Talkback-related Minimixer Parameters
Select the Minimixer you wish to edit in the "Minimix" branch of the 'Treedefintion' and open the
Sys TB
tab to
define its talkback parameters:
Each source can be summed with both left and right channels of the minimixer using a single control signal (
Sys
TB 1
and
Sys TB 2
). Or, each source can be summed independently with the left or right channels (e.g.
Sys TB
1L
and
Sys TB 1 R
). This second option allows talkback to be inserted on only one side of the minimixer.
Level for each talkback source can be assigned to a level control - see
Sys TB 1/2 Level
-
or set to a fixed value -
see
Sys TB Level (init)
.
Sys TB 1 Select
Sys TB 2 Select
Assigns
Sys TB 1
and
Sys TB 2
to one of the
eight pre-defined talkback signals (in
System -> Definition -> Audio = Internal
”).
Note that these fields are not supported by crystal, as only two talkback signals are
supported.
Sys TB 1
Sys TB 2
Assigns input control signals to sum each talkback source with both the left and right
channels of the Minimixer.
Sys TB 1 L/R
Sys TB 2 L/R
Assigns input control signals to sum each talkback source with either the left or the right
channel of the Minimixer.
Note that the
Sys TB 1
and
Sys TB 1L
control signals are OR’d – this means that audio
source 1 will be inserted to the left channel if either control input is true.
Sys TB 1/2 Level
Assigns level controls to adjust the level of the two talkback sources. If left blank, then the
SysTB Level
(init)
will be applied.
Sys TB Level (init)
This is the level applied if the
Sys TB 1 Level
or
Sys TB 2 Level
are not assigned. The
level is set in dB.
