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, MD, PhD., the eighth and ninth 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 rented space that is the tenth story grand ballroom attempts to keep pace with the worshipping requirements. Having called upon several suppliers to upgrade the visual aspects of the worship experience in 2014 - including PT Harmoni Yogia Into Sellars with Datavideo switchers and recorders - the GBI PRJ committee recently turned to Promedia Solutions (PMS) to enhance the 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 served for ten years, the Q series has been relocated to serve in one of the CK7 satellites, whilst an extensive J-series provides intelligibility and even dispersion within GBI-PRJ. The L-R arrays comprise of six J8 and two J12 three-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 their in-ear monitoring system, the musicians and choir favoured a wedge speaker solution and this has is achieved via 14 low profile MAX2 and two M4 models.
