LARGE FOOTBALL FIELD #2

POINT-SOURCE SYSTEM AT END ZONE

DISCUSSION

When you can cover an entire facility from one location, a point-source system is an excellent choice. In this example,

we’ve covered all three sets of bleachers from the end-zone using only four R-Series loudspeakers. The equipment cost is

similar to the previous distributed system and the design is easy to expand for coverage of an opposite end zone bleachers

or the field itself.

Feedback, Artificial Echoes and the Announcer’s Echo

There’s little chance of feedback in this design because the loudspeakers are a long distance from the announcer’s micro-

phone. There will be an announcer’s echo for announcers located in either the press box or on the field. See Page 9 for

a discussion of these problems.

Field Coverage and Neighborhood Spill

This design provides some field coverage. To improve field coverage, add additional R6-51s. Mount the loudspeakers as

high as possible and aim them down at the bleachers and field to minimize neighborhood spill.

Colors show sound level variation in audience

areas. Field, press box and other areas will

also receive sound (not shown).
