APPLICATION GUIDE

6.3 High School Gym

This installation example refers to a sound system for a multipurpose gym with some stands to be used in case of
special events. The system is mainly used for paging inside the school, alarm/evacuation messages, background
music and anthems before matches or tournaments

Speaker Layout

Given that the available rigging points are under the vault, the speakers will be installed there and oriented to-
wards the stands and the field for a complete and uniform coverage. For this kind of environment we choose
~98dB as a target for the direct SPL in the vocal range of frequencies (400Hz-4KHz). We choose to use 8 x P3115
to have enough SPL, to properly cover all the space (in such a highly reverberant environment intelligibility may be
critical especially if we use a too centralized system) and to exploit 100V distribution if required.
