Switch the input level to match the sensitivity of the
microphone used.
Switch the input level by changing the REAR MIC

MAINTENANCE menu (factory default setting is –60
dB).
For more details, see page 119.
Notes
• If the input level on this unit is not at an appropriate
setting for the microphone sensitivity, loud sounds may
be distorted, and the signal-to-noise ratio may be
affected.
• In order for the AUDIO IN CH-1 and CH-2 connectors
on the camcorder to be able to provide a phantom 48 V
power supply, female XLR connectors (3-pin) are fitted.
If the microphone cable has a female connector, use an
adaptor.
• When you detach a CAC-12 Microphone Holder once
you have attached to the camcorder, be careful not to
lose the two screws fixing the CAC-12 (in step 1). After
detaching the CAC-12, be sure to put the two screws
back into their original places.
