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.

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
