Presentation Auditorium

Tiered Sectional Seating with Raised Stage

This is primarily a lecture space. It may also host a wide range of activities, including presentations or entertainment events, when it must deliver full-bandwidth audio. It has a raised stage and lower front ceiling necessitating low profile loudspeaker solutions.

Suggested model families: I SERIES (IP600/800, IS600/800) and V SERIES
(V2-6, V2-26, V2-8, V2-28, V2-32, V2-35, VLF208LV)
An exploded array of horizontally oriented medium-format loudspeakers covers each section (Left/Center/Right [LCR]), and in this case subwoofers are mounted behind for full low frequency support. Depending upon the ceiling heights and the depth of the room, the space may be better served with two sets of arrayed loudspeakers (similar to Distributed Source configuration on the Lecture Hall, next page), with one set covering the front half of the seating and another placed about halfway back addressing the upper audience.
Additional stereo loudspeakers can be included to support LCR type events or occasional cinema use.
 
Unless this space is exclusively used for lectures, subwoofers are needed. Due to limited floor space, they can be mounted overhead (as shown).
For a deeper bass impact and more even bass coverage, array compact subwoofers along, or concealed in, the down-stage face of the stage.
Three (3) IP600/800
(various horn patterns)
Each covers a section with subwoofers mounted behind in landscape orientation.
 
An IP8-0002 mid-high with an IS6/8-115 subwoofer mounted behind is another option.
Spaced across the front of the stage area for extra bass support of cinema or musical events.
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
