The creation ofthe
force in innovative engineering. The challenge was to
design a cartridge that would transcend all existing
cartridges in musical transparency, technical excellence,
and uniformity. The unprecedented research and design
disciplines that were brought to bear on this challenge over
aperiod of severalyean have resulted
pickup system that exceeds previous
by a
significant degree - not merely in one parameter, but
in totality. In fact, this pickup system has prevailed
simultaneously over several extremely
re-creation problems which, until now, have defied
practical solutions. Most of all, this is an eminently musical
cartridge which is a delight to the critical ear, regardless of
programmaterial, or the rigorous demands of today's most
technically advanced recordings.

The

Type N is a Stabilized, Static-free, Super-Trackability cartridge-stylus
system. The next few pages will explain the following advantages of the
SUPER TRACK
Demonstrably improved trackability
across the entire audible spectrum
especially in the critical mid- and
high-frequency areas.
Dynamically stabilized tracking configuration dramatically reduces

problems, such as fluctuating tracking
force, varying tracking angle and wow.
