SHURE-SME MOUNTING INSTRUCTIONS:
To mount the car-
tridge in the Shure-SME Precision Pickup Arm, Model 3009 and
3012, refer to the paragraphs on Cartridge Installation and Balanc-
ing in the instruction Manual supplled wlth the pickup am.
OPERATION
:
Recommended needle forces for optimum results
are listed under "Specifications." Forces greater than the indi-
cated "maximum" should not be used.
CONNECTIONS
4-LEAD STEREO CONNECTION:
Connect "hot" lead of right
channel to terminal
"R"
and shleld or ground lead of nght chan-
nel to terminal "RG." Connect "hot" lead of left channel to ter-
minal
"L"
and shield or ground lead of left channel .to "LG."
To prevent "ground loops" and hum, no common connection should
be used at
cartridge
terminals.
MONAURAL CONNECTION
:
For single channel reproduction of
Monaural or Stereo recordings, connect "hot" lead to both
"R"
and
"L"
terminals and connect ground or shield lead to both
ground terminals marked "RG" and "LG."
Suggestions for Cleaning Your Stylus
To clean, the stylus, use a camel's-hair brush (No. 2 size or
smaller) dlpped lightly in alcohol. The alcohol will remove any
sludge deposits which may have coated the stylus tip. The brush
bristles should be trimmed to a length no longer than
?4
inch.
Always
brush the stylus with a forward movement from the rear
(terminal end of the cartridge) to the front. Never brush or wipe
the stylus from front to back or side to side.
CAUTION:
Do not make solder
connections to cartridge termi-
nals. Make all solder connections
to terminal jacks provided before
slipping them over the terminals.

SPECIAL NOTE:
The Dynetic stylus assembly used in these car-
tridees is the most critical com~onent.To maintain the orininal
perfsrmance standards of your tartridge, be certain that any re-
placement stylus you buy bears the following certification on the

LABORATORY TEST FINDINGS:
(Note: The followin
st
lus
test findin s of the Shure N3D stylus are an example of t%e cyose
scrutiny ~%urepays to all imitation Shure Dynetic Styli.) Shure
laboratory tests show that the imitation stylus assemblies labeled
as replacements for the Shure Model N3D Stylus Assembly vary
drastically in important performance characteristics. For example,
the compliance varied from a 10.w of
0.9
to a high of 11.5, requirin
9.0 grams to track a record wlth a low compliance stylus, and
3
grams with a high compliance stylus. The high compliance stylus
retracted at
4
grams needle force, allowing the cartridge case to
drag on the record surface, thereby becoming inoperative. Re-
sponse at high frequency (relative to the lkc level) ranged from a
5.5db peak to a drop of 7.5db. Separation varied from "good"
(27db) to "poor" (16.5db), at
1
kc. These figures reveal that there
is very little consistency in performance characteristics of the
imitation Dynetic Styli.
In each of the categories shown above the results ranged from
good to poor. As a matter of fact, only 10% of the samples met the
Shure performance standards tor the Shure N3D Stereo Dynetic
Stylus. In addition to our test findings, our Service Department
records show that an increasing number of Dynetic Phono Car-
tridges are being returned because of poor performance-and our
examination ,has disclosed that most of these returned cartridges
are using im~tatlonDynetlc Styli.
CONCLUSION:
Obviously, if
any
imitation Dynetic Stylus is used,
we cannot guarantee that the performance of Shure Dynetic
cartridges will meet the published Shure
specifications.
Accept no
substitute.
Guarantee
The Stereo Dynetic Cartridges and Stereo Dynetic Styli are
guaranteed to be free from electrical and mechanical defects for
one year from the date of shipment from the factory, provided
all instructions are complied with fully. The Guarantee does not
cover stylus wear, nor does it cover damage to the stylus assem-
bly from abuse or mishandling.
