L-Acoustics L-ISA brings sound and stage together
- Details
“It’s been clearly shown that when we can connect what we see with what we hear, the technology disappears,” says Josh Maichele, L-Acoustics application manager, house of worship. Specifically, he says, our eyes want to watch a pastor on stage but our ears draw our vision towards the PA speakers reinforcing their voice.
L-ISA technology effectively disconnects the sound from the sound source, allowing audience members to focus their attention on the stage, immersing themselves in the content. “L-ISA makes the connection between sight and sound more natural, and in the process, breaks down the technical barriers to worship,” continues Maichele.
Orchard Hill Church technical director John Cornelius was introduced to L-ISA at the L-Acoustics facility in the Westlake Village neighbourhood of Los Angeles, where worship-technology directors can experience L-ISA first-hand, diving deeper into its technology. “It’s a step-by-step process, starting with a demo of the system and then sessions during which visitors can get hands-on with the mix, using pre-recorded worship tracks,” Maichele explains. “John arrived knowing nothing about L-ISA, and he left excited by its possibilities for Orchard Hill Church.”
Orchard Hill Church’s new L-ISA technology, installed with assistance from integrator Key Code Media and L-Acoustics Certified Provider (CPi) Hollowood Sound, consists of five L-Acoustics arrays spread over the stage that comprise the Scene system, with two smaller outside arrays over the stage wings that make up the extension system. The three centre-most hangs feature five A15 enclosures each -four Focus over one Wide - flanked by two outer hangs of five A10, also four Focus over one Wide. Behind the centre array are two hangs of three KS28 subs each.
On the far left and right side, three A10 hangs of two Focus over one Wide serve as Extension. Between the Scene and Extension arrays on each side are three A10 Focus used as out-fills, bringing the flown array count to 11 hangs. In addition, 14 5XT coaxials are flush-mounted into the face of the stage for front-fill.
The Scene and Extension systems are powered by 12 LA4X amplified controllers, while two LA12X are used to drive the KS28 subs and the out-fill and ancillary speakers, such as the eight X8 used to cover the very last rows of seating. The immersive system is managed by a pair of L-ISA Processors paired with an Avid Venue S6L mixing console, and an Auvitran audio toolbox handles the MADI, AVB, and Dante format interfaces for the audio system.
In terms of hands-on operation, Cornelius says L-ISA quickly went from intimidating to exhilarating. “Once you learn how the L-ISA Controller works and you break your mental mode around stereo, it’s easy and even intuitive,” he says. “And the results are spectacular. It’s a great format for house of worship because we can so precisely locate the sound. That’s nicely experienced during the 20 to 30 minutes of music we have at the beginning of services, but it’s especially useful for the time when the pastor is centre stage - L-ISA keeps the focus totally on him, and it really increases engagement.”
