No, the line inputs do not have phantom power. Because TRS connectors are often wired many different ways for different applications, it is rare to see a TRS connector on a capacitor microphone. Think about it, that connector is used for balanced input, send and return on effect units, stereo headphones, Y-cords, and more. You can imagine the risk to equipment if 48V was applied incorrectly to these devices in many of these cases. Fortunately, XLR connectors are primarily used in audio for balanced microphone cabling. I’m not saying these connectors are not used for anything else, but it’s rare. So, you’re actually better off, and your capacitor mics safer from damage, if you do replace their TRS connectors with XLRs.
