The newly-built Ansan Evergreen Gymnasium in South Korea boasts a state-of-the-art sound system.

Used as a training venue for the recent the XVII Asian Games, and also used for the event’s volleyball and kabaddi competition up to the quarter final stages, the multipurpose arena is home to the Ansan volleyball team and will aso host other sporting events as well as music and cultural events.

Audio company Daikyung Vascom provided the sound system, which features a Renkus-Heinz PN102 line array system.

Explaining the arena’s sound innovationsf Daikyung Vascom’s RPS Business Division Manager Yang-Su Yun advises “the local council based at Ansan City Hall wanted the building to function as both a sporting venue and a concert hall, and hence they needed a very good, high-performance speaker system.

“Other strict criteria were sound quality and functionality, both of which were extremely important factors in choosing the Renkus-Heinz system.”

Yang added that having previously installed a system at the Ansan City Hall, Daikyung Vascom had a good working relationship with the Council, adding “they are familiar with our work, and they really appreciate the after sales service we provide.”

The main system in the hall comprises 32 PN102LAR array loudspeakers, configured as four arrays of eight cabinets each, 90 degrees apart. The arrays are positioned on each corner of a centrally-flown block which houses four large screens, so that spectators on all four sides of the hall have a close up view of the action. Additional fills are provided by four PN121-series two-way cabinets, as well as five ST4 three-way systems and a pair of CFX151 boxes. Four DR18-2 and two PN112SUB subwoofers provide low frequency reinforcement.

Daikyung Vascom Chief Executive Patrick Han added “the PN102 line arrays were selected for their accurate and even coverage pattern, providing consistent coverage to every seat in the hall. RHAON (Renkus-Heinz Audio Operations Network) control was another important factor in selecting the system, enabling networked DSP control over the entire system.”

Flexibility was the keyword when it came to designing the space, which will be hosting a wide variety of events. Permanent seats are available in the upper part of the hall, while bleacher-style seating along the hall’s two longer walls is retractable and can be folded back to the walls to accommodate more people.

A stage can be constructed at the far end of the hall for large concerts and, when being used in this configuration, temporary seating can be set up on the floor of the gymnasium, and a total of around 3,000 people can be accommodated.

The system design was carried out by Daikyung Vascom’s sales team, together with local systems integration specialist Sinwoo.

Working closely with Daikyung Vascom, Sinwoo’s Byung-Sun Ahn designed a system that would be optimal for the space. The team used EASE acoustic prediction software to map the room and define its sound qualities.

Ahn concluded “the actual performance of the speakers was very close to what we’d predicted with EASE (and) I’m very satisfied with the system.

“I also really appreciated being able to use RHAON to tune the system, especially the mid frequencies.”
