Platter
The platter is produced from a ceramic oxide powder which is compressed,
fired and diamond ground to size. (Because this platter is as stiff and hard
as sapphire, the only improvement that can be made would me to make it
from diamond.) This is again a first in the industry at volume production
levels. Even so, each platter takes many hours to produce. Expensive detail
design ensures it only sits on three points on the centre hub.
Plinth
The new P9 plinth is made from an even lighter material than the original
Planar which again offers advantages over its predecessor.
The plinth is of a skeletal design. This allows the mass to be reduced and the
rigidity increased in comparison to a solid section construction. All organic
materials used in the production of the plinth and surround are obtained from
sustainable sources.
Motor
The motor is a high specification, 24V twin phase synchronous unit
controlled by Rega's unique and innovative power supply. The motor drives
the computer-numerically-controlled (cnc) machined pulley and sub
platter/hub-bearing assembly via a twin belt drive. Two belts are used so that
any small inaccuracies in one belt will be cancelled out by the second, giving
unusually low levels of wow and flutter. A Mu-metal shield is used to minimise
extraneous electromagnetic radiation interfering with the cartridge.
