10.Input Sensitivity Controls – The input level controls are preset to match the output of most source units. They can be adjusted to match output levels from a variety of source units.

11.Internal Crossovers – These built-in crossover cards are configurable for a multitude of operating frequencies. The orientation of the card in its socket determines its function of high-pass, low-pass or full range operation.

12.E-Z Bridge Switch / 0°-180°Phase Switch – This dual purpose switch enables you to E-Z bridge the amplifier or invert the signal phase of the right channel.

13.Phase Switch – This switch enables you to easily invert the phase of the left channel without having to disconnect the speaker wires.

14.Crossover Switching – These internal switches allow the crossover to be distributed to the amplifier and Pass-Thru in many different configurations.

15.Audiophile Bypass – One of the crossover switching configurations allows the internal crossover circuit to be bypassed, maintaining Audiophile sound quality due to a shorter signal path.

16.LED Power Indicator – The LED gives a visual indication of the status of the amplifier, lighting when the unit is turned on.
