Engineers use L-Acoustics 3D tech to plan complex tour for Hong Kong star

A mammoth PA system providing 360° sound for one of Hong Kong’s biggest stars has been supplied by French manufacturer L-Acoustics.

Singer Jacky Cheung’s A Classic Tour, who is crowned in his home country as the ‘God of Song’, is making its way around 21 indoor and outdoor venues in China, Hong Kong, Singapore and Taiwan.

L-Acoustics’ Chinese distributor Rightway Audio Consultants created a complex audio design to meet the demands of the tour. While this potentially proved a challenge, engineers used L’Acoustics’ 3D simulation programme to figure out a set-up that could work at individual venues alongside complex stage machinery.

“We based the audio design on the predictions we had made using L-Acoustics’ Soundvision 3D acoustic simulation programme,” said Daniel Kwan, FOH engineer for the tour.

“Soundvision is an incredibly useful tool, as it meant we could easily predict how the system would react when we moved from venue to venue. This was particularly useful when selecting the position and model of the speakers and meant that we could always ensure the entire audience area was fully covered.”

The four-side stage includes a circular staircase, a rotating compass and a walled fortress, with the AV and lighting systems suspended above the stage.

For the outdoor venues and select indoor venues where weight loadings were an issue, the system was flown on a complex truss system, ground-supported by four towers (with one at each corner of the stage).

Working with monitor engineer Mike Huang, Kwan ensured that any feedback issues were reduced to a minimum and that the system was properly balanced.

“By using this system – as well as ensuring great audio quality – both load-in and -out were very fast and convenient,” said Kwan.

“We are proud to have been involved in such a successful tour. This is in no small part due to our L-Acoustics system,” he added. “I am impressed with its sonic quality and predictability. It gives me full confidence that it will provide the best solution, as always.”
