Changsin Church whittles down the competition to Alcons

Korea:

Changsin Church in the Gangnam district of Seoul recently updated its sound setup to an Alcons Audio LR14 pro-ribbon system as the old audio system was showing its age, both in regards to its sound quality and aesthetics. The installation was carried out by Sky Sound and Alcons Audio distributor Corelab.

Sky Sound and Corelab have worked together previously on a similar project at Gyeongsan Central Church. When Sky Sound was approached by Changsin Church sound engineer and executive director of the Korean Church Acoustics Association Jang Young-wook to take part in a comparison between eight different audio brands, it therefore made sense to partner with Corelab once again and, as before, offer an Alcons solution.

The representatives of all eight brands attended a site briefing and all were asked to suggest a solution based on an identical budget. Baek Seung-hoon from Corelab suggested that an Alcons pro-ribbon system would deliver the best sound for church sermons and that it would be the easiest system for church officials to use while also improving the visual appearance of the worship space.

‘There was a certain amount of reflection and a balcony at the back, with chairs underneath, so I had to be very careful with the sound,’ he explained. ‘The existing system also had cables visible in many places, which detracted from the interior appearance.’

Each company had two weeks to form a proposal. Seung-hoon visited the church during that time when no worship services were taking place to discuss the acoustics with Changsin’s part-time sound engineer. He also visited a Sunday service to listen to and make a recording of the pastor’s sermon through the existing setup.

With his research complete, Seung-hoon designed a system comprising six LR14/90 ultra-compact line array modules, six LR14/120 wide dispersion ultra-compact line array elements, two LR14B ultra-compact line array bass modules, four VR8 compact monitors and one CCS8 medium-format surround unit. The setup is powered and controlled by two Sentinel10 amplified loudspeaker controllers and reportedly provides even coverage throughout the sanctuary, including both above and below the balcony, negating the need for any fills. This design was chosen as part of a final four to demonstrate the system to church officials, during which Seung-hoon spoke of his earlier visits to the church and explained why the existing system failed to reinforce the pastor’s sermons. Impressed with both the demonstration and Seung-hoon’s explanation, the committee ultimately chose the Alcons LR14 system.

During the installation process, the Sky Sound team faced some challenges in removing the old system and flying the pro-ribbon arrays. As a result, bespoke wall brackets were made to hang the arrays from.

‘Before installing the Alcons system, not everyone present could properly hear or understand the pastor's sermons,’ concluded Seung-hoon. ‘Now, everyone in the church can hear every word and the pastor no longer needs to preach loudly, which was making him tired when using the old system. The walls of the chapel also no longer look ugly with a lot of speakers and cables.’
