The weight moves on a precision screw thread with backlash eliminator allowing exact setting of vertical tracking force. After balancing tracking force is applied by forward movement of the weight ensuring the lowest system inertia. A unique single element balance system caters for cartridges weighing 5 to 12 grams. The internally damped tonearm of highly polished stainless steel provides sparkling uncoloured reproduction. Also, a turntable designed for 12-inch arms must be selected. However effective mass will be typically 12.0 grams. Distortion caused by lateral tracking error is at least 25% less than possible with a nine inch arm. Series M2-12 has a pivot-stylus dimension of 308.8 mm (12.16”). 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 M2-9 is the standard arm having a pivot-stylus dimension of 233.2 mm (9.18”) and will therefore be the one most frequently used.Typical effective mass 9.5 grams. These precision pick-up arms embody well tried SME principles and are suited to a broad range of cartridges including those of medium and low compliance. All M2 arms are equipped to receive an accessory fluid damper FD-M2. These arms offer 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 etc., and a level of stiffness and rigidity to suit all types of cartridge. `The Series M2 embraces three models the M2-9, M2-10 and M2-12 offering pivot-stylus dimensions covering virtually all turntable requirements.
