Howdy!
here's a question I'd like a second opinion or angle on. I'm working on a for fun audio project, and here's what I'm looking to do. I want to allow audio from a PC/MP3 player, etc. to be fed into my project as a second option to a microphone built in the circuit. I would prefer to use a switch built into the audio jack to select between the two, as shown below:
In the case where the user has their MP3 player in the second jack and nothing plugged into the first to break the circuit, the MP3 player's output is AC coupled to the Mic.
Would this cause any damage to either the MP3 player or Mic?
Should I add a limiting resistor between the audio jacks and microphone, or look for a different solution for selecting between two audio sources to my project?
