They might not be very pretty to look at but they work great. These have Arduino microprocessors in them that communicate via the WiFi network to our Yamaha TF3 inside the OB Truck. We currently have them setup for Channels 1 & 2 on the TF3 board. There are three momentary buttons RED, YELLOW & GREEN. 

The RED “ON AIR” button basically sends a MUTE/UN-MUTE command to the TF over the network so our commentators can take themselves ON-AIR or OFF-AIR. 

If they hold the YELLOW “MUTE” button they will be temporarily muted as long as they old the button down. This acts more like a cough-mute button.

The GREEN “TB” (Talkback) button does several things, it first MUTES their Mic then opens another channel/aux on the TF where we have a talkback channel so they can speak directly to everyone in the OB Truck. This has been very useful during productions! It gives us two-way communication without the need for the commentators to have a separate intercom headset. 

Currently how the truck talks back to the Commentators is via a Mic we have setup inside the OB Truck where our A1 Audio Op can talk directly with them. In the future we are going to either create a button panel inside the truck or just use a StreamDeck/CompanionApp to give us a button that will activate our Intercom System on the Talkback Channel of the TF. This will allow our Director to talkback directly with the commentators. This is useful when we have minimal staff/crew on a show.
