DSP grounding

[shizyo]

Hi, just wondering how you guys have DSP grounded? I can see on the diagram there are physical wires that connect the power supplies to the ground on the AC outlet but not with the DSP.
I remember that somebody said that we just need to put the DSP controller on the machine's metal chassis? What if my machine is built up using the MDF and acrylic material? Do I need to use another physical wire to connect DSP to the ground on the AC outlet? Thanks.

Just connect a wire to the DSP case to the PSU and the DC power supply. Of course, all those units need to be connected to the true ground on the AC outlet
