School Auditorium

Deep Sectional Seating

This dedicated performance space may need to cater to a wide range of events.

Suggested model families:
I SERIES (IP600/800, IS600/800) and V SERIES (V2-6, V2-26, V2-8, V2-28, V2-32, V2-35)
For music events, the wide imaging of a Left/Right “stereo” array offers spatial advantages while lecture events are best reinforced by a centrally oriented array. Theatrical events benefit from the imaging capabilities of both, however sight line considerations may dictate one or the other.
 
Ideally these spaces benefit from a true Left/Center/Right layout. Each array must fully address all seating areas. Each portion is addressed separately from the mixing console to allow the mix operator to direct stereo, monaural, or specially panned signals to each array to best support the presentation.
 
It is more important to follow the seating lines and stage width to configure the array for coherent coverage. In some cases single L/R loudspeakers can provide sufficient coverage, but in many cases a pair is needed on both sides to provide enough horizontal coverage. Refer to the Tips and Tricks Figure 2 on page 12.
Four (4) IP600/800
(various horn options)
Two (mirror image) arrays cover the entire space providing 'stereo' sound.
Three (3) IP600/800 (coverage)
Centrally consolidated and arrayed to cover the full audience area.

When possible, distributing subwoofers across the front of the stage offers even coverage, but mounting them overhead may be necessary to preserve floor space.

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
