sorry, I searched PDF manuals and forum to no avail.

what is the pin layout of the SHD analog XLR Input and Output connectors?

Pin 1, 2, 3
1=Common
2=Hot/Cold?
3=Hot/Cold?

i.e. have one these "BX1" amplifiers connected,

I have measured absolute polarity for the SHD and can confirm that pin 2 is (+)/(hot)/(in phase) and pin 3 is (-)/(cold)/(out of phase).

thank you, mvs0!
that was quick ;)

dear miniDSP team,
please complete this in the manuals.

Analog XLR Pin assignment:
1=Common/Shield
2=Hot/+
3=Cold/-

(this XLR layout is called "European", the "American" has Pin2 as "-", Pin3 as"+")

thanks

There's only one standard (pin 2 hot).

No, definitely two standards as mentioned above.

No, not anymore there isn't. This was standardized many years ago.
Pin 2 is "hot" and Pin 3 is "cold." Period.
You could find a piece of gear from 1965 that is wired the other way. :)

Sure, the EIA RS 297-A standard may have been published in 1970 but professional audio gear was still wired either way well into the 1990s depending on which market it was targeted at. That may even still be true, I just haven't been involved with that scene since then.

It's really not that surprising even. How do you expect the US to switch to a different standard when all their old gear was to the old standard. The pragmatic approach won, they ignored the new standard in many cases. In recording studios where old gear is treasured rather than replaced I don't blame them.

If you work with such gear there are two standards, if you read standards there is one. I don't blame them for settling on one standard, it had to be done at some point, but even 50 years later the standard is still somewhat aspirational in practice.

Can you post a schematic from a piece of equipment manufactured in the last 20-30 years that is configured that way??

Anyways, the topic question has been answered regards the SHD. I don't see the point in belaboring this any further.

It seems KlarkTeknik DN360F and Emotiva XPA amplifiers are still pin 3 hot! Currently available products.

Emotiva wires their amp inputs wrong...

That said, I wouldn't say the burden is on miniDSP to label pinouts if they conform to current norms. Rather, it's companies such as Emotiva that do it wrong who should be labeling.

Emotiva's information on this is confusing. Their manuals do not specify exactly, but note using the "European standard" regards XLR polarity. But, the "European standard" did indeed use pin 2 as hot/plus and pin 3 as cold/minus. So, it's not clear to me their operation is wrong. Maybe it is correct and they don't understand what they're talking about???

Replace "correct" with "incorrect" in your last sentence and that would be about right for that company.

Here's the official word: balanced output source gear wired correctly, balanced input amps (except one!) wired wrong.

What a horrible mess. :)

Anyways, not related to miniDSP.
