Rega RP10 - Manual (Page 7)

MAGNESIUM AND PHENOLIC - DUAL BRACING
A super lightweight plinth combined with a double brace mounted specifically where the
increased rigidity is required (between the tonearm mounting and the main hub
bearing) forms a structurally sound, “stressed beam” assembly. This design prevents
energy absorption and unwanted resonances which will add unnatural distortions to the
music.
The
RP10 takes our double brace technology to the next level. Not content with an
unprecedented stiffness to mass ratio, Rega has obsessively reduced any resonant
properties by using two different materials for the new stressed beam. The top layer is
magnesium and the bottom layer is phenolic (two of the lightest and stiffest materials
available). Incorporating two different materials into the brace structure lowers their
ability to pick up unwanted airborne vibrations.
Simply put, different materials have different natural resonances. By using two
different materials together, they decrease the natural frequency of each other by self
damping.
CERAMIC PLATTER
The
RP10 uses a custom ceramic flywheel effect platter. The platter is produced from
a ceramic oxide powder which is compressed, fired and diamond cut to ensure perfect
accuracy and flatness across the surface. This new platter features a modified
construction over the previous P9 version with improved coupling to the sub platter
.
