Hello. I want to do some scans of my room. I was looking into a mini DSP. I do a lot of recordings for business so I have active, passive, cardioid, super cardioid, and omni directional all types of mics most with XLR connections because all even half descent professional mics use XLR not USB. My mics cost 4 - 7 times more than the UMIK 2. So my question I had a call with this guy, self-proclaimed expert that sells gain matching services told me that the UMIK 2 was the best and absolutely required but this same guy didn't know what XLR or an audio processor even was so this makes me suspect of his "expertise". I'm new to the REW world but very knowledgeable about AV recording equipment, so good chance he could be right, but his presentation raised potential red flags for me. I just don't want waste money paying for an Uber when I already own a bunch of cars if know what I'm saying.
