1 WHA T IS A SPEAKER MANAGEMENT SYSTEM? A Speaker Management System uses digital signal processing to accom- plish multiple functions that affect the audio signal between the mixer and the power amplifiers. These functions include crossover , equalization, delay , limiting, high-pass and low-pass filtering as well as signal distribu- tion. Programs[...]
