Ambient sound equipment in the Rektorat’s halls include the JBL outdoor models Control CRV, Control 29AV i Control 25, whereas the built-in ceiling speakers found their place in the Rektorat’s offices. Due to the complexity and the size of the building, the ambient sound system is based on 100V line. A computer, an internet radio played via Sonos Connect and a CD player are all the sources of sound. Crown amplifiers, model 280MA, as well as Crown CDi 1000 were installed. Signals are sent by DBX 1261 and zone controllers DBX ZC8 which enable the full control of audio signals. The distribution of video signals to the full 42’’ HD LED screens is performed by HDMI extender and splitter.
The amphitheater represents the central technological unit. The main part of the audio system consists of digital audio matrix BSS Soundweb London BLU-160 with the wall-mounted control unit BSS BLU-6. The sources of sound (PC, Blue-Ray player and wireless microphone system) are connected to the amplifier Crown Xti 4000 and loudspeakers JBL CBT70J via these, thus enabling balanced and uniform sound coverage and excellent understanding of what the speaker is saying.
