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 G-6000

Time and a bit of genius make the difference. It wasn't easy to create the world's finest DC receiver. It look Time. A great deal of it. For research. For development. For testing. And it also a bit of genius - kind of genius that Sansui engineers are world famous for. But we at Sansui were determined. And we Succeeded. So now there is a patent pending on Sansui's unique new DC amplifier circuitry.

The Sansui G-6000 DC receiver, like Sansui's entire G-line of DC receivers, incorporates this unique technology it delivers music reproduction so superb you will actually hear the difference. With Sansui's DC amplifier circuity  you get better low frequency response. It extends all the way down to zero Hz (DC), from main-in. That's one reason it's called a DC receiver. With Sansui's DC amplifier circuitry you get better high frequency response. It goes all the way up to 200,000 Hz, from main-in. Just try to find another receiver with frequency response this wide. 
With Sansui's DC amplifier circuitry you also get fuller and faster response to musical transients. This is measured in slew rate and rise time. And the slew rate and rise time figures of the Sansui G-6000 are far better than those of any competitive models. And with Sansui's DC amplifier circuitry there is virtually no distortion. While eliminating the capacitors, we've solved the time delay problem that causes transient intermodulation distortion (TIM). And total harmonic distortion is a mere 0,03% at full rated power:  65 watts per channel,min. RMS, both channels driven into 8 ohms from 20-20,000 Hz.
The Sansui G-6000 DC receiver is much more than its extraordinary amplifier circuitry. It is also a superb FM section, with excellent sensitivity, selectivity and signal-to-noise ratio, virtually without distortion. The G-6000 also gives you high-technology protection circuitry that keeps both your speakers and receiver safe, always it offers perfectly positioned and highly accurate power, tuning and signal meters. And human engineering, for greatest easy-of-operation. The G-6000 is also elegantly styled with a beautiful simulated walnut grain finish.
