I normally refer to them as domestic and GPO, as do most in TV. The
younger lads soon learn. ;-)


It's precisely because the term "TRS" applies equally to both gauges
(and indeed to 3.5mm 'stereo' plugs for that matter) that I find the
term so imprecise as to encourage ambiguity. I still don't understand
why the recording and broadcast industries don't use the clear &
unambiguous terms "A gauge" and "B gauge".

Probably because A and B are used for so many other things. The TV
convention of calling them domestic and GPO worked just fine in the UK. A
different thing from using the official terms.

I wonder why you call them "domestic", when stereo
or balanced line on jack is rarely found on domestic
equipment - headphone outputs being the exception.

In music we use the term "balanced jack" (add plug, if you like:-)
when it is obvious you don't mean a patchbay (GPO) type.
