February 2010: Basel Scala Hall - Stoll Custom Line Array in reliable use for ten years

February 2010 – Ten years ago Stoll Audio was charged with the installation of a custom-made line array for the Scala hall in Basel. In this location with its 390 seats up to five events take place every week. Apart from various dance, ballet and theatre performances the hall is also used for company presentations, political speeches and concerts. Each of the two permanently installed loudspeaker columns is 3920 mm high, 204 mm wide and 152 mm deep. The loudspeakers were designed to deliver an even sound dispersion, a very good voice intelligibility as well as a broadband, neutral sounding music reproduction.

In 2000 Stoll Audio was in charge of installing a tailor-made line array in the Scala hall in Basel. The hall has 390 seats, arranged in ascending tiers and a stage which is 14 metres wide and 9 metres deep. Up to five events are held every week in this location. Apart from various dance, ballet and theatre performances the hall is also used for company presentations, political speeches and concerts. Tommy Otte, the technical director at the Basel Scala since 2002: “We are a professional stage in the cultural sphere. The technical infrastructure must be adapted to what’s happening on stage, because professionals want to work with professional equipment.“

The two permanently installed loudspeaker columns are 3920 mm high, 204 mm wide and 152 mm deep. They consist of five vertically stacked elements each with six low-mid woofer chassis and 14 HF drivers, working together as line arrays. The bass range is complemented by two B-118 subwoofers located in nishes under the stage. The system is driven by Lab.gruppen controllers and power amplifiers.

The loudspeakers were designed to deliver a sound dispersion of +/- 3 dB on more than 90% of the seats, a very high voice intelligibility as well as a broadband, neutral and preferably uncoloured music reproduction. Not only the acoustical parameters, but also the integration into the architecture of the hall, which was built following anthroposophical guidelines, were a crucial factor for the customers. “I’m definitely happy with sound rendition and coverage“, says Tommy Otte. “But what thrills me most about the installed sound system, is its reliability. We didn’t have a single system failure in all those years. We need to depend 100% on our gear, and the installed system from Stoll Audio offers this dependability“.
