Pro-Ject RPM 5.1

Table tournante.

 

Manual turntable with 9″ carbon tone-arm

 

Turntable

• Chassis piano-lacquered dark grey

• A quiet running AC motor with a two-step pulley drives the hub and platter via a flat-ground belt.

• The medium density fibre plinth stands on three height-adjustable rubber-damped aluminium cones.

• The motor is decoupled from the plinth to reduce vibration transmission.

• The resonance-optimised platter is a sandwich construction utilising the hub, an medium density fibre platter, a cork mat (a standard felt mat is supplied also) and a screw-down record clamp.

• The platter’s low-tolerance chrome-plated stainless-steel axle runs on a Teflon bearing plate in a sintered bronze bearing housing.

• Central metal block optimises centre of gravity and damps main bearing.

• Connection to the phono input of the amplifier can be made with connecting cables of your taste through the gold plated phono sockets and earth screw. A standard cable is provided.

• External power supply avoids potential electro-mechanical interference.

 

 

Tonearm 9cc

• As an optional extra, the turntable is supplied with Ortofon 2M Red MM-cartridge fitted.

• The headshell and armtube are fashioned from a single piece of carbon-fibre.

• Conical armtube avoids standing wave reflections.

• Inverted tonearm bearing comprises four hardened stainless tips in ABEC7 spec ballraces.

• Rings provide very solid arm bearing housings. The outside ring is open to avoid resonances.

• Design of counterweight effectively counteracts unwanted resonances.

• The counterweight supplied is suitable for cartridges weighing between 6 – 10g. Alternative counterweights for cartridges weighing between 11 – 15g, 8 – 11g or 5 – 8g are available as an accessory part.

• Counterweight shaft lowered to record level reduces cantilever forces and dynamic wow when playing warped records.

• Solid armbase permits accurate height adjustment of armtube and VTA (vertical tracing angle).

• Single-screw fixing of armtube allows rotation for easy adjustment of needle azimuth despite fixed headshell.

• Silicone-damped armlift can be adjusted to suit working height of the arm.

• The internal wiring consists of flexible high-purity copper from the headshell right through to the gold-plated phono sockets.
