2 INPUT connectors
Use to input analog video and audio signals. To
connect a device equipped with S-video output, use the
S VIDEO connector on the unit. During normal
recording, sounds are recorded onto channels 1 and 2;
they cannot be recorded onto channels 3 and 4. During
audio dubbing, sounds are dubbed onto channels 3 and
4.
Notes
• In the audio dubbing mode, the AUDIO (CH-1/3)
jack functions as channel 3 input and the AUDIO
(CH-2/4) jack functions as channel 4 input.
• To input balanced audio signals via AUDIO jacks,
use a conversion cable as shown below. (The COLD
side is open.)
For details on conversion cables, refer to the instruction
manual of the devices you use.

3 AUDIO INPUT LEVEL (–10/–2/+4) selector
Selects one from among –10 dB, –2 dB, or +4 dB
according to the audio level of the signal input via the
AUDIO jacks in INPUT.
Notes
• If this selector setting is not appropriate, clipping
distortion or noise may occur.
• For more information on the setting of this selector,
see “When you set the AUDIO INPUT LEVEL
selector” on page 71 (GB).
4 NTSC/PAL select switch
Used to switch the color system of signals that will be
recorded on the unit when you use analog input.
Before inputting NTSC or PAL formatted analog video
signals, set this switch to the appropriate position
according to the color system of the signal input.
Notes
• If the color system of the input signals is different
from that of the switch setting, picture will be
blanked.
• While signals are input to the DV jack or during
playback, this switch setting is invalid. The unit
detects the color system of the signals automatically.
• When this switch is set to PAL, the unit works as a
PAL model. Therefore, the time code generated by
the unit during recording in the DVCAM format is
that of the non-drop frame mode. Even if an NTSC
formatted signal is input to the DV jack, the time
code generated by the unit is non-drop frame mode as
long as the switch is set to PAL, regardless of the TC
FORMAT setting on the TC/UB SET menu. If you
intend to set the unit to generate the time code in the
drop frame mode, set this switch to NTSC.
• The color system of the signals output from the unit
is the one recorded on the tape being played back.
The unit cannot convert the color system of signals of
one system into that of the other. (For example:
converting NTSC formatted signals into PAL
formatted signals is not possible) Therefore, to view
or record the signal output from the unit, you need a
device compatible with the color system of the
signals output from the unit.
• When the color system of playback signals is
different from the one last used on the unit, playback
picture and sound will be distorted and time code will
be discontinuous for a short time at the beginning of
the playback.
• If you play back a tape with both NTSC and PAL
color system recordings, the following limitations are
applied.
– At the point where the color system of the recorded
signals changes, the picture may be distorted or
audio noise may be output.
– The tape transport control buttons may be disabled
until the tape running is stabilized.
• Do not change this switch setting during recording.
• At the beginning or end of playback, if the color
system of signals recorded on the tape used is
different from this switch setting, pictures and sounds
output from the unit, and pictures on the LCD
monitor, etc., may be distorted.
5 DV jack (4-pin)
Used to input/output the digital signal that complies
with the i.LINK standard (Recommended cable: VMC-
IL4415 (A), VMC-IL4615 (A)). Use when a device
connected to the unit has a DV jack. If you connect the
unit and another device using DV jacks, you can
minimize deterioration of picture quality during
recording, dubbing, or capturing still pictures, all by
means of digital signal processing. For details, refer to
the instruction manual of the external device.

Rear Panel
1 OUTPUT connectors
Used to output analog video and audio signals. To
connect a device equipped with S-video input, use the
S VIDEO connector on the unit.
When the CHARACTER DISPLAY switch is set to
ON, data items, such as time data, menus, and
warnings, are superimposed on a monitor connected to
the S VIDEO and the VIDEO connectors.
For details on the superimposed data items, see
“Displaying Various Data” on page 23 (GB).
The audio output level of this unit is 2 Vrms (full bit).
When the AUDIO OUTPUT SELECT selector is set
to MIX, that drops to 50 % (–6 dB).
Notes
• Data items superimposed on a monitor connected to
these connectors are the same as those superimposed
on the LCD monitor.
You cannot make two monitors display different data
items individually.
• If you want to output video signals without text data,
carry out the following operations.
– Set the CHARACTER DISPLAY switch on the
front panel to OFF.
– Set TITLE DISP and LABEL DISP on the CM
SET menu to OFF.
– Depending on the displayed items, press the DATA
CODE or SEARCH SELECT button on the
Remote Commander to clear the text data on the
monitor screen.
For details on text data, see “Displaying Various Data”
on page 23 (GB).
For details on the CM SET menu, see “CM SET menu” on
page 58 (GB).
• In the EE mode (when the input signal is output as an
analog signal) or during recording, the subcarrier of
the color signal is not synchronized with the
horizontal sync signal. The color of the picture or the
horizontal sync signal may be distorted depending on
the type of monitor connected to the unit.
• Sync and burst signals of the EE pictures output via
these connectors are not synchronized.
• If DV input has been selected, color and luminance
may be distorted in the EE mode, depending on the
monitor.
• The unit only can accept standard video signals.
If you input the types of video signals shown below,
recorded picture, sound and the EE picture output via
these connectors may be distorted.
– Signals from some home game machines
– Blue background screen or gray background screen
from a consumer VCR
– Pictures played at a speed other than normal by a
VCR that does not have the TBC (Time Base
Corrector)
– Video signals in which the sync signals are
distorted
– Signals from a defective cassette (tape or recording
condition is bad) played by an analog VCR that
does not have TBC

Notes
• If video signals have been input to the DV jack and
you output these video signals to the S VIDEO or
VIDEO connectors, the sync and burst of the
corresponding EE pictures are not synchronized.
• i.LINK and the i.LINK logo “ ” are trademarks and
indicate that this product is in agreement with IEEE
1394-1995 specifications and their revisions.
• This jack can accept only DV signals.
• If the unit is connected to a device equipped with a 6-
pin DV jack, when you intend to disconnect or
reconnect the DV cable, turn off the device and pull
out the plug of its power cord from the AC outlet
beforehand. If you connect or disconnect the DV
cable while the device is connected to the AC outlet,
high-voltage current (8 to 40 V) is output from the
DV jack of the device to this unit, which may cause a
malfunction.
• When connecting a device that has a 6-pin DV jack to
this unit, first, connect the plug of the cable to the 6-
pin DV jack.
6 AC IN connector
Connects to an AC outlet using the supplied power
cord.
Even if the unit is in the standby mode, it consumes
power. To turn the unit off completely, pull the plug
out from the AC outlet.
7 CONTROL S IN jack (stereo minijack)
Connects to the Remote Control Unit (DSRM-20, not
supplied) for controlling this unit.
Note
When using the Remote Control Unit (DSRM-20, not
supplied), set COMMANDER on the OTHERS menu
to CONTROL S.
8 LANC jack
Use when controlling the tape transport operation of
the unit using a device that has a LANC
1) jack.
Notes
• The LANC jack on the unit has only LANC-S
functions. The unit has no LANC-M functions. A
device that is set to LANC-S mode cannot be
connected to this unit. Either this, the unit or the other
device may not operate properly.
• If the device that you connect to this unit has a
SHUTTLE A/B switching function and a LANC-M
function, set the device to the SHUTTLE B mode.
• The LANC connection transmits signals such as
control signals, time code, time counter data, and
status data.
• Jacks labeled CONTROL L have the same function
as LANC jacks.
• When using this unit as a player, set the LANC mode
on the recorder to M. A device that does not have an
M / S switching function cannot be used to control
this unit.
