Push To Talk Microphone Events
When adding Push to talk microphones to a project, there are several logic
input mode options for what should happen when the button is pressed.
There are also several logic output modes available for what the status LED
should indicate.
The automatic options for the Logic Input Mode include:
• Toggle microphone mute – toggle the mute on this particular microphone
when the button is pressed
• Toggle all microphone mute – toggle the mute on all microphones when
the button is pressed
• Push to mute – push and hold this button to mute the microphone (e.g., a
cough button)
• Push to talk – push and hold this button to unmute the microphone
The automatic options for the Logic Output Mode include:
• Active on mute – illuminate the LED when the microphone is muted
• Activate on unmute – illuminate the LED when the microphone is
unmuted
• Activate on gate – illuminate the LED when the microphone automixer
gates on
These options are provided to make it easy to automatically create events
based on the desired behavior. These events may be further customized by
double clicking on any event to open the Edit Event user control.
Depending on the selected logic input and output behavior, different events
will be created. The following table summarizes the events created for the dif-
ferent logic input mode options.
