Pro-Ject RPM 5.1 SE Turntable



Pin It

The aim to better the hi-fi -classic Pro-Ject-1 is achieved with two different approaches: According to the principle of "less is more" we exchanged the rectangular chassis in favour of a radical "drop-form". In addition, the old resonating main platter was exchanged for MDF which is free of resonance. A metal ring is mounted around the main bearing for optimised conductance of unwanted vibrations. The audible benefi ts are amazing. The sound is calmer and richer without losing detail. 

Features:

  • 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.
