The
all-important
source of sound

True high fidelity sound re-creation begins at
the source of sound. Since the stylus is the
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, Shure 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 uniformity. 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 dont jeopardize your valuable
record collection by using imitation styli.

SPECIAL NOTE: The Dyneticf stylus assembly used in Shure car-

trid es is the most critical component. To maintain the original
ormance standards of your cartrid e, be certain that any re-

placement sytus you buy beds the to lowing certification on the

packa e:

about trockobility

Trackabiiity is the measure of a cartridges total performance,
High Trackability enables the styFus tip to fellow the hyper»
complex record groove up to and beyond the theoretical cutting
limits of todays modern recordings - not only at a select and
discrete frequency, but across the entire audible spectrum - at
lighttracking forces that are below both the threshold of
audibie 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 actuairy measured on
difficult-to track records. Although a cartridge with moderate
trackabitity will be able to track Oil the recorded velocities
encompassed within the theoretical cutting stylus limits,
substantially higher trackabllity is needed to track recorded
velocities actually found on todays discs. The Vl5 Type IV tracks
more of the hottest points at 0 .0w styrus force than any other
cartridge. The curve shown is fori gram tracking force. By
increasing the tracking force to H Mi grams, even more of these
points - virtual-y at: records produced thus far wil be tracked.

the record groove

The above left photomicrograph shows a record of musical
material cut at todays hotter " velocities after only one play with
a well known competitive cartridge at its rated tracking force.
This cartidge mistracked the record. Clearly, critical damage
resulted. Notice the deep gouge marks on the groove walls.

The above right photo shows the same groove [on an identical
record] played 50 times with a Shure High Trackability 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 mistrack can result in MORE damage than 7.5, 50 or even
TOO plays of a record! Record wear is a gradual but constant
phenomenon . . . like fire wear every 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.

TRACK/\BILITY is the single most meaningful yardstick by which to
measure cartridge performance. TTQACKABILJTV 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 TRACK/\BlLlTY - other performance factors

are irrelevant.
