Product Description
Based on the award-winning SA1.2 tonearm, the Sorane SA-1.2BCS adds additional features for the vinyl enthusiast. Silver internal wiring for superior signal to noise ratio. Silver headshell cartridge leads. The SA1.2BCS offers the choice of either positive or negative balance (convertible centre of gravity), via two alternate counterweight stems (the first tonearm ever produced with this
feature in the world).
■ What is “positive balance”? The position of the counterweight shaft is below the centreline of the vertical bearing, moving the
centre of mass below the fulcrum point.
■ What is the outstanding feature of “positive balance”? Unconditional stability, with the tonearm, always returning to the
same resting location.
■ What is “negative balance”? The position of the counterweight shaft is slightly above the centerline of the vertical bearing, moving
the centre of mass above the fulcrum point.
■ What is the outstanding feature of “negative balance”? The tonearm automatically compensates for warps without the aid of
extraneous devices, such as springs, servos, etc..

As shown in these photos, SA-1.2 BCS is equipped with 2 counterweight shafts, one is “Positive” shaft (Installed, upon delivery of the product), while the other is “Negative”, which are replaced
interchangeably by your hands with attached Allen key.

Sorane Tonarm Range Shared Features:
CNC, Machine-tooled and hand-assembled by skilled Japanese craftsmen. This highly skilled and delicate hand-assembly
differentiates Sorane tonearms from mass-produced Japanese tonearms. With standard quality goals, high-volume production
tonearms are manufactured by die-casting and semi-automatic assembly line processes, to keep production costs low.
Gimbal-bearing designs for excellent bass, dynamic sound and imaging, as well as unconditional azimuth stability (which is
the biggest problem for conventional uni-pivots bearing).
Tonearm wires run through separate aluminium tubes inside the arm, maximising stereo separation.
