Community Theater - Option 2

Sloped Seating with Balcony

A fully equipped performance venue that hosts local, regional, and national acts, this medium-format performing arts hall offers broad seating areas on the first level plus additional balcony seating.
A medium to large-format loudspeaker array addresses the majority of the first floor seating. In this case, a set of three IP8-1153/64s arranged in a monaural exploded array reinforces on-stage action while preserving localization for the audience. The main array’s coverage partially extends into the under/over balcony areas, but supplemental loudspeakers (IC6-1082 under balcony, IC6-2082 over balcony) ensure uniform coverage. Having supplemental fills allows for specific system adjustments to cover each area that acoustically differs from the larger open main floor space.
For purpose-built venues of this type, subwoofers can often be integrated into, or perhaps concealed within, the stage front. Where possible, array the subwoofers evenly across the front of the stage to avoid the “power alley” effect caused by positioning them at the extreme right & left of the proscenium. Overhead subwoofer suspension may warrant cardioid or forward-steered arrays to raise bass levels in the seating while preserving GBF (Gain Before Feedback) on the stage.
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
