Plus. â€œWe turned the basic 30,000 seat system within System Architect and stored it as a preset. As we added array sections to attain coverage up to the full 55,000-seat capacity, the system was re-tuned and saved as a preset. The Crown I-Tech amplifiers and System Architect gave us all the processing power and flexibility we needed.â€?
The Rogers Centre proved to be an extremely acoustically challenging venue, due to its massive amount of concrete and glass with a retractable steel dome roof that extends 325ft above the field. Additionally, a large portion of ticket sales were sold during the day of the event, therefore there was no accurate way to predict what areas of the stadium would need sound coverage.
â€œThe system design worked as planned and we were able to focus acoustic energy only where it needed and minimize spill,â€? added Radu. â€œJohn Lacina, our senior engineer, did a great job with the FOH mix and was really able to make the system shine in such an acoustically demanding environment. Overall, considering all the challenges involved, I think everyone was pleasantly surprised with the final result.â€?
