My memory of them suggests that they were just extension speakers provided with selectable programme feeds.
There would presumably have been a rack of receivers feeding them, I'd imagine 100V line with perhaps a 1W transformer and a variable attenuator in each panel.
I might well be wrong, though.
Edit: As Russell suggests, they sometimes had intercom facilities too.
