The Lambda
Nova Series were designed for the person who loves the sound of the recent
SR-Lambda Series but needs more modern sofisticated design. We put new shaped
head-spring together with new sound units. As a result, the frequency responce
was flattened and the wear confort was refined. The Lambda Nova Series carry
the superiority of the former SR-Lambda Series and further more add special
merit of new sound unit and head spring.
The
Lambda-Nova Series earspeaker is the fruit of the most up-to-date technology
and many-years of 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 580 V is supplied. When audio signal is supplied
to the electrodes, an electrostatic force is generated that drives the
diaphragm to reproduce the sound. Thanks to this operation principle, the
earspeaker reproduces sound very naturally and delicately in all nuances.
Features
The
Lambda-Nova Series earspeakers are advanced products of the SR-Λ series that has continuously been improved for
more than 15-years.
For
upgrading the electrostatic transducer, Stax improved not only the processing
precision of the thin diaphragm that has
had an established reputation but also the structure of the electrodes to
receive the audio signal. This, with the first rate technology cultivated
through the manufacturing experience of the SR-Ω series. As a result, Stax
offers this earspeaker equipped with high quality transducers that are superior
to others in sound clarity and excellent reproduction in detail at all levels.
Most
earspeakers made by Stax are designed to operate with the pro bias voltage (580
V/DC). The lambda-Nova series earspeakers also work with the pro bias voltage,
however, Stax's old type earspeakers such as the model SR-1 that was put on the
market in 1960 for the first time were designed to operate with the Normal bias
voltage (230 V/DC). These two types of earspeakers can be discriminated from
each other by the number of pins on the connector cord plug. Namely, earspeakers whose connector plug has
6-pins are designed to use with the Normal bias voltage, while earspeakers
whose connector plug has 5-pins are designed to use with the pro bias
voltage.needless to say, the 5-pin connector of the Lambda-Nova series earspeakers
should be plugged into a connector jack that has 5 pinholes and is usually
identified with the indication of "Pro Only". If the lambda-Nova
earspeakers is connected to a 6-pinhole jack for Normal bias, the result will
be low volume and soft sound.
