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.

Sansui SS-2

 Stereo headphone
Complete engineering on both electronic and human levels brings a new kind of sound purity and comfort to the stereo enthusiast in the form of Sansui's Stereo Headphone set, Model SS-2.
Electronically, the SS-2 utilizes specially developed cone-paper with very high radiation characteristics to overcome a problem that has plagued stereo manufactures for years - faithful reproduction in the low-frequency ranges.  The moving coil type SS-2 shows excellent transient stability throughout the entire range of 20-18,000 Hz, with exeptional impedance and L/R balance characteristics as well as high damping factor.

Outstanding Bass Reproduction 
The cultivation of a very high-radiation cone-paper enables low-frequency reproduction all the way down to 20 Hz, a figure almost beyond the reproduction capability of a 12-inch woofer. Distortion is less than 1% at 1 mW input. 

Flat Characteristics 
The high-moving coil with its excellent transient stability, and special cone-paper with its superior vibration characteristics (70 mm in diameter) combine to completely cover the wide range of frequencies from 20 Hz to 18,000 Hz. The impedance characteristic is also excellent, allowing powerful sound reproduction with a high damping factor. 
 Right and Left Channel Balance 
The output sound pressure level is rated at lower than 1 dB for perfectly balanced stereo reproduction from both Right and Left channels. Unlike listening via speaker systems, headphone listening assures an optimum stereo effect, since Right and Left channel sounds never have the chance the interfere with each other in the air. 

Ear Pads Designed for Comfort 
The ear pad for model SS-2 are made of softly finished Vinyl-Chloride, leather-like in appearance. They have been doubly finished so that ambient heat never becomes a comfort-impairing factor. They can be worn over an extended period of time in complete comfort. 

Functional and Attractive 
The head band is completely adjustable for individual head and ear positioning.
The SS-2 is available in black and white two-tone design. 

The SS-2 is a highly-sensitive headphone set. Its sound output is extremely high even at an input as low as one-thousandth of a watt. If the amplifier power is beyond the Maximu Rated Power Input, there is a possibility of damage. Therefore, in connecting this set directly to higher-powered amplifier the volume of the amplifier should always be reduced.
