This system design template describes a typical loudspeaker system layout for a mostly open, large space with structural pillars or columns supporting the ceiling and vaulted spaces. A relatively unobtrusive audio system preserves the architectural themes, and minimizes sound reflections on upper walls and ceilings.
Delivering speech clearly to large spaces with acoustically reflective surfaces must be balanced. To accomplish clear speech delivery, position ENTASYS ENT-FR line array column loudspeakers to direct sound to the intended listeners. Stacked 2-4 module ENT-FR arrays flanking the cleric addresses the majority of listening areas and provides directionality from the presenter. Using these highly directional loudspeakers minimizes impact on the reflective surfaces and microphones.
Nearby listeners can benefit when rear and side wall reflections are directed back to them. This reflected sound can also be partly absorbed by the congregation (when fully occupied) reducing "slap back" effects. In similar larger spaces, supplemental arrays may need to be taller to cover the related distance. Additional loudspeakers may also be needed on all of the interior columns to cover acoustically shadowed areas or to address the extended space. Sometimes, larger delay zones do not integrate well, and smaller zones addressed by single ENT-FR (or ENT200) models better optimize intelligibility.
Below is the list of loudspeaker and amplifier equipment used in this design:
- 4 - Community ENT-FR High Performance Column Line Source System; 200 Hz - 20 kHz (H x V): 120° x 12° or 120° x 6° (2 Stacked Arrays)
- 2 - Community ENT212 Two-way, Compact Column Array Loudspeaker; 120 Hz to 22 kHz, Nominal Beamwidth (H x V) 140°x 15° (Supplemental Arrays)
Amplified Loudspeaker Controllers
Biamp's line of Community Amplified Loudspeaker Controllers (ALC) offers factory-optimized DSP processing, protective limiting and amplification, as well as signal routing, zone switching, and remote monitoring for virtually any Community loudspeaker application.
Standard Ethernet communication protocols allow for fast system design, system control, and remote system monitoring. Analog and Dante® inputs included in each model are assignable per channel in static or failover/backup configuration, supporting quick and easy integration into any new or existing system.
Community-authored loudspeaker presets include equalization, high pass filters, and multi-stage limiters tailored to each model, ensuring consistent sound quality and full loudspeaker protection in every application. Additionally, each Community loudspeaker preset includes loudspeaker power and impedance information, allowing the system configuration software to display the total power and impedance of multiple parallel wired loudspeakers, further reducing the time and effort required to match complete loudspeaker systems with the appropriate ALC models and output channel configurations.
In-depth control and monitoring is accomplished via ArmoníaPlus® system manager software.
