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.

AMPLIFIER

For maximum system performance and longevity, the loudspeakers must be properly powered to achieve the needed sound pressure level (SPL) in the listening area.  Refer to the product spec sheets for appropriate amplifier ratings.

PROCESSING AND PROTECTION

To properly process, equalize and protect the loudspeaker systems, it is recommended to use the Community dSPEC226 digital signal processor.

Some amplifiers have built-in processing which may be adequate when properly programmed. Community's suggested DSP settings can be found HERE.

All of the loudspeakers require an electronic high pass filter for protection against over-excursion from bass-heavy program material.

Loudspeaker protection on the dSPEC226:
Protection is handled by three stages of protective limiters: these include a short-term peak limiter to prevent over-excursion of drivers and to control amplifier clipping; a mid-term RMS limiter that prevents system overdrive; and a unique long-term power monitor that works to protect your loudspeakers from long-term thermal damage.  All three limiters operate interactively, providing unique driver protection, while allowing each loudspeaker’s full dynamic range to be utilized without compromise.

 

WIRING

When considering the distance between the amplifier and the loudspeaker(s), the following minimum cable gauges are suggested.

Less than 50 feet: 14 AWG
50 to 100 feet: 12 AWG
100 to 250 feet: 10 AWG

It is strongly recommended that all loudspeaker level wire be stranded, twisted and never shielded. Loudspeaker wires should not be connected to earth ground or supporting structures.
