Here’s an update…
Everything is setup the way it should be… Channels 1&2 seem to do the same job as 3&4, 5&6, 6&7 and also 7&8…. I have tried all different channel combinations (got knows why there’s 8 channels when there’s only one (single channel) input and two (headphones and RCA) output.
I setup with the headphones on my ‘primary soundcard’ (being my laptop) but that is horrible sound and is muffled etc.
The PFL button is lit up (I do have some experience lol)
