Asan, South Korea (August 19, 2020)—Yi Sun-sin Stadium in Asan, South Korea is not a small place. Home of Chungnam Asan Football Club, it seats 17,376 fans, and in order to cover them during sporting events, the venue has installed a new sound system based around Electro-Voice loudspeakers powered and processed by amplifiers from Dynacord.
Dlogixs Co., Ltd. (Anyang-si, Kyounggi-do) completed the system design and installation, with manufacturer support from Hosung Lee of Electro-Voice/Dynacord.
The main covered grandstand on the home side of the stadium is the only suitable structure from which to fly loudspeaker clusters; the away-side seating areas directly across the pitch are uncovered. The challenge was to achieve consistent coverage and SPL for both the home and away fans, using a combination of main loudspeakers in the grandstand and delays to cover the away seats. As line-arrays were not a cost-effective option, point-source models with pattern control were selected as a solution.
Weatherized EVH horn-loaded loudspeakers in four vertical clusters of two serve as the mains: longer-throw 90°H x 40°V over wider-coverage 90°H x 60°V. The EVH models are supported by eight weatherized Sx300PI two-way loudspeakers as side fills for the areas right below the main clusters.
Across the pitch, 16 ZX1i compact two-way loudspeakers are distributed to cover the away-side seating areas, with tonal characteristics and delay time carefully aligned to match the main system. Each is pole-mounted inside a weatherproof enclosure and equipped with a TC-ZX1i terminal cover. Additionally, a pair of EVID 6.2 compact two-way loudspeakers are wall-mounted as monitors in the control room. The entire system is powered and processed via a combination of Dante-equipped IPX and L series amplifiers from Dynacord, with optimizing presets for the Electro-Voice loudspeakers.
“The fans are the ultimate judges of a successful sound system installation,” said Lee, “and the response has been very positive.”
