Wide Nave, Medium Height Ceiling

Broad front chancel/podium space and a moderately wide and deep congregation area. Loudspeaker mounting is somewhat limited by a medium ceiling height.

In this example, we have used two matching arrays. Each loudspeaker cluster addresses one-half of the audio system and includes two horizontally oriented (landscape) cabinets with rotated horns. In each array, the upper loudspeaker is aimed to project to rear seats using narrow vertical dispersion angle (in this case 90° H x 40° V). The lower loudspeaker is aimed downward addressing closest seats with a wider vertical dispersion (in this case 120° H x 60° V). Refer to the Side View coverage lines (pink).
 
In some cases, particularly more narrow rooms, each array can be located farther “off-stage” for truer Left / Right “Stereo” coverage. Each array must address all seats to achieve the desired effect.
 
Note: Horns are rotated 90° from factory standard configuration to maintain the coverage pattern. Suggested model families: I SERIES (IP600, IP800, IC600) and V SERIES (V2-6, V2-26, V2-8, V2-28, V2-32, V2-35)
This system shows I SERIES subs positioned behind the main array to offer a tight bass response to the listeners. Coupled floor mounted subs are preferred in most situations for additional low frequency support, but in this case, distributed floor positioned subs would be too close.
For general monitoring purposes a compact loudspeaker mounted below each subwoofer aims toward the front platform.  Portable monitors (MX8, MX10) can be an option for individual stage performers.

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.
