Adjusting the audio recording levels
When carrying out audio recording at a
reference level
Leave the REC controls pressed in. The audio signals
will be recorded at a preset reference level (a reference
0 dB indication for an input of +4 dBm).
Manually adjusting the recording levels
For each channel, pull out the REC control in the
upper control panel, and adjust so that the audio level
indication is 0 dB for an average volume. Carry out
the adjustment in E-E mode.
For details of selecting the E-E mode, see the description of
the REC button in the tape transport control section (page
2-13) and the PB.EE button in the monitor/menu/display
setting section (page 2-8).
To change the display range of the audio
level indications
Press the DISPLAY FULL/FINE switch (see page 2-
4).
To monitor the simultaneous playback of
the recorded video and audio signals
Press the CONFI button to light the CONFI indicator.
It is now possible to simultaneously monitor the video
and audio signals being recorded.
In the editing mode, for the playback interval around
an edit operation, CONFI playback is also possible.
While CONFI playback is actually being carried out,
the ON indicator lights.
To monitor the video and audio already
recorded on a tape
Press the PREREAD button, turning it on.
It is possible to monitor the video and audio already
recorded on the tape, before the new recording.

Chapter 4 Recording and Playback
To use the emphasis function
To add emphasis to the analog input audio signal or
analog playback audio signal, set the extended menu
item 817 to ON.
When the signal to which emphasis has been applied is
played back, it is automatically subjected to
deemphasis processing.
Using the emphasis-deemphasis processing enables the
dynamic range to be improved by reducing high-
frequency noise.
4-1-2 Recording Time Code and
User Bit Values
There are three ways of recording time code, as
follows:
• Setting an initial value, then recording the output of

• Recording the output of the internal time code
generator synchronized to an external time code
generator
• Recording an external time code without
modification
To set an initial value then record the time
code
If necessary, change the settings in the time code
setting section (see page 2-5).
