ROUTING page. In such a case, a dashed vertical line is displayed for the
corresponding input unit (channels 01, P, and R in the picture above).
There are cases where the signals must be routed "to the background", i.e.,
it is possible for input channels to be active, but without operating ele-
ments on the console surface, e.g. if the user deliberately decides that some
input channels must be in the background.
All input channels currently routed to the background can be displayed in
the CHANNEL ON/OFF page; this page is selected by touching CHN
ON/OFF in the HOME page.
When routing an input unit signal to the background, the audio path re-
mains open, and the audio passes through the console with the fader level
set at the moment of routing the signal to the background. This can be
used, for example, for input channels being controlled in the background
by a broadcast automation system (e.g. DigiMedia) using the serial port.
External MUTE control for the input channel is still available.
Notes: This could be dangerous for a new user taking over the console, or for un-
experienced users. Therefore being in the HOME page, the HOME field
toggles to CHN ON/OFF. When touching this field, the CHANNEL
ON/OFF page is opened (see below), displaying all input channels not as-
signed to fader strips (i.e., being in the background); the highlighted ones
are open for audio signals ("ON"). Now, the user can switch any input
channel ON or OFF on this page directly by touching the corresponding
field on the screen.
When the PFL function is active at the moment of routing an input channel
to the background, it is automatically switched off.
When powering the console off and on again, the input channels in the
background are always set to OFF, to prevent audio from being played out
unintentionally.
When a new channel routing is loaded or when a user logs in, the input
unit-to-fader strip assignment is modified. In this moment, the audio level
of an input signal may not correspond to the physical position of the new
fader. As the OnAir 1000 does not feature motorized faders, in such a case
the Auto Takeover LEDs indicate in which direction the fader knob has to
be moved to "catch" the audio level and to get the signal under control
again.
