Attenuation when the MIC/LINE level input goes to Talkback or
Program
It is possible to define an automatic attenuation on signals that feed the
headphone outputs when the corresponding inputs go from Program to Talkback
or vice versa. The attenuation will be carried out according to the following
critera:
Program, Cue or International Sound can be attenuated when the corresponding
input is connected to the Talkback channel. It is possible to define an
independent attenuation level for either of them.
The same thing can be done regarding Talkback Tx and Talkback Rx, that is,
either signal can be attenuated when the corresponding input goes to program.
V.2.2.2
Enable from TB Key
“Enable from Tb Key” is an additional option that only is available for Talback Tx
and Talkback Rx. When it is enabled, the corresponding signal will be sent to the
headphone outputs only when the corresponding input has been connected to
the Talkback channel, that is when its corresponding Tb key has been pressed.
