Step 1: Add a logic input and output pin for each microphone.
Use names for the logic pins that makes sense to you as you build your system. If you have many
microphones, you may add multiple digital logic inputs and outputs by adjusting the quantity before clicking
the add button.
Step 2: Create Mute Events on the button push
In this example it was desired to have the mute state toggled on all microphones when the PTT button is
pushed. To accomplish this, create two events – one to toggle the clink_mute parameter and one to use
the clink_mute parameter to mute "Mics".
The first event "Toggle Clink Mute" toggles the state of the clink_mute parameter on SoundStructure
device 1. If there are multiple SoundStructure devices in the system, then additional events are created to
map clink_mute on device 1 to clink_mute on device 2 and so on and finally map the clink_mute on
device N (N may vary from 2 to 8) back to the clink_mute on device 1 to ensure the mute state is synced
across multiple SoundStructure devices.
