Discs are carefully cleaned then transferred using styli from the Expert Stylus Company, an SME 3009 Mk2 arm and Shure Cartridges.
Stylus selection is essential for 78 rpm discs where groove dimensions vary.
The transfer signal is digitised using a high quality A/D converter to produce the Archive Master file. This file is the most accurate digital copy possible of the analogue original, and is the digital reference for further work.
Disc transfer is usually followed by restoration work to remove the clicks and crackles. Bandwidth limited recordings and broadband tape hiss interact making the extent of restoration dependent on final requirements.
