Zoom H2N - Level Adjustments; Adjusting Playback Volume; Adjusting Microphone Gain

Level Adjustments
The Volume buttons are for
turning up or down the
volume for playback
recordings.
The Mic Gain Wheel is for
turning up the sensitivity of
the mic for recordings. Too
much and it can peak and
sound distorted. Yet too
little and you wont hear
anything on the recording.
