At the heart of the sophisticated audio system is a Dynacord Promatrix System, which provides safe and precise control over 84 loudspeaker zones, 28 fire alarm inputs, four digital DPC 4520 paging stations for the main exhibition hall and the control room, a CD multiplayer controlled by the DPC 4550, four different sources of background music (selectable via a DCS 409 interface control card) and 32 amplifiers, controlled by the system and with all their parameters and operating modes displayed on the DCS 420 monitor.
The system allows precision monitoring of the loudspeakers, while the DSP technology allows the prevailing conditions in all the individual halls to be monitored and accounted for. The DPM 4000 can also be employed as a system master control unit. The loudspeakers used in the complex are Electro-Voice EVI-15 Vari Intense Speakers, which combine high quality sound with considerable coverage.
