LARGE FOOTBALL FIELD #1

SEMI-DISTRIBUTED SYSTEM ON PRESS BOX

DISCUSSION

This is an excellent design for a college or larger high-school football stadium. It combines the best features of a distrib-

uted system (for the home-team bleachers) and a point-source system (for the end-zone and away-team bleachers). All of

the loudspeakers are in one general location which reduces installation costs and eliminates most artificial echoes. If the

electronics rack can be located in the press box, cable lengths are probably short enough to allow use of regular

(vs. transformer) R-Series models which reduces overall equipment costs.

If the roof of the press box is less than about 20 feet (6m) above the heads of the nearest listeners, the R2 loudspeakers

used for the end-zone and away-team bleachers may be too loud in the home-team bleachers. Look for an alternate loca-

tion for these loudspeakers when this occurs. Sometimes, there’s a light pole behind the press box. This makes a good

alternate location for the R2s. Mount the R2s at least 20 feet (6m) above the heads of the nearest listeners (30 feet or

9m is better) and delay the remaining loudspeakers, if necessary, to avoid artificial echoes.

Field Coverage and Neighborhood Spill

This system will have some field coverage from the loudspeakers aimed at the end-zone and away-team bleachers. For

additional field coverage, add R2s at the end-zone side of the press box aimed at the field. R2 loudspeakers are available

in several coverage patterns for this usage.

Colors show sound level variation in audience areas. Field, press

box and other areas will also receive sound (not shown).
