Consumer line level standards? Surely you jest!

IEC might have some recommendations, and there's a DIN standard for a
5-pin connector that looks like MIDI connector (duh - a "DIN plug" )

The -10 dBV "standard" is pretty much a product of the '80's home
studio gear, which was pretty much led by TASCAM.

Just for additional explanation: "DIN" stands for "Deutsche
Industrie-Norm" (German Industry Standard)

There are DIN standards for a lot of things, not only those connectors
;-) Germans love rules more than anything else.

BTW: I think the 5-pin plug for MIDI is actually older than MIDI,
before it was used for audio-plugs. Those can be found in quite a few
older (70s) hifi-amplifiers.

Indeed, I have a Tandberg radio with a DIN jack output for external
speakers.

Sure it wasn't a DIN speaker socket? A rather rickety arrangement
with 3 holes. Depending on which way round the 2-pin plug was
inserted, you could mute internal speakers.

DIN connectors came in all sorts of configuration. The 180 deg.
5-pin was only one of them, just as there are many XLR connectors
other than the common 3-pin one.

I knew it was a German acronym, but not speaking the language, I don't
try to remember the full name. Over here, it's spoken as "dinn" and I
suspect most people don't know that it stands for something.

Oh, yes. Fully the equivalent (and more) of the IEEE, AES, and IEC.

Definitely. MIDI is a relative newcomer. Very early MIDI devices used
an XLR connector, but when the industry got together to write the MIDI
standard, they chose the 5-pin DIN with the key wherever it is on that
version. There are different orientations of the key that tend to keep
you from using the wrong combination, and there are also variations of
the number of pins in that pattern and size. I have a Revox A700
recorder that has one of those connectors for stereo inputs and
outputs, and while I've never used it, when they were available, I
picked up a breakout adapter from audio 5-pin DIN to four RCA jacks.

Incidentally, I think that the "industry agreed upon" nominal level
for that audio DIN connection was around -20 dBV. I don't know if
that's in a DIN document, though.

Yes, it's on the side of a Tandberg portable FM radio that I bought the
day I took over management of AWHQ. I needed to know what the radio was
playing. <g>

It is the only use of a DIN plug for speaker feed that I have ever
encountered.

I have a few B&O plugs & cablesets in the garage if anyone is desperate.
