- The turntable is driven by a 3-phase, 6 pulse, inductance motor,
with 8 pole Neodymium magnets and 3 integrated Hall position sensors.
- The electronic controller uses a high performance microcomputer,
optimised for motor control allowing very and accurate and stable speed control,
including 33.3, 45 and 78 rpm. This design incorporates a 4 layer surface mount
technology pcb with on-board user adjustable speed variation control.
- The Model 30/2 is available in two formats:
- MODEL 30/2 equipped for but not including SME precision pick-up
arm.
- MODEL 30/2A with matching SME Series V precision pick-up arm.
- Complete with a comprehensive set of tools and equipment
including Height Setting Gauge, Ø300mm Stroboscopic Disc, Reflex Record Clamp,
Record Spindle Washer, Soft Cover and Operating Instruction Manual.
- Dimensions: 450 x 350 x 220mm.
- Packing: Substantial wooden case with internal fitments
- Net weight with power supply: 42,0kg
- Shipping weight approximately: 58,0kg

With its many original design features the Model 30/2 is a unique turntable.
There are no critical adjustments or setting up procedures. Its immaculate
construction and finish stem from facilities and uncompromising quality control
which have made SME a byword for engineering excellence. Judged by Germany’s
AUDIO 'the best turntable of all time' the Model 30/2 can be for the fortunate
owner of an analogue collection the key to lasting musical enjoyment.
SME have built pick-up arms for more than thirty-five years and the design and
engineering experience gained has been applied in the Model 30/2, a precision
turntable created to compliment the SME Series V regarded by many as: 'the best
pick-up arm in the world'. In common with this arm the design of the Model 30/2
takes special account of sonic considerations and with equipment of comparable
quality can provide a listening experience that allows L.P. sound to be
re-assessed. Detail, resolution, and neutrality are of a new order with a
dynamic range that does justice to the original sound.
The laws of physics decree that the higher the mass and stiffness of a body the
less it will flex and vibrate - and this is reflected throughout the Model 30/2.
The sub-chassis is machined from 19mm thick aluminium alloy plate and weighs
approximately 17kg while the base with its four supporting pillars adds a
further 16kg. This offers the high mass and stiffness required for uncoloured
reproduction further aided by efficient extensional damping of both components
to reduce the amplitude and duration of their vibrational modes. In conventional
turntables metal supporting springs often contribute significantly to
colouration. Sometimes even their size and nature can be identified by an
experienced ear!
The unique suspension system of the Model 30/2, however has no sonic footprint,
it hangs the sub-chassis on ninety-six strands of rubber in the form of
forty-eight purpose moulded 'O' rings. An ingenious method of anchorage allows
them to be removed or replaced instantly, should this ever be necessary, even
while a record is playing!
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,
allowing the user to make record and arm placements with total confidence. 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.
Built-in locks one at each corner of the sub-chassis, enable the suspension to
be secured and automatically sealed for transport.
The moving parts of a fine turntable are of paramount importance. The spindle of
the Model 30/2 is 170,5mm long and 19mm 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 30/2's excellent dynamics and
pitch stability are largely the result of the immense care taken in the design
and execution of these components.
The platter 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.
Dowels ensure positional accuracy so that if more than one arm is in use the arm
mounting plinth can be quickly interchanged.The powerful electronically
commutated motor is 'cogging-effect' free and virtually vibrationless by reason
of its 2,5kg weight. It is isolated on urethane mounts and adjustable for
accurate belt positioning.
It can be fairly claimed that the engineering of the Model 30/2 is unique in a
turntable. In the quest for perfection even the stainless steel motor pulley has
received detailed attention. It is crowned to ensure belt centrality, concentric
within +/- 2,5 microns and secured to its precision ground tungsten steel shaft
with twin grub screws to maintain rotational balance. From this the drive is
transmitted via a ground rubber belt to a 209mm sub-platter weighing 2,3kg. This
is extensionally damped and incorporates four captive transit screws allowing
the main spindle's vertical thrust bearing to be off loaded for safe transport. |
