I’m trying to use the soundboard for my school’s One Act Play. Everyone that could use it have graduated, and I’m trying to play our sounds through it. I tried using the ST3 in, which is a headphone jack, and I tried to use the one below the words “Qu-Drive” (the 1/4th jack) and neither seem to work unless I’m doing something wrong. It’s a Macbook if that helps.
ST3 is an input jack that you could connect to the headphone output on your computer.
The larger 1/4 inch jack is the mixers headphone output jack.
ST3 may need to be patched/assigned to the ST3 fader, you can do that from any channels assignment patch menu from the pre amp menu screen. You want ST3 set to local.
You could always connect the computer to the either ST1 or ST2 on the back of the mixer.
A digital mixer of any kind that has had lots of people using it may have some interesting settings and routing configurations set up!!!
