DUAL MOVING MicroCoiI PHONOGRAPH CARTRIDGE

INTRODUCTION

Your new Audio-Technica cartridge is a significant achievement in
precision manufacturing. Completely hand assembled, tolerances are
held to just thousandths of an inch. Audio-Technica has specialized
in precision transducers for over a decade, building an international
reputation for accuracy and uniformity. The Dual Moving MicroCoil
Series of phono cartridges is the latest refinement of this tradition of
craftsmanship and advanced design.

PRELIMINARY INSTALLATION

Before mounting the cartridge, the stylus assembly should be re-
moved for safekeeping. Hold the cartridge in one hand, grasp the
plastic stylus housing with thumb and fore-
finger, and pull directly away from the car-
tridge. The stylus assembly comes away at
a slight rearward angle, as indicated by the
arrow in Figure 1. Place the stylus assem-
bly out of harms way until installation is "
completed.

Using the mounting hardware supplied
either with the cartridge or with the turn-
table, mount the cartridge according to the
recommendations of the turntable manufac-
turer. Hardware should be tightened down slightly, so that the car-
tridge position does not change, but avoid excessive force which
may strip plastic threads or warp delicate parts out of position. After
the cartridge is mounted, replace the stylus assembly briefly. The
stylus assembly should click into place when fully seated on the
cartridge. Check visually to make sure that there is no mechanical
interference with mounting hardware. Again remove the stylus as-
sembly for safekeeping until electrical connections are completed.

ELECTRICAL CONNECTIONS

Four terminals are provided at the rear of the cartridge-an output
and ground connection for each stereo channel. For proper perform-
ance of your system, the correct wiring must be carried through to

the internal cartridge connections.

For monaural Operation, the left and right signal terminals should
be connected to the monaural signal lead, and the left and right
ground terminals should be connected to the ground lead. With
these connections, vertical output from the cartridge is cancelled,
thus reducing record noise which is primarily in the vertical direction.

FINAL INSTALLATION

Re-install stylus assembly. Following the procedure recommended
by the turntable or tone arm manufacturer, carefully set tracking
force within the range shown for your cartridge in the Specifications
table. This is a critical adjustment, since tracking force higher or
lower than recommended will result in increased distortion and
decreased record life. Similarly, the tone arms adjustments, if any,
for stylus overhang and anti-skating must be set prOperly if maximum
benefit is to be obtained from your cartridge.

After all tone-arm adjustments have been made, the stylus may
remain installed in the cartridge. However, the plastic stylus guard
should be used to protect against accidental damage, as at any
time when the turntable is not in use.

CONNECTION TO SYSTEM

Because of the relatively low output voltage of the AT30E Dual
Moving MicroCoil cartridge, compared to moving magnet designs,
normal magnetic phono inputs will not provide sufficient ampli-
fication for satisfactory reproduction. Some amplifiers and receivers
have MC phono inputs which are appropriate for the AT30E.

For best performance, however, use of the AT630 Transformer is
recommended with the AT30E and normal magnetic phono inputs.
Normally, the AT630 is located near the electronics input, and the
output cables from the tone arm are fed directly to it. Both input and
output connections of the AT630 are coded with channel identifica-
tions (left channel input and output connectors with L and right
channel connectors with R and also color-coded red). The AT630
should be kept away from strong magnetic fields (transformers and
motors). lf hum is noted, relocating or reorienting the transformer
