NTA is short for New Transatlantic (some releases list both NTA and New Transatlantic, current digital reissues use the joint logo and the name "New Trance Atlantic")
The label was active between 1993 and 1997 and functioned as the vinyl division of Digitrax Int.. The last few release were either listed ambiguously with a contact at "Delirium Köln" or the very latest ones with being a division of Kompakt Schallplattenladen.
