Systems for Stereophonic Sound Reinforcement: Performance Criteria, Design Techniques, and Practical Examples

摘要

Although stereo systems for large rooms were pioneered in well documented work at Bell Labs in the 1930's [1,2, 3, 4], most modern practitioners appear to be ignorant of the most important aspects of that work as applied tomodern sound reinforcement. This paper draws on the author's experience over nearly twenty years with bothportable and permanent systems using two and three front referenced channels. Design criteria and examples arepresented to illustrate both good and bad design practices, and some important pitfalls are noted.
