Hello! I'm new to the world of op amps and I'm a little confused on how to power them properly. I'm planning on using the TL072 as an audio buffer for a reverb circuit. One half will be used as an input buffer before the digital reverb chip and the other half will be used as an output buffer. I have seen in other circuits that if I use a voltage divider on the signal input, it should work properly. My question is, if the signal input is different on the second half of the op amp (i.e.. after it has been processed by the digital reverb), will I still need to create a voltage divider network on the slightly different signal?
Here's a link to the circuit I'm planning on building: http://www.accutronicsreverb.com/design ... /img08.jpg
I realize that I could always build something that's been built and verified but I thought I would take this as an opportunity to learn about the ins and outs of the effects that I use.
