Our R&D responsed Taper A will go up exponentially, and taper B will go up slowly at first and faster in the middle and will go slowly again in the end.
So do you think it is better to go up exponentially?
When designing an audio amplifier, it is generally recommended to use a volume potentiometer with a logarithmic (also known as audio taper or type A) taper. This is because the human ear has a logarithmic response to sound pressure level, so using a logarithmic taper potentiometer allows the volume control to have a more linear response when adjusted.
On the other hand, a linear taper (also known as type B) potentiometer would have a linear change in resistance as the shaft is turned, which would not accurately mimic the response of the human ear to changes in volume. This can result in a volume control that feels uneven or non-linear to the user.
It is worth noting that some applications may require a linear taper potentiometer, such as when a precise, evenly spaced adjustment is needed, or when the potentiometer is being used for a purpose other than volume control. In these cases, a linear taper potentiometer may be more appropriate. However, for most audio amplifier applications, a logarithmic taper potentiometer is the preferred choice.
Again, all these need to be lab tested. The crossover frequency should be accurately marked on the product. Maybe the pot value isnt adapted correctly.
