Mosque/Open Worship Center

Reverberant Clear Space

This is 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.

Technical Considerations

Amplified Loudspeaker Controllers

Community recommends our series of Amplified Loudspeaker Controllers (ALC) for all Community loudspeaker applications, like those shown in this application guide. ALCs provide all of the signal routing, zone switching, DSP processing, protective limiting, remote monitoring, and amplification functions needed between a mixer and the loudspeakers in virtually any Community Professional Loudspeakers application. Standard Ethernet communication protocols allow for fast system design, system control, and remote system monitoring. Analog and Dante® inputs are included in each model, for 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.

ALC Application Note

Total available power can be safely distributed asymmetrically across the outputs in any combination of low impedance and 70V/100V loads.  Power delivered from each output is individually managed; total shared power per ALC is monitored and limited independently by the power supply.

ALC-404D

4 inputs (Analog and/or Dante®)

4 channels of amplification and DSP processing

Each channel provides up to 400W of power into low impedance or 70V/100V loads, stable to 2Ω

In bridged mode, each pair of channels provides up to 800W into 8Ω, 4Ω, or 70V/100V loads

Total shared power not to exceed 1200W

Perfect for Small R SERIES, V SERIES, Compact I SERIES,  W SERIES (W2), and ENT200 models, and zoned C SERIES & D SERIES applications

ALC-1604D

4 inputs (Analog and/or Dante®)

4 channels of amplification and DSP processing

Each channel provides up to 1600W of power into low impedance or 70V/100V loads, stable to 2Ω

In bridged mode, each pair of channels provides up to 3200W into 4Ω, or 70V/100V loads

Total shared power not to exceed 4800W

Perfect match for  Larger R SERIES & W SERIES, I SERIES, IV6 and ENT-FR

ALC-3202D

2 inputs (Analog and/or Dante®)

2 channels of amplification and DSP processing

Each channel provides up to 3200W of power into low impedance or 70V/100V loads

In bridged mode, each pair of channels provides up to 6400W into 4Ω, or 70V/100V loads

Total shared power not to exceed 6400W

Perfect for R6-MAX, I SERIES Subwoofers and larger IV6 Arrays
