OVERVIEW OF THE FRONT PANEL
In the center of the front panel is the volume control knob. “GAIN”knob is used
to control damping and to turn on the „MUTE” function.
Switching the function is caused by turning the knob to the right (gain increase at
discrete intervals) or to the left (gain decrease at discrete intervals).
Gain regulation changes the sensitivity of the preamplifier.
It is particularly useful when using modern sources with high input signal (CD,
DAC). Available input signal damping settings:
„MUTE”, „-12 dB”, „-6 dB”, „0 dB” (no indication from any signaling diode).
Every change of setting causes a temporary muting of the ASP-1000 output.
