I discovered the 3.9 VDC is called "plug-in" power; typically 3 to 5 VDC. Whereas, phantom power is 12 to 48 VDC. Plug-in power is used by lower-cost condenser microphones, like those connected to the mic input on digital cameras. Phantom power is used by more expensive condenser microphones used for professional recording. Also, a topic I initiated was answered by a "Gold" member who said the microphone port on the rear of the computer is a TRS connector. In summary. The microphone port on the rear of the computer is a TRS connector, and has 3.9 VDC plug-in power. It appears that a condenser microphone that needs plug-in power can be plugged into the microphone port and function as a input audio source. I'll try it out when I receive a budget microphone I ordered.
I want to use a microphone connected to the microphone port on the rear of my XPS 8950. Some microphones are designed to connect to cameras and cell phones as "boom" mics and require a voltage from the device to operate. Does the microphone port on the XPS 8950 supply voltage to a microphone? And if so, how much voltage?
XPS 8950, rear mic port, TRS or TS, phantom power?
