this passive attenuator uses a precision resistor that is connected in parallel with a 1% SMD mechanical resistance 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 resistance R-In that determines the minimum input impedance when the potentiometer is in position 0. Both passive preamplifier and source selector, this device with its Aluminium and wood finish will convince. It is equipped with very high quality components assembled by hand with the greatest care. In addition to its magnificent design, this volume controller features the latest technology in this field.
