Altoids Tin 1/8" Stereo Mixer using a 3.5mm 4 pole conductor (mic + audio)? Answered
Hey have been thinking on how to modify https://www.instructables.com/id/Altoids-Tin-18-Stereo-Mixer/ to accept a 3.5mm 4 pole conductor as the output while splitting the mic to the inputs. This is going to be something like the Iphone ear buds with built in mic. I just got a pair of amplified 4 pole headphones with mic that I want to use for everything. Here is my wish list:
3 - 4 pole Audio in (iphone, macbook, ...)
1 - 3 pole Audio in from computer
1 - Mic in from computer
1 - RJ10 (so I can use my headset with my cisco phone)
The audio mixing is basically the same as Rich's write up. But im not sure if I can just split the mic to everything. If I am sacrificing mic volume by splitting to every input I could limit it to the CPU mic and the RJ10.. the ones i really want.
Please let me know any ideas or advice you have.
Here is my purposed schematic:
