I'm working on the specifics of floating a dedicated DAC I have to a high voltage and aside from the power supply I need to make sure that the connection between computer and dac is safe. The interface I use is USB communication between computer and dac for music playback.
I am wondering since laptops are floating if I connect the usb cable on the computer to the x-hundred volt from earth referenced outlet on the dac if it would be safe. From my understanding the laptop should be okay but it would also be referenced to the earth referenced voltage of the DAC meaning the entire laptop circuitry would now be at the same reference?
