5. OPERATIONS
5.1.
System Adjustment
After
making connections,
it is necessary
to perform this
"system adjustment" as the signal levels and phases are not
matched between the individual units making up the system.
Only a simplified adjustment procedure is described here. The
adjustment is more precise when a vectorscope and waveform
monitor are connected to the output.
(1) Turn on all units in the system.
When power is switched on, the KM-1200
is automatically
set for A bus line ''1'', B bus line ''1'', PREVIEW
bus line
"1 MODE ""MIX'", and PROGRAM
'1.
Set the
BARS
switches
of the connected
color video
cameras to "ON" to generate color bar signals.
[3] Set the controls on the KM-1200 as follows:
@ Set the MIX/WIPE lever to ''A''.
@
Set the DSK ON/OFF
button to "OFF"
and turn the
OSK
LEVELand DSK SLICE controls counterclockwise.
@ Set the CHROMA
KEY
ON/OFF
button
to "OFF"
[4] Switch the PREVIEW
bus-line buttons and monitor the
preview monitor to check that the color bars signals from
the cameras are input.
@ Check that the 75 Q termination switches of the input
connectors
are set to "ON".
(Terminate
also unused
input connectors.)
[5] Adjust the horizontal phase and subcarrier phase.
1) Press the INPUT A and PREVEW buttons "1".
2) Press the AUTO
TAKE button.
3) Press the PREVIEW buttons "1" and ''DSK" alternately.
At this time, adjust the
H PHASE control of the camera
connected to "1 so that the picture is not shifted to
the left or right on the preview monitor screen.
Similarly, adjust the SC PHASE controls on the cameras
so that the hues of color bars from different cameras are
the same.
[6] Perform these adjustments for all the cameras connected.
Shoot the same object (gray scale, etc.) with all cameras,
and fine-adjust the black level (pedestal level), white level
(video level) and chroma level, etc.
Note:
@
For the operation of the color video cameras and remote
control units, refer to the instructions provided with them.
@
For
EXT.
genlock
operation,
subcarrier
phase
adjust-
ment
is necessary.
