An Electro-Voice and Dynacord system is setting a new standard for house of worship sound in South Korea at Grace Kwangsung Church in Gangdong-gu, Seoul.
The newly constructed church features a modern multi-purpose design and required a versatile sound system to accommodate the services, worship meetings, church events and concerts intended to take place there. The top priority was to ensure clarity and uniform coverage for the congregation during church services.
Won Young Kim, Kim Jin Keuk and Kim Ho Jun of (Electro-Voice and Dynacord parent company) Bosch worked with regional dealer and integrator dB Sound Interactive and the church leaders to specify a solution to precisely address their performance and budget requirements. After running a simulation with Preview Loudspeaker Software to determine a model selection providing optimal coverage, SPL and frequency response characteristics, a system design was finalised. The result combines exceptional acoustic performance with low-profile, architecture-friendly aesthetics.
Six X1-212/120 line array loudspeakers and two X12-125F flying subwoofers per side serve as the main system, with a single EVC-1122-VI variable-intensity model for precise centre fill. Four ultracompact EVU-1082/95 and eight FRI-2082 loudspeakers serve as fill for the over/under balcony areas.
The installed system is powered by a combination of a single IPX10:8, a single TGX20 and two TGX10 power amplifiers from Dynacord, with system control and monitorng via SoniCue Sound System Software. Active loudspeakers also play a key role at the church, with eight compact PXM-12MP coaxial monitors providing on-stage sound, and ZLX-BT models on-hand for portable PA support when needed.
The installation achieves the requisite intelligibility for the spoken word, the flexibility for various community events, and the high-output capacity for concert sound. In addition to the audio performance, the system’s low-profile aesthetics keep sightlines open, and compliment the church’s modernist architectural design.
‘The system has delivered exactly what we wanted – we are very happy,’ says Mr Park, the executive pastor at Grace Kwangsung Church. ‘It’s amazing,’ adds audio engineer Mr Kim. ‘The system gives us great coverage throughout the church and with SoniCue I can monitor and control the system easily and effectively.’
Mr Kim of dB Sound Interactive is equally pleased with the outcome: ‘The X1 arrays are a solution we can trust to provide coverage from the front to the back of the hall. We didn’t even use processing at first and it still sounded fantastic. Many thanks to the Bosch team for technical support and advice on this project.’
