Forums IMPORTANT: PLEASE READ Paraliminals, Paraliminal Resets, Paraliminal Walkabouts, Natural Brilliance, Sonic Access were tapes recorded in dolby?

LSC, I recieved my tapes recently. Were the masters done in dolby? Usually tapes have a print mark, but these don't mention it. I want to make sure I use the right dolby setting or none at at all to get the sound most as it was meant by your recording studio. Thanks.
