This recorder is not only great for recording each student on an SD card in class, it's fabulous recorder for our video shoots as well. Capable of 6 channel recording and with various accessories from a very good shotgun mic to 2 extra XLR inputs. The new LED color meters on the front and separate gain control dials by each iput makes this one of my favorites.
