Yes you can go in, see and adjust settings and the only thing to beware of is being too aggressive with the compressor or with the Parametric EQ.* Both can cause early onset feedback. You can select either complete band reset or individual channel presets.
* you can also select Quick Setup that will give you a typical Bass Mid, Treble type tone three knob adjustment for those migrating from an analogue desk,.
I will put it on later and dive in more.
