4-4-2 Adjusting the audio signal recording
levels
The procedure for manually adjusting the levels at which the
signals are to be recorded on audio tracks CH1 and CH2 is
set forth below.
1
Set the MONITOR SELECT switch to the CH1/2 position
so that the audio level meter display in the display
window indicates CH1 and CH2, and check that 1 and 2
are actually indicated as the display in the display
window. Before proceeding any further, on the menu,
set whether to activate the F.AUDIO LEVEL controls
which are used for attenuation. (At the factory, the mode
in which these controls are inactive is established.)
2
Set the AUDIO SELECT CH1 and CH2 buttons to MAN
(manual).
3
While monitoring the audio level meter in the display
window or the audio level meter display inside the
viewfinder, adjust the AUDIO LEVEL CH1 and CH2
controls. If the uppermost bar (0 dB) is exceeded, the
"OVER" display lights up to indicate that the input
volume is too high. The level must be adjusted so that 0
dB will not be indicated even under maximum volume
conditions.

recommended that the F.AUDIO LEVEL controls be used.
Select in advance the audio channels whose levels are to be
adjusted, and while monitoring the level meter on the
viewfinder screen, adjust the F.AUDIO LEVEL controls in
such a way that the input will not be too high.
