Basics of Signal Selection

Each of the switcher banks have 24 cross-point buttons in
their cross-point control blocks.
These buttons are identified by numbers common to all of
the banks and blocks, and a signal is assigned to each
number.
The basis of signal selection is to select, in a cross-point
button row, the cross-point button to which the desired
signal is assigned.
M/E reentry signal selection
A video signal created on the M/E bank can be imported as
an input signal on the PGM/PST bank. These signals are
referred to as "M/E reentry input" signals.
To select an M/E reentry input signal using the cross-point
buttons, the signal must be assigned beforehand in the
Setup menu (1 p. 223).
For example, if the program output from the M/E-1 block
(M/E1 OUT) is assigned to an arbitrary cross-point button,
the signal can be used as input material at any time.

Bus Selection

Each row of the 24 cross-point buttons is shared by
multiple buses.

Signal Assignment and Selection

Assigning signals to buttons
Each of the 24 cross-point buttons has a corresponding
button number, to which you assign a signal.
In addition to the signals input to the connectors at the rear
of the switcher processor, you can also select signals
generated within the switcher.
Each button has assigned to it a video signal and a key
signal, forming a pair. You can set these video and key
combinations in the Setup menu.
