One Systems Amplifies an Upcoming International Football Training Venue


Nashville, TN, June, 2010 - Prosound (Pty) Ltd of Johannesburg, South Africa recently installed One Systems’ CrossField Array speakers in the newly re-named, Lucas Moripe Stadium in Pretoria, South Africa, training site for the upcoming top international football tournament.

Since being renovated and brought up to the most recent stadium infrastructure regulations, stadium officials began looking into upgrading the sound system as well. After hanging on to the original sound reinforcement system that was installed in early 2000, they realized a system upgrade was desperately needed before the large upcoming summer events. The older, ‘budget – driven’ system was comprised of equipment designed mainly for speech reinforcement, which lacked the SPL capability and extended frequency response necessary for high-impact music and sound.

The outdoor stadium seats 28,900 for soccer and other athletic events, and is also used for community events like worship services, rallies and other large-scale performances. It is a prime example of a high-noise sports and convocation stadium, which requires highly-intelligible speaker systems with full-bandwidth response that can withstand years of exposure to the elements. Subsequently, when Prosound was awarded the contract to upgrade the system, they chose One Systems based on experience from previous installations and their knowledge of the product’s quality and weather proofing technology.

Due to South Africa’s extremely warm summer temperatures and often-dramatic thunderstorms, Prosound knew that weatherproofing was needed for this audio installation. “We chose the One Systems CrossField Array speaker systems, as these units provided us with an off-the-shelf solution for both the weather resistance and also provided us with the SPL and frequency response to do the job, “ says Prosound’s Head Systems Engineer Grant Scott.

Working closely with stadium officials, the main goal was to provide more full-range audio to the open seating areas in the North, East and South stands. The fact that the stadium has open seating on those particular grandstands, the only place to install speakers was on its covered West roof. Six CrossField Arrays were installed in three clusters of two on the west roof, and the stadium couldn’t sound better. “The client is really pleased with the results we achieved. The system achieved an STi (Speech Transition Index) of .072, which is really good for a solution of this type, especially over a distance of more than 120 meters (396 feet),” boasts, Scott.

One Systems President, Doug MacCallum says, “Weatherproofing, wide bandwidth, high output and pristine vocal intelligibility are what our speakers are all about. They work especially well in these high-noise, long throw situations and as always, it is exciting to be a part of such a high-profile, global venue.”
