10.Internal Crossover – This built-in crossover card is configurable for a multitude of operating frequencies. The orientation of the card in its socket determines the function of high-pass, low-pass or full range operation.

11.Phase Switch – This switch enables you to easily invert the phase without having to disconnect the speaker wires.

12.Crossover Switch – This multi-function switch enables you to select a 12dB per octave slope or 24dB per octave slope of the internal crossover. When switched to 0dB, the internal crossover circuit can be bypassed, maintaining Audiophile sound quality due to a shorter signal path.

13.LED Power Indicator – The LED illuminates when the unit is turned on.

14.Punch Status Display – The RJ11 interface allows connection of an LED display used to monitor amplifier performance.
