A combined Proel and Axiom sound reinforcement system has been installed at Oasis House, Trinity Baptist Church’s brand new facility converted from a large warehouse in south London. Originally founded by Pastor Kingsley Appiagyei, Trinity Baptist Church has grown over nearly two decades with followers now reaching several thousand worldwide across the UK, Italy, Norway, Denmark, and Ghana. Oasis House encompasses a 900-capacity auditorium and main worship space, a sports hall, a café, numerous meeting and training rooms, and childrens’ play areas – and all are equipped with state-of-the-art audio and video communications systems.

Following a demonstration of an Axiom PA, the church turned to Proel’s design team who prepared an EASE simulation and offered a solution for the main auditorium consisting of a centre cluster line array with delayed front fills and floor-mounted SW215 subwoofers under the stage. “The shape of the room and the raked seating layout immediately suggested that a single centrally placed source would work well, providing a stable image and optimal arrival times for the whole audience,” said Daniele Massaccesi, Proel’s Export Sales Engineer.

The project was installed and managed by London-based Lagniappe, who were quick to realise that the requirement to relay sound to all areas of the ultra-modern facility led to increasing complexity, and the eventual installation of an Axiom line array and a comprehensive 32-zone audio distribution system.

The main PA system is composed of eight Axiom AX2065P compact passive line arrays, a dual 6.5-inch two-way model with 110° horizontal coverage, and hung in two columns of four cabinets over the centre of the stage to cover the entire auditorium. These are supplemented with two pairs of SW215P dual 15-inch subwoofers located under the stage at left and right. ED23P passive dual 3.5-inch front fills are built into the risers of the central steps, and ED25P passive dual 5-inch front fills are fitted into the wrap-around wings of the wide stage. Ten CX15A powered co-axial stage monitors can be cabled into any of 16 stage concealed stage box positions.

At front of house, a Cadac CDC eight-32 full frame digital live sound console with dual 24-inch touch screens and 32 input faders mixes the 16 onstage mic channels and the multiple feeds from the live band at the side of the stage. The audio system is driven by three QC4.4 four-channel DSP amplifiers, and two QC2.4 two-channel DSP amplifiers, all networked with PRONET AX software and connected to a laptop up at the main desk, so that the speaker system can be monitored remotely and fine adjustments made as needed.

The distributed audio system has expanded to become a complex configuration that covers the entire building. “We started off with an eight-zone system, and realised very quickly that they needed a lot more, and actually we have ended up with a total of 32 zones,” said Lagniappe’s project manager Roddy Maharaj.

The Proel communications system extends to cover a 300-capacity seating area behind glass at the rear of the main auditorium where the audio can be relayed from the service; six first floor training rooms; nine ground floor training rooms; a crèche; children’s play rooms; a café; the 500-capacity sports hall; the pastors’ main suites and training rooms; the pastors’ reception rooms; and the main lobby. Four MATRIX88 units form the heart of the system – centrally racked up alongside a SOURCE CD/MP3/FM tuner, an AMIX63 nine-channel mixer, five AUP4125S four-channel amplifiers, and four AUP4250S four-channel amplifiers.

Proel ceiling speakers feature prominently throughout the installation. XE51CT 5-inch full range models are used for the majority of the small training rooms and the main lobby area, and for the café and the auditorium’s overspill areas upstairs CS30HFT 6.5-inch two-way ceiling speakers provide wider frequency response and higher output to reflect the energy of the musical content of a service.

“For a modestly sized system the PA reaches easily up to the back of the main room,” commented Joseph Arthur, Oasis House’s chief sound engineer. “We are extremely pleased with the result, and we are already looking at developing further projects both here in London and abroad.”
