I am using a 5532 op amp for a small mixer to mix two keyboards for live performance. I know the op amp is desgned/compensated for unity gain.. One of the key boards out put is quite a bit greater than the other so I have been using a feedback resistor 5 to 10 times the the resistors on the inputs for 5 to 10 gain. It works pretty well but I now get distortion fron the hotter keyboard if I turn it up much. I am new to the site and could not get a diagram to upLoad as the buttons were greyed out but I took the design frm Craig Anderton's Electronics Projects for Muscians which a lot of People seen familiar with.
Is there an easy way to get more gain without this distortion? I can work around it but would like to know how to fix this.
