5-1-1. Bus Button Sections
The video signals input to the switcher are assigned to the bus buttons on the control panel
for usage. The assigned signals are shared by the M/E1 bus section, M/E2 bus section, and
AUX/KEY bus section. In other words, selecting bus button 1 enables selection of the same
signal from any bus section. The names of the assigned signals are displayed over the M/E1
bus and M/E2 bus.
After the bus button is pressed to light it, a signal can be selected. The bus button indicates
the status by its lighting color. When it is lit red, the signal assigned to the bus is on-air. When
it is lit orange, it is set for the next output. For the M/E bus, the top is the PGM bus, and the
bottom is the PST bus.
The KEY bus is shared by KEY output and AUX output, and so when using as a KEY bus
(when it is lit after pressing the KEY1, KEY2, or KEY3 output select button), the insert (fill)
signal bus button assigned to that key is lit and displays the status.
