FEATURES: INSTALLATION The main system in the hall comprises 32 PN102LAR array loudspeakers, con gured as four arrays of eight cabinets each, 90-degrees apart. The arrays are positioned on each corner of a centrally- own block which houses four large screens, so that spectators on all four sides of the hall can have a close up view of the action. Additional lls are provided by four PN121-series two-way cabinets, as well as ve ST4 three-way systems and a pair of CFX151 boxes. Four DR18-2 and two PN112SUB subwoofers provide low frequency reinforcement. ‘The PN102 line arrays were selected for their accurate and even coverage pattern, providing consistent coverage to every seat in the hall,’ says Daikyung Vascom’s CEO Patrick Han. ‘Rhaon (Renkus- from 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 de ne its sound qualities. ‘We carefully carried out acoustic simulation of the room, so we didn’t really encounter any large problems,’ says Mr Ahn. ‘This was the rst time I’ve worked with Renkus-Heinz; after some evaluation of other brands I thought it would be the most suitable system for the hall. I checked the speci cations and references of the Renkus-Heinz speakers, and when I simulated them to t the space I got very good results. The actual performance of the speakers was very close to what we’d predicted with EASE. I’m Renkus Heinz arrays mounted around large central screens The Ansan Evergreen Gymnasium will host volleyball and kabaddi up to the quarter final stages of the Asian Games Heinz Audio Operations Network) control was another important factor in selecting the system, enabling networked DSP control over the entire system.‘ As for Ansan Urban Corporation’s Mr Kim, he is of the opinion that the speakers offer the best possible functionality for concert sound, providing high SPLs when required. ‘Once we are able to put on concerts here, the system will prove itself as really good for this kind of event, while also being able to provide intelligibility and clarity when the hall is being used for our sporting events,’ he says. The system design was carried out by a team of ve people, including members of Daikyung Vascom’s sales team, together with staff The local council wanted to use the venue as a sports centre as well as a concert hall very satis ed with the system. I also really appreciated being able to use Rhaon to tune the system, especially the mid frequencies.’ Actual building work began in early 2013 following some meetings between Mr Ahn and the building contractors. Mr Ahn’s primary concern was safety. ‘The ceiling of the gymnasium is very high, around 20m, so I needed to ensure that my team of installers would be safe while working so high,’ he says. Mr Ahn didn’t need to make any major modi cations to the room; however the upper section of the walls, adjoining the ceiling, were originally lined with gypsum, which was creating too much re ection in the room. To solve this problem, Mr 94 PRO AUDIO ASIA July–August 2014 Genelec monitors in the control room Ahn has replaced this with an upper section of acoustic tiling. 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. When being used in this con guration, temporary seating can be set up on the oor of the gymnasium, and a total of around 3,000 people can be accommodated. A control room overlooking the main hall has been installed with an Avid Venue console and Genelec monitoring. ‘The client chose the Venue because it’s in use in another building in Ansan, and so we are familiar with it, and we trust it,’ says Mr Kim. ‘I also like the Venue’s multipurpose functionality which will suit the room and the many different events we will host here.’ The control room has also been installed with a pair of Genelec 8040 APM monitors, and Aphex PE232MK2 and DBQzero have also been supplied. A smaller room downstairs in the basement of the building is being used for other sports such as badminton and volleyball, and here, Daikyung Vascom has installed some of its own-range Vascom speakers, the best-selling SRI828. Eight of the models have been installed, with four along each of the room’s long walls. These will be used for music played during sporting events and for vocal applications. The room can accommodate an audience of 200. A further eight Vascom MSC-500LBs have been installed into multipurpose and weightlifting rooms in the sports facility. ‘Our Vascom speakers are very popular in Korea, especially for government projects,’ says Mr Yun. ‘This is down to the stability of the products, and the fact the brand is well known in the country. It also gives both our private and public sector clients the opportunity to invest in a local brand. It’s a very reasonable investment compared with foreign brands.’ Daikyung Vascom also provided more of its own-brand equipment including VEP-816RA CD players, a large selection of wireless microphones and mic stands and VMX-2683Q, VMX-1843QF, VLM- The control room rack 1825Q and VLM-602S audio mixers. Ansan Evergreen Gymnasium now boasts a state of the art sound system to complement its clean architectural design and functionality. The signs are positive that the new sporting venue will contribute to a successful and uplifting Asian Games later this year, providing a panacea that South Korea needs. www.dkvascom.co.kr The smaller badminton hall has also been equipped with a new sound system
