China - Hangzhou Chuangda Stage Facilities, the D.A.S. Audio dealer in Eastern China, has coordinated the installation of new sound systems at two popular Chinese clubs in late 2010. With both projects, Jiang Chao, the company's general manager, and Xiao Zhao, their technical representative, determined that D.A.S. active (self-powered) systems were an appropriate choice.

At owner Ping Ge's IN-Bar in Taizhou, Zhejian, 24 D.A.S. Audio Avant 15A powered, two-way, compact full-range loudspeakers were deployed. A combination of six LX-218A powered, high performance subwoofers - three enclosures ground stacked in a centre mono sub configuration and another three units placed as delay subs - deliver low frequency support. An additional five Avant 118A powered horn-bass subwoofers complete the setup. A D.A.S. Audio DSP-2060 processor handles time alignment and limiter duties.

Xiao Zhao comments, "The Avant 15A includes a rotatable horn that enables one to control the unit's coverage. By rotating the horn, we were able to get the same coverage by flying the speakers horizontally - therefore, not compromising the view of the customers. The LX-218A and Avant-118As handle low frequency reproduction beautifully. Having applied time-alignment parameters via the DSP-2060, these subs complement one another very nicely."

At the HJFB Bar in Zhoushan, Zhejian, owner Fang Hua elected to have a similar setup installed. For this project, eight D.A.S. Audio Aero 12A loudspeaker enclosures - flown four elements per side in a left-right configuration - serve as the house mains. These loudspeakers are augmented by 12 Avant 15A loudspeakers, which are placed as delay-fills. For low frequency support, five LX-218A subwoofers are augmented by an additional four Avant 118A sub bass enclosures. A D.A.S. Audio DSP-4080 processor handles time-alignment and limiter tasks for different groups of speakers and zones.

"With the trend of bars in China having singing performances every night - together with their selection of electronic music - we're dealing with a system that is very versatile," says Xiao Zhao. "The installation had to be done in a way that the singers do not encounter feedback when they walk from one performance area to the next. The challenge was to keep everything sounding as natural as possible without the loss of clarity."

Eduardo Lopez, D.A.S. Audio Asia's business operations manager, reflects on the company's recent growth in the region. "With D.A.S. Audio's vast selection of products to address a wide range of sound reinforcement applications, and China's growing interest in active speaker systems, I'm confident there will be many more opportunities for us to expand this emerging market."
