onto the selected video bus (Background A, Background B,
Program, or Preset).
Any video or key input may be selected on any number of output
buses; however, only one output signal may selected at one time
on each output bus.
The SHIFT button located at the right end of each primary source
selection row is used to access the 16 or 24 shifted inputs. In
Normal mode, you select a shifted input by holding SHIFT down

bus. The
SHIFT button lamp then remains lit to show that the

another selection is made on that bus without holding down the SHIFT
button. So, even if the SHIFT button is already lit, in order to select
another shifted crosspoint on that bus, you must press and hold the
SHIFT button while selecting the new crosspoint.

sources that have been mapped to shifted crosspoints. This mode
is enabled in the Configuration/User Preferences Menu by
selecting LATCH.
When in Shift Lock mode (with the SHIFT button lamp off), to
select a shifted input, press and hold the SHIFT button (lamp
comes on) and press a crosspoint button on that bus. The SHIFT
button lamp then remains lit to show that the selection is a shifted
selection and that the bus is in the shifted state. (So far it looks
pretty much the same as Normal mode). The difference comes
when you select another crosspoint on the same bus. In Shift Lock
mode, whenever the SHIFT button is lit, if you make another
selection on that bus without pressing the SHIFT button, the
