I would like to create this circuit:
Link to the Circuit
however, I have a bunch of questions:
how does one create a rail (basic circuit 101, right? I assume this can be created by basically soldering the power line to a open uninsulated copper wire of some sort...)
where the microphone is, I plan on using an electret microphone (despite the author saying not to use VOIP headsets, I plan on doing so). is it ok for me to use both the ring and tip in the trs format for "1" and "2" as sleeve? (i.e. combining both tip and ring to form one line versus 2)
I have a little problem completely understanding how the microphone amplifier output can be completely nulled. I understand the usage of the DPDT switch, however, I feel that I can't picture not hearing myself thru the headphones despite the switch being there.
lastly, the "resistor across the wiper" - they said that value (10k) can be improved. If i were to use 50k pots or something around that, what value would you recommend for the resistor?
p.s. i plan on using a 3 pin xlr (not using the program audio, using the microphone output as a second input to null it out [see question 3]) so, does that work out too?
Thanks for all the help, if anyone replies lol. I feel like what I just posted was too much
*also attached the pdf
