Key1-4 Cut/Key1-4 Fill
These inputs are for the four external key sources. A key cut/ key fill
input pair is available for each.
Note There are only four physical connections on the rear panel for key cut/key fill
pairs although these four connections may be associated with any four of the
eight available keyers.
Audio Over 1-4
These inputs are used to route sources for audio overs.
Note There are only two physical connections on the rear panel for audio overs
although these two connections may be associated with any two of the four
available audio overs.
Although there are only two inputs on the rear panel for AES audio
overs, all four audio mixers may be used if a Sonata AES-to-MADI con-
verter is used to convert AES sources to MADI.
AssignSRC 1-16
In some master control implementations, it is desirable to display the
sources assigned to the 16 Maestro background buttons on the monitor
wall. Router outputs may be assigned to AssignSRC1 - AssignSRC16 which
will display the source assigned to the corresponding background button
on the monitor display connected to the designated router output.
Other Columns
The remaining column headings of this table will show the Level names
from the Step 2 “Level” table (
page 117 ). For each field, select the name of
the router output that will be associated with the Maestro input for the row.
For Jupiter systems, these names correspond to the output names in the CP
Output Set previously assigned to the Maestro system.
Note If a source for key cut, key fill or audio overs is directly connected to a
Maestro input (see Source Types
on page 152 ), there should be no Intercon-
nection definition for that input.
General Purpose Input/Output (GPIO) Definition
GPIO connectors allow external devices to trigger Maestro events (Keyers
on/off air, audio overs on/off air, etc.) or for Maestro to trigger external
events such as source tally and bus tally.
GPIO actions are triggered by contact closures on the GPIO connector on
the Maestro rear panel. For pinouts of the 44-pin GPIO connector, refer to
Table 1 . For a representative schematic of the GPIO port, refer to Figure 118 .
