The sanctuary rejects both rectangular organisation and symmetry, similar to the Berlin Philharmonic hall. Its concrete finished wall was influenced by the Opera house in Sidney. This abstract design makes achieving crisp, clear sound very difficult.
The church's staff closely reviewed proposals with the top 5 industry leading sound companies designs for matching its architecture and decided that Adamson's SpekTrix line source array system presented by Acoutek was the most suitable.
Sam Toyoshima, who is well known for acoustic design, was called in to solve the problems caused by a glass wall on one side, the asymmetric balconies and a very high ceiling. He designed a wooden reflector / absorber for better ambience, and installed rotatable pillars which have two different sides; one made of fabric, and other of wood, which are rotated according to material performed.
After listening to many of the top sound systems in various Korean churches, including Adamson systems at the Moohak Church and Suji Yongnak Presbeterian Church, Kim Eun Ka decided that the SpekTrix line source system was the best option for Daedeok church's main sanctuary.
For each of the two main hangs, one SpekTrix Sub at the top, six 5 degree SpekTrix enclosures, and three 15 degree Spektrix Ws as downfills were installed. Six Adamson 10MX monitors are placed on stage and a Midas Legend 300/48 channel console graces FOH position.
The Adamson cabinets are processed by Dolby Lake and powered by Lab.gruppen amplifiers. The multipurpose sub hall has a small installed sound system consisting of two SX18s and one CB-1 cabinet. This setup is also powered by Lab.gruppen, processed by Dolby Lake and run through a Midas Venice 320 board.(Claire Beeson)
