Bandpass Filter - Dual Pot question

Bandpass Filter - Dual Pot question

2007-03-01 by Andrew

The Bandpass filter specifies a Dual Pot for the frequency control. I
wanted to try using a slider (ala 2600) for this control, and have
some Alpha slider potentiometers that have 4 terminals on them marked
1 & 2 at one end and 2 & 3 at the other.

One pair of terminals (one per each end) gives resistance that goes
from zero to max as the slider goes from left to right. The other
pair of terminals gives resistance that goes max (down)to zero as the
slider goes from left to right.

Is this what a Dual Pot does? And should this slider work for this
control, assuming I wire things correctly?

thanks :)
Andrew

You have a single pot there. The "2" connects to the same thing (the wiper)
at both ends. A dual silder would usally have 4 pins at each end.

So anybody know where I can get "Dual Pot Sliders" ?

I'd really like to make a multi-bandpass with sliders for the
frequency controls...
