F5 question

1 Attachment(s)

Good People,

In the DIY store F5 boards I'm using
there are 2 groung markings- Why two ?
Do I connect the ground (one or both of them) from the board directly to case earth or to the CL60 which then then goes to eart?

Thank you all
IK

or you can run speaker negativ directly to PSU gnd too.

You always want to use the power supply star ground for the speaker negative and the ground on the board.
