7.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.

8.Punch Equalization Controls – The Punch EQ helps correct for acoustical deficiencies of the listening environment. The Bass control allows a narrow band adjustment of up to 18dB centered at 45Hz. The Treble control is a wide band hinged adjustment with a maximum of 12dB at 20kHz. The Punch EQ can be bypassed by turning the controls to their minimum or counterclockwise position.

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

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