Case Study
Sydney Opera House
The iconic building of the Sydney Opera House has five theatres: Concert Hall, Opera Theatre, Drama Theatre, Music Room and Studio Theatre. Rooms designed and built with the highest technical and architectural rigour.
In keeping with this technical rigour, Pinanson distribution equipment is used for the microphone signals in the opera theatre.
The request for custom equipment made by the Director of Audiovisuals at the Sydney Opera House consisted of:
REF.: PTRS2628
A microphone signal distributor with 1 isolated output (Recording) and 2 direct outputs (FOH and monitors), for 48 channels. Through LK connectors. Signal patching module using XLR connectors and AR box format to install in a 19″ rack.

REF.: PTRS0197
A microphone signal distributor with 1 direct output (FOH) and 2 isolated outputs (recording and monitors) for 48 channels. Through EDAC connectors.
The wiring needed to connect this equipment was also supplied.

In this way, up to 48 microphone channels are distributed in the room from the stage to the monitor console and to the recording console (through 1 or 2 isolated outputs per transformer). All this with the advantage of being a product designed and manufactured to measure for our client.
In addition to outputs isolated by means of a transformer, the equipment has an individual Ground Lift switch for each channel, so that, if the connected equipment has a poor ground connection or battery-powered equipment is used (which can cause ground loops and audible noise), pressing the Ground Lift button may fix the noise.
