I have a cabinet and i want to connect a pc with a jpac to it. The only problem is the qsound amp in the cabinet doesnt work unless an acutal jamma board is plugged to the harness and the jpac doesnt draw power. The amp draws 12volts from the power supply and comes on but it wont amp the signal unless a jamma board is connected..
I connected a broken cps2 A board with the fan cut off and that was sufficient enough to power the amp. I connected a broken umk3 board to the harness and that also activated the amp. So my question is whats going on and how can I duplicate it.
