AT450E/OCC Dual Magnet Stereo Phono Cartridge

INSTRUCTION MANUAL

This cartridge features Audio-

31-'-

C!

Technica's patented PRACTI-
CALLY IDENTlCAL TO THE CUT-
TER HEAD" performance. Dual
Magnet design. a Paratoroidal gen-

/ erator coil circuit. a .4 x .7 mil ellipti-
cal stylus, plus other advanced
designs for top performance. In order

to assure that the AT450E performs up to its design specifications.
we ask that you thoroughly read these instructions prior to using the
cartridge. The AT450E/OCC uses a new type of wire called PCOCC
(Pure Copper by Ohno Continuous Casting process) in the con-

struction of its coil and lead wires

Preliminary Installation

Remove the stylus assembly for
safekeeping. With the clear sty-
lus guard down to protect the
stylus. remove the stylus assem-
bly by rotating it down and away
from the cartridge body (Figure
1). Place the stylus assembly
safely out of harm's way. Mount

Figure 1

the cartridge body to the tone
arm head shell. Use the mount-
ing hardware supplied eitherwith
the cartridge or with the turn-
table. and tighten until just snug.
Replace the stylus assembly
briefly to check for mechanical
interference with mounting hard-
ware. Hook the back of the sty-
lus assembly to the bottom of
the cartridge, then rotate up. The
stylus assembly should click into
place. Then remove the stylus
assembly again for safekeep-

ing.

Electrical Connections

The four terminals at the rear of
the cartridge are color-coded to
match standard wiring in stereo
tone arms (Figure 2). Connect
these using the slip-on lugs
provided on the head shell wires.

NEVER SOLDER TO CAR-
TRIDGE TERMINALS! Heat
applied to the terminals will
damage the internal cartridge
wiring. For monaural operation,
the Left and Right signal termi-
nals should be connected to the
monaural signal lead. and the
Left and Right ground terminals

should be connected to the
ground lead.

Connection to System

Run two shielded audio cables
from the cartridge/tone arm
connections on the turntable to
the moving-magnet phono in-
puts on the amplifier or receiver.
Observe Left and Right channel
markings. A separate ground
wire usually comes attached to
the turntable, and should be
connected to the ground screw
found on the back panel of most
amplifiers.

Final Adjustment

Reinstall the stylus assembly.
Following the procedure given
in the turntable/tone arm instruc-
tions. carerully set the tracking
forcetoapproximatelythemiddle
of the range shown for your tone
arm in the specifications table. A
tracking force outside the given
range can result in increased
distortion and excessive record
and stylus wear. Other tone arm
adjustments, such as stylus
overhang and anti-skating,
should be set according to
manufacture's instructions to
obtain the best performance. For
safety. keep the stylus guard
down whenever the turntable is
not in use.

Operating Suggestions

The low tracking force and high
compliance of Audio-Technica
cartridges provide the highest
level of performance available,
but also make them susceptible
to damage if handled improp-
erly. Most stylus damage is
caused by rough treatrnentwhile
the tone arm is being operated
by hand. A finger should always
be placed under the tone arm
finger lift, neveroverit. A damped
cueing device which lowers the
tone arm gently to the record is
found on many record players
and should be used regularly for
greatest protection of the stylus
and records. Distorted or unbal-
anced sound from the two phono
channels often can be traced to
wires interchanged or touching
at the cartridge terminals. A

reduction in output or muffled
sound may result if the stylus
assembly is notfully seated. Hum
from the phonograph input usu-
ally an be traced to a bad audio
cable or absence of the sepa-
rate ground wire from turntable
to amplifier.

Replacement Styli

Audio-Technica grain-oriented
diamond styli are carefully se-
lected and polished for minimum
wear to themselves and to your
records. However. after an ex-

tbnded period of play. even the
finest diamond stylus becomes
worn. Forthis reason. itis bestto
have the stylus inspected annu-
ally. or whenever it appears that
wear or damage may be a prob-
lem. The dealer from whom you
purchased this cartridge is
equipped and competent to in-
spect and evaluate the stylus.
and can supply genuine Audio-
Technica replacement styli. Only
genuine styli with the registered
circle monogram will provide the
same level of performance.
