Charlin also mentioned (with photo) in this paper on history of binaural (first PDF below, page 772).

A current and frequent user of the Jeckilin is ex-Decca engineer, Simon Eadon. Shown are a couple of his sessions.

Many years later, Jecklin inceased the dimensions and spacing for less 'mono-ish' sound at low frequencies (see JecklinDisk PDF).

Jecklin (and baffled, head-spaced omni techniques in general) works best on smaller enembles and/or those without a lot of LF content (small to medium size choirs, and chamber groups). For full orchestra they are best combined with widely spaced omni 'outriggers', or 'flanks'.

It's worth mentioning that Alan Blumlein described the technique of head-spaced baffled omnis in the '30s! (long before Jecklin or Charlin). Best known for the technique of figure-8s coincident at 90 degrees, he was also the first to describe baffled omnis.

Hi guys
A bit off topic but not really if you consider that searching for "only two mics" leads to keep on searching and try things...

So in this spirit I bought 2 PUI5024 electret capsules and just set them up according to the "Simple P48" project : one 150KΩ resistor and a good quality capacitor (I used a Panasonic FC 4,7uF@50v) for use with phantom power and the result is really amazing ! at first audio test (with the capsule not yet installed in the XLR connector so just hanging at the end of a one foot audio shielded cable > just for a first quick audio test to check if I have sound... and I do !)

This weekend I will do some more audio tests to compare with my Line Audio Omni1 pair (voiceover & acoustic guitar something like 5 feet away > ambiant recording) and will post them here asap (in a blind test of course :giggle:)

Thanx to @ricardo who guided me to this project that I didn't know and provided me the good infos & links ;)

To be continued...

[EDIT: Already posted in #262 above as Stephan Paul article]
An interesting academic journal article that covers several devices, including the tete Charlin:
