Connecting a single-ended signal to a balanced input

Hi, new here.

Can I connect a single-ended signal to a balanced input without connecting the single-ended ground pin to any system or enclosure ground?

@jandidden : What are you talking about? In what context? Is this an electricity Q? If so, ask your electric supplier.

It is in the context of an audio installation. Single ended audio source connection to a balanced input.

Often you see that one of the balanced inputs (the cold line) is connected to the single ended return line, which normally is signal ground from the source, as well as to signal ground at the receiver end.

I believe this last connection is not required (assuming you have enough headroom), but I'm not sure.
