AT30E
Stereo Phono Cartridge with Vector-Aligned Dual Moving MicroCoils and
user-replaceable Stylus.
A
top-quality moving coil cartridge exhibits remarkable sonic clarity and
transparency. This performance can be attributed to the very low mass, and low
inductance of the tiny coils used to sense the stylus motion. But until now,
moving coil cartridge popularity has been limited by three major problems which
seemed almost inherent to moving coil designs.
1)It
seemed impossible to make a user-replaceable stylus assembly without
compromising performance.
2)Most
moving coil cartridges exhibited relatively low tracking ability due to rather
stiff cantilever mounting system.
3)Outputof
the cartridge was below the level needed for commonly available amplifier
inputs.
Introducing
the new Audio technica AT30E and the end to all three problems. Our design
approach is simple and direct. Rather than localethe coils in the cartridge
body, they are integral with the stylus assembly. If the stylus becomes worn or
damaged, the entire moving system, coils and all, is simply unplugged and
replaced, just like a moving magnet cartridge. Large, gold-plated connectors
insure loss-free connections so vital at the low voltages generated by a good
moving coil cartridge. The result is easy field replacement with no penalty in
terms of performance.
Careful
research indicated that good tracking and moving coil design were indeed
compatible. By controlling, effective mass and utilizing a radial damping
system similar to our famed Dual Magnet cartridge, we have achieved excellent
tracking ability throught the audio range. Compliance is individually
controlled during manufacture of each assembly to optimize performance. This
extra step, impossible with most other designs, coupled with our unique radial
damping ring, insures excellent tracking of the high-energy modulation found in
many of the top-quality recording now available.
Each coil
is located in the ideal geometric relationship to reproduce "its"
side of the record groove. This Vector_Aligned design assures excellent stereo
separation, minimum moving mass, and the highest possible efficiency. It's
design concept which is exclusive to Audio-Technica, and is a major contributor
to the outstanding performance of the AT30E.
The AT30E
output is similar to many other fine moving coil cartridges. But an increasing
number of amplifiers and receivers are featuring built-in
"pre-preamplifiers" or "head amplifier" to accommodate
moving coil cartridges directly. Thus the new systems buyer can make a
cartridge choice based on sonic characteristics rather than on input
compatibility. In addition, Audio-Technica offers the Model AT630 Transformer
for matching to conventional amplifier inputs.
