I'd play with it on Batteries - maybe. But, it'd be plugged in before I hit "Record.'
Im my experience. You need 'constant current' for things to 'work right'.
The Battery would have to be near fully charged. I don't fancy changing 1/2 used batteries.
About IK. My everyday MIXER is IK's iRig Mix. Proper BASS EQ.
I am also familiar with their 'noise' complaints.
