I've been using a Zoom H-6 as a USB interface. While it certainly has its features, being an interface is not one of its shining roles.
I started searching for a simple but powerful USB interface whose sole job would be simply being an excellent interface. The more I researched, the clearer it was that the Volt series was what I needed. I received my Volt 2 a couple of weeks ago. Upon connecting it to my laptop and plugging my Shure headphones into the unit, I experienced for the first time what the signal from my Rode NT-1 microphone sounded like.
Whew! Trying to record my classical guitar or simply take part in a Zoom meeting finally sounded as it should. I was beginning to wonder if I needed new microphones or headphones or anything to clear up the boomy, bassy sounds I was getting before through the other interface. I find the Volt 2 to produce an exceptionally clean sound signal that, to my ears, is extremely accurate. I didn't need a huge unit or a lot of extra features. This Volt 2 delivers everything I need and more. I am extremely pleased!
