Commercial Contractor Power Amplifiers

A commercial public address system is expected to operate reliably and without undue fuss. In many installations, PA amplifiers run 24 hours a day, and are expected to deliver critical information when called upon. Some commercial amps perform less demanding tasks like supplying background or foreground music.

Many commercial PA amps include built-in mixers, which make installation and operation super-easy. 70 volt systems offer a simple, cost-effective means of connecting multiple speakers that are sometimes distributed over long distances. Parts Express stocks all of the commercial installation amplifier products, including accessory rack kits, input modules, remote controls, and AM/FM tuners.
