Feedback, Artificial Echoes and the Announcer’s Echo

Feedback is unlikely in this system because the loudspeakers are a long distance from the microphone. There’s no chance

of artificial echoes in this design since all the loudspeakers are in one location. Real echoes are possible, of course, so try

to aim the loudspeakers away from any nearby walls or buildings. It’s also possible that an announcer in the press box will

hear an echo of his or her voice. The same problem can occur for an announcer on the field. See Page 9 for ways to

minimize these problems.

Alternate Loudspeaker Choices and 70/100 Volt Systems

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

speakers are available in 70/100-volt versions. Higher-powered versions, like the R1 or R2, can utilize optional (external)

70/100-volt transformers. This makes it possible to use smaller gauge wire to the loudspeaker location which helps re-

duce the overall system cost.

As a lower-cost, alternative design substitute Community’s R1-94Z for the R2-94Z, the R1-64Z for the R2-52Z and an R.5

-66Z for the R.5HP. This alternative design will cover the facility well but will not reach “rock ‘n’ roll” levels.
