Presentations at Leicester City’s King Power Stadium have been “revolutionised” by the installation of a new Electro-Voice sound system.
As part of the upgrade, Birmingham-based installer DMX Productions needed to achieve uniform coverage of the “challenging shape” of Walkers Hall, which is used for presentations and conferences. Electro-Voice’s EVC-1122-VI loudspeaker, which is said to possess a unique variable-intensity configuration that evenly covers a clearly-defined rectangular area, was selected for the task.
“The variable-intensity technology gave us exactly the right amount of gain shading to cope with the change in room height, and the uniform coverage that we set out to achieve,” DMX Productions’ SJ Grevett said.
The main solution is formed by eight white EVC-1122-VI cabinets, mounted near the ceiling of the 3.9m-high void space. These are supplemented by 16 Electro-Voice EVID 6.2 wall-mounted loudspeakers. According to the company, the high loudspeaker count further contributes to even coverage at moderate sound levels, yet ensures plenty of headroom when needed.
“SPL measurements confirmed that coverage is really even, with only two to three dB difference in level anywhere in the room,” Grevett said. “In every room configuration – end-on, or with stage either at right or left such as for the players’ awards – a presenter can roam with a radio mic, even directly underneath a loudspeaker, and there’s no risk of feedback.”
LCFC technical manager Tom Brown added: “I’m really pleased with the way the EVs cover the whole of the Walker Hall, it’s totally seamless no matter where you are in the room, and the speakers look and sound great!”
A further two spaces – a bar area and a conference room – are fitted with ZX1i loudspeakers, while a set of Evolve 50 portable column speaker systems is available for special events requiring extra-high SPL and extended bass.
