I suspect something is wrong with my unit.
The volume knob has always been pretty weird, there is no audible volume untill I turn the volume to at least 20, but it doesn't get to a useful level before 40.
That is a minor annoyance, but what is much worse is that whatever is playing out my speakers, seems to feedback into the input channels 1/2. It's not the input routing which is causing this. If I set the main speaker output to other ports than outputs 1/2, such as 3/4, 5/6 or 7/8, then the output is STILL coming out of outputs 1/2 and it is still being fed back into inputs 1/2? So basically inputs 1/2 are unusable. The only workaround to not having the speaker output being fed back into inputs 1/2 seems to be to turn on the alt speaker mode and go into the settings and set outputs 1/2 to alt speaker. But then outputs 3/4, 5/6 and 7/8 stop working, so I can't use those outputs for external effects. If I set those outputs to alt mode aswell, then the main output mirrors onto ALL output ports.
Final workaround is to turn it to alt mode, go into the settings and set speakers 1/2 to alt mode and speakers 3/4, 5/6 and 7/8 to DAW mode. Then finally, nothing is mirrored and fed back into inputs 1/2 so I can use those inputs for my instruments without any weird feedback issues. But the problem with this setting is that it bypasses all volume control, so whatever signal is coming out of outputs 3/4, 5/6 and 7/8 will be EXTREMELY loud, but at least I can use all inputs and outputs with this setting.
Oh yeah, and I can't get Cue A, B, C or D working at all. Does not work. Don't buy this, it may be somewhat cheap, but that's because it's crap. And considering that it is crap, it is not cheap at all. It's rather expensive crap. I'm not considering getting something like an Apollo instead. Hopefully I will be able to use this unit for ADAT expansion, because I do need a lot of inputs and outputs for hooking up all of my gear.
