6. MLE (Multi-Level Effects)
An MLE can be thought of as an individual video layer that can be combined with other
images, keys and MLEs to form the composite switcher output. Each MLE is composed
of three rows of crosspoints (one per video or key input source).
• At the top, the Key Bus (labeled
KEY
) is used to select key sources that can be
keyed (electronically cut) into the MLE’s background image. The Key Bus is
shared between the MLE’s two keyers (Key 1 and 2). Two LEDs at the top right
edge of the bus indicate which keyer currently has control of the bus.
• The Background Bus (labeled
BKGD
) selects the source that comprises the MLE’s
background image — that is, the image that is visually behind all other images (or
farthest upstream, electronically).
• The Preset Bus (labeled
PST
) selects the source on the MLE that you are
transitioning to — using a cut, dissolve, wipe or DVE transition.
At the right-hand side of the bus are several special buttons and LEDs:
• Re-entry buttons allow you to add (or combine) the contents of an entire upstream
or downstream MLE to the MLE’s output video content. The number of re-entry
buttons depends on the model.
• For tally information,
ON AIR
LEDs (one per bus) light red to indicate when a
crosspoint selected on that bus is used as part of the output video.
• For bus status,
N/S
LEDs (one per bus) light yellow to indicate when a
non-synchronous source has been selected on the bus.
The layout of an MLE is identical on all three switchers, except for the differing
numbers of crosspoints and re-entry buttons.
7. Custom Control Group
The Custom Control Group provides an array of buttons that can be programmed to
perform specific functions such as peripheral device control, switcher memory recalls or
switcher macros. A macro is essentially a series of button presses that can be played
back in succession, at the touch of a single
Custom Control button.
On the Synergy control panels that were manufactured prior to 2003, the Custom
Control group is identical on the Synergy 3 and Synergy 4 panels, with an array of 32
buttons available for programming. The Synergy 2 panel has an array of 24 buttons.
For the Synergy 2, 3, and 4, 2003 Edition panels, there are 17, 30, and 35 buttons,
respectively, situated above the
Program/Preset Bus .
8. Aux (Auxiliary) Bus Group
The Aux Bus Group is comprised of two distinct areas:
• The sources on the Aux Bus Crosspoint Row can be mapped in one of two ways.
One method is to map the crosspoints identical (in both source and quantity) to
those on the specific switcher’s
Program/Preset and MLE buses. You can also
map BNCs to the Aux Bus Crosspoint Row without changing the crosspoints on
the MLE buses.
All sources are present, except for re-entry crosspoints. Because each Synergy
switcher includes 12 Aux Buses as standard, this row is
shared between all 12
outputs. In terms of functionality, the bus is used to select the sources that are routed
to specific
external destinations, such as DVE inputs, still stores, tape machines,
and technical areas.
