Kwanglim Church premieres d&b install amps with ArrayProcessing

Published: WORSHIP

KOREA: Seoul’s Apgujung Kwanglim Church has been equipped with d&b audiotechnik sound reinforcement to solve historical acoustic issues. The church has also become one of the first projects in the region to be equipped with the German manufacturer’s 30D and 10D installation-specific amplifiers while using ArrayProcessing technology.

Originally constructed in 1978, the Apgujung Kwanglim Church in Gangnam, Seoul, South Korea was designed to accommodate the sound from the huge pipe organ that dominates the stage to this day. The marble pillars left and right of the stage, the enormous floor to ceiling stained glass windows, the polished wood walls and the extensive balcony that protrudes long and low over the floor seating, all contribute to a space with a plethora of acoustic challenges, noted Jung Hawon, one of the elders in the Apgujung Kwanglim Church in Seoul and chairman of the Broadcasting Department.

‘Our church has historically suffered from awful sound; low intelligibility and very reverberant sound due to the acoustics of the worship space which was designed for the more traditional style of Christian worship, with pipe organ accompaniment. Of course, times have moved on and we now offer different styles of worship to suit all generations: traditional including choir, organ music and sermon, and contemporary with band music and sermon. Our Sunday services are broadcast to other countries, such as Japan and France, so it is not just 3,800 worshippers in the hall who hear us.’

Mr Hawon reported a rigorous process that included the congregation’s input was undertaken to determine what equipment would anchor a new sound system to address the facility’s issues. A group from the 80,000-strong global worshippers were provided with a form of grading sheets so they could rate the three systems vying for the contract. The d&b audiotechnik V-Series system, augmented by some E8 loudspeakers and driven by d&b’s newly developed 30D and 10D installation amplifiers won the day.

Armed with the congregation’s preferences, Mr Hawon undertook an additional independent investigation. ‘Before making the final decision, I researched and visited some of the churches and arts centres where d&b systems have been installed,’ he explained. ‘Without exception, they were all very satisfied with the quality of the sound, the after sales service and the supportive attitude of d&b audiotechnik Korea. I felt very confident that we were making the right decision from a quality point of view and extremely fortunate that we were able to acquire the same quality as these other venues but at a lower cost due to the new amplifiers.

‘The cost always has to be one of the decisive factors when one is contemplating a sound system installation,’ he continued. ‘The opportunity to use the brand new specialised installation amplifiers, the 10D and the 30D, from d&b audiotechnik meant that the savings, when compared to other quotations, were more than persuasive.’

Mr Hawon clearly understood there would be many hurdles to overcome, and spoke to Kevin Kim at d&b audiotechnik Korea for advice. ‘I explained that the new amplifiers can deliver ArrayProcessing to installed line array systems, so in addition to the cost saving, the church would still have access to the features available on the more familiar D20 and D80 amplifiers,’ commented Mr Kim. ‘The 10D is for the E8 loudspeakers and the 30D for the V-Series including the V-Subs and J-Subs on the specification. Between them the two models cover almost all install applications and the DSP capabilities can accept new updates from d&b firmware making them future-proof investments.’

Once the hardware was installed, d&b regional application support and education manager, Gert Sanner visited to help set the system up. ‘This was quite a tricky task with all the acoustic challenges. Once all the measurements were acquired we went onto setting up ArrayProcessing on the 30D amplifier – for our first time ever. I have to say it sounded pretty special. The balcony that previously used to be a little loud at the front now featured a very even coverage and we achieved tonal balance in the whole auditorium.’

And the end result from Kwanglim’s perspective? ‘Before the installation, my hope was that changing the system to d&b would produce a positive improvement and create a more immersive worship experience for the whole congregation, regardless of worship styles,’ says Hawon. ‘I can honestly say that my expectations have been surpassed. The entire congregation, staff and ministers are very satisfied.

‘I was fortunate enough to get the chance to hear before and after applying ArrayProcessing,’ Mr Hawon concludes. ‘Even though I don’t consider myself to be an expert, I could clearly hear the difference. To me, this means that worship experiences can be identical regardless of seating locations. I believe d&b audiotechnik describe this as ‘democracy for listeners”.’
