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 V/100 V output using low-
distortion transformers. Offering outstanding versatility and
long-term reliability, the PA Series is a remarkable value for
any installation application.
