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.

Point-Source System

A point-source system is usually the lowest-cost option for any facility. The point-source system in this example will pro-

vide ample level and excellent musical sound quality with good voice intelligibility. In comparison, the Ceiling Distributed

design (High-School Gym #1) will provide better voice intelligibility and more flexibility for multipurpose use at somewhat

higher cost. Note the R.5COAX99 loudspeakers that cover the end zone area. Use delay to synchronize these loud-

speakers with the main loudspeakers.

Multi-Purpose Usage

The four center-mounted loudspeakers will provide adequate floor coverage for pep rallies but this system is not designed

for uses where an audience is sitting in chairs on the floor.

Alternate Loudspeaker Choices and 70/100 Volt Systems

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

gymnasiums. When level requirements are lower, consider the Community R1 loudspeaker series which offers excellent

pattern control at a lower price.

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

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. This example also shows an optional pair of R.5 loudspeakers used to cover end-zone seating.
