ROHM Building Systems Overview

Diego Biagioni led a four-day tour of the building’s sound infrastructure, following the signal from the stage to the amplifiers. Day 1 covered how signals travel through the building on analogue, AES and powered loudspeaker tie lines, from the stage connection boxes to the COMMS room patch bay. Day 2 looked at the set-up for an amplified concert, including the Avid Stage 64 boxes, the monitor and front of house desks, the amp room and the Galileo, Galaxy and Compass loudspeaker management. Day 3 covered non-amplified concerts in the concert shell, with the Optocore links and the gallery and proscenium loudspeakers, and Day 4 was spent reading a visiting show’s technical specification, input list and stage plan and mapping them onto ROHM’s stage areas.
