Still can’t get anything sensible out of my katana 50 into some headphones. Tried both mono and stereo 1/4 jacks and into various headphones (some onaudio a9s, RHA in ears, Apple iPhone standard things).
The mono 1/4 jack basically doesn’t work - just a faint crackly sound, the stereo jack only works when the plug is half in half out, and then only into one side of the headphones.
Thing is, there are lots of questions posted asking how to get a katana working with headphones but I cant see any answers. So I’m beginning to think there’s some underlying thing (you need headphones with some impedence, or some special jack or whatever). It all feels a bit stupid though - plugging some headphones in shouldn’t be complicated.
Next step might be to get some studio monitor headphones that come with cables and jacks - AKH 240 get reasonable reviews at <50 quid. I’d happily spend the money if they work, but I’ll be pissed off to spend it and get no further along
