7. 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.
8. Punch Equalization Controls – The Punch EQ helps correct for
acoustical deficiencies in 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.
