SRS-3030

Classic System II

(SR-303 Classic+ SRM-313)

The SR series
Earspeaker is the fruit of
the most up-to-date tech­nology and 40-year's ex­perience of STAX that first
developed and manufac­tured the electrostatic
headphone, that is the
first "Earspeaker", in the
world.
Differently from ordinary
headphones, this
Earspeaker is equipped
with neither magnet nor
coil, but utilizes electro­static force to generate
sophisticated sound.
In detail, the core of an
Earspeaker is composed
of a thin diaphragm
(oscillatory film) to which
a DC voltage of 580V is
supplied.
When audio signal is sup­plied to the electrodes,
electrostatic force gener­ates and drives the dia­phragm to reproduce the
sound.
Thanks to this operation
principle, the Earspeaker
reproduces sound very
naturally and delicately in
all nuances.

FEATURES

SR-303 Classic Headphone
Diaphragm material reduced to a thickness of Only 1.35
micron

Featuring the same element material as the SR-404 Signature, the Stax
SR-303 Classic is a startling innovation in a more affordable earspeaker
package.
The sound is both refined yet powerful and the unit comes complete with
a low capacitance standard PC-OCC cable to allow the Stax SR-303
Classic earspeaker to attain their full sonic potential.

SRM-313 Driver Unit
Low Impedance Output Stage

The SRM-313 Driver Unit features a completely redesigned output stage
that utilizes an up-to-the-minute emitter follower in the output circuitry.
This along with a further improvement in the power supply circuitry re­sults in life like sound rich in scale and dynamics.
