CONdITION SwITCHING
There are three modes which the system
can be in: Transmit (TX or On Air),
Rehearse, or Neither. These are controlled
from the ON AIR and REH buttons on the
broadcast facilities panel or from external
inputs set up on the GPI screen.
Each function can be set to be active, or
not, in any of the three states (except for
the “On Air” and “Reh” optos which can
only override the desk buttons or not).
The functions provided are to cater for
different requirements. Therefore some
combinations of settings will seem invalid.
