25K 24 Step Ladder Type Stereo Volume Attenuator

Advantage of Ladder Type Volume:

• In Ladder Type volume control, input signal only pass through two fixed resister at a time. Hence noise introduced is much reduced compared with other type of configuration such as serial type. Although serial type stepper volume  is simpler to construct, input signal has to pass through many resistors, noise is thus accumulated.
  　
• Ladder Type volume control eliminate the problem of low accuracy, low stability, poor channel matching, high noise .... in traditional potentialmeter (variable resistor -VR) used in general audio equipment.
