6. Operation
Working with Transition Type and Rate
• ‘Active Preview Keyers’
Some operators like the “PresStation” method of arming DVEs, DSKs, and voice-overs on the
preset bus. Other operators like the traditional method (which is used for MCEs and MCPMs).
When this option
— coupled with ‘Enable Traditional PST Tally’ of the MCS Panel Configura-
tion Editor — is chosen, the panel will operate using the traditional method. Otherwise, the
panel will use the PresStation method.
• ‘DSK n Preview Keyer Position’
This basically turns the Imagestore 750’s individual DSKs on or off.
If your panel has DSK buttons, and they are disabled in the Imagestore 750’s configuration, the
buttons will be disabled on your panel. They might be enabled for another Imagestore 750.
• ‘Aux Bus Follow’
This option — although not strictly a transition option — has 3 choices: ‘none’, ‘PGM’, or ‘PST:
When the option is ‘PGM’, the aux bus “follows” the program bus. That means that whatever
source you select on the program bus is also selected on the aux bus.
When the option is ‘PST’, the aux bus “follows” the preset bus.
When the option is ‘none’, the aux bus does not “follow” either bus and operates normally.
Note that when the option is ‘PGM’ or ‘PST’, you can still use the aux buttons, normally, to
switch sources to your aux output.
Working with Transition Type and Rate
It is the Imagestore 750 that stores the transition type and rate. It supports 8 transition types: cut,
V-fade, cut-fade, cross-fade (or X-fade), fade-cut, U-fade, V-fade preset 1, and V-fade preset 2. (A
U-fade is like a V-fade with a dwell period in the middle. The dwell period is pre-configured. The
characteristics of the V-fade preset 1 and preset 2 are also pre-configured.)
Rates are ‘Slow’, ‘Medium’, and ‘Fast’. Your panel might have an ‘Automation Rate’ button which
selects whatever rate is in effect in the automation system in your facility.
The Imagestore 750’s A/B mixer has its slow, medium, and fast rates. You can change these rates in
the ‘A/B Mixer’ menu.
Each DSK has its own rates (slow, medium, and fast) and each voice-over has its rates. You can
change a DSK’s three rates in its menu. Larger values are slower rates. The range of values is 1 to
999. You cannot change the rates of a voice-over from the panel.
By convention, transition type and rate buttons are assigned to the ‘Transition Control’ button
group at the front of the panel. However, any of these functions can assigned to any configurable
button.
To select a transition type, simply press one of the transition type buttons. The button will go high-
tally and other transition type buttons go low-tally. To select a rate, press one of the transition rate
buttons.
A “cut” transition does not involve a rate and any rate buttons on your panel become disabled.
