V15-RS Cartridge  (420-2800)          Features         Faxback Doc. # 16414

Shure has developed a unique process for forming an ultra-thin 0.0005-inch
wall, beryllium tube, resulting in the lowest effective mass of any stylus
shank and highest ratio of stiffness to effective mass ever.  This ratio is
an index of the ultimate contribution to performance of the stylus shank;
the higher the ratio, the better the performance.

A material can be fabricated with different geometries to yield lesser or
greater performance benefits.  The unique Shure stylus construction is
called MICROWALL/Be.  While material may have high stiffness and/or low
effective mass, until Shure developed the MICROWALL/Be process, it was not
possible to take full advantage of the properties of beryllium that provide
superlative high-frequency trackability.

HYPERELLIPTICAL NUDE DIAMOND TIP

Its optimized contact area is longer and narrower than the traditional
biradial (elliptical) tip-groove contact area.  This optimization results
in dramatic reduction of both harmonic distortion and intermodulation
distortion.

DYNAMIC STABILIZER

Viscous-damping functions like a shock absorber to resist sudden changes in
motion, enabling the tone arm to follow the irregularities of a warped
record surface.  Record warps can cause sudden and rapid changes in arm-to-
record distance that produce drastic increases and decreases in tracking
force and tracking angle.  The results can be signal wow, groove skipping,
cartridge bottoming, or even amplifier or speaker overload.  The Dynamic
Stabilizer remedies warp effects arm to the record surface.  The cartridge
achieves its full potential trackability despite warped records.

Conductive fibers neutralize static charges on the record surface and
conduct them to ground.  The fibers also sweep the record groove clean of
dust and dirt in front of the stylus tip.  And the entire Stabilizer
absorbs impact to prevent record or stylus damage if the arm is
accidentally dropped on a record.

SIDE-GUARD STYLUS PROTECTION SYSTEM

The SIDE-GUARD responds to accidental side thrusts on the stylus by
withdrawing the entire shank and tip safely into the stylus housing before
damage can occur.

P-MOUNT

This cartridge can be used as a P-Mount.
