So I have a dedicated DAC that I want to plug into one of my amplifiers but I want to direct couple it.
The input of the amplifier is referenced at -220v.
The DAC uses opamp servos to eliminate the DC offset at its output so what happens if I connect the ground pin of the DAC to a -220v supply?
This should effectively shift the ground reference to match the input bias voltage of the amplifier but I wonder is there some potential danger to this?
The DAC is quite expensive and I do not want to attempt this unless I am absolutely sure.
