Zhengzhou Art Palace Center Renews Its Sound System with DAS Audio Equipment

The sound of this cultural space in China is based on two groups, each with six Aero 20A line array as main system, with the DASaim optimization tool, and two LX-118A subwoofers flown in each cluster, all controlled and monitored by DASnet.

Located in the center of the Chinese city of Zhengzhou, the cultural space Art Palace is a center of intense activity in this sense, which houses two important theatres, with capacity of 1.338 and 186 seats, respectively, in which an important reform has been carried out to turn this enclosure into a versatile environment for different uses.

On the renovation of Zhengzhou Art Palace, which even includes a platform lift on stage, A fundamental element has been the new sound system, whose project has been the responsibility of the company Chao Ganguan, formed thanks to the union between DAS Audio and Fluge Audiovisuals in the Chinese market.

Among other requirements, The new sound system had to be powerful and adaptable enough to meet all the needs of this versatile space., From ballet performances and dance performances to opera and symphonies by leading national and international groups.

The DAS Audio system installed for the sound of the enclosure is structured in two clusters formed by six Aero 20A line array as the main system, with the integrated DASaim optimization tool (thus avoiding the installation of boxes in the back), along with two LX-118A subwoofers flown in each cluster, in a left/right jam on both sides of the stage for uniform coverage of the main BP, all controlled and monitored by the DASnet remote control system.

As they point out from this company, "Normally, Subwoofers stack on the floor for powerful low frequency. Taking into account the situation of the enclosure, This will increase the frequency too low for the front seating area., but it will produce infrequency in the upper seats. So, Chao GanGuan Technical Team, which is the subsidiary of DAS in China, recommended flying the subwoofers to achieve uniform coverage".

To this is added the installation of four Artec-526 speakers, located at the front of the stage for spectators at the front, and four Vantec-12A as stage monitors, also controlled with DSP4080 audio management system and DASnet.

One of the challenges of this project is that the renovation in the interior decoration had not been carried out., so there was no possibility of rewiring, with the difficulty of adding speakers for filler.

"The DASaim digital address solution, which is integrated within Aero 20A, that was recommended can modify the interaction of the cabinet and, therefore, the radiation pattern of the array with the frequency. It is possible in this way to redirect energy where it is needed.", explain those responsible.

DASnet Rack remote control system used with Aero-20A active speaker array integrates signal processing, Control, distribution (also that of energy) in one unit. "Thanks to this," they point out, ", The sound engineer can monitor the working status of each speaker from the control room during performance, make the necessary adjustments in time for easy adaptation of the operating system".
