I did not download a schematic for the VTB1 but Sweetwates shows specifications as Switchable Impedance between 50/200 Ohm which would not work for a 600-ohm mic.


The specs on Sweetwater don't tell the full story, the actual impedance used is different than the specs you observed.
From the manual (http://studioprojects.com/pdf/vtb1_manual.pdf)page 3
"Mic Input (Rear switch in 200 ohm position): 2000 ohms
Mic Input (Rear switch in 50 ohm position): 300 ohms"

So with the switch at 50 ohm position, it yields 300 ohm .. not sure why there is a difference in this, which is why I asked.
I am NOT an electrical engineer type guy (I don't even like soldering, except for stuff like copper pipe; my electronics soldering has always ended dismally)
To me the VTB1 makes both my LCD and my SM57 sound better than the Focusrite or other devices.
I was honestly asking if this may be why ..
In other words, my original question wasn't meant to be rhetorical, but rather quizzical in nature so I can learn more, so I asked
.. and yes the VTB1 does have an adjustable amount of tube added (12AX7 that can be replaced with a non-stock one), so it becomes more complicated at that point
It allows hybrid tube/solid state mix

My usual setting is about 40% tube, and I have no idea if this would increase/decrease the end result impedance, like I said it gets complicated, but I do like it and wonder if there is a empirical explanation
Never looked for the schematics, but I'm sure they are out there .. they would mean absolutely nothing to me

I do not work here, but the benefits are still awesome
