Encoding the 8150 Output (NTSC)
STEP 12: Connect power to the A28. Verify that a composite version of
5-88
Engineering Setup
I/P KA and I/P KB: Use these inputs only if you are feeding
serial component digital key signals to the A28 that are
cotimed to the 8150 program or preview output. Note that
the A28 encodes only one input key signal at a time.
the 8150 output is present at all A28 video outputs. If Option
G is installed, you can adjust the levels and horizontal timing
of the analog outputs in a limited range, if needed, to match
you system's levels and horizontal timing.
NOTE: If you use the A28 to encode sources other than the
8150 set to 34 lines of delay, you must set DIP switch U15Q
segment 1 OFF. This setting, however, prevents using it to
encode the 8150 output with the correct timing, unless the
8150 output is set to one frame delay. See the A28 Technical
Manual for more information on this DIP switch and other
A28 timing controls.
