I have Bluetooth coming in on ST3. Works fine, routes to the Main L/R. I’d like to send to different set of powered PA speakers which are connected to the Matrix Outs (left/right). I couldn’t seem to do this: the Matrix View didn’t have ST3 as an option for a source, and the Mix/Group Sends tab on the ST3 channel doesn’t have Matrix as an option.
You can not directly send a channel to a matrix….at least in the QU series.
You would need to assign it to mix or group first and then bring it up in the matrix.
ST3 can be assigned to a group or a mix just like any other input channel.
