Indonesia: Having resided at the Integrity Convention Centre (ICC) in Jakarta’s Mall Mega Glodok Kemayoran since 2008, the GBI Praise Revival Jesus (PRJ) has evolved significantly. Under the watchful leadership of Pastor Dr Janto Simkoputera, PhD. the ninth and 10th levels serve as the main church headquarters for eight smaller CK7 satellites in the Indonesian capital city. Just as the congregations have grown, the A/V technology within the rented space that is the 10th storey grand ballroom attempts to keep pace with the worship requirements.
Having called upon several suppliers to upgrade the visual aspects of the worship experience in 2014 – including PT Harmoni Yogia Inti Sellaras with Datavideo switchers and recorders – the GBI PRJ committee recently turned to PT Promedia Innovative Solution (PIS) to refresh its audio system. Enhancement of the stage monitoring together with side-, rear- and front-fills dictated the supply of a d&b audiotechnik system four years previously. Supplementing the FOH Q series speakers, Max12 wedge monitors, six ceiling suspended Qi7 delays, five Qi10 front-fills and a single V10P central cluster powered by D12 amplifiers literally filled the gaps.
Having been in use for 10 years, the Q series has been relocated to serve in one of the CK7 satellites, while an extensive J-series now provides intelligibility and even dispersion within GBI-PRJ. The L-R arrays comprise six J8 and two J12 3-way cabinets per side, providing 80° and 120° horizontal dispersion respectively. The wide room dimensions require side-fills for its capacity congregation and these are catered for with the addition of four per side V8 cabinets. Low frequency extension is further enhanced in the form of six J-Sub and two J-Infra subs ground stacked in front of the stage. Having dispensed with an in-ear monitoring system, the musicians and choir favoured a wedge speaker solution and this is achieved via 14 low profile MAX2 and two M4 models.
In the four intervening years between PIS being called to GBI-PRJ, d&b audiotechnik significantly enhanced its inventory of amplifiers. Remotely controllable via the d&b Remote network, through either Ethernet or CAN-Bus, the latest d&b amplifiers incorporate DSP capabilities for comprehensive loudspeaker management, switchable filter functions, remote capabilities and user-definable controls.
Five 30D cater for the stage monitors, while nine D80 amplifiers are required for the J-series and V-series modules and subwoofers. Sixteen-band equalisation including parametric, notch, shelving and asymmetric filters together with up to 10s of delay can be applied to each of the amplifiers’ four channels. The 30D and D80 amplifiers also incorporate active Power Factor Correction (PFC) to maintain a stable output when used with weak or unstable mains supplies.
CK7’s satellites will be anticipating GBI-PRJ’s next audio upgrade in approximately 10 years’ time. ‘d&b reseller values have always been very high as their products hardly deteriorate over the years and consistently provide audio quality that maintains their position on the main touring riders,’ comments PIS director Yosua Yan Heriyanto. ‘GBI-PRJ’s congregation has provided us with great reviews of this new audio system, so we are very happy.’
