Pro Logic History

What year were the last, supposedly improved PLII devices made? I think the receiver I have was made circa 2012 or thereabouts.

Actually I think it's older than that. Still works good though.

My Rotel pre/pro was manufactured from 2015-2020. But Rotel was/is notoriously late to adopt and adapt to new tech and formats.

That's not necessarily a bad thing, it means they don't participate in all the teething problems when it is bleeding edge.

If what I’ve read is correct, a/v manufacturers can license both the Atmos/Doldy Surround package and the older package with PLII, but understandably none have. Dolby should have made PL II part of the Atmos package for legacy customers.

No, they can't. The patents have expired, so there is no licensing PLII. They can just use it. It's in the public domain.

However, Dolby does not want them to use it.

When the Sansui patents expired they were revitalized by Involve Audio. No one wants to revitalize D PL II.
