Adjustments and Settings for Recording
This unit is capable of recording 4 independent audio channels in all recording formats except for native recording with VFR.
When the AUDIO SELECT CH1/CH2 switch is positioned at [AUTO], the recording levels for audio channels 1 and 2 are 
automatically adjusted. To manually adjust the recording levels, position the switch at [MAN]. Note that the recording levels for 
audio channels 3 and 4 are selected through a menu option.

						

							62Adjustments and Settings for Recording: Selecting Audio Input Signals and Adjusting Recording Levels To adjust the recording levels for audio channels 1 and 2, 
follow the steps below.
1Position the MONITOR SELECT CH1/2 / CH3/4-
selector switch at [CH1/2] so that the audio level meter 
on the display window will provide CH1 and CH2 
indications. Ensure that the channel indications 
displayed in the window are “1” and “2”.
Whether to enable or disable the FRONT AUDIO 
LEVEL control must be preset through menu options 
FRONT VR CH1 and FRONT VR CH2. Note that this 
control is factory-disabled.
The menu options are found in the  
screen on the MAIN OPERATION page.
2Position the AUDIO SELECT CH1/CH2 switch at [MAN].
3While checking the audio channel level meter in the 
display window or the audio level meter in the 
viewfinder, adjust the AUDIO LEVEL CH1/CH2 control.
Note that if the level exceeds the top bar (0 dB), the 
word “OVER” illuminates to show that the input level is 
excessive. The adjustment made in such a way that the 
maximum level will not reach the 0 dB bar.

When operating the unit without a sound recordist, it is 
recommended that the FRONT AUDIO LEVEL control 
should be used to adjust the audio level.
Preset the channel to be adjusted, and use the FRONT 
AUDIO LEVEL control to adjust the audio level while 
checking the audio level meter in the viewfinder to ensure 
that the level does not become excessive.
This function enables the recording level to be adjusted 
using the FRONT AUDIO LEVEL control.
To select this function, perform menu operations to open the 
 screen from the MAIN OPERATION page, 
and set whether to enable or disable the FRONT AUDIO 
LEVEL controls for the system selected as the input signals 
using the FRONT VR CH1 and FRONT VR CH2 items.
The following table shows the effects on the recording level 
for audio channels 3 and 4 that depend on the settings and 
input levels specified through the menu options AUTO 
LEVEL CH3 and AUTO LEVEL CH4. Note that the recording 
level cannot be adjusted manually.
These options are found in the  screen on 
the MAIN OPERATION page.

							63Adjustments and Settings for Recording: Setting Time Data
Adjustments and Settings for Recording
The unit supports time codes, user bits, date, and time (real time) data, which are recorded as data for the sub-code area, 
VIDEO AUX area, and clip metadata files. It also includes a CTL counter and camera ID.
The TCG switch can be used to switch between Rec run and 
Free run.
Free run: The time code always advances even when 
the power is turned off. It can be handled as 
time. It can be slaved to the time code input 
through the TC IN connector.
Rec run: The time code is recorded as sequential 
values regenerated as the time code for a clip 
recorded on a P2 card.

						

							64Adjustments and Settings for Recording: Setting Time Data The following shows recording time codes and user bits for different input signal formats, and SYSTEM MODE and CAMERA 
MODE settings.
*1 If the menu option FRAME RATE UB on the  screen is set to “MENU”, then recording is performed as per the UB MODE or 
VITC UB MODE. Note that, with this setting, information required by editors (PC editing software) is not recorded.
*2 For Free run, the time code is slaved to the time code input through the TC IN connector.
*3 For Free run, the time code is slaved to the time code input through the TC IN connector if it is a non-drop frame.
*4 When the menu option UB MODE is set to “EXT”, then the bits are slaved to the user bits input through the TC IN connector.
*5 Regardless of the menu settings, frame rate information is always recorded. During playback, the information is output after being 
converted into pull-down frame rate information.
*6 When the menu option UB MODE is set to “FRM RATE”, the pull-down frame rate information read out from the UB in the VAUX area is 
output during playback.
*7 For details on this item, refer to [Recording formats and output connector signal formats] (page 50).

The unit’s internal time code generator can be locked to an 
external generator. In addition, the external time code 
generator can be locked to the unit’s internal generator.
As the figure shows, connect both the reference video signal 
and reference time code.
Example 1:When locking onto an external signal
a.Reference time code
b.Reference video signal

						

							70Adjustments and Settings for Recording: Setting Time Data As a result of processing to convert the video captured by 
the imaging devices from a progressive signal to an interlace 
signal, video signal delays will occur in the camera.
Since time is required for making the 2:3 pull-down from the 
24P frame, there is a video signal delay in the camera.
When recording from a device that can record images 
without a delay and the unit is connected in parallel, it is 
necessary to synchronize the time code. To set this timing, 
open the  screen from the MAIN OPERATION 
page and set it in the TC VIDEO SYNCHRO item.
Set by referring to the connection example.
Example 3:When the unit and an external device are 
locked to the external time code generator, 
which is connected externally, and when 
simultaneous recording is made by using the 
TC OUT output signals.
