I bought a Zoom H2n used pretty cheap (haven't received it yet.) This looks like a very versatile product. I don't know that I will bother connecting it to my Surface, other than for testing. The only real benefit I can see from that is that the Surface would be like a remote control and I could see the signal levels clearly while recording. But it may not be worth the trouble, as easy as the Zoom recorders are to use.
One thing that slightly troubles me is that Zoom doesn't quote frequency specs for their Zoom capsules. Somewhere I saw somebody state them as 70-18,000. If there is a big drop-off under 70, that would be missing a lot. I notice the Yeti Pro is quoted as 20-20,000.
I have the Zoom H6, which I believe use the same capsules that are in the Y4n and Y2n. I know I get lots of sound below 70 Hz, but I don't know how it tapers. In practice, I mainly would look for bass trombone or tuba, so 45 Hz is about the bottom for me. I expect there will be enough to pull it up with EQ. If it is a big problem, my plan B will be a Yeti Pro.
Can anybody provide any practical guidance about the "2-channel surround" (which seems like an oxymoron) and the "4-channel surround" on the H2n? I assume that "2-channel surround" simply means that we pick up 360 degrees of sound, but present it as stereo with clear left-right separation.
