For an xlr mic you would want an audio interface sorry for the confusion. You can pick one of those up seperate and some are fairly cheap. Right now with the state of the economies and everything being closed getting an audio interface cheap could pose a bit of a challenge as I would normally recommend a behringer um2 audio interface for your generic cheap go to interface (these are normally like $30-$40) but finding those and others is tough since the prices are hiked right now. Others here would know more on that particular setup. Outside of the microphone and possibly an interface yea. You should have everything you need already. You could, for example, use one of those keyboards with a usb port on them for some microphones so it won’t go to your computer these are called “usb passthroughs” kinda cleans up the clutter. Otherwise IIRC the modmic uni can connect to the console controllers instead of usb and the modmic wireless is a usb dongle so those are options. Audio interface um2 https://www.adorama.com/beum2.html?gclid=EAIaIQobChMI2PyW1c606QIVh7zACh1YOAe5EAYYAiABEgJ2A_D_BwE&utm_source=adl-gbase works fine not the greatest will work for the lower ended microphones… if you want over $150 microphones though you will want a better interface. May find this audio interface cheaper elsewhere and will require some research. The UM2 does it’s job its nothing spectacular and is solely for use to a cheaper budget xlr microphone setup. You may find more information on microphones from my old subject I had created Microphone advice? which is where I first began looking into usb/xlr/modmic etc Feel free to chime in on that post or find other posts like that on the forums here if you wish to learn more… If the others see it I am sure they can be much more help than I can when it comes to microphones of the XLR category
