I have tried searching around, and cant seem to find a solution.
I am sending two IC555's to a summing mix output.
At the moment I am outputting the signal in the graph attached (4.2v).
But I do not get a return to 0v. It only returns to 1v and then back to 4.2v.
Is it necessary to achieve a 0v-4.2v output?
If so, how would I achieve this?
I am planning to connect via a unbalanced phono/line input (such as a DJ mixer MIC input/Phono input) or any other means for recording/performing.
Any help on this would be appreciated. Thanks in advance!
PS. I am getting a problem with mixing the two signals together. They seem to blank each other out at the OP amp stage and onwards when I have the mix set to certain settings. (I am using a simulator.)
I can upload voltages/currents or diagrams etc of anything that may help.
I have tried inverted and non-inverted with the same result.
