Fulcrum brings high fidelity to Grace Chapel
- Details
The main loudspeaker location is immediately in front of the proscenium wall. Any rear-radiating energy would reflect off the wall, interfering with speech intelligibility and clarity of music. Additionally, the wide footprint of the audience area required a solution with precise pattern control to optimise coverage.
Nick Moon from Tone Proper AV was chosen to create a high-fidelity sound system for church services and other performances in Grace Chapel’s new sanctuary. Moon installed five FL283T Line Array Modules on either side of the altar for the main coverage. Fulcrum Acoustic’s Passive Cardioid Technology reduces the rear low frequency radiation from the FL283T which would otherwise reflect off the wall. “Most people don’t realise how much low frequency energy radiates from the back of most line arrays; they aren’t as directional as many assume,” says Moon. “Fulcrum’s Passive Cardioid mitigates that leakage without adding all this extra equipment.
“The FL283T presents such an effective use of resources. I love working with it,” Moon continues. “You can deploy a lot of modules without needing too many amp channels. Plus, the vertical coverage from each unit is impressive on its own. We have five FL283Ts in each array but with other products we would need six or seven units to achieve a similar performance.”
The compact Sub218L subwoofers provide ample low frequency support for the system within the small envelope of the concrete cavities built into the altar. “Between the room treatment and the system design, this is one of the best sounding multi-purpose worship spaces out there,” says Moon.
