I don't speak any French, so I couldn't read most of what I found when I did a net search for Atoll. But what I could read seems to say that they are selling Technics products that they have enhanced (and marked way up). Those pages clearly say that the Atoll remotes are "a Technics remote with an Atoll plaque on it".

Technics uses the same IR signals as Panasonic. I assume the Technics brand name is owned by the same company as the Panasonic brand name.

I think the confused way Atoll has described their IR protocol is either because the don't understand that part of the technology they got from Technics and/or because they don't want to advertise the fact that they use a Technics remote.
