Creating an "On-Air" Tally

This example demonstrates how to create on an "On-Air" tally when any of a series of
mic channels is tracked. For the purposes of illustration, it is assumed that channels 1
thru 8 are mic sources and that an On-Air light is switched on and off via the GP132's
GPI relay output 1.
First we must create an Event to close the GPI relay (turn the "On-Air" light on) when a
mic channel is tracked (see Figure 11-4):
1. Touch the
2. Event List area, touch <Press to Add Event> and type something descrip-
In the
tive in the keyboard popup.
3. In the Inputs area, touch the <Press to Add Input> and select OnAir from the
Add Input Event popup.
4.
Enter the following values:
Start Channel
End Channel
Activation Level
Activation State
5. Outputs area, touch the <Press to Add Output> field and select GPO from
In the
the Add Output Event Popup.
6. Enter the following values:
Output Number
Active State
Pulse Length
Machine
7.
Now, while any of channel 1 thru 8 are tracked (any fader above -72 and ON), GPI
output 1 is latched closed.
8. In addition, an output action can be added to simultaneously mute a floor monitor
attached to one of the console's Monitor outputs. Create another Output and se-
lect Control Room. In the properties area, select values "Monitor A" and "Off."
