The RC2 is a remote control for the Zoom H2n and M4 MicTrak that allows you to easily manage and control your recordings. With the RC2 you can use basic recording functions such as start, stop, and pause. You can also play back through files as well as mark specific points on your recording from a distance, thus eliminating handling noise. The RC2 comes with a 1-meter cable and a 3-meter extension cable, both of which make it simple to use your recorder even when you're far from the action.
