The following lines were added (+) and removed (-):
*Simply inserting a stepped attenuator or potentiometer in the signal path without an adequate buffer can lead to serious frequency response deviations due to the RC low-pass filter effect of the passive's output impedance and any cable capacitance.*Simply inserting a stepped attenuator or potentiometer in the signal path without an adequate buffer can lead to serious frequency response deviations due to the RC low-pass filter effect of the passive's output impedance and any cable capacitance. The lower you go with the volume setting, the narrower the bandwidth becomes right in the audio band.  ----
