7. Operations
Understanding the T-Bar and Transition LEDs
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.
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 333 for more details on the
buttons in the
Direct Key Control Group.
(PGM bank only) The Transition LEDs are not affected when the FTB (Fade to
Black) button is used. For example:
~ In the PGM 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 FTB. The Transition LEDs remain at their current location.
Tip
Always use the Transition LEDs to determine the T-Bar’s
true virtual position.
