Brett better after Pure AV, Martin Audio integration

Brett better after Pure AV, Martin Audio integration

On the coat-tails of a £5m refurbishment of Liverpool University’s Senate Drum building, a new teaching facility, complete with advanced AV infrastructure, has been opened under the new name of the Brett Building.

Pure Audio Visual were awarded the contract for the upgrade, and the challenge of providing consistent audio in an acoustically awkward cylindrical shaped building has been met by specifying Martin Audio’s DD6 Differential Dispersion technology enclosures.

The facility incorporates break-out facilities, and will be used as both a conference and exhibition space as well as for teaching. “We looked to the market for a small box solution with a controlled directivity that could be placed around the edge of the room and provide even coverage across the audience areas – and more importantly, keep that sound away from the presenter,” says Pure AV’s systems integration specialist Colin Hasted. “The DD6 fitted the brief perfectly. The differential horn technology meant that we could place the speakers so that the dispersion narrowed towards the centre of the room creating an impressively even coverage from the back row to the front.”

Hasted’s rationale was further based on the limited space and ceiling height behind the presenter which immediately suggested that a distributed system was the best option. Overhead speakers were ruled out due to the artistic ceiling centrepiece – an elaborate sunburst through which daylight from the skylight above is channelled through wooden slats.2Z9C0394large

Seven DD6 units, each individually controlled, and processed via BSS Soundweb London BLU-101 (with Acoustic Echo Cancellation), are spaced equidistant around the room; these cover the audience area with a slight graduation in level towards the back of the room. “This, as well as the exceptional acoustic treatment provided by the main contractors [Aspect Construction], gives the illusion of solid front-on coverage,” Hasted continues. “EQ usage was minimal as the DD6 provided clear and crisp voicing straight out of the box, a speaker I would thoroughly recommend for future speech applications.”

Pure AV technical director, Richard Lister, adds: “The Martin Audio DD6’s were perfect for the job,” he summarised, “and with each of the speakers receiving its own channel of amplification, fed from the DSP, the sound is fully optimised and the client is over the moon.”
