d&b audiotechnik overcame historic intelligibility problems for a recent audio installation at Church House Westminster.
The project focused on the site’s Grade II-listed Assembly Hall, primarily used for conferences and meetings.
Church House AV manager Ian Locke worked with freelance sound designer and engineer Phil Wright to ensure the most appropriate units were selected throughout the cylindrical, dome-roofed venue.
“We undertook some tests with the existing system in the downstairs area, and found that for any given impulse we put into the PA we could measure ten to fifteen distinct arrivals at the measurement microphone,” explained Wright. “From an intelligibility point of view it really was a bit of a disaster, so resolving that was priority number one for the new d&b system design.”
The answer came in the form of d&b’s Y-Series, designed to suit applications as varied as houses of worship, symposiums and car expos. The installation oriented Yi7P loudspeaker cabinets house two 8” low frequency drivers and a 1.4” compression driver. At Church House, Yi7Ps are flown either side of the main stage and a pair of Yi-SUBs provide low end reinforcement.
London-based sound engineering company RG Jones was appointed to undertake the fit-out of the new system. Jeff Woodford, project engineer at RG Jones, oversaw the installation. He said: “It proceeded very smoothly indeed. We had about four people onsite doing cabling work and fitting loudspeakers at any one time. The overall improvement in sound quality is clear for everyone to hear – I would say it is about ten times better than before!”
