That doesn't sound good Dave.
I've had this one for a couple of years but not used much.
I have to use headphones due to an intolerant partner so the XenyX is to combine 2 sound sources.
Focusrite + Katana.
I had the 5 channel Xenyx for several years but eventually the main volume slider wore out.
Couldn't replace it so ended up chucking the thing for an el-cheapo Chinese one that's more modern.
cheers, Mark.
