European Solidarity Center

The Challenge:

The new European Solidarity Center in Gdansk, Poland needed an audio solution for its main hall. The Center wanted to implement a multipurpose solution with the ability to transmit microphone signals at conferences and seminars, and a digital system that could play multimedia content and background music.

The Solution:

Working with ESS Audio, the team designed a HARMAN-based audio solution. Since cinema is hosted in the hall, a cinema surround sound system was installed, featuring JBL loudspeakers and subwoofers driven by Crown DSi amplifiers.

Sound reinforcement comprises JBL VerTec® loudspeakers with a Soundcraft digital mixing console. The BSS Soundweb London BLU system boosts digital signage, and AKG microphones adjust the sound volume in every multimedia setup.

The Impact:

“The decision for every component chosen was based on its performance guidelines. The systems chosen by us from the HARMAN catalog have been designed to meet all customer requirements.” – Witold Karalow, ESS Audio
