ROHM Building Systems Overview (June 2021)
A two-day walkthrough of the ROHM sound infrastructure, covering signal transmission, stage connection boxes, the COMMS room and the amplified concert set-up.
Training dates: 23 to 24 June 2021
Training overview
A second, two-day run of the Building Systems course covered the first half of the programme. The first day followed signals from the stage connection boxes through the single, multi, AES and powered loudspeaker tie lines to the COMMS room, including how the patch bay’s normal and half-normal points work. The second day covered the amplified concert set-up, from the MAT boxes and Avid Stage 64 on stage to the cockpit and monitor desks, the control room and amp room patch bays, and the loudspeaker system with its line arrays, ground stacks and cardioid subs.
- Signal transmission, analogue copper cables, stage connection boxes (SCBs), single and multi audio tie lines, AES and powered loudspeaker tie lines
