The PA series of commercial power amplifiers is a favorite of installers everywhere for sound reinforcement, background music, paging, and public address systems. Featuring low-distortion amplifier electronics that are bridgeable for flexible power allocation, PA series amps provide a wide dynamic range with excellent headroom. An onboard limiter spares both amplifier and speakers from damaging transients, and a comprehensive thermal/electrical protection package ensures long-haul dependability. Equipped with Phoenix-style terminals for fast, easy hookup, PA series amps are housed in compact, rack-ready 2RU chassis with ample internal airflow and exceptionally quiet multi-stage fans. Models are available in a variety of output powers and channel configurations, several of which provide 70/100V output using low-distortion transformers. Offering outstanding versatility and longterm reliability, the PA series is a remarkable value for any installation application.
