Manual turntable 

Product information

 

Turntable 

 

A quiet running AC motor with a two-step pulley drives the platter's outside edge via a belt. 

 

The transparent acrylic plinth stands on three height-adjustable Sorbothane

®

-damped aluminium cones. 

A supplied spirit level allows easy adjustment. 

 

The motor is mounted in a separate metal housing to eliminate vibration transmission. 

 

The resonance-optimised platter is a sandwich construction utilising an acrylic platter weighing 3,5Kg 
and a brass record puck. 

 

The inverted bearing uses a stainless-steel axle carrying a ceramic ball on which the ceramic bearing plate runs. 

 

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  Pro-Ject 9cc

 

 

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.
