--The Moreleta Park Dutch Reformed Church in Pretoria has built a 7,200 seater auditorium for its ever-expanding community which presently numbers 17,000 members.

It was clear that such a state-of-the-art auditorium would require a sound reinforcement system to complement the unique modern design of the venue. Chris Leeson of Claasen Auret Consulting Engineers, and Chris Jonker, the Technical Director of the Moreleta Church, jointly produced a tender which included the requirement for a digital sound system incorporating a CobraNet™ audio distribution system.

The engineering team at Wild & Marr, headed at the time by Tom Crosswell and ably assisted by engineering project manager, Gustav Teitge, put forward a proposal based around a Harman Pro solution. This included JBL Professional® Vertec DP self-powered loudspeakers for the front-of-house cluster, Crown IT6000 amplification, a Soundcraft 56-channel MH4 console, a dbx gate and a number of Lexicon FX processors, while a BSS Audio active splitter is used to provide the broadcast signals.

The system DSP is stored in a Soundweb London BLU-80, which handles the CobraNet processing.

The JBL Vertec DP’s utilise on-board DrivePack™ technology, designed and engineered by Crown International.

The design of the Line Array was carried out using EASE modeling software, and Chris Leeson and Chris Jonker were astounded by the accurate correlation of the theoretical results with the results achieved on testing and commissioning of the system.

The overall system design incorporates HiQnet™, a registered Harman Pro digital protocol which is able to handle system-wide configuration, routing and control.

This includes the foldback system which includes a Soundcraft MH3 48-channel console and JBL SRX712M wedge monitors, powered by Crown IT6000CN amplifiers. These include the CN digital modules which provide the relevant monitoring and control of the system utilising HiQnet.

Co-system designer, Gustav Teitge commented, “The massive venue, with three-level high balconies and a stage that is nearly the size of their old church, is impressive to say the least. The sweeping design also requires a lot of factors to be considered. We worked closely with the architects to make everything happen, both acoustically and practically. The venue will be used for a variety of applications, including services, live broadcasts and concerts. Taking all this into consideration, a compact, yet powerful line array, able to provide both clarity and overall coverage, was essential.”

The Line Array, incorporating 20 JBL Vertec VT4888’s and eight subwoofers, ensured complete coverage of the entire auditorium. The clarity and intelligibility of the system are complemented by the full frequency response and audio fidelity essential to provide modern-day gospel music.

Source/playback equipment and an in-ear monitoring system, together with all the necessary wired and wireless microphones, complete the installation.

In the words of Chris Jonker, “the wiring and general quality of the installation is the best he has ever seen”.

The installation is the first of its kind in the Southern Hemisphere and there is no doubt that it has set a reference standard in the industry for sound reinforcement in Southern Africa.

In addition to the main system, the church has two fully functional breakaway rooms. These are powered by JBL AE Series loudspeakers, with portable racks which can be used for a variety of purposes, including youth concerts and seminars.

The church also has translation booths, a recording studio and an edit suite which is also equipped with Harman products, and makes it arguably the most outstanding venue of its kind in South Africa.

The venue holds up to five services a day, and has played host to a number of international contemporary music concerts.
