QSC grew as professional audio became a major industry. The company's amplifiers became the standard for touring sound companies, installed sound contractors, and broadcast facilities, delivering the reliability, power output, and audio quality that professional use demanded. Today QSC is one of the world's largest professional audio manufacturers.
