Looking for something a bit more “hardcore” than a Zoom H4n? Then check out the Roland R-26 field recorder. One of its most predominant features is its built in 4 channel microphone which includes both omni and directional stereo mics. Channels can easily be adjusted via the dials on the face and you can monitor everything on the large screen. Price is a little higher than the Zoom H4n, but the added features may make it worth the investment.
Roland R-26 6-channel digital field audio recorder
Discovered this few days ago and seriously find it as the best option if you are not on budget, plus the options to grab 6 channels might give a better final audio output, awesome!
