There's been more than a few times I wished my Zoom H4n had more than just two XLR inputs. The new Zoom H6 portable digital audio recorder solves this problem and also brings a new modular Microphone design, or the ability to add another dual XLR/TRS input through the top of the recorder.
I'm really hoping this new H6 has better gain than the H4n as well. The H4n was a great recorder, but couldn't provide enough gain on some of my more expensive microphones. The new Zoom H6 was announced a few months ago, but is finally in stock today at (B&H) Click here.
