Grace Kwangsung Church, a new house of worship with a modern multi-purpose design in Seoul, South Korea, is equipped with a sound reinforcement system to support services, meetings, events and concerts that is headed by Electro-Voice loudspeakers driven by Dynacord power amplifiers in a design focused on delivering sonic clarity and uniform coverage throughout the sanctuary.
Won Young Kim, Kim Jin Keuk and Kim Ho Jun of Bosch (parent company of Electro-Voice and Dynacord) worked with regional dealer and integrator dB Sound Interactive and church leadership on the system project. After running a simulation with PREVIEW Loudspeaker Software to determine a model selection to attain the desired coverage, SPL and frequency response characteristics, the system design was finalized.
Six X1-212/120 line array loudspeakers and two X12-125F flying subwoofers per side serve as the mains joined by an EVC-1122-VI variable-intensity model for center fill. Four compact EVU-1082/95 and eight FRI-2082 loudspeakers deliver fill to the over/under balcony areas.
Audio power is supplied by an IPX10:8, an TGX20 and two TGX10 power amplifiers from Dynacord, with control and monitoring provided by SONICUE software. Powered loudspeakers also play a key role at the church, with eight compact PXM-12MP coaxial powered monitors providing on-stage sound and ZLX-BT models available for portable PA support.
The system achieves the requisite high-resolution for spoken word, the flexibility for various community events and the high-output capacity for concert sound. In addition to the audio aspect, the system’s low-profile aesthetics keep sightlines open and compliment the church’s architecture.
“The system has delivered exactly what we wanted – we are very happy,” says Mr. Park, executive pastor at Grace Kwangsung Church. “It’s amazing,” adds Mr. Kim, audio engineer. “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 concludes, “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.”
