As you walked into this room, the left wall and work benches housed a multitude of ¼” open reel recorders (Revox, Ampex and Scully if memory serves me) and audio cassette decks, some basic analog processing gear along with a few patch bays for connecting one device to the other, like an old school telephone switchboard! Here, we assembled promotional cassettes, market specific, for the sales staff as they shopped for new business. Maybe the target was New Car Sales, so the sales rep would have reviewed the library for similar ads, collected those reels of tape with a list of the various ads they wanted transferred to the cassette tape to give to the new prospect. We did the assembly one cut at a time, making sure the overall sound and loudness were the same basically, and the start and end of each track sounded correct. This task, in this very room became the seed of everything else I would eventually learn.
