Well then I will have to find a new power supply. >Yes, the DAC outputs have a signal pin and a ground pin. >The encoder board also has a ground pin for each encoder. With only the encoders plugged into the PPMC boards the D-sub connector does not show ground. OK let make sure I am saying this right with only the encoder plugged in and my meter set to ohms, one lead on the D-sub connector and on on the chassis it shows an open circuit. If I plug in the amp to the DAC or the parallel cable my meter shows a dead short. Not that this helps of changes anything I just want to make sure I am explaining it rigth Would there be any benefit to moving all the grounds to one one point, this would be fairly easy to do.
