    100V - 240V 50Hz/60Hz 1A The LIMIT LED will illuminate when the PA40G/PA60G is in a clipping condition, caused by excessively high input levels or a GAIN control is turned up too high. An occasional flash is OK. Check that the proper signal level is being fed into the inputs and/or turn the input gain down until the LED is no longer illuminated.

  • Page 7: Wiring The Pa40G / Pa60G

    Balanced line level signals connect to the (+), (–), and (G) terminals. If you are connecting an unbalanced line level input, tie (short) the (G) and (–) terminals together. If transformer isolation is required for Input 1, contact Atlas Sound for details. Note: The Balanced Line Input and the Unbalanced RCA Inputs are electrically isolated from each other and can be used at the same time.

  • Page 8: Limit Led & Load Considerations

    Security Cover Rack Mount Kit Options The PA40G & PA60G can be rack mounted as a single unit or with two units together. To do so a PA702RMK Rack Mount Kit needs to be purchased from Atlas Sound. Limit LED and Load Consideration If the Red Limit LED illuminates, the amplifier has sensed an improper load or the input signal is too high, triggering the protection circuitry.
  • Page 9 Measuring Speaker Loads Below is an Impedance load chart for the PA40G and PA60G. Measure the load impedance prior to connecting the load to the amplifier. The enclosed load chart will provide the information to determine if the load or speaker system impedance is too low for the amplifier’s rating.
