This Khozmo Acoustic passive attenuator uses a resistor connected in parallel with a 1% SMD resistor mechanical switch. This resistor is connected to the potentiometer, which, depending on its position, more or less connects the output to ground and thus varies the volume. It is therefore the R-In resistor that conditions the minimum input impedance, when the potentiometer is on position 0.

Both passive preamplifier and source selector, this aluminum and wood finish unit will surely convince you. It is equipped with very high quality components assembled by hand with the utmost care. In addition to its magnificent realization, this volume controller has the best technical features.
