PA-6312/6324/6336/6348 Public Address Power Amplifier
PA-6312/6324/6336/6348 are Inter-M’s best-selling commercial PA amplifiers. They are recognized for their ruggedness,
reliability and performance. They are the installer’s choice for sound reinforcement, background music, paging, and public
address systems. Featuring low-distortion, low-noise amplifier electronics circuits which provides a high-output and a high
S / N ratio. PA 6300 series amps provide a wide dynamic range with excellent headroom. An onboard High Pass Filter protects both amplifier and speakers from damaging transients. A comprehensive thermal/electrical protection circuit ensures
long-haul dependability. Thermistor protected output helps ensure overall stability and provides input overload protection.
Internal airflow and exceptionally quiet multi-stage fans ensures amplifier cooling. Phoenix-style terminals provides for
quick, easy hookup. Models are available in a variety of output power, 120, 240, 360 and 480 watts power output in 8/4
ohm low impedance and in 70/100V high impedances output using low-distortion transformers. The PA 6300 series offers
outstanding versatility, long term reliability, and a remarkable value for any installation application.

8. Ground Lift Switch
This switch provides for connection or disconnection of the
amplifier’s ground to AC “earth” ground, to prevent noise from
ground loops. Under most circumstances, this switch should be
set to FRAME position.
9. 24V DC back up power
These terminals are provided for the connection of backup
battery. Connect a 24VDC(100A) battery source to these
terminals. Make certain the red terminal is connected to the
battery’s positive (+) side, and the black terminal to the battery’s
negative (-) side.
