powered up all input channels will be off and assigned to PGM 1.
Cue Button
TheCUEswitch (notfound on theMIC channels)placesthe channel’s
signal on the console’s cue bus, where it may be heard in the external cue
speaker, as an interrupt to the console operator’s headphones, and as an
interrupt to the monitor speakers, if so programmed.
PresstheCUEbutton.Thechannel’sinputsignalwillbeincludedinthe
console’sCUEoutput at alevelthat is independent oftheFADER setting,
and the button will light. The fader does not need to be turned ON. To
remove a fader from cue, press the CUE BUTTON again; the light will go
off to indicate the channel is no longer assigned to cue.
Fader
Level is set by a long-throw fader. The fader is the sliding mechanism
that determines how strong is the presence of the input in some of the
various console outputs.
If the fader is all the way down (that is, pulled toward the console
operator), the signal will not be present in either of the two program main
busestowhichitisassigned.Asthefaderismovedup(thatis,pushedaway
from the console operator) the signal will appear more strongly in each of
the main buses to which it is assigned.
ON Button
The ON button turns the channel on and off by means of electronic
switching. The channel is on when the ON button is lit. The mic channels
canalso beprogrammed(asmentionedintheprevious chapter)toactivate
monitor mute and on air tally.
