125W/250w/375w/500w/ 70V or 100V or 25V/4 Ohm power amplifier (PA-5125/PA-5250/PA-5375/PA-5500) Thermal protection by muting input signal (typically 85 deg at heat sink) Momentary short circuit protection Dual speed auto cooling fan Manual reset circuit breaker for AC mains and DC input Balanced input signal with gain control and selectable grounding option AC or DC operation for uninterrupted operation during power failure
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.
