What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

STAX SR-Λ (Lambda) Signature

 Above fifthy five years ago (1959), Stax became the first company in the world to develop and manufacture Electrostatic Headphone, "Earspeaker". Today, our experience is making a dramatic difference  that you can enjoy. For example, Daimler-Benz was so taken with "Stax technology" that they requested  a special earspeaker to test the acoustic environment in their limousines. This earspeaker became well-known as the SR-Λ Professional. Now, the SR-Λ Signature is the successor to the SR-Λ Professional. It is constructed of select materials and is hand assembled to meet the superlative standard of Mr. Naotake Hayashi, the president and founder of Stax.
Stax is proud to have created a new reference standard for earspeakers that obtains an even higher level of performance than the SR-Λ Professional. The Signature series SR-Λ uses a transducing diaphragm made of high-polymer that is only "one" micron thick. The signal cord is made of PC-OCC cable that is specialy cast from pure copper to preserve phase integrity through large linear crystalline structure.
 The SR-Λ Signature  is designed to operate at 580 V D.C. bias.it can be used with any Stax professional adaptor or direct drive amplifier. The SRD-7/Mk2 and the SRD-7sb/Mk2 are adaptors that enable the SR-Λ Signature and normal-bias earspeakers to work in conjunction with any high quality amplifier or receiver. The SRD-7/Professional is an adapter that enables two SR-Λ Signature  earspeaker (or two other pro-bias earspeakers) simultaneously to work in conjunction with a high quality amplifier or receiver. The SRD-X/Pro and the SRD-P are portable adaptors.  They allow the use of the SR-Λ Signature  in remote locations. The SRM-1/Mk2 Pro is a Class-A DC direct drive amplifier for any Stax earspeaker. The SRM-T1 is a Hybrid FET/vacum tube direct drive amplifier that is Specifically designed to highlight the SR-Λ Signature . It also will drive any Stax earspeakers.
