True high fidelity sound recreation 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 mini-
aturized electric generator (thats really what it is) must carry the full burden of
translating the miles-long stereo record groove into usable electrical impulses
. . . and should do this without adding or subtracting from what is on the record-
ing. Knowing this, Shure quality standards are rigidly maintained at the highest
levels.

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

The trackability curve above dramatizes the differences in trackability between
the V-15 Type II Improved (shown at 3/4 gram) and the extraordinary Shure V-15
Type Ill (shown at 3/4 and 1 gram). The shaded area represents the recommended
theoretical limits for cutting recorded velocities. Peak recorded velocities are
shown up the left edge, frequency range is registered across the bottom. The
smoother the curve of the cartridge being tested and the greater its distance
above the shaded area, the greater its trackability.

The photomicrograph above left portrays an errant, hard-to-track castanet sound
in an otherwise conservatively modulated recording. The somewhat more heavily
modulated grooves shown above right are an exhilarating combination of flutes
and maracas with a low frequency rhythm complement from a recording cut at
sufficiently high velocity to deliver precise and definitive intonation, full dynamic
range, and optimum signal-to-noise ratio. Neither situation is a rarity, far from it.
They are the very essence of todays highest fidelity recordings. But when played
with an ordinary good quality cartridge, the stylus invariably loses contact with
these demanding grooves-the castanets sound raspy, while the flute and
maracas sound fuzzy, leaden, and torn apart. One of the most common, most
universally audible examples of mistracking occurs on vocal recordings when a
cartridge attempts to track sibilant sss and th sounds. Mistracking here pro-
duces clearly audible, intrusive sibilant distortion. Increasing tracking weight
to force the stylus to stay in the groove will literally shave off the groove walls.
Only High Trackability cartridges will consistently and effectively track all the
grooves in todays recordings at light, record-saving pressures . . . even with
cymbals, orchestral bells, and other difficult-to-track instruments. They will pre-
serve the fidelity and reduce distortion from all your records, old and new.

Shure cartridges
and the

ln addition to their many other individual features,
the Shure cartridges shown in this catalog offer the
audiophile a uniformity of manufacture and per-
formancethat is unique in high fidelity componentry.

We call it the U factor . . . U for uniformity. lt
assures you that not only does the Shure cartridge
you have conform precisely to its published specifi-
cations, but so does every other Shure cartridge
bearing the same model number!

Uniformity doesnt come easily. It takes infinite care
in production, and one of the most uncompromising,
most comprehensive quality control programs in
the high fidelity industry. The simple fact is that
every cartridge or stylus with the Shure name on it
either meets all of its specifications or is rejected.

Thus, a Shure V-15 Type III cartridge will provide
superlative performance no matter where it is pur-
chased-from Portland, Oregon to Portland, Maine;
from London to Rome; and from Tokyo to Paris to
Johannesburg.

And the original sound of any Shure cartridge can
be recreated exactly-no matter where the genuine
Shure replacement stylus is purchased.

The U factor. . . a part of every Shure cartridge and
replacement stylus.

SPECIAL NOTE: The Dynetic® stylus assembly used in Shure
cartridges is the most critical component. To maintain the
original performance standards of your cartridge, be certain
that any replacement stylus you buy bears the following
certification on the package:
