Abbey Road's world-renowned engineers have been cutting grooves into discs since the studios first opened their doors in 1931. This record was pressed from a master cust using a precision technique known as half-speed mastering. The procedure requires the source master and the cutting lathe to run at half speed on a specially adapted Neumann VMS-80 Lathe.
This rare and specialized technique transforms difficult-to-cut high-end frequencies into relatively easy-to-cute mid-range frequencies. The result is a cut with excellent high-frequency response and very solid and stable stereo images. In short, half-speed mastering produces a master of the highest quality that enables the pressing plant to produce a superlative record.
