Pro-ject Audio Systems RPM 5.1
‚¬ 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.
‚¬ 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.
