SME MODEL 30/2A

Con le sue numerose caratteristiche progettuali esclusive, il Model 30/2 è un giradischi unico. È stato giudicato dalla stampa specializzata "il miglior giradischi di tutti i tempi. Braccio cablato con cavi Van Den Hul (Model 30/2A).




Arm
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’. Dowels ensure positional accuracy so that if more than one arm is in use the arm mounting plinth can be quickly interchanged.

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.

Power
Mains voltages available are 90-110V, 105-125V and 220-240V 50/60 Hz. Please specify when ordering.
