Is the 4 pin XLR wiring configuration a standard?

[Duggeh]

I ask because the AKG K1000 uses one configuration (i was told it was this anyway):

1 - left channel live

2 - left channel earth

3 - right channel live

4 - right channel earth

Which I duplicated when i reterminated my Ergo AMT and made a Hirshmann adapter:

pin 1 - no connection to headphone

pin 2 - dotted line - left channel negative (2)

pin 3 - unmarked inside - left channel live (1)

pin 4 - no connection to headphone

pin 5 - unmarked outside - right chennel live (3)

pin 6 - continuous line - right channel negative (4)

...and duplicated again when I replaced the panel and connector on the TakeT H2/TR-2.

Except that the TakeT H2 paperwork, and the sets coming from the company dont use this configuration.

They have 3 as right earth and 4 as right live. The left channel on 1 and 2 is the same.

Have I been given the wrong information in the first place, or is it actually just up to any individual manufacturer? Is there a standard?

This clarification would be important for those who might be using a K1000 configuration pigtail to drive an H2 directly (if the K1000 XLR configuration I've been using is the right one)

Thanks.

3 - red - Right+

4 - blue - Right-

1 - white - Left+

2 - black - Left-

Yep your K1000 info is correct. I just took that from my K1000 manual.

I'm not so sure there is an industry standard though.

IMHO the K1k is the industry standard since it was the first to use the configuration. That's awful that someone else chose to change that now, it'd be like having multiple 3-pin configs to contend with. :|

The fundamental incompatibilities in amplification requirements is perhaps a reason to have a slightly different configuration and to make sure that the fact is known?

That's usually a reason to have a different connector altogether

That didn't stop Precide from sticking a Hirschmann on the AMT even though the jecklin electrostatic used the same connector (and so did the plasmasonic plasma headphone)

Stick the AMT into a Jecklin electrostatic transformer and say goodbye to the drivers because im fairly sure that they'd pick up the bias voltage as a drive signal.

Since when has common sense been the primary concern of anyone involved in hi-fi
