HOUSES OF
WORSHIP

St. Andrew’s is the oldest cathedral in Australia and with it numerous acoustic challenges, not least of which was reverberation times making clarity and evenness of coverage across the congregation a constant issue.

Further, the unusual logistics of church services involves a 360 degree presentation from the pulpit, a centre transept area where choirs and clergy require sound reinforcement and a church where the congregation could sit anywhere at any service and expect perfect sound. On top of that, priests would move through the nave on headset radio mics with open mics for question and answer sessions.

The system deployed 140 O-Line elements (distributed over 22 hangs), utilising one box resolution so each element in the array is separately amplified and processed using FIR filters. This enables the system to not only be mechanically and electronically steered but allows consistent frequency response throughout the listening area — without the lobing (impacting tonality) associated with straight columns.
