Behringer potentiometer

[Demon]

Heads up to the next guy that looks at these taper B 10K pots.

They are not completely straight linear, they have a slight curve at the 25% and 75% curve.

They are between the taper B3 and B4 on page 4:

These are NOT taper B1. They sure are smooth though.

Why would one need such a curve?

Audio mixers use them. Something about how the human ear works.

[Ioannis]

Any audio volume control will use logarithmic curve. Any tone control and balance uses linear as far as I know.

A mixer should also use log curve since it controls volume.

I don't know.

I bought a bunch of those Behringers thinking linear meant linear.

Apparently I was wrong. Sometimes it means "nearly" linear.

[Ioannis]

Is it a serious problem for your project? If yes, maybe you can calibrate it with software.

It is. People expect engine rpm to rise with throttle input.

I could, but I shouldn't have to. I'm waiting for a reply from bourns on an ordinary linear slide pot.
