South Korea’s Yeouido Full Gospel Church

When old and outdated amplifiers began to cause frequent errors at South Korea’s Yeouido Full Gospel Church, an upgrade was imperative. Audio specialists and Powersoft distributors, Dasan SR, presented the winning specification, proposing Powersoft’s X Series amplifier platforms to manage the high channel count and the complexity of the church’s sound system. The church claims the country’s largest Pentecostal Christian congregation of over 800,000 members.

Dasan SR’s technical manager, Changyu Choi, specified seven of Powersoft’s eight-channel X Series tour-grade amplification systems to drive the PA comprised of EAW KF750 full system three-way cabinets and associated KF755 down fill array modules. The extensive PA is comprised of main front of house loudspeakers including downfill, front fill and under balcony, as well as the delay system, the choir and side.

Flexibility and stability were cited as contributing factors, but performance and price sealed the deal on Powersoft’s X Series. X Series is set apart by its new and innovative level of signal processing, providing routing and mixing matrix, as well as multi-stage equalization with raised-cosine, and TruePower limiters.

“The key, however, was the greybox support,” insists Choi. Powersoft’s DSP+D amplifiers – like the X Series – natively read and load EAW greybox presets, aligning the loudspeakers with the powerful technology contained within Powersoft amplification.

Powersoft’s ArmoníaPlus facilitates the simple process of system management, uniting the loudspeakers with universal switch mode power supplies with Power Factor Correction (PFC) and patented Class D technology.

The system installation was carried out with no disruption to worship, as work continued either side of the service day. Once the space-saving, 2U X4’s were in place a Dante network was created to alleviate the use of the pre-existing DSP. Powersoft’s ArmoníaPlus then took over the reins and tuned the entire speaker system. Armonía handles complete monitoring of the amplifier and speaker status from anywhere, which is useful when the distance between the amp room and the front of house is too great – as it is in Yeouido Church.

The system set up and tuning was all handled by Choi and ‘very intuitive’ thanks to Armonía. He also found the matrix nature of the Powersoft X4, ‘assisted greatly with installation and adjustment’. He adds, “The matrix function, allowing you to send one or more inputs freely to all outputs, is very attractive.” Choi worked with Yeouido’s sound engineer, Joung Kim to organise the input and output channels and to stabilize the system.

Kim states: “The Powersoft products are very stable and reliable. The control of the system now is very simple, with no need to manipulate the system at all now the set-up is complete. Power on / off is available remotely which is very convenient and all we need to do is monitor the system status.

That the amplifiers support their own Dante network is invaluable as it now bypasses the original network. I’m very happy with how the installation went. The Powersoft X Series is designed with excellence and the hardware is very stable. The next important install we do here will definitely by with Dasan SR and the specification of Powersoft was the right choice for us.”
