ABOUT THE ATTENUATOR

Series Type Stepped Attenuators 
This attenuator is forming by a series resistor which role as a voltage divider.
The rotary switch move through the chain as the volume grip is turned, selecting the output of the attenuator.
The principle is like a potentiometer, the input impedance of the attenuator remains constant, therefore, the signal source will be constant with a non-varying load.


Design by Mr K 59 Step Series Attenuator uses the only top quality component to build.
We use KOA metal film surface mount device(SMD) type of resistor for shortest signal path and very low series inductance and stray capacitance. Gold plated contact point prevents corrosion on PCB even in a hot and humid environment. And precision NMB ball bearing provides the smoothest turn and reliable support.
