Hi everyone. Let me start off by saying that I am a hobbyist when it comes to electronics so hopefully this question won't sound too stupid. In a little audio project I am working on, I am using two opamps (one dual opamp actually) as buffers for incoming audio signals. I want to blend the output of the two opamps using a 100K pot and then "feed" that blended signal into a third opamp. Will that work like I am expecting or are there any concerns that I don't know about?
I've seen circuits where the output of an opamp goes directly into the input of another omamp (some bandpass filters for example) but is this any different because the signals come together in a Y and there are two paths for a signal to take? Because opamps have relatively high input resistance (about 2M ohms typical in this case) and a low output resistance (about 75 ohms), is it possible that the signal from one of the "input opamps" will affect the other? Or is that never much of a concern?
