Concert Systems
Professional sound reinforcement is mission critical, with little room for compromise. Performing artists demand the best. Audiences demand the best. Most importantly, you demand the best.
That's where QSC enters the picture, with systems and factory support that truly exceed expectations, no matter how demanding and without compromises.
Earning Confidence
|
Live audio is not for the faint of heart. There are no second takes or second chances - it has to be right the first time. Real success lies in navigating the unique intersection of the creative and the technical. All of the while, you've got a business to run.
QSC is your partner in meeting each of these distinct challenges. It starts with carefully conceiving and engineering professional audio systems with the bigger picture - the total show - always in mind. |
|
These systems must be transportation friendly, quick to set up and strike and easy to integrate. They must be adaptable and reliable. They must reproduce studio reference sound quality - show after show, no exceptions. Most importantly, every system must be backed with unmatched support at both product applications and system design levels - at all hours of the day, everyday. There's one chance to get it right while meeting so many challenges. QSC makes sure you won't go it alone.

"When I put them up for Bocelli at Lake Las Vegas, the arrays looked small, but I wasn't worried about it - I knew the power, performance and sonic quality would be there. It was amazing, I had about 50 people come up to me and ask 'what is that PA?' They couldn't believe all that sound was coming out of those small boxes. Behind the scenes, the production people, the lighting people, the band, staff, management, everyone - WideLines were a home run for them too, no question."
