  8. Press the record button on the face of the H4n. The ring around the record button will begin to blink. The Zoom is not yet recording, but the inputs are active. This is a good time to make sure you can hear your subject well enough, and that the recording levels are not too high or distorted.

  11. When you are done recording, make sure to turn off the zoom recorder before unplugging the microphones and AC power adapter or removing the batteries.
Note:If you are using a single XLR microphone as your input source, you should make sure you have the H4n is set to MONO MIX. If you are using a stereo pair of XLR mics, or the built in stereo mic, make sure the H4n is NOT in MONO MIX. To change this setting, Press the MENU button, then select INPUT and press the dial to confirm the selection. Turn the dial again to select MONO MIX, and press the dial again. Choose ON or OFF, and press the dial once more to enter in your selection. Press the MENU button until you have returned to the home screen.
Note: Remember that you can always convert a high quality file to a low quality file, but never a low quality file into a high quality file. Suggested file format is 48khz/24bit WAV.
