Before Filming
Before filming, ready the camera as described below.
●Sound
The D4 supports the following sound recording features.
External Microphones
The optional ME-1 stereo microphone can be used to re- cord sound in stereo or to avoid recording lens noise dur- ing autofocus. To reduce low-frequency noise, including that produced by the wind, rotate the low-cut filter switch from FLAT to L-CUT. Note that noise from the switch may be recorded if the control is operated during filming.
Headphones
Third-party headphones can be attached via the headphone connector so that you can check sound during filming. Note that headphone and microphone settings can not be ad- justed during shooting; before recording, check headphone volume in the live view display (page 55) and adjust head- phone volume and microphone sensitivity as necessary.
Microphone Sensitivity
Microphone sensitivity can be adjust- ed before recording using the Movie settings > Microphone option in the shooting menu. If sound levels can be predicted, adjust sensitivity manually so
that peak volume does not exceed 12 db. Choose Auto if sound levels can not be predicted in advance.
