While it lacks some of the basic features, such as XLR inputs found on my other recorder, the Zoom H4n, the cool thing about the H2n is that it has a lot more mics built into it as preset configurations. The four main recording modes are Mid-side, X/Y, 2-channel surround and 4-channel surround, and each of these can be tweaked further for greater/lesser stereo width. This means that it's a really useful recorder to grab spontaneous recordings with when I'm out and about, without having to lug around a bunch of extra stands, cables and mics with me on the off-chance I find something interesting to record.
The slight drawback I've encountered with the unit so far is that the surround sound recording capabilities are not as good as I was hoping for. The H2n can record to a max sample rate of 96kHz and to 24-bit depth for the mid-side, X/Y and 2-channel blended surround modes, but if you want to make a discrete 4-channel surround recording, the device can only record to 48kHz/24-bit. Though 48kHz is the post-production standard sample rate, it would have been nice to be able to record at max quality to make it easier to pitch-shift your recordings without introducing a load of unwanted artefacts into your sounds.
Still, I'm having a lot of fun using the H2n as my go-to stealth recorder. Time to slink back into the shadows and find more things to record!
