If you only have 3 (8 Ohm) Speakers and want to hook them all up, you will need to balance the impedance of the sides or you will be too loud on one side and not loud enough on the other. This will cause your amp to work harder on one side. (Not Good)
I did not see the speaker A and B in the instruction manual.
Because of that, I will state the following.
I would not recommend that you hook up anything that is unbalanced. I would use just a pair in two channel mode (This would give you an 8 Ohm load on each output). The manufacture recommends a 4 Ohm load for the best output of this amp. But the most important thing to remember is that your speakers must be able to handle this much power or the speakers will be permanently damaged.
This amp has Protection to cover: Full short circuits, Open Circuits, Thermal and HF protection, and stable into reactive or mismatched loads.
You could hook up all three speakers and the amp will work, but, I would not recommend that type of hook-up.
I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

Those specs would be right - I have this same board but the amp was fried by a previous owner. I pulled the amp board out and tossed it and use the mixer now to drive an external amp. Great board. This amp is rated at 1200W "peak", bridged into an 8ohm load. That would equate to about 900W RMS bridged into 8ohm or 450 per side into 4ohm loads per side. You can't daisy chain all 4 speakers....impedance would be too low. You can run two of your 8ohm speakers per side - that results in a 4ohm load per side for the amp. That would give you amp delivery of 450W per side. Your speakers are rated to handle more than that so you're fine. For the record.....you could run one speaker per side no problem....just lower power output.
