Trying to get 2 separate out channels on an old Behringer Eurorack 802A audio mixer.

Hi, and thanks for letting me join! I keep going around in circles, even using the manual, so am asking for help.
I've been trying different inputs and outputs pushing buttons and trying to understand the Aux Out, to no avail.
I've even considered the Eurorack is faulty - even though it is very old, it wasn't used much at all, and I've sprayed every knob and button with contact cleaner. It "seems" to be working fine, my problem is most likely: User Error.

Equipment
*Behringer Eurorack 802A
*Windows 10 PC
*Dynamic Microphone (SM-57 or 8) Plugged to Channel 1 via TRRS cable.
*Guitar Modeler (Tonex Pedal) (Mono Out)
*Single (1) Kali LP8 Studio Monitor
*Guitar amplifier
Note: I have the Computer Stereo audio and Mic summed to Mono with a Y Cable into the (1) Kali Monitor.

I would like to:
1. Get the microphone and PC computer audio output into the Main Out to Studio Monitor.
2. Get the guitar processor/modeler to a separate Out (Ctrl Room/Aux Out/Headphone Out?) to Guitar Amp.
Is this possible? I haven't found the magic combination of Ins and Outs that gets me there.
Great forum! Thanks for any advice you may have.

FIXED! I found the magic combination of ins/out and buttons. Got 2 separate channels working now.
Thanks to everyone that checked out my thread!
