For best practice, we recommend setting up the system with a consistent grounding reference across all compatible units, and ensuring there is only one grounding reference point in the whole system.
A practical way to test would be:
First set all applicable devices to either FLOAT or EARTH (choose one starting point for the whole system)
Then, if needed, change the setting step by step on individual units to compare performance
This helps identify the most suitable grounding configuration for your setup while maintaining a single reference point
Please also note that when switching between FLOAT and EARTH, make sure to power off the system before changing the setting to avoid any potential risk.
In most cases, this approach helps achieve the lowest noise floor and the most stable performance.
