audioguru Posted February 9, 2006 Report Share Posted February 9, 2006 Hi Ana,Didn't you look in our Projects section? Its button is at the top of this page.It has a 3-input mixer that is easily modified for 4 inputs.http://www.electronics-lab.com/projects/audio/009/index.htmlIt isn't high-fidelity but it works.

Um...Me123 Posted May 22, 2006 Report Share Posted May 22, 2006 Is there a way to not use a 10K pot? The site I use for parts does't have 10K! Quote Link to comment Share on other sites More sharing options...
audioguru Posted May 22, 2006 Report Share Posted May 22, 2006 The volume control pots should have an audio taper, not linear.10k is about the most common value for a volume control pot, but a 20k pot will work the same in that circuit.
