Tall and Narrow

Long narrow congregation area with tall sloping ceilings, full-width chancel space and extended two-level rear seating.

Long narrow congregation area with tall sloping ceilings, full-width chancel space and extended two-level rear seating.

Though hard interior surfaces and high ceiling heights can enhance choir and instrumental music, the same soaring space can also degrade speech and blur faster tempo music. Highly directional loudspeakers can improve music and speech clarity by limiting the vertical dispersion (and reverberation). We suggest using distributed column-format E SERIES loudspeakers to focus the sound on the congregational areas. Use of signal delays will allow the listeners to perceive the sound as coming from the platform areas. This example also shows rear balcony seating, but extended seating could also be on the side or as flanking balconies. Smaller column or other directional loudspeakers can cover those areas.

Four (4) ENT212 (Main seating)
Two forward of the platform covering the front half and two in the middle covering the rear half 
 
Four (4) ENT206 (Extended and upper balcony coverage)
Two up addressing the balcony seating and two down focused on the center of the rear extended congregational area
 
For increased fidelity, single ENT-FR modules can substitute for each of the ENT212 column loudspeakers mentioned above.

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.
