I was thinking about doing this, hopefully someone one CraigsList will pick up my USB Samson C01U. I know nothing about XLR mics. How would I hook this up to my PC? Is there an affordable option? I'm assuming the device
used to hook your mic into is also a USB device?
Yea it still uses USB. Also, I'm not an expert, just to add a grain of salt to any advice I'm about to give...
First get yourself an XLR microphone. The nice thing about xlr is there are a lot more options in microphones than USB (at least from my experience).
I'm just going to assume you are going to be using this for stuff like podcasting and nothing too fancy.
If that's the case, once you have your mic, choose an "audio interface" with a built-in preamp. Forgive me for the boring tech jargon but all this stuff can be bought as separate units and I didn't want it sounding like they are all the same. You need the
preamp to boost the mic signal so that you can hear it. USB condenser mics usually come with preamps built into the mic itself.
Anyway, my current setup is an AT2020 xlr connected to a Focusrite Scarlette 2i2 audio interface. That is then connected to my computer by USB 2.0. My desktop speakers are connected to the focusrite's headphone port with a 1/4" TRS adapter.
Total cost:
I got the mic in a bundle that came with the mic, a pop filter, and xlr cable for $109.00 from Amazon and the interface ran
me $150.00
There are cheaper interfaces and microphones so don't think this is what you have to spend. Definitely some low-budget gems out there.
Important note: if you are using a condenser microphone make sure that whatever interface you get has 48volt phantom power. Phantom power just means that the USB port powers your interface and the interface powers your mic. Condenser mics
need 48v or they don't work.
Before I knew about the 48v I bought a Behringer Xenyx302 USB. Cost me $50.00 but could not produce the necessary power requirements for the mic and caused it to kill in and out. Also produced a lot of static pops and noise and I ended up returning it to
Amazon, so I'm going to recommend buying your first interface from an audio store instead of online.
I got my focusrite from a Guitar Center, it was the exact same price as Amazon and I was able to talk with a sales person who knew a ton more about audio than I ever knew existed. Anyway hope that helped.
