I’m very new to Allen & Heath products and the SQ-6 and over the summer someone managed to unlink the master fader from the MainLR and the master no longer does anything when moved. I have no idea how it was done but after that happened the LR-mix selection button is now always lit up but clicking it does nothing.
Yes! thank you, the select button was red and once I swapped it to Mix master it turned blue. Although I can’t remember is it always lit up?
The blue light represents which “mix/buss” is currently being controlled. If you are controlling/mixing the main LR mix, then its select button will be blue. If you change to another buss/mix, the select button of that buss/mix will be blue, and the main LR “select” button will not not be lit up.
