8 R2-77Z For coverage of bleachers

2 R.5COAX99 For coverage of concessions (use delay to synchronize with main loudspeakers)

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

that, in competition gyms, the designer must often comply with sports regulations that may force the loudspeakers to be

at or above the ceiling girders.

Simplified Distributed System (not Suitable for Multi-Purpose Use)

This design has a row of loudspeakers aimed at each set of bleachers. This design is simplified from the previous design

because there are no floor-coverage loudspeakers. Because of the lack of floor coverage, this design is less suitable for a

multi-purpose gym. However, it may be a good option for a competition gym that is only used for sports. Musical sound

quality will be excellent. Voice intelligibility will be very good but not quite as good as the previous example which had

the loudspeakers closer to the listeners. Note the R.5COAX99 loudspeakers that cover the concessions area. Use delay

to synchronize these loudspeakers with the main loudspeakers.

Alternate Loudspeaker Choices and 70/100 Volt Systems

The R2 loudspeakers used in this example are high-power devices that can easily produce “hip-hop” or “rock ‘n’ roll”

levels in large gymnasiums. When level requirements are lower, substitute the Community R1-66Z for the R2-77Z. The

R1 loudspeaker series offers excellent pattern control at a lower price.

Add R2SUBZ loudspeakers for extended low frequency response when students want “rock ‘n’ roll” musical performance.

Note the position of the optional subwoofers in the diagram on the opposite page. Locating the subs directly over the

audience allows them to be operated at a lower level which reduces the room reverberation.

Accessory 70/100-volt transformers are available for R2 loudspeakers. However, if wire runs are short enough, it may be

possible to eliminate the transformers and reduce the system cost. Choose amplifiers that are rated for the resulting low

impedance load.
