Product information
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 Pro-Ject 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.
Dimensions W x H x D: 371 x 145 x 300mm. Dust cover Cover it optional. W x H x D: 460 x 225 x 365mm.
Cartridge: Output voltage 5,5mV. Recommended load resistance 47kohms (MM-input).
