SME Model 30/12 MK2 Turntable

Description

Created as a companion and to compliment the Series V-12, the Model 30/12 precision turntable enjoys all of the features associated the Model 30/2 precision turntable. The differences are merely ones of scale. The suspension now provides 60 purpose moulded O rings supporting the sub-chassis, which has been increased in thickness by some 16%, on one hundred and twenty strands of rubber. The main chassis has received similar attention but in this case the thickness has been increased by 19%. Small differences but necessary to afford the increased rigidity required to ensure acoustic neutrality.

The moving parts of a fine turntable are of paramount importance. The spindle of the Model 30/2 is 170.5 mm long and 19 mm diameter. The massive sealed housing and individually fitted sintered bronze bearings in which the spindle runs are also of the generous proportions needed to ensure that the 330mm diameter platter weighing 7kg is adequately supported. The Model 30/2s excellent dynamics and pitch stability are largely the result of the immense care taken in the design and execution of these components.

Features

Tonearm Pairing
SME have built pick-up arms since 1959 (60 years) and the design and engineering experience gained has been applied to the Model 30/12. A precision turntable created to compliment the SME Series V regarded by many as: the best pick-up arm in the world. Dowels ensure positional accuracy so that if more than one arm is in use the arm mounting plinth can be quickly interchanged.

Designed to compliment the Series V-12 tonearm/p>

Suspension
No sonic footprint, the sub-chassis is hung on one hundred and twenty strands of rubber in the form of sixty purpose moulded O rings. An ingenious method of anchorage allows them to be removed or replaced instantly.

Damping
Sub-chassis motion is disciplined by four fluid dampers, one in each of the supporting columns. These eliminate overshoot and give almost zero Q recovery. The isolation needed to prevent acoustic feedback is bridged by the resistive coupling of the damping fluid through which unwanted reacted energy is conducted away to ground. This function is adjustable through trimmers which can be used in conjunction with a gauge to give recommended settings or varied to suit individual conditions.

Platter
330 mm (13) diameter weighing 7.5 kg (17 lbs). The face is machined with a fine scroll found to interface better than a plain surface. A substantial reflex clamp ensures maximum contact with the platter even when severe record warp is present. The sub-chassis/arm mounting board interface is extensionally damped and the mounting board is reversible to allow mounting of nine inch pick-up arms when necessary.

Motor
The turntable is driven by a 3 phase, brushless outrunner motor with 8-pole Neodymium magnets and 3 integrated Hall effect sensors and virtually vibrationless by reason of its 2.5 kg (5.5 lbs) weight as well as being isolated on urethane mounts that are adjustable for accurate belt positioning.

Speed Control
The electronic controller uses a high performance microprocessor, optimised for motor control. Closed loop speed control is implemented using a proportional plus integral (PI) algorithm. Fine pitch speed adjustment allows increments/decrements of +/-0.01% of selected speed. Speed ranges: 33.3, 45 & 78 rpm.
