What is the function of the R12 (10 K)
May the ‘GND’ connected with the order side of the R12?
To connect the ground of the circuit with the chassis ground. No, the ground must always be connected as directly as possible (low resistance), so the GND must be connected as directly as possible with the central ground point (star point) of the rest of the circuits connected to the K8084.
What will happen if I remove the R12 between the ‘GND’ and the ‘chassis ground’? If nothing will happen, what is the function of the R12?
That is unpredictable and depends on the other circuits and their wiring.
To connect the ground of the circuit to the chassis ground in a safe way.
Hi,
The purpose of R12 is mainly this: (Correct me if I’m wrong).
Firstly…to tie down GND…–> avoiding hum
Secondly…to avoid ground loops
