provide connection to microphones, digital recorders, external audio
mixers, sound boards, and other equipment, by means of two balanced
XLR inputs.

audio devices, set to LINE for Line. When using microphones
operating on phantom power, set to PH for phantom power.
DO NOT select phantom level when recording with microphones
that do not operate on phantom power, wireless receivers,
mixing boards or any unbalanced devices, because it may
cause damage to both the adapter and audio device.

14. Turn the POWER switch to ON.
15. Plug an earphone into the headphone terminal on the camera
to monitor the audio. Make sure that both channels can be
