What is Direct Metal Mastering?
In record pressing terminology, Direct Metal Mastering involves cutting a groove directly into copper metal. Stampers are plated directly from the DMM Copper Master, eliminating two of the three plating steps required for lacquers. DMM Mastering produces records with lower distortion, superior high frequency response, longer program times and quieter surfaces than mastering on lacquers. This creates a “brighter”, more pristine sound.
