An internally damped precision tonearm of highly polished stainless steel provides sparkling uncoloured reproduction offering pivot-stylus dimensions covering virtually all turntable requirements.
The M2 Series tonearm is available in 9, 10 & 12 inch versions and offers at reasonable cost, meticulous build quality with all the most important features including lightweight stainless steel tonearm, detachable magnesium headshell with azimuth adjustment, tungsten balance weight, superb quality ball race bearings and a level of stiffness and rigidity to suit all types of cartridge.
These precision made tonearms embody well tried SME principles and are suited to a broad range of cartridges including those of medium and low compliance.
The headshell is pressure die-cast in magnesium for lightness and rigidity. A collet of ingenious design affords ‘one-piece’ rigidity and allows azimuth correction to be made before final tightening.
Additional Information
Build
The M2-9 shell is pressure die-cast in magnesium for lightness and rigidity.
Series M2-9 is the standard arm having a pivot-stylus dimension of 233.2 mm (9.18”) and will therefore be the one most frequently used.
Series M2-10 is identical except that the pivot-stylus dimension is 239.3 mm (9.42”) a difference that suits the layout of some decks.
Series M2-12 has a pivot-stylus dimension of 308.8 mm (12.16”). Distortion caused by lateral tracking error is at least 25% less than possible with a nine or inch arm. However effective mass will be typically 12.0 grams. Also, a turntable designed for 12-inch arms must be selected.
Damping
The internally damped tonearm of highly polished stainless steel provides sparkling uncoloured reproduction. A unique single element balance system caters for cartridges weighing 5 to 12 grams. After balancing tracking force is applied by forward movement of the weight ensuring the lowest system inertia. The weight moves on a precision screw thread with backlash eliminator allowing exact setting of vertical tracking force.
Adjustments
A collet of ingenious design affords ‘one-piece’ rigidity and allows azimuth correction to be made before final tightening.
1.0 gram per revolution tungsten weight sub-graduated 0.25 and 0.025 gram moving on a precision screw with backlash eliminator.
