Sound system in a small college auditorium

Abstract

A new two hundred and twenty seats college auditorium needed an electro acoustics system in order to adequately perform all its normal activities which included live voices for lectures and conferences, a sound reproduction system working alone or together with the projection equipment, sometimes background music, and eventually some small groups with live music presentations as requested in the specs of the auditorium usage, it also needed recording capabilities for the most important lectures and presentations. A twelve/eight channel with stereo output system with peripherals was chosen for the installation, where three microphones were reserved for the front table, six distributed in fixed stands located in the aisles of the audience area for questions and dialog, and the other three were movable. Background noise was not an issue because the auditorium is located in a tree full area within the university campus, away from busy streets. Budget for the acoustical conditioning and the electronic equipment was very limited.
