These inputs are for signal cables from the source. Always use high quality RCA cables.
This control allows you to vary the amplifiers input sensitivity between 0.2[200millivolts]and 7.6volts.
Clockwise rotation raises the threshold and lowers the sensitivity, requiring higher input signal voltage
from the source. in order to obtain maximum output. counter-clockwise adjustment lowers the threshold
and raises the sensitivity, requiring a lower source voltage from source unit. The overall objective is to set
this control to closely match the voltage produced by the source unit.
Avoid setting the theshold too low and supplying excessive input signal voltage, as this would saturate
the input stages and introduce unwanted distortion.
Variable Subsonic Filter[10Hz - 50Hz]
The Subsonic filter will roll off all the unwanted frequencies below 10Hz - 50Hz.
This will allow the amplifier to use that wasted power in the audible bandwidth.
