8.Input Sensitivity Controls – The input level controls are preset for 500mV which will match the output of most source units. They can be adjusted to match input levels ranging from 150mV to 3V.

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

10.XCard (Internal Crossover) – These built-in crossover cards are 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.
