OMNl-DYNAMIC STEREO HEADPHONES

Sansui gives stereo music listeners
the rich bass of dynamic acoustic
transducers as well as the wide frequency
range and brilliant musical reproduction
qualities of the electrostatic types in these
allenew. smartly designed $87100 stereo
headphones.

Omni" means that the diaphragms
inside the comfortably fitting earpieces
each distribute a uniform driving force

over its entire flat surface. avoiding

split vibrations. The low mass of each
diaphragm also means less total harmonic
distortion and less phase distortion-the
same advantages you have with electro-
static drivers, But since the 88-100 design
is essentially dynamic. no electrostatic
adaptor or special amplifier is required.
and you enjoy a natural yet powerful bass
reproduction as well.

With the Sansui Omni-Dynamic SS-iOO.
frequency response is flat over the entire
musical spectrum from superlows to
ultrahighs. Harmonic distortion is minimal.
impedance is flat with no trace of peaks
or dips. and your amplifier or receiver is
shown off at its best without overstraining.

Hear the new-concept 88-100 sound
and judge for yourself. From Sansui.
where it's all hi-fi.

COMBINING THE BEST OF DYNAMIC AND
ELECTROSTATIC PERFORMANCE

OMNl-DYNAMIC PRINCIPLE

These handsome, Sansuiexclusive head-
phones employ an omni-dynamic transducer
(diaphragm) in each earpiece. The units are
made of polyester film, stretched to a uniform
tautness and contained between two anisotropic
magnet plates (Fig. 1). On the diaphragm film
is etched a voice coul pattern (Fig. 2). And each
of the magnet plates has a field (Fig. 3) which.
when activated by the plus and minus pulsa-
tions of the musmal input signal. moves the
diaphragm to and fro based on Fleming's
left-hand rule as applies to current flow in coils.

DRIVER CONSTRUCTION

OmnI-Dynamlc Driver

As they are very thin and low in mass. the
diaphragms offer excellent transient charac-
teristics over a wider lrequency range than can
those shaped as cones or domes. This means
you have a flat response from the superlows
to ultrahighs with any musical input signal.
Omni-dynamic drive means. too. that all
secnons of the diaphragm surfaces move in
linear piston motion. without split vibrations.
thus reducing harmonic distortion and
extending dynamic range.
Powerful Magnets

The anisotropic magnet plates in the 85-100
each have high magnetic density to afford the
headphones the very high sensitivity ietficiency)
of 94dB/mw.
Optimum Amplifier Load

Since the impedance of these headphones is
literally constant at all frequenCIes. your
amplifier or receiver is asked only to deliver
an optimum load. meaning that you are assured
ol the best sound quality from your unit.
No-Adaptor Design

To drive the 88-100 simply plug in the
provided jack at the headphone outlet on your
amplifier or receiver. No AC power booster or
other adaptor is required.

IGUE E DESIG

Comfortable Wearing

Eight neoprene supports separate the ear-
piece from the headband assembly. increasing
wearing comfort. The earpads are soft and
slim-sxlhouetted for further comfort. and the
recess inside each is shaped to optimize air
compliance tor better musical reproduction.
even into the very high frequency range.
Clear Channel Identification

Youll never coniuse front and back or lelt
and right: two clearly-marked arrows point to
the front of the headset. and only the left

earpiece has a cable cord. both for channel
identification and wearing comfort.
Slim Design Throughout

Since these Sansui-exclusive Omni-Dynamic
drivers themselves are flat. thin and compact.
the earpieces have been designed to present
a slim silhouette. Other design elements take
up this low profile motif to result in a modern
and quite comfortable stereo headphone set
you'll enioy for long years of hard use.
