VIDEO INPUT connectors
Inputs 1 — 4: BNC
connectors
with
bridged
connection.
When
not bridge-connected,
set the 75 2
termination switch to "ON".
GENLOCK/5:
For
genlock
operation,
input
composite
video (VBS) or black
burst (BB) signal to
this connector.
When
there
is no signal input to this con-
nector,
the synchronizing
mode
is set to
internal mode (INT MODE)
using the built-
in SSG.
Q@VIDEO INPUT 5 SELECT switch
When the input to GENLOCK/5
connector @ is used for
genlock and when all the input connectors
1 to 4 have
already been used, the GENLOCK/5
input can be used as
the fifth video input signal by setting this switch to "[5]'"'.
Consequently, a color background cannot be used.
However, when the input to the GENLOCK/5 connector is
off, the fifth input reverts to the background color even if
this switch is set to "(5)".
@KEYING
SIGNAL INPUT connectors
DSK:
Video signal input for downstream keying.
CHROMA
KEY:
Video signa! inputs for chroma
keying.
(R/G/B signals without sync)
(EXT. KEY):
Video signal input for external keying.
Note:
@
Among the above keying functions, chroma keying and
external keying cannot be performed at the same time.

Program video output connectors.
PREVIEW:
Preview video output connector.
DSK PREVIEW:
DSK preview output connector. By moni-
toring this output, the settings (slice and
color levels) of the downstream keyer can
be checked
without
inserting it in the
program line.
BB-1
a
ae
Outputs of black burst™
signal.
BB-3:
When the BB/VD
switch is set to "BB",
the black burst signal is output from VD/
BB output connector @.
* Black burst signal: A composite signal consisting of sync
and burst signals.
@SYNC
PULSE OUTPUT
connectors
75 Q output connectors for HD, VD. SYNC and BL signals.
Used for the genlock of a B & W camera for DSK or EXT
keying.
SYNC:
— Sync signal output.
HD/BL:
HD or BL signal output selectable by the switch.
VD/BB:
The signal (VD or BB) selected by the BB-3 select
switch of @is output.
@AC INPUT
Connect the AC power cable provided.
@DC
INPUT
XLR-type
4-pin
connector
for operating the unit with a
12 V DC power supply.
Notes:
@ The
DC
power
used should
have a rated capacity of
more than 1.5 A.
@OTALLY connectors
The tally system uses the power supply method
(with 5 V
DC output) and the power is supplied through these termi-
nals.
