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.

Wadia 7 Transport

If the essence of music is art, then th eessence of music reproduction is technique. And the quintessence of that technique is Wadia.
As we continue to make pioneering advances in digital reproduction, by applying advanced computer technology and patented programming to leading-edge signal decoding, we place increasingly greater demandads on th eelement of digital technology first in the reproduction chain; the transport.
For, while the New Generation of Wadia Decoding Computers has been engineered to achieve faithful reproduction of the very life of recorded music, the broad symphony of instrumental and vocal nuance, the aural ambience of soundspace, the audibly influential presence of the artists themselves, reproduction comes to naught lest the recorded signal is sent, intact, to these brilliant instruments of sonic  reproduction.

Enter the new generation of Wadia transports - designed, foremost, to ensure absolute mastery of signal recovery in the time domain; the genesis of optimum reproduction.
Wadia's proprietary clocking technology initiates digital timing accuracy at the LSI chip, setting the standard for accurate time-base relationships throughout the chain of digital reproduction equipment.
To isolate signal topology from power-supply generated noise, the Wadia 7 Transport has been engineered with a completely redesigned power supply, housed in its own substantial chassis. A state-of-the-art regulator stage ensures constant voltage sophisticated line filtering delivers a pure AC line feed to two toroidal transformers - the very best of current manufacture as is every component in the Wadia 7.
Enclosure design, too, is an essential element of distortion control and, as a result in a loss of information  which cannot be recreated by improvements later in the system.

Wadia's exclusive rounded-corner design detunes the enclosure from resonant frequencies which would have a negative impact of critical clock and program signals.
As the foundation for fautless signal recovery, the chassis of the Wadia 7, constructed of massive body plates, provides a profoundly stable platform for that most critical of all transport components, the spinning mechanism itself.
To expect near- perfect accuracy from heavy-handed servo-feedback corrections would seem folly. Thus, at the heart of the Wadia 7 Transport is the critically acclaimed P-2S spinning mechanism - an acknow ledged industry standard, utilized outside  the manufacturer's realm only within the Wadia 7.
Its full-size die-cast zinc/bronze disc turntable and stabilizer clamp keeps disc and laser pickup in their precise relative positions. With this dimensional stability and interial damping, servo corrections need only deal with tracking the variable disc rotation speed.
Combine full-disc clamping with a floating suspension system, sophisticated resonance damping design and the use of non-resonant metals - not plastic - throughout its understructure, and the result is a mechanical treatment which has risen to worldwide critical acclaim..

Function selection of the Wadia 7 is equally sophisticated. Sculpteed from a solid block of aluminum, the full-functions remote controller promises a lifetime of faultless service, reducing control intrusions into both cosmetics and mechanical integrity.
It is also your fully remote acces to the Wadia 7's matchless companion in unrivaled digital reproduction, the Wadia 9 Decoding Computer.
Truly, the Wadia 7 Transport brings unerring digital transport to reality, presenting, through Wadia's pioneering use of the Glass Fiber Optical Transmission System, the world's most accurate digital output, and offering for  your audition the essence of the art of music, through the twenty-first centry technique that is Wadia.
The Wadia 7 Transport  feature a complete array of output choices. Un mistakably, our prime choice is Glass Fiber Optics. To maintain compatibility between Wadia transports and all possible subsequent system components, we have included a plastic optics output, a Coax output via BNC, and an output in the AES/EBU  connection system.
Additional user-selected options are adjusted from the real panel of the wadia 7 Transport. Separate adjustments can be made for disc drawer insertion speed and ejection speed, and for display intensity.
