Synergy Series Operation Guide (v18) Background Transitions • 5–13
Please note:
• To clear the rate and cancel the procedure, press the
MLE RATE
button during the
entry process.
• To enter a different rate before pressing
ENTER
, simply continue to type until the
desired value is displayed in the register.
This completes the procedure to change the auto transition rates in the MLE Transition group.
Preset Black
The Preset Black function is a special two-stage transition that allows you to take the switcher to
black (or any other desired source) with the first transition, and then proceed to the next transition
previously indicated. The function is quite useful for dipping the switcher quickly to black, or
transitioning to a commercial. Note that the feature is
only available in the Program/Preset
Transition group.
In a default state, pressing PST BLACK causes the BLACK crosspoint to be selected on the PST
bus, replacing the currently selected PST source. The three buttons in the Next Transition Section
may change , depending on what is currently on air.
There are two stages to the transition:
• When you press PST BLACK , the switcher presets a dissolve to black. If a key (or both
keys) is on but their “next transition” buttons are not lit, the switcher automatically lights
the button for you.
The first transition dissolves the switcher to black, and dissolves off all keys. The
buttons in the Next Transition Section then change, presetting the switcher with the
original preview scene. This scene now is displayed on Preview .
• The second transition brings the switcher back up from black to the scene previously
shown on Preview — regardless of the combination of background and key sources
selected.
Use the following procedure to perform a Preset Black transition:
1. Ensure that the correct MLE is selected in the Preview Bus group.
2. Select a source on the PGM bus and a different source on PST . Re-entry crosspoints can
also be selected. Enable any combination of keys over PGM .
3. Press PST BLACK . The preview monitor will now show a black picture.
Important
Audio overrides will not be turned off for a PST Black transition. Any
audio overrides set on the PST Audio crosspoint bus will be taken to
air during the next transition. Refer to Chapter 21, “
Audio Mixers ” in
the Synergy Series Installation Guide for more information.
Important
Ensure that the White Flash option is set to
OFF
. Refer to the section
“ White Flash ” on page 5–14 for details on using the White Flash
option.
