Digital Signal Processors

Live sound requires precise speaker management to deliver the perfect sound. Speakers must be protected and only given a specific frequency band. For example, passive subwoofers generally handle frequencies below 110Hz, any more than this and they lose purpose and could be damaged. In addition to... controlling the crossover frequency delivered to each power amplifier, digital signal processors contain limiters, compressors, and feedback filters to protect valuable power amps and speakers from damage.
