Case Study: First Assembly, Calgary

Three dimensional sound and immersive experiences are arguably an extravagance suited to famous concert halls and exotic experimental music. But imagine those principles applied to a church for the first time.

For the pastoral team at First Assembly, Calgary a d&b audiotechnik Soundscape provided an affordable solution to a seemingly intractable issue between acoustics, worship and sound reinforcement.

Justin Wells, First Assembly’s Technical Director, saw an uncomfortable divide between parts of their congregation and the heart of music worship. “Music is a huge part of what we do and within our church we have highly skilled musicians. For people who come for that, it has the potential to be inspiring. For our sanctuary, what we sought was an audio system that could place everyone in the sweet-spot of the sound image, something that could reach those seated at the periphery of our 240-degree fan shaped room and give them that inclusive experience.”

Wells and Executive Pastor Shane Penney called upon the services of Sapphire Sound, an audio, video and multimedia specialist headquartered in Abbotsford, British Columbia with a permanent office in Calgary. “We had worked with the church on a number of things in the past,” explained Ben Burrell of Sapphire. “Lighting upgrades, small pieces of kit here and there, that sort of thing – but this was to prove a project of different magnitude.

“They really wanted a quality experiential dimension to audio and imagined stereo imaging for everyone. Our analysis showed that while this was entirely possible, the room dimension and physical shape would require an unusually large number of cabinets to achieve what they wanted. It would also be a remarkably complex system to manage.”

Burrell continued. “We completed the assessment right about the time of the official launch of d&b’s Soundscape system. While we had no direct experience with Soundscape we have great confidence in d&b; everything we had used from them so far performed exactly as they promised it would. The functionality of their object positioning tool within the EnScene module of Soundscape presented a much more manageable solution to the dilemma of First Assembly, and in many ways a better and more creative one.”

Wells took the proposal in stride. “When Ben first presented the Soundscape concept it was not simply ‘another way of achieving what we aimed for.’ We had started to see the conversations in the pro audio press about so-called immersive sound experiences, so even though it was all pretty new, we saw the potential. Looking at the d&b online videos it was clear this was something else.” Burrell arranged for Wells and Penney to attend InfoComm and witness a d&b Soundscape demonstration. “The demo was the final stamp of approval.”

Burrell received the green light two days later and Sapphire placed the order with d&b audiotechnik Canada. “Although this was to be our first Soundscape installation, and the first in a house of worship for d&b anywhere in the world, one element was in our favor. Typically Soundscape requires more channels of amplification than a more conventional point source solution. But such a conventional solution to First Assembly’s listening area was already complex enough that a high amplifier count was a given; in fact, using Soundscape has reduced the number of cabinets required and consequently reduced the amp count. The only cost impact was the d&b DS100 signal processing engine and the En-Scene license.”

“With the audio system we made a clear decision that it was the most important component of the changes we were making and as such it was an easy decision to postpone some investment elsewhere,” Wells said. “It was a sacrifice, but a small one and the cost was not a huge impact at all, certainly not compared to the impact the system has had.

The system Sapphire installed consisted of components from d&b Y and E-Series loudspeaker ranges, with Bi6 and 27S SUBs, all driven by d&b 30D and 10D installation amplifiers. Sapphire also supplied an A&H dLive-S5000 mix console with dLive stage rack, card adaptor and Dante card. For commissioning and familiarization with the Soundscape system, Sapphire were supported by Francois Corbin and Trevor Nash from d&b Canada, plus Asher Dowson, House of Worship segment manager for d&b GmbH.
