ET Quake Multimedia Rocks Nigeria’s “House On The Rock” With JBL VERTEC® Powered Line Arrays

NORTHRIDGE, California – In a house of worship installation that showcases the easy configuration capabilities of JBL VERTEC® line arrays, Nigerian systems integration firm ET Quake Multimedia recently upgraded the audio system at The Refuge in Abuja, Nigeria, a branch of the Lagos-based House on the Rock Church. UK-based independent consultant Roland Hemming provided system design assistance, relying on the superior performance characteristics of VERTEC® DP Series powered line arrays with JBL DrivePack™ technology to provide the facility with a clear, powerful full-bandwidth sound reinforcement system.

Built in 1999, The Refuge is one of 40 House on the Rock worship sites and mission facilities in Nigeria. Pastor GoodHeart Obi C. Ekwueme leads The Refuge, which acts as a springboard for strategic ministry operations in northern Nigeria and beyond. As the evangelical organization has expanded, so has its need for improved, high-performance audio systems for its churches.


The Refuge’s new main PA system features two arrays in a left-right configuration, each containing 10 JBL VT4887ADP-AN powered compact line array elements, and three JBL VT4880A ultra-long excursion, dual 18-inch arrayable subwoofers. Using onboard amplification and digital signal processing technology designed in cooperation with Crown and dbx, each JBL VT4887ADP-AN compact line array loudspeaker contains a DP-2 DrivePack, providing 2,200 watts peak (1,100W continuous) output power. With suspension hardware including quick-release pins and end-mounted metal frames to couple adjacent units together in rigid but flexible arrays, the VERTEC loudspeakers helped simplify the installation process. “The VERTEC line arrays were a very good fit for this project,” Hemming said. “They were easy to configure and the actual installation of the loudspeakers, with all the rigging, took less than a day.”

Complementing the main line array system are eight JBL AC28/95 loudspeakers dispersed throughout the worship space as delay fills. A total of 16 VRX915M stage monitors are available to serve the venue’s performance-based worship services. Crown MA12000i and MA5000i amplifiers power the loudspeaker elements not equipped with JBL DrivePacks, while the system also features a Soundcraft MH3 mixing console at the front of house position. Signal processing is achieved with dbx DriveRack 4800 Loudspeaker Management Systems, and a variety of AKG microphones round out the new system installation.
