My school is doing some renovating, our computer classroom had a sound system. We want to make some minor changes so that the speakers can play sound from PC, and at least 1 AUX at the same time. It would be highly appreciated if someone knows how to connect the system together as we are no audio professionals.

Our system has a commercial processor (top), stereo leveler (middle) and power amplifier (bottom).

We mainly don't know how to connect the commercial processor.
