2 R2-94Z For coverage of the far areas of the home-team bleachers

2 R1-94Z For coverage of the near areas of the home-team bleachers

3 R2-52Z For coverage of the end-zone and away-team bleachers

12 R.5-94TZ For coverage of the home team bleachers center areas

Based on cost comparison scale: $ = lower cost, $$$$$ = higher cost

System Cost Estimate - $$$$$

There will be some neighborhood spill behind the end-zone and away-team bleachers. To minimize this problem, mount

the R2s covering the end-zone and away-team bleachers as high as possible and aim them down at the bleachers. Delay

the other loudspeakers, if needed, to avoid an artificial echo.

Feedback, Artificial Echoes and the Announcer’s Echo

This type of system should not produce artificial echoes. Real echoes are still possible, of course, so try to aim the loud-

speakers away from any nearby walls or buildings.

An announcer in the press box will be near the loudspeakers and should not hear an artificial echo. If feedback is a prob-

lem, teach the announcer to close-talk the mic or just shut the window. An announcer on the field, however, will hear a

confusing “announcer’s echo”. See Page 9 for ways to minimize this problem.

As a lower-cost, alternative design, substitute Community’s R.25-94TZ for the R.5-94TZ. This loudspeaker will cover the

press-box audience areas well at a lower level than the R.5-94TZ.

Alternate Loudspeaker Choices and 70/100 Volt Systems

Add R2SUBZ loudspeakers for extended low frequency response. Most Community R-Series and WET Series loudspeak-

ers are available in 70/100-volt versions. Higher-powered versions, like the R2, can utilize optional (external) 70/100-volt

autoformers. Use these transformer-coupled versions if the electronics rack is in a remote location.
