The WorshipCentre Christian Church in the Brisbane, Australia suburb of Carina has recently upgraded its technical infrastructure with a new public address system. Production Audio Video Technology Pty Ltd (PAVT) recommended the versatile Powersoft X series amplifiers to power an EAW system. Carrying out the installation was third party HOW specialists, CPC Production Services.

The system deployed had to provide even coverage to a seated areas which can house approximately 1,000 congregants. David Watson, project manager, stated that the requirement had been for a Pentecostal style church and said: “This included good intelligibility for spoken word, as well as great energy transfer for modern music styles including full band and concert style presentations.”

The room was modeled using the EAW proprietary modeling and optimisation software, Resolution. Watson said: “The building design had some challenges that required some acoustic treatment of surfaces, with the need to keep as much of the PA energy away from the surfaces as possible.”

Ben Clarke, sound designer, said: “We needed to make sure we delivered clear, coherent hi-fi style sound to the seated areas.“

PAVT chose to pair the Powersoft amplifiers with the EAW KF740 line array. Ben Clarke, sound designer, said: “The X Series has incredible and precise control over the EAW speaker elements that made up the system, allowing the delivery of highly accurate and coherent results.”

The Powersoft amps were configured with one X8 running six cabinets of 4-way EAW KF740 line array on the left wing — repeated with another X8 running the right hang of six cabinets. A Powersoft X4 drives the EAW QX564 bi amped speaker cabinet, acting as sidefills. Two channels are assigned to the high and low, while the remaining two channels run front fill JF8 speakers. This is repeated, with another X4 powering the other PA flank.

In addition, a pair of Powersoft K20 amplifiers have more than enough headroom to drive four EAW SB2001 dual 21-in subwoofers, with each output channel running one enclosure. These subs require 4000w at 2 ohms running power with transients of all 9,000W.
