Centennial Hall is a late Victorian civic function room that doubles as a 1,600-capacity concert hall. For its long-awaited audio refurbishment, the task was to ensure "a zoned coverage of the audience area with a focus on speech intelligibility," said Wilsallen. "The system was to consist of a single-flown array with under-balcony fill and a separate bass array."
As is typical of civic buildings from this period, Centennial Hall features long narrow balconies running the length of the hall down each side. Wilsallen therefore devised a system based around six d&b audiotechnik J8 line array loudspeakers with a further three J12s below. "This configuration achieved the best compromise in coverage while avoiding unwanted reflections," he said.
The specification also features d&b E0s for balcony fills, while low-end performance can be enhanced with an array of d&b Q subwoofers when required. The system was optimised using d&b ROPE C remote control software, described by Wilsallen as "very good, very intuitive [and] easy to use."
The d&b equipment was supplied by the manufacturer's Australian representative, National Audio Systems, to installation company The PA People and its leader for this project, Brett Steele.
