how to create a tone control

[.ALJ.jun]

i want to create a tone control that only ranges from 40hz-80hz only.

is this possible??

Well ya.
Do you know how to make filters?

 

[alec_t]

Is that band pass or band reject?

 

[crutschow]

What exactly do you want the tone control to do?

 

[aljamri]

Using Micro Controller ?

If you can't answer my question, I can't answer yours.

I think we've lost the OP.

Johnny come lately, He has no activity since the initial contact Saturday morning.
Reminds me of some of the urgent requests for help from newbies never to be seen again.

i know how to create bandpass

but my problem is how i connect the potentiometer in the circuit

i only want to use capacitor and potentiometer

"a tone control that only ranges from 40hz-80hz. is this possible?"
"i know how to create bandpass"
I'm confused. Those statements don't seem consistent. If you know how, why are you posting here?

"i only want to use capacitor and potentiometer"
All the band-pass circuits I've seen require more than a capacitor and a pot. How do you manage it?

What circuit????????????????

this is my diagram

i want to now the value of my capacitor for 40hz-80hz bass control

Seems to be a variation of a baxandall tone control circuit.
Maybe this will help;
