- jbverschoor 5y agoThe new MacBook Pro even has automatic phantom power
- nitrogen 5y agoNice. I feel like that used to be common for PC microphone ports that were separate jacks, but IIRC it was at a much lower voltage than the 48V professional phantom power.
- jabbany 5y agoThis never really got "replaced" though. All the new connectors are for digital connections. There's not much new for analog, which is probably the way it should be.
- tzs 5y agoUSB-C has a mode called Audio Adapter Accessory Mode. In this D+ and D- become right and left analog audio output, respectively, and SBU1 becomes analog microphone input. Here's a reference design from TI showing how one might implement it on a device where you want to be able to switch between using your USB-C connector for data devices and for analog audio devices [1].

- postalrat 5y agoThere won't be much new for analog until something lower level is found.
- romwell 5y ago> All the new connectors are for digital connections. USB-C headphones might disagree with you, as the other comment has pointed out (USB-C supports analog audio on data pins in order to create the one-connector-to-rule-them-all).
