DIGITAL AUDIO POTENTIOMETER WITH IMPULSATOR - PRINTED PLATE

Producer: AVT

Potentiometers used to adjust the volume of the audio amplifier often have a scatter of parameters (unevenness of the resistance of the two paths) causing the difference in levels of the audio signal. Experienced audiophiles, in order to avoid these problems, apply a multi-position rotary switch in the place of the potentiometer with carefully selected resistances. Another method to solve this problem is our project built using the perfect MAX5440 system.

Recommendations: the presented device will improve the properties of each audio amplifier.

Basic parameters:

  • Damping adjustment in 32 steps every 2 dB
  • The adjustment range is 0 ...- 62dB
  • Silencing MUTE> = -90dB
  • Constant level -12dB after turning on the power
  • Single supply voltage + 5V
  • The dimensions of the 43x70mm tile

The printed circuit board and documentation are included.
