LKAB (Luossavaara-Kiirunavaara Aktiebolag) is the world’s technical leader in supplying iron ore pellets, acquired from underground mining, to the global steel industry. The company’s new research centre in Koskullskulle, Sweden, features a visitor centre that welcomes guests to the Malmberget mine. Electrosonic was tasked by LKAB consultant WSP with designing and engineering the audio-visual facilities at the visitor centre, including its showpiece video wall comprised of 192 video tiles.

The video wall dominates the flexible main presentation space, which can seat 120 people. The wall is arranged in a 16x12 configuration for an image size of 6.5 x 3.7 meters (21.4 x 12 feet). The display consumes minimal floor space and is bright enough to be used with full room lighting or natural light streaming through an exterior glass wall at the opposite end of the room, allowing the video wall to be visible from outside the building during the Arctic winter.

A video image processor configured for eight inputs and eight outputs feeds the video wall, ensuring that all images are displayed at their full resolution with flexibility in image placement. Permanent inputs to the display include a Blu-ray player, a dual-output computer mounted in the system rack, a digital video tuner (set top box) and facilities for connecting sources like laptops. The featured content introduces visitors to LKAB and its products and processes.

Electrosonic also supplied the presentation room with a comprehensive audio system comprised of amplifiers, loudspeakers and a digital signal processor that accepts inputs from the video sources and from five microphones deployed as needed. A four-channel infrared system accommodates the hearing impaired, and may potentially be used for simultaneous translation. Two integrated controllers provide overall system control; the user interface is a touchscreen mounted at the lectern and supplemented by a portable tablet computer.

Adjacent to the presentation room is a board room for management meetings, which Electrosonic has outfitted with basic AV facilities that can be expanded as the use of the space becomes better defined. The main display in the board room is comprised of four 55-inch LCD monitors in a 2x2 array featuring ultra narrow mullions. A Blu-ray player, set top box and two twisted pair transmitters feed a presentation switcher. A room controller with touchscreen user interface provides overall control of the display system.
