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.
<Refer to SRM-313 brochure for further details.>
Specifications and design are subject to change without notice for
improvements.
