Chapter 4 Recording and Playback

To adjust the audio recording levels

When carrying out audio recording at a reference

level

Leave the REC knobs pressed in. The audio signals will be

recorded at a preset reference level (a reference –20 dB

indication for an input of +4 dBm).

To manually adjust the recording levels

For each channel, press to protrude the REC knobs, and

adjust so that the audio level indication is close to 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 knobs (page 19) and the F6 (PB/EE) setting in

function menu page P01: HOME (page 64).

To change the display range of the audio

level indications

In function menu page P08: AUD INP, select F4

(MT.SCALE) (see page 68).

To monitor the simultaneous playback of

the recorded video and audio signals

during recording

In function menu page P01: HOME, select F7 (CONFI)

and set it to “ENABLE” (see page 64). It is now possible

to simultaneously monitor the video and audio signals

being recorded.

To use the emphasis function

To add emphasis to the analog input audio signal or analog

playback audio signal, select F1 (EMPHASIS) in function

menu page P08: AUD INP and set it to “ON” (see

page 68).

When the signal to which emphasis has been applied is

played back, it is automatically subjected to deemphasis

processing.

Using the emphasis-deemphasis processing improves the

dynamic range by reducing high-frequency noise.

4-1-2 Recording Timecode and User

Bit Values

There are two ways of recording timecode, as follows:

• Setting an initial value, then recording the output of the

internal timecode generator

• Recording the output of the internal timecode generator

synchronized with an external timecode generator

To set an initial value then record the

timecode

If necessary, change the settings in function menu page

P02: TC (see page 65).

To set an initial timecode value

Use the following procedure.

In function menu page P02: TC, set F1 (TCG SRC) to

“INTERNAL” and F2 (TCG MODE) to “PRESET”.

In function menu page P01: HOME, set F8

(COUNTER) to “TC”.

Select F10 (TCG SET).

The function menu display changes as follows.

The first digit of the timecode value (8 digits: hours,

minutes, seconds, and frames) flashes.

To set all digits to zero

Select F5 (CLR CNT).

Select F1 (PREV) or F2 (NEXT), and select the digit

to be changed.

Selecting F2 (NEXT) moves the flashing digit position

to the right, and selecting F1 (PREV) moves the

flashing digit position to the left.

Turn the MULTI CONTROL knob or select F3 (–) or

F4 (+) to change the value in the flashing digit

position.
