A Flexible Solution for a New Swedish Church

Inaugurated in November 1930, Stockholm’s Filadelfiakyrkan (Philadelphia Church) belongs to the Swedish Pentecostal Movement. With the church’s popularity expanding, a service program that features small bands, and the intention to rent the building out to touring productions, the decision was made to undertake a complete renovation of the building and update its technical infrastructure.

The Challenge

JLE Audio was asked to provide a new rider-friendly PA system that would provide full coverage for every seat in the house, handle anything from speech to pop/rock music, and stay within their budget. The church also needed a system that would fit the architectural requirements of the building, which called for flown subs.

The Solution

JLE’s Johannes Jonsson, who handled the design, installation, calibration, and tuning of the system, chose Kara II for the main system due to its lightweight and the ability to provide the coverage and sound the church was looking for. The final design comprises main left/right hangs of 12 Kara II per side, with four KS21 flown behind the Kara II per side. An A15 Wide per side caters for outfill, while the frontfill is six X8, with a further eight X8 as under-balcony fills. The entire system is driven by LA4X amplified controllers running on AVB from an L-Acoustics P1 processor and measurement platform at the front of house.

The Result

According to Jonsson, “Using the P1 was a natural choice as we wanted a flexible matrix for the whole system where you can connect both the in-house console and guest consoles, with the ability to connect both via AES or analog. We also wanted the ability to send separately to subs, etc., and have a guest EQ. In addition to this, we want the best sound transmission to amplifiers. AVB/MILAN is unbeatable here, as everything is 100% time aligned and sent with the highest sound quality. As for redundancy, there is an analog fallback from the P1. Another nice feature that the P1 offers is auto-climate integration. 

Jonsson appreciated L-Acoustics’ support and assistance with the Soundvision design and proposals and its help during the demo/shootout. “It feels very good to have a close relationship and support from the manufacturer,” he says. “It has helped us to make the right decisions and take the project to the next level, with excellent results.”

The even coverage is impressive! It sounds the same everywhere, from the first row to the last row of the balcony.
