7. Operations
Understanding the T-Bar and Transition LEDs
4. Move the T-Bar to 50%. The T-Bar is now "live" again, and physical and virtual
positions are matched. You can move it up or down as required.
5. Move the T-Bar to 75%. The Transition LEDs match the position of the T-Bar .
6. Press AUTO TRAN to complete the transition. The Transition LEDs are all off,
but the physical T-Bar remains at 75%. In this situation, the T-Bar has no effect
on the video until you move it to either limit.

Use the following steps to demonstrate physical vs. virtual T-Bar position, in
conjunction with the recalling of memory registers:
1. In the M/E or the PGM bank, start with the T-Bar at the bottom limit.
2. Manually move the T-Bar to 25%. The Transition LEDs match the position of the
T-Bar .
3. For the bank in which you are working, save the bank in memory register 100.
This memory register stores the
T-Bar position by default. The register also
stores the direction in which the T-Bar was moving.
4. Move the T-Bar to 75%. The Transition LEDs match the position of the T-Bar .
5. Recall memory register 100 (in which the T-Bar position was saved at 25%). The
Transition LEDs are at 25% and the physical T-Bar position is at 75%. Physical
and virtual positions are not matched.
~
If you move the T-Bar to the top limit (the direction in which the transition
was originally going), it has no effect on the video — because the T-Bar ’s
physical position is already past its virtual position.
~
If you move the T-Bar back down towards the bottom limit, you will match
physical and virtual positions at 25% — at which point the T-Bar will
again be live.

Please note the following important points regarding the Transition LEDs .
•
( M/E bank only ) The Transition LEDs are not affected when the two “mix”
buttons in the Direct Key Control Group are used: MIX KEY 1 and MIX KEY 2 .
For example:
~
In the M/E bank, press AUTO TRAN to start an automatic transition, and
then press AUTO TRAN again to pause the transition. The Transition
LEDs are now paused between the limits.
~
Press MIX KEY 1 to mix on KEY 1 . The Transition LEDs remain at their
current location.
Refer to the “ Working with Keys ” section on page 287 for more details on the
buttons in the Direct Key Control Group .
Tip Always use the Transition LEDs to determine the T-Bar ’s
true virtual position.
