Step 3: Create LED event based on the Mute state
The final event required maps the mute state of the microphone to the LED state. In this example, it is
desired to light the LED (logic output = 1) when the microphone is unmuted (mute = 0). To accomplish this,
use an invert in the map action, as shown in the following figure.
The full set of events is shown on the Events page and displays as the figure shown below.
For each additional microphone that it is desired to add PTT logic, create additional Toggle Clink Mute and
Table Mic Status LED events for each microphone. Only one "Clink_mute to Mics Mute" event is required.
Remember, if you have microphones across multiple SoundStructure devices you will require events that
will map the clink_mute of device 1 to the clink_mute of device 2, and so on to ensure the clink_mute
parameter on all devices is synchronized together.
