I'm not sure you can help as you've gone through this cycle of dangling assistance and then becoming a dick twice(?) now. This thread must be important to you (as you've been here three days in a row) so feel free to continue alluding to how helpful you could be if you had people skills and/or lacked personality disorders.Im sure i could have helped you overcome your problem but unfortunately you are not able to converse effectively as to what you want both circuits to do to the signal.
Im afraid i wont be able to help you further,
Good luck with your circuit!!
thanks
The OPamp is a NE5532P.Why can't you post the complete circuits with part numbers like everybody else does?
I use Microsoft paint program to copy whole schematics or parts of them then paste them together. Straight lines are easy when the Shift key is held down. I can easily type part numbers onto a Paint schematic.
I suspect that your "amplifier" in the second part is an LM386 little power amp that has internal biasing and internal negative feedback and its inputs work fine at 0V.
Oh, awesome. I think I'll try the first option and see how that works.Ok, you have two options in this case.
1. Use another opamp in place of the transistor stage.......
2. Put those 2 resistors I showed you in the pic on the opamp input......
That's it. Let me know what happens.
Would running a quad-opamp floating work?An op amp won't work unless the power supplies are returned to signal ground. A floating power supply will not work.
If a floating power supply for one won't work, why would you think it would work for two, or four?Would running a quad-opamp floating work?
Using 2 for one circuit, 2 for the other?
I have circuit two working now with a floating power supply and it has 2 opamps in it. If a quad opamp were used instead it should work as well (I think.)If a floating power supply for one won't work, why would you think it would work for two, or four?
What is the part number of your dual op amp?I have circuit two working now with a floating power supply and it has 2 opamps in it. If a quad opamp were used instead it should work as well (I think.)
I have to dive a bit more into my single supply opamp readings. I'm over my head.
I think I solved it!!...Is there a way to make the circuits works together? Daisy-chaining, or power conditioning, isolating, coupling...
That is awesome! My next tattoo.I think I solved it!!
It's a texas instrument NE5532PWhat is the part number of your dual op amp?
You might think it's working, but I don't.I have circuit two working now with a floating power supply and it has 2 opamps in it. If a quad opamp were used instead it should work as well (I think.)

Depends how liberal you are with the word "working."You might think it's working, but I don't.
If you post a real, complete, accurate schematic, I 'll tell you why I don't think it is working.
Otherwise, I'm outta here.
Wow. You wouldn't believe how many circuits I have built that changed the signal, but didn't work (don't ask, I lost count).Depends how liberal you are with the word "working."
It's definitely changing the signal.
