How an Electro-Voice, Dynacord PA System Achieved ‘Communication Excellence’


An extensive public address system from Electro-Voice (opens in new tab) and Dynacord (opens in new tab) has been installed at Cavatina Hall. Located in the vibrant, historic city of Bielsko-Biała, amongst the Beskidy mountains in southern Poland, the six-story building counts over 9,000 square meters of top-tier office space, a cutting-edge recording studio, a chamber music room, and a majestic 1,000-capacity concert hall. The venue itself is owned by leading Polish development company Cavatina and is the first privately owned and funded concert hall in Poland.

As a large, multiuse facility Cavatina Hall required an extensive solution to cover public address across its various areas. This needed to be flexible enough to meet the differing needs of office workers and theatergoers and led to Audio Plus, the company responsible for the coordination and co-designers of the solution, turning to the Electro-Voice and Dynacord portfolio.

The heart of this solution is electronics from Dynacord, with an MXE5 Matrix Mix Engine alongside an IPX10:8 power amplifier. IPX multichannel amplifiers are dedicated for fixed installations and offer sophisticated speaker processing. IPX also features Dynacord’s unique variable load drive (VLD) technology. For each channel, the user can determine whether Low-Z or High-Z 70V/100V loudspeakers are driven without the need for an output transformer via direct drive technology. The IPX10:8 was the perfect choice for this project due to its ability to harness this technology across eight channels.
