Football Field

Scoreboard

R2-52Z or R2-52MAX loudspeakers are mounted to the scoreboard 25 feet above the ground.
 
The bleachers are assumed to be 20 feet tall at the back row.
 
Atmospheric effects such as wind, diffraction, and excess high frequency attenuation are more likely to be noticed in this design.
 
If the length of the home or visitor bleachers exceeds the 20-20 yard line, additional R2-52Z loudspeakers should strongly be considered for one or both sides.
Two (2) R2-52MAX
 
Best coverage for shorter bleacher sections from a scoreboard location.
Two (2) R2-52Z
 
Good coverage for shorter bleacher sections from a scoreboard location.
Three (3) or Four (4) R2-52Z
 
The additional R2-52Z loudspeaker(s) provides enhanced SPL at long distances or covers longer bleachers.

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.

 

R.25-94Z: 400W to 600W @ 8 ohms per loudspeaker
R.35COAX: 400W to 600W @ 8 ohms per loudspeaker
R.35-3896: 800W to 1200W at 8 ohms per loudspeaker
R.5-66Z: 400W to 600W @ 8 ohms per loudspeaker
R.5-94Z: 400W to 600W @ 8 ohms per loudspeaker
R.5-99Z: 400W to 600W @ 8 ohms per loudspeaker
R.5-96MAX: 1200W to 1800W at 8 ohms per loudspeaker
R2-94Z: 800W to 1200W at 4 ohms per loudspeaker
R2-52Z: 800W to 1200W at 4 ohms per loudspeaker
R2-52MAX: 1200W to 2400W at 8 ohms per loudspeaker

 

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 for R SERIES loudspeakers can be found HERE.

 

All of the loudspeakers referenced in this guide require a 24 dB per Octave electronic high pass filter for protection against over-excursion from bass-heavy program material.

 

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
Beyond 250 feet: Please contact the Community TAG Team

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.
