PA-9312 / 9324 / 9336

Power Amplifiers
Features Description
The PA-9312, PA-9324, and PA-9336 are reliable, heavy-duty single channel power amplifiers designed for demanding commercial and professional sound system applications. Both models feature an XLR balanced input, with adjustable input sensitivity from -12 dB to 0 dB, and a parallel male XLR connector enables convenient link hookup in multiple amplifier installations. Automatic thermal protection circuitry is provided and an automatic idling circuit protects against thermal runaway. Two-speed fan cooling ensures reliability, switching to high efficiency when amplifier demand is at peak operating levels. A switchable high-pass filter provides driver protection from excessive low frequencies. Front panel LED’s indicate output levels of -40 dB, -10 dB and clipping, as well as protection circuit activation. A ground lift switch is supplied to isolate signal ground in case of hum or ground loop problems, and the output is selectable for 4 ohm, 25 volt or 70 volt operation.

The PA-9312, PA-9324, and PA-9336 are powered by 115VAC @ 60 Hz and/or 24 VDC, enabling its use as part of a portable P.A. system, or connection to a standby power supply for emergency operation. All thre units are packaged in a 5 1/4" high triple-space rack-mount enclosure.
