Powering prayer for 800,000


Yeouido Full Gospel Church has a huge following that keeps growing. When Worship AVL last reported on the South Korean church in 2017, it boasted a congregation of 500,000. Less than two years later, Yeouido Full Gospel’s membership has risen to more than 800,000 worshippers. While no building is large enough to host the entire congregation at one time, the numerous services throughout the week and running all day on Sunday still draw extremely large crowds from South Korea’s largest Pentecostal Christian congregation, and a working sound system is vital to ensure that everyone gets to be part of the experience.

So, when the church’s old and outdated amplifier setup started to encounter frequent errors, an upgrade became immediately necessary. Dasan SR, a pro audio consultancy and distributor of, among other brands, Powersoft, presented a solution in the form of the Italian amplifier manufacturer’s eight-channel X Series tour-grade systems to power the sanctuary’s main PA setup, which includes EAW KF750 loudspeakers with KF755 down-fills.

Dasan SR’s technical manager, Changyu Choi, designed the solution, which resulted in the installation of seven X4 amps, taking into account the church’s need for both flexibility and stability. The price and performance offered by the system also helped as it won over bids from other manufacturers.

‘The key, however, was the greybox support,’ explained Mr Choi. Powersoft’s DSP+D amplifiers, including the X Series, are all capable of natively reading and loading EAW’s greybox presets, aligning the loudspeakers with the amplifiers. Powersoft’s ArmoníaPlus software handles system management, pairing the loudspeakers and universal switch mode power supplies with Power Factor Correction (PFC) and patented Class-D technology.

Mr Choi also explained that the Powersoft X4’s matrix features assisted greatly with installation and adjustment. ‘The matrix function, allowing you to send one or more inputs freely to all outputs, is very attractive.’

Yeouido Full Gospel’s sound engineer, Joung Kim, worked alongside Mr Choi to organise the input and output channels and to stabilise the system. ‘The Powersoft products are very stable and reliable,’ Mr Kim confirmed. ‘The control of the system now is very simple, with no need to manipulate the system at all now the setup 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.’
