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-Γ (Gamma) Series

 The SR-Γ (Gamma) and SR-Γ pro New are improved model of the original Model SR-5N. It offers the proven life-like sound qualities and performance of SR-5N Earspeaker and feature a new cage grid frame constraction. Thanks to the world's thinnest diaphragm, fashioned out of a high-moleculer film 2.0 (1.5 for Pro) micron thick, the SR-Γand SR-Γ Pro New achieve superb transient and uncomparable mid and high transparency.
  The new cage grid design gives full play to all the performance potential of the earspeakers and contributes to the light-weight, comfortable fit that will definitly enhance your listening pleasure. Stax SR-Γ professional has been improved incorporating newly designed ear pad. With this ear-pad, SR-Γ Pro's low frequency reproduction ability has been tremendously made rich.
 The standard SR-Γ earspeaker first appeared in 1985. its transducing diaphragm is two microns-thick, providing superior transient attack. It is supplied with the SRD-6sb energizing adaptor, which attaches to the output of a power amplifier. This adaptor is self-biasing (deriving its power from the audio signal itself); no AC power is required, thus granting the user greater flexibility regarding its placement.
Stax SR-Γ Professional specifically designed for the American market, the SR-Gamma earspeaker models occupy a price plateau below that of the Lambda products; since the Gammas utilize the same advanced technology and claim many of the same sonic attributes,, they constitute a genuine bargain. Their open-type oval enclosures prsent a clear, balanced sound field uncolored by cavity resonances or reflections.  The Gamma Professional contains the 1,5 micron-thick diaphragm and increased electrode gap and bias voltage found in the SR-lambda pro. It comes with the SRD-7 Professional energizing adaptor.
