I was able to find a double mount from a company called PRSTF. They are competitors themselves and have made some sweet stuff in the past.
Oddly enough, with the default tone B sounds, the send it level goes crazy and lights up all the colors. In the custom settings I tried tone A and C and they didn’t make the level unusable like the B tone did. It only disrupts the send it level when the sound is played, but that became a problem doing the last 5 seconds of the countdown when it beeps every second.
Not a huge issue, just something that caught me off guard. As always, test your match equipment before the match!
Here is a link to the mount
