The Model M2-9R precision tonearm developed by popular demand offers the design and engineering excellence associated with SME in a compact package.

 

As a member of the M2 family this tonearm is built by enthusiasts for enthusiasts and among its extensive features include, vertical and horizontal tracking adjustment, tungsten balance weights housed in satin chromed brass sleeves. Double draw-pin detachable headshell with azimuth adjustment and height adjustment by thumb wheel enabling its use with wide range of both cartridges and turntables.

Additional Information

Build

S2-R Aluminium shell detachable and interchangeable without disturbing cartridge or wiring.

Double draw-in pin bayonet fitting design ensures a rigid junction with the tone-arm.

Stainless steel ground horizontal spindle carried in substantial yoke in lOmm diameter precision ball race bearings.

Stainless steel ground vertical spindle with integral 16mm diameter flange to couple the spindle with the yoke.

The 23mm diameter steel pillar is heat treated, ground, internally honed and carries two 17mm diameter precision ball race bearings widely spaced to resist tilt.

Internal wiring is Silver Litz.

Damping

Internal constrained layer damps minute residual vibrations making the tone-arm acoustically inert.

Adjustments

Unique headshell to tone-arm coupling readily allows cartridge azimuth adjustment.

The Anti-Skate control operates through an Anti-Skate weight and filament and is adjustable for up to 5g of cartridge vertical tracking force (VTF).

The lowering/raising control gives a smooth positive action and allows for the lifting height of the cartridge above the record to be adjusted.

Tungsten-alloy balance weight inserts allow for maximum centre of gravity shift to balance a greater range of cartridges. Up to 38g in S2-R headshell and direct plug-in heads up to 46g.

Precise vertical tracking force up to 5g is applied in 0.5 increments via the rider weight and graduated wayrod.

Thumbwheel cartridge vertical tracking angle (VTA), height adjustment.
Bedplate affords +/- 12.0mm movement to facilitate horizontal tracking angle (HTA) adjustment.
