QSC Audio Products, Inc. is a globally recognized leader in audio manufacturing of power amplifiers and control systems.

On a hot, summer day more than 30 years ago, Barry Andrews' motorcycle broke down in an industrial park in Costa Mesa, Calif. While waiting for a friend to pick him up, Barry struck up a conversation with a guy working in a nearby garage. His name was Pat Quilter.

Pat talked about his fledging business - designing and building various types of amplifiers. Barry, who worked as a cabinet woodworker at the time, had experience building speaker cabinets. Eventually, Pat decided he needed some extra help building wood audio cabinets.

It was a move that laid the foundation for a company that would become the world's largest manufacturer of professional power amplifiers. Pat Quilter's small company, Quilter Sound Company, would eventually be incorporated as QSC Audio Products, Inc. and become a major player in the professional audio industry.

QSC products have a reputation for quality, innovation and reliability. Exceptionally high value of QSC’s products is achieved through developing leading technologies, world-class manufacturing techniques, and the purchasing power possible as the world's leading amplifier producer.

While QSC continues to set the standard for amplifier technology, the company has also made significant strides in computer control, digital signal processing and signal transport. QSControl, a remote audio monitoring system application, has proven its performance in systems worldwide.

QSC changed the face of amplifier technology with the introduction of QSC's exclusive PowerWave(TM) switching power supply, a technological advance that makes heavy, bulky and inefficient amplifiers a thing of the past. PowerWave(TM), first incorporated into the revolutionary PowerLight Series and now used in three other amplifier lines, is proof that high power can be achieved in small, lightweight packages.
