Inter-M Americas Inc PA2312

The PA-2312 is a reliable, heavy-duty dual-channel public address amplifier designed for demanding sound system applications. The unit features XLR balanced inputs with front panel-mounted signal level controls. Parallel male XLR connectors enable 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. Switchable high-pass filters help provide low frequency protection for speakers. 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?, 70V, or 100V (output transformer varies depending on country). The units can be powered by 100-120VAC/ 220-240VAC (depending on country requirements), 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. The unit is packaged in a 5.25" high (3RU) rack-mount enclosure.
