特點
* The 12in construction with thin walled stainless steel tone-arm takes
advantage of the reduction in maximum tracking error/distortion afforded by
the greater arm length when compared with 9in models.
* S2-R Aluminum shell detachable and interchangeable without disturbing
cartridge or wiring.
* Double draw-in pin bayonet fitting design ensures a rigid junction with the tone-arm.
* Unique headshell to tone-arm coupling readily allows cartridge azimuth adjustment.
* Internal constrained layer damps minute residual vibrations making tone-arm
acoustically inert.
* Stainless steel cross shaft, ground and thread ground. Carried in a substantial
yoke on 10mm precision ball races.
* Stainless steel vertical shaft, ground and thread ground, with integral 16mm
diameter flange to couple shaft and yoke.
* 23mm diameter steel pillar, heat treated, ground and honed, carries two
17mm precision ball races, widely spaced to resist tilt.
* Anti-skate control operates through Anti-Skate weight and filament, adjustable up
to 5g VTF.
* Lowering/raising control gives smooth positive action. Height of lift can be adjusted.
* Thumbwheel (Vertical tracking angle VTA) height adjustment.
* Bedplate affords +/- 12.0mm movement to facilitate (Horizontal tracking angle HTA)
adjustment.
* Base slides on bedplate for horizontal tracking adjustment with double
null-point protractor.
* Tungsten-alloy balance weight inserts allow 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 applied in 0,5g increments via rider weight
and graduated wayrod.
* Fluid damper FD-M2 is available as an optional extra.
* Alignment protractor designed to provide HTA settings with the greatest accuracy.
* Internal wiring in LCOFC.
