Ariston RD 11S PC

The Ariston RD11S PC is a refined version of the classic Ariston RD11S, a highly regarded British belt-drive turntable from the 1970s. It builds on the RD11’s design with advanced bearing and suspension technology, delivering excellent speed stability, low noise, and minimal vibration.

Key Technical Features

• Drive System:
  Belt drive powered by a 24-pole hysteresis synchronous AC motor mounted on a silicone isolation subframe.
  This motor design ensures smooth, quiet, and stable platter rotation with minimal wow and flutter.

• Speeds:
  Supports 33⅓ and 45 rpm playback speeds.

• Platter:
  Two-piece precision ground and balanced platter weighing approximately 9.5 pounds (4.3 kg).
  Heavy platter provides high rotational inertia for excellent speed stability.

• Main Bearing:
  Precision PTFE (Teflon) cushioned main bearing shaft offering ultra-low friction and self-lubrication.
  This technology contributes to some of the lowest rumble figures measurable in turntables of this era.

• Suspension:
  Free-floating subcradle suspension with a low-mass circular tonearm board and platter mounted on steel coil springs with polyurethane dampers.
  This unique suspension system minimizes feedback and stylus bounce, even on severe floor vibrations.

• Tonearm Compatibility:
  Available with SME, Grace, or blank armboards, allowing use of high-quality tonearms such as the SME 3009.

• Construction:
  Teak plinth with plexiglass dust cover and friction hinges.
  Total weight approximately 13 kg.

• Performance:
  Wow and flutter: approximately 0.03%.
  Rumble: around -74 dB weighted.
  Known for very low noise floor and excellent speed stability.
