DIY mixer first project

[Bananasdoom]

I want to build a basic stereo mixer for my pc, so I found this indestructible that has resistors in between each source and that got me wondering if I could use a dual pot instead and have control over the input volume. Maybe I can use this for a multi mic setup. What pot should I use and will my idea work?

You can have dual pots as it is stereo.
Look up dual pot at any electronics supplier.
RS Components | Electronic and Electrical Components
Maplin Electronics : External Hard Drives | Music | CCTV
Farnell United Kingdom | world-leading distributor of electronic and maintenance, repair and operations products.

you should put the pots across the input of the mix matrix.

a 10k pot should be good enough for your applications.
