BIFOLD-PARAFLUX Coil Core
Interlocking
The cartridge body of the ML140HE contains
an abundance of new functional electrical
featuresfor highoutput with maximumfidelity.
a The BIFOLD-PARAFLUX coil-core has
prealigned two-layer folded pole pieces
with parallel flux laminations to provide
greater efficiency of energy transfer and
maximumchannel separation. The result is
superb stereo imaging and depth.
w The architecture of the internal frame in-
terlocks to produce a completely rigid,
nonresonant substructure. The cartridge
body will never wear out or cause deteriora-
tion of the sound.
a The true humbucking coil configuration
results in maximum hum cancellation.
a The noncorroding gold-plated terminal pins
ensure continuity of the signal path.

The Dynamic Stabilizer has been newly design-
ed to maintain the traditionally distinguished
Shure effectiveness in overcoming real-world
warp, static, and dust obstructions to record-
playing accuracy.
w The Stabilizer's viscous-damping reduces
warp and tone arm resonance effects to in-
significance. The newly designed miniature
pivot system acts like a shock absorber to
prevent groove skipping, mistracking, and
distortion caused by record warps.

ML140HE
The electrically conductive Stabilizer fibers
remove static charges from the record sur-
face and conduct them to ground to
eliminate static charge noise and minimize
the attraction of dust tothe record surface.

More than 10,000 tiny fibers in each
Stabilizer reach down into the groove to
sweep away interfering and abrasive dust
and grit. Records stay cleaner and noise
free longer.
Functioning like a shock absorber, the
Stabilizer protects the stylus from damage
if it isaccidentally dropped on the record.
The unique Shure
SIDE-GUARD protects the
stylus from accidental damage caused by im-
pacts from the side, such as when the tone
arm slides across the record.

The elements of the stylus have been
meticulously optimized for low effective mass,
continuity of groove contact, and accurate
duplication of intricate groove modulations.
The result is a cartridge with excellent sound
clarity that enhances the enjoyment of listen-
ing to records. Three features of the design
provide this exceptional performance.
m The ultra-thin wall beryllium shank com-
bines an ideal configuration with an ideal
material. Beryllium is extremely light, yet
highly rigid. Shure has developed a unique
fabrication method, called MICRO-
WALLIBeTM,that forms the shank into a
thin-wall tube of 13p-thick
(.0005 inches)
beryllium. This yields the highest ratio of
stiffness to density of various attainable
shank materials and configurations. We
call this ratio the Shank Performance Ratio
(SPR); higher numbers mean improved per-
formance, especially in high-frequency
trackability. To the listener it means that
the onset of complex difficult-to-play
sounds, such as trumpets, pianos, female
vocalists, and full orchestras, will sound
truer and will be cleanly reproduced.

Below are shown various possible beryllium
shank structures, and the SPR of each.

w The hyperelliptical tip geometry has an op-

FREQUENCY RESPONSE, TRACKABILITY,
AND HIGH FIDELITY
Performance is the ultimate test of success
for any cartridge design.
Frequency response
and trackability specifications are two of the
most important indicators of successful high-
fidelity performance.
Frequency response demonstrates the ac-
curacy of reproduction of tones across the en-
tire audible spectrum.
A flat frequency
response displays a cartridge's ability to
reproduce
all sounds without emphasis or at-
tenuation. The tonal balance of low, mid, and
high pitchedsounds are reproduced exactly as
they were recorded.
Trackability measures the ability of a stylus,
at a given tracking force, to maintain contact
with both groove walls while negotiating the
tortuouspeaks, valleys, andhairpinturns of to-
day's heavily modulated record groove.
A car-
tridge must allow the stylus tip to stay in firm
contact with the groove walls to produce clear,
clean, undistorted sound, and to prevent
record groove damage that permanently alters
and distorts the sound.

An authentic high-fidelity cartridge MUST
have a
flat frequency response and high
trackability at a very low tracking force. THE
ML140HE MEETS THESE CRITERIA. Its fre-
quency response isessentially flat from 20 Hz
to 22,000 Hz. At a tracking force of 1 gram, it
typically tracks signals of the following
velocities (in cmlsec peak recorded velocity):
400 Hz
- 29 cmlsec
1,000 Hz
- 42 cmlsec
5,000 Hz
- 60 cmlsec
10,000 Hz
- 50 cmlsec
The final test of performance is operation
under less than ideal real-world conditions.
The Dynamic Stabilizer prevents interference
from record warp, arm resonance, shock, and
dirt and dust; the SIDE-GUARD protects
against stylus damage. The ML140HE per-
forms flawlessly-it lets you listen to the
music!

INSTALLING THE CARTRIDGE (see page 20)
1. Remove the stylus.
2. Make electricalconnections: right channel (R),red
lead; right ground (RG),green lead; left channel (L),
white lead; left ground (LG), blue lead.
3. Mount the cartridge:
A. In a headshell with unthreaded holes or slots.
0. Ina headshell with threaded mounting holes.
4. Cartridge Leveling: Check that the front and side
of the Alignment Stylus is parallel to a record on
the turntable. If necessary, insert spacers or a
shim, or rotate the headshell.
5. Overhang Alignment: Place the Overhang Gauge
over the turntable spindle, and adjust the position
of the cartridge in the headshell until the Align-
ment Stylus is parallel to the Gauge markings.
6. Tracking Force: This cartridge is designed for an
optimum tracking force of 1.0 gram (1.25 grams
maximum). The viscous-damped Dynamic
Stabilizer exerts a force on the record of 0.5 grams
that must also be accommodated in the total tone
arm tracking force setting. Therefore, use the
following settings.
To obtain this force Set the arm tracking
at the stylus tip force adjustment to
Optimum 1.0 gram 1.5 grams
Maximum 1.25 grams 1.75 grams
To use an external gauge such as the Shure SFG-2
Stylus Force Gauge to set the tracking force, lock
the Dynamic Stabilizer "up", and set the tracking

force as shown in the second column. When the
Stabilizer rides on the record with the cartridge in
use, the extra
0.5 grams will be offset by the
Stabilizer and WILL NOT APPEAR AT THE
STYLUS TIP. The tip force will bethat shown inthe
first column.
If for any reason the cartridge is used with the
Stabilizer "up", the tracking force should beset as
recommended for the tip:
1.0 gram Optimum, 1.25
grams Maximum.
7. Skating Compensation: Set the mechanism as
recommended by the tone arm manufacturer. Use
a skating compensation corresponding to the
total tone arm tracking force setting.
8. Operation: Carefully place the Dynamic Stabilizer
in the "operating" position so that it floats below
the cartridge. The cartridge is now ready to use.
9. Cleaning:
To clean the Stabilizer, use
no fluids. Use the
brush supplied with the cartridge.
To clean the stylus, use the brushwith alcohol or
an alcohol-distilled water solution or the Shure
SK-I Stylus Cleaning Kit.
Brush only from back to front as shown. Commer-
cial cleaning solutions may cause stylus damage.
