Seems to me that when wiring balanced connectors, the live end should contain a female socket and the receiving connector the male. This would tend to prevent human contact with electric output.
However, I don’t see any consistency in this. Perhaps low voltage analog signal is not considered worrisome.

A typical consumer unbalanced audio device would have an output around 316 mV.
I read it here: https://www.tvtechnology.com/opinio...balanced,dBV (referenced to 1 volt) or 316 mV.
I don't find that information shocking! 🙂

Indeed!
At low levels, the inputs are female to prevent buzzing & humming when touched accidentally. The outputs are protected with a resistor, most often between 10 - 1000 ohms.
At main amplifier levels, the voltages can rise up to 100V or more, so better protect them from being touched accidentally with a female socket. The loudspeaker, being passive at its own, has corresponding male plugs.
Nope.
The standard connection for balanced audio connections using XLRS is male for output and female for input.
See XLR_connector
"The standard signal flow for audio in XLR connectors is that the output is a male connector and the input is female. In other words, the pins on the plug point in the direction of signal flow"
and for completeness, the pinout is:
This is the configuration that you should use if you wish to be compatible with the AES standard. And all the commercial gear out there - home and professional.

Some mics need 48V for do its job. I never knew about a guy shocked with 48V, but one never know...
why do people want to change a long established standard?
i get the logic when we're talking AC power, but signal circuits?
if the danger is exposed pins than be "ultra" careful with standard RCA connectors....RCA jacks... come to think of it, there's a connector type that is a candidate for replacement!

The broadcast world used balanced line for analog and digital audio connections.
The refrain "audio goes in the direction of the pins" describes the sex of the
connector which is opposite of your description. We got some Sony BVW-7x
machines for the Japan market that had the reverse connectors installed. It
took the tech a fair amount of time to convert them to North American sex.
Nominal analog level is +4 dBm with some houses running +8 or 0 dBm as
the 0 reading on the meters. + 4 dBm is 1.224 V rms and nobody ever worried
about touching of shorting the signals. Digital signal levels are 1 V p-p.
I calibrated Henry Matchbox audio levels to +4dBm on the balanced side and
-8 dBu of the unbalanced side.

The 48 V phantom supply uses 6k8 (6800) ohm resistors to feed the +48V power
into each phase. MAYBE you could feel that if you were salty/sweaty...

That 48V is present on the input of the module and input end of the cable and is therefore a female connector, not male. The microphone does not generate 48V on its own.
For pros (and not so pros) doing audio setups at remote locations, the say is:
"Fsomething the truck"
On one setup, an assistant ran a 500 foot cable the wrong way. And didn't unreel it correctly, so it had twisted loops when we reran it.
