1.Input RCA jacks
L INPUT R
These inputs are for signal cables from the source. Always use high quality RCA cables.
2.Gain
GAIN
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.
Avoid setting the theshold too low and supplying excessive input signal voltage, as this would saturate the input stages and introduce unwanted distortion.
3.Subsonic
10
50
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.
