On your master bus click Control Room in the mixer (to the left of Meter), at the bottom click where it says Control Room - Stereo. Lower down, just below where it says Talk Dim Level, you’ll see a button marked “Click”
Ok, I’ve found it. Thanks. I had to click the word “STEREO” in order to see all the other options. If anyone else is having trouble, I’ve circled it in RED.
below above the letter A (which is in blue)
you see an icon of what can only be described as a “small bird eating a pyramid” aka the metronome icon
if that turns blue…voila, there you go !
