Usarrn, as Audience AR-12 outputs in the US 120V AC, and the PC-1 accepts 120V AC as input, at least in theory, nothing bad should happen. I say "at least in theory" because I have never tried it, and WILL NOT guarantee to you that your system will not be damaged by the experiment. Furthermore, by feeding Audience AR-12 into PC-1, and then PC-1 into the JRDG501, it is possible that you may reduce the dynamic range of your system.
Please note that the PC-1 outputs 385V DC, and this is likely to be incompatible with the Audience AR-12 input requirements. As such, if you plug PC-1 into the wall outlet, and then you plug the PC-1's output into the AR-12's input socket, you are very likely to blow up the Audience AR-12, and perhaps the rest of your system.
Best, Guido
