_ The
all-important
source of sound

True high fidelity sound re-creation begins at
the source of sound. Since the stylus isthe
only point of contact between the record
and phonograph system, the sound can be
no better than the cartridge, This
breathtakingly precise miniaturized electric
generator [thats really what it is) must carry
the full burden of translating the stereo
record groove into usable electrical
impulses. . . and should do this without
adding or subtracting from what is on the
recording. Knowing this, Share quality
standards are rigidly maintained at the
highest levels.

in addition to its many other features, a Shure
stylus offers a uniformity of performance that
is singular among high fidelity components
We call it the U factor. .,U for miformity. it
assures you that your Shure cartridge and
stylus not only conform precisely to their
published specifications, but every other
Shure cartridge and stylus with the same
model number does as well!

This uniformity doesnt come easily. it
requires infinite care in production along
with a stringent. comprehensive quality
control program,

As a result, when the stylus eventually wears
out, the original sound performance of your
cartridge can be restored no matter where
you buy your genuine Shure replacement
stylus - so don tjeopardize your valuable
record collection by using imitation styll.

about lrockobility

Trackability is the measure of a cartridges total performance,
High Trackability enables the stylus tip to follow the hyper~
complex record groove up to and beyond the theoretical cutting
limits at todays modern recordings - not only at a select and
discrete frequency, but across the entire audiblespectrum - at
light tracking forces that are below both the threshold of
audible record wear and excessive stylus tip wear

In the graph above, the shaded area represents recommended
theoretical limits of record cutting velocities. The scattered points
are the hottest recorded velocities actually measured on
difficult-to-trdck records, Although a cartridge with moderate
trackability will be able to track all the recorded velocities
encompassed within the theoretical cutting stylus limits,
substantially higher trackability is needed to track recorded
velocities actually found on todays discs, The V15 Type lV tracks
more at the hottest points at a low stylus force than any other
cartridge, The curve shown is tori gram tracking force. By
increasing the tracking force to 1-1/4 grams, even more of these
points - virtually all records produced thus for - will be tracked.

a wellrknown competitive cartridge at its rated tracking force.

The above right photo shows the some groove [on an identical
record] played 50 times with a Shure High Trockability Cartridge,
at a record- and stylus-saving force of only one gram. The stylus
never lost contact with the groove, and never damaged

the record.

A single mislrack can result in MORE damage than 25, 50 or even
100 plays of a record! Record wear is a gradual but constant.
phenomenon . . ,like tire wearevery time you drive, But a mistrack
is like a blowout, Once your cartridge mistracks a record
passage, the damage has been done and that passage will
never sound the same,

TRACKABILITV is the single most meaningful yardstick by which to
measure cartridge performance. TRACKABlLlTY encompasses
the effects of virtually all the design factors (compliance,
effective mass, resonances, damping, etc] that ultimately
determine cartridge performance. And unless the stylus
maintains intimate contact with the record groove walls - the
essence of TRACKA BlLlTY - other performance factors

are irrelevant.
