AuxKeys
TM
, System Wide S4MDX-055
This revolutionary and highly recommended option turns Aux Buses into A/B mixers or
mixer/keyers. Key and mix sources are fed from adjacent Aux Buses that have access to
every signal in the switcher. Mix or key operations can be previewed and clean feed is
available also – this is very much like a simple MLE. The use of a single AuxKey can
free up an entire MLE in many applications. Of particular interest in this application
are Global-Store outputs that, with MediaCache enabled, can provide animated logo
capability.
AuxKeys can be used two ways:
• Mixer (mix between two video buses)
• Mixer/Keyer (mix and key – required 4 buses)
Switcher outputs are assigned to AuxKeys in groups of four. A maximum of 11 AuxKeys
may be enabled on a Synergy 4 MD-X. This would require the installation of three output
cards. If MultiDSK is purchased and activated, the maximum possible number of
AuxKeys is reduced to 10. The diagrams below show sample configurations of AuxKeys,
both with and without option S4MDX-056: MultiDSK installed:

AuxKey Configuration without MultiDSK Option Installed
In the above example:
• The first group of four is configured as a simple mixer freeing up outputs K03
and K04 to be used as fully configurable outputs.
• The second and third groups of four are not configured as AuxKeys and are fully
configurable.
• The last group of four is configured as a mixer/keyer. Output K13 is the first
AuxKey “program” output, output K14 provides an identical second AuxKey
program output, output K15 is the AuxKey preview output, and output K16 is a
Clean feed output taken after the mix stage but before the keyer.
