Caution on video signals
● If search images or video signals with a high
level of jitter are input, images or sound may
be distorted temporarily. Thus, input stable
signals, e.g., those having gone through a
TBC.
● A digital VCR requires that video signals for
recording be delivered from a stable source.
Video signals from an analog VCR must be
run through a TBS or TBC.
● When a component output is executed for
composite-input video, discoloration may oc-
cur on the left side of the screen. It is not a
defect.
Ⅵ Synchronization signal
In order to enhance the level of edit precision,
input synchronization signals to all the devices
of the editing system during editing.
For BR-DV6000, input external synchronization
signals into the SYNC IN terminal. For external
synchronization signals, use video signals of 1V
(p-p) or lower (e.g., black burst signals).
Types of synchronization signal:
BR-DV6000 is operated based on one of the
following 3 types of synchronization signal.
• Synchronization signals produced by the syn-
chronization signal generator inside the VCR
(INT)
• Video signals from the video signal input ter-
minal (VIDEO)
• Synchronization signals from the SYNC IN
terminal (EXT)
Selection of synchronization signals:
Synchronization signals should be selected de-
pending on whether external synchronization
input (SYNC IN) or video input (VIDEO IN) ex-
ists or on the SYNC SELECT Menu settings.
Synchronization signals are selected as shown
in the following table.

Memo
● During DV signal recording, the status of
synchronization signals will be as shown be-
low regardless of the SYNC SELECT menu
settings.
● Regardless of the setting of SYNC SELECT,
when a tape recorded in PAL is played back,
synchronization signals are as shown below.
Caution on synchronization signals
● For external synchronization signals, output-
signal phase adjustments cannot be per-
formed. In addition, the sub carrier cannot be
locked.
● Plugging and unplugging of external synchro-
nization signals or video input signals during
playback causes distortion of images and
sound for about 5 seconds.
