For destination devices that are sensitive to timing (such as a D-A converter), the Timed
Aux Bus outputs are ideal.
Note that the Timed Aux Bus option is easily installed in the field.
Dedicated and Assignable Remote Aux Panels
A Remote Aux Panel is a self-contained switching unit that has its own power supply. It mounts in a
19-inch rack and fills one RU (Rack Unit). There are two types of remote Aux panels available for
each Synergy switcher:
• A Dedicated Remote Aux Panel controls one Aux Bus output. The Dedicated Panel for
the Synergy 4 is shown below:

• An Assignable Remote Aux Panel controls all 12 Aux Bus outputs. The Assignable
Panel for the Synergy 4 is shown below:

Thus, there are six Aux panels available in the product line. All panels include dedicated buttons for
DVE Send, Program, and Clean Feed — plus a bright “on air” LED. Assignable panels (only) include
buttons to access the 12 Aux Bus outputs.
The primary difference between the panels is in the number of source and MLE buttons:
• Synergy 2 — each panel includes 17 source buttons plus SHIFT , and a button for
MLE 1 .
• Synergy 3 — each panel includes 30 source buttons plus SHIFT , and buttons for MLE 1
and MLE 2 .
• Synergy 4 — each panel includes 35 source buttons plus SHIFT , and buttons for
MLE 1 , MLE 2 , and MLE 3 .
The remote panel itself is connected to the rear of the switcher’s control panel via a single
six-conductor telco control cable. Cable runs up to 1000 feet (305 meters) are possible. Typical
applications include routing signals to one or more DVE channels, and switching a monitor between
various signals (including MLE outputs) — outputs that are
not the main program output.
An unlimited number of Aux panels can be connected to each of the control panel’s two Aux
connectors, but for a
practical limit (and to minimize delay), a maximum limit of 16 Aux panels
should be observed. This limit thus allows eight panels to be daisy-chained on each of the two
connectors. Please note:
• Both the Dedicated and Assignable Aux panel options include a 33-foot (10 meter)
cable. Custom cable lengths are available.
• The maximum cable length between panels (as limited by RS-422 specifications) is
1000 feet (305 meters).
• The communications signal is re-buffered at each Aux panel.
