31

<MIC/AUDIO1> and <MIC/AUDIO2> screens from the VTR
MENU page and select the settings for the items by

For details, refer to “Chapter 7 Menu description tables.”

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.

For the audio levels to be adjusted by one person only, it is
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.

performed manually.

respectively.
