Setting Up Confidence Feed Control
This section explains how to remotely control the switching of confidence audio to
your Mix-Minus and Bus-Minus outputs. The way the system works is this -
• A “normally closed” relay closure from the master control switcher is used to
activate the confidence feed audio when the audio board is off air - not in the news.
During this time the Confidence Feed function is active and the audio source you
have selected in XPoint is heard at all Mix-Minus and Bus-Minus outputs.
• When master control takes the audio board live, the relay opens and normal
Mix-Minus / Bus–Minus audio is fed to the respective outputs.
To set this up you need to do the following:
1. Create a new DESTINATION signal in XPoint call it REM TRIG. Note that this
signal may be created anywhere there is an open signal space in the Destination
column. Make the signal be an INPUT and Logic I/O Only type. A typical
example of this signal definition is shown below.
