Indonesian install for L-Acoustics’ K1

Indonesian install for L-Acoustics’ K1

L-Acoustics’ distributor in South East Asia, Sennheiser Electronic Asia, and Indonesian partner Tri Tunggal Abadi have installed the first K1 system into a church in the region.

The K1/KARA WST line source system has been installed into the Evangelist Graha Bethany Nginden Church, located in Surabaya, together with products from almost all L-Acoustics ranges.

Tri Tunggal Abadi’s André Bonang has carried out several previous installations for the Bethany Church in Indonesia, including the Bethany Manyar.

Michel Brouard, L-Acoustics’ sales manager Asia, initially visited the Graha Bethany Nginden church in March 2010 and met with Pastor Tanuseputra. Following his visit, L-Acoustics tech support engineer Germain Simon and head of installation support Cedric Montrézor carried out an acoustic simulation using L-Acoustics’ proprietary Soundvision program.

The system that resulted from this process consists of two hangs of 12 K1 WST line source boxes with six K1-SB and six SB28 subwoofers in cardioid mode. Two clusters of four KARA boxes provide stereo infill, with a further two used for out fill and four ARCS medium format WST line source cabinets for front-fill. Five hangs of two KARA boxes provide first delay under balcony, together with four hangs of two 12XTi coaxials and four hangs of eight 8XTi coaxials in white, from L-Acoustics’ Architectural Series. Four hangs of three KIVA ultra compact WST line source cabinets have been installed as a delay system for the second balcony. The system is driven by 35 LA4 and LA8 amplified controllers.

In addition, three KIVAs and a KILO cover an on-stage VIP section, while four 115 XT HiQ coaxials driven by an LA8 amplified controller provide the Pastor’s main monitor system. Two 112Ps are used for both side fill and choir monitors.

Germain Simon, who tuned the system, commented: “The large, architecturally complex venue restricted the location of different clusters due to its many pillars. We spent time prioritising the best location for each part of the system with the right orientation, levels and delay. Then we worked on fine-tuning the system, experimenting until we found the most appropriate contour for the type of music and preferences of the church followers. We wish to thank all the Bethany Church sound engineers for their valuable help and support.”
