[Sursound] Does "gravure universelle" (universal engraving) mean Ambisonic?

[Martin Leese]

Hi All,

There is an used LP on offer on eBay which
is described as Ambisonic, but which is not
included in the UHJ Discography. The LP is
on the Erato label, STU 70221. The cover
says the LP is "gravure universelle", which
Google translate says means "universal
engraving". Is this LP Ambisonic?

The LP is on offer here:
https://www.ebay.ca/i/153041669368

The UHJ Discography is available here:
http://www.surrounddiscography.com/

Many thanks,
Martin

I’m not aware that Erato ever produced UHJ. Gravure universelle appears on many/most/all of their recordings… I’ve never grokked its significance.



But, generally speaking, I do like Erato. I’m contemplating their 50 CD box set…

Erato "gravure universelle"

"Gravure universelle" was used during part of the 60´s
to describe a Stereo LP disk as being compatible
with playback using a mono cartridge.

This used the elliptical filter in the Neumann cutter
set to 300 Hz.

Then all Stereo information below 300 Hz was mono.

Thus there were no 45/45° or vertical cutter movement
for out of polarity information below 300 Hz.

And it was claimed that this type of cut was playable
using a mono cartridge.

It came into use for a couple of years after the record
companies stopped supplying mono and stereo LP
versions of their records.

My own thoughts is that this type of record had some part
of the grooves mangled by the mono cartridges being totallly
rigid in the 45/45° and vertical direction but played with lots
more distortion than necessary.

But that is history now.

Ah yes…of course :-)   Though my latest Erato LP is from 1979, and it still says Gravure Universelle, just in case anyone out there still wasn’t sure, I guess.

It means "stereo compatible" (i.e. stereo recording, playable with a
compatible cartridge that has compliance in the vertical direction.)

In another list for a different version of the same LP, no mention is made
of Ambisonic (http://www.hornet.hr/HRec.asp?gAnr=3594). Has the seller on
EBay simply made a mistake or does he know something? Unfortunately the
images of the sleeves are not good enough on either site to read the notes.
