I could do with some help. We have 100' of microphone cable from
around the 1960's (together with an old ribbon mic and transformer).

The ribbon mic + transformer are not sufficient for our needs and I
bought a modern mic which has XLR type connection. I thought the
cable we had would fit but the cable connectors are a little larger
and have a collar which the modern mic doesn't have.

Did the standards change? Were the old connections proprietory or
standard? How do I get from one to the other?

Thanks for any advice.

Dave, with swapping the pin config I think the hot/cold got swapped too.
XLRs are normally:

2 hot

Although (just to be contrary) some older US gear has the opposite phase

Yes. Sorry about not correcting that too.

The idea of that pin configuration is being able to link 1 (screen) and 3
(cold) easily for unbalanced connection. I think.

Indeed - but not good practice, when you may not be able to see or check the

Back on topic, what you have sounds like a Reslo connector, used by them
and Grampian (IIRC) and a few others in the 1960s and 1970s.

They're identifiable thus:

- the pins are fatter than those of XLRs, but still in a fairly even
triangle

- there's a clamping ring with a screwthread, and

- a fat indexing lug on the side of the connector (around 1/16"), and a
slot cut in the side of the mic receptacle (not a groove per XLRs).

It's just possible that it's a Coles connector - that has the three pins
in a flatter triangle, almost a straight line. There's no clamping ring,
but a slot at right-angles to the connector (there's a pin in the mic
that catches in this to lock the connector in place.

The Reslo/Grampian style were common in the BBC and elsewhere for
lower-grade mic uses such as talkback. You often found them on the end
of goosenecks. Mics using that connector were in production well into
the 1980s, pretty much all were unpowered, moving coil.

The Coles ones are still current, for a very small range of mics
(4038s), as they're retro-styling and buyers like that consistency.

As others have suggested, you can simply cut the cable and insert XLRs
to extend it or shorten it as much as you wish.

Ribbon mics were often made to 30 Ohms. This was for two reasons: it was
an early mic impedance standard, because it worked well on long
twisted-pair cable runs (lower losses), and, because ribbons have an
extremely low resistance, the impedance-converting transformer at the
mic end could be cheaper (the bigger the impedance change in one jump,
the harder it is to make a suitable audio-grade transformer).

Prior to XLR ubiquity, BBC studio wallboxes used to use Cannon EP-8
connectors for mic cables. The eight pins included connections to an
impedance matching transformer built into the wallbox, specifically for
low-Z mics, so the mixer only saw around 300 Ohms. So the mic cable
wiring went to different pins on the EP-8 depending on its impedance!

If your (Reslo?) mic still works, there's a good market for it on eBay,
but you'll need to sell it with the transformer, otherwise the buyer
will probably wonder why the output is low and covered in hum!

Wouldn't that correctly be called an STC connecter? Coles being the later

FWIW, that connector is called a thistle at the BBC as it first appeared

In the early days of XLR, they were used in the conventional way. Ie, the

Yes. There's one on the 4021 I own. Time was when they were 'bowled' up

Well, inaminate objects don't _have_ sex but they can be described as
having a gender which is a more polite reference used as a matter of
convention, even though the terms male and female aren't normally
associated with the word gender when applied to people (masculine and
feminine are the normal adjectives in this case).

The mixed use of gender with male and female emphasizes the fact that
it's objects rather than people. Also, you'll find that components
catalogues will use 'gender' for this purpose without any mention of
the word 'sex' (other than perhaps machine translations from Chinese
or Korean catalogues).

Words have gender, people have sex.

So you can no longer refer to the male sex? Or a difference between the
sexes? It now only refers to the act?

Hmm. Bad choice IMO - I've seen a lot of people sing the praises of the
BS1363 scheme, but IMO although it was good at the time it was devised,
it is now far too big a connector for the vast majority of the time,
when there are far more devices that take well under 1A than those
needing anywhere near 13. (And I've never seen a BS1362 fuse rated below
2A, and you can't get less than 3A in most places.) (And yes, I know the
"it's to protect the cable" line.)

I suppose, _if_ you're going to standardise on one plug for everything,
even though this makes most of them far too big, you've got to do so,
though I'd have chosen something other than BS1363 - IEC320, or Schuko,
or ...

One of the worst things about BS1363 is that, in its default form, if
you just leave a lead lying on the floor, it is more likely than not to
settle with its pins up. Just waiting for a bare foot to come along. You
only have to tread on one ONCE to know how bad it is.

As for how long it will take RSA - well, I suppose one could say it's
_just_ about reached universality here, and we're a more prosperous
nation than a lot of RSA ... (When did it come out - 195x? [I think the
"shrouded pins" bit was 197x.])

members of society least likely to sustain themselves or succeed, are
rewarded with goods and services paid for by the confiscated wealth of a
diminishing number of producers.

When I was there I worked for a German company. The factory was wired
with German sockets throughout.

A lot of hotel rooms I've stayed in there, have shuko sockets on the
walls above the desks etc, alongside the 15A ones. And wall warts and
phone chargers etc that are sold and supplied there are normally 2 pin
shuko style.

So as JPG suggested, would make more sense to migrate towards shuko,
rather than BS1363

In TV, we use 4 pin versions for low volt DC.

But not really a problem using the 3 pin for something like this.

It was much more of a problem when some of the lighting rigs in TV
studios
started using 3 pin XLRs for their control circuits.

Those should be 5 pin, but the bottom end of the market felt 3 pin were
more easily available.

And lighting can borrow/steal cables from the sound dept!
