Hiss noise on SD Recording is so annoying, no matter how the initial volume, gain or master knob is set. It's constant can't get rid of it. Is it possible to remove it? I need to use this feature very often that's why I decided to buy this stuff, but if it's not possible to take care of the problem I must return this mixer as I need a good working one.
I've tried also to record silence and it's still there!
