Description
 
The PA-5500, PA-5375, PA-5250 and PA 5125 are reliable, heavy-duty single-channel power amplifiers designed for demanding sound system applications. All models feature an XLR balanced input, with adjustable input sensitivity from -40 to 0dB. A parallel male XLR connector enables convenient amplifier linking in multiple amplifier installations. Automatic thermal protection circuitry is provided and an "idling" circuit protects against thermal runaway. A two-speed fan helps ensure reliability, switching to high-speed when the amplifier is under heavy load. Front panel LEDs indicate output levels of -40dB, -10dB and clipping, as well as protection circuit activation. A ground-lift switch is provided to isolate signal ground from chassis ground. The outputs are 4 Ω, 70V, or 100V. The units can be powered by 220 - 240VAC or 24VDC, enabling the unit to be used as part of a portable PA system, or connection to a standby power supply for emergency operation. All models are packed in a 3.5" high (2 RU) rack-mount enclosure.
