I have a mic with an unusual pin config for its output. I want to buy an adapter so I can use it with my new camera, phone, or laptop but I can't seem to find the right one. For further context the pin on the right is your standard 3.5mm Tip, Ring, Sleeve and the pin on the left is built to provide external power. I got the mic off of an old Canon XL1,the camera is so old it was the only piece of value. If you have a link for the adapter (preferably amazon) please let me know. But any info is useful, thanks!
Edit: it looks the same as a walkie talkie plug. Are there walkie talkie adapters for computers?
