Sansui's unique DC amplifier circuitry.
Sound quality is what your audio system is all about. So your new receiver or amplifier should, above all, offer you audibly better music reproduction than what you have now or might buy at a comparable price. That's why Sansui created its unique DC amplifier circuitry, which lets you actually hear and appreciate the difference.
Sansui's DC amplifier section (patent pending) is used in all Sansui DC integrated amplifiers and DC receivers, including the AU-717 and G-5000. Either way, your music reproduction will be cleaner, richer and more true-to-life than you have ever heard before.
LOWEST POSSIBLE DISTORTION
Sansui receivers and amplifiers have long been recognized for their distortion-free sound reproduction, virtually eliminating harmonic and intermodulation distortion. Now. Sansui's new DC circuitry enables us to conquer even subtler imperfections, such as transient intermodulation distortion (TIM), caused by time delays or "phase shifts."
FASTEST RESPONSE
Sansui's DC amplifier section is designed without input, output, or negative feedback loop capacitors to eliminate low frequency phase distortion. And our exclusive dual compensation circuitry gives the high-speed, high-frequency response to achieve most accurate reproduction of the most demanding musical transients.
The speed/response capabilities of an amplifier are measured by its rise time which, for both the G-5000 and AU-717, is a mere 1.4 microseconds, corresponding to a frequency response that extends from zero Hz (DC) to 200,000Hz.
Slew rate tells you how large a transient burst an amplifier can handle. The G-5000 is rated to swing a signal level by 56 volts per millionth of a second, and the AU-717 is just a trifle faster.
The result of Sansui's unique DC design is audibly cleaner sound.
HUMAN ENGINEERING
In developing the most sophisticated amplification circuitry in the world, Sansui has not neglected the features that make components fun to run--for we believe that your audio components should provide not only superb music reproduction, but also great creative versatility. Both the AU and the G-series feature a full compliment of controls, logically arranged to make them a positive pleasure to operate.
THE G-5000 DC RECEIVER
Sansui's popularly priced G-5000 uses the same DC amplifier power design as Sansui's other, more costly models. It also incorporates our special new protective circuit that safeguards both your speakers and the G-5000 against mishap. Output is a usefully-powerful 45 watts per channel, min RMS, both channels driven into 8 ohms, from 20 to 20,000Hz, with no more than 0.03% total harmonic distortion.
THE AU-717 DC INTEGRATEID AMPLIFIER
If your choice is for separates rather than a receiver, Sansui suggests the rack-mountable AU-717 DC integrated amplifier. Our AU-717 has been acclaimed by the experts for its rare clarity of sound and for its superb versatility. Its DC power amplifier configuration means super-wide frequency response, with improved transient reproduction from the lowest lows to the highest highs. And the multitude of precise controls will meet your most sophisticated listening and recording needs. At 85 watts per channel, min RMS, both channels driven into 8 ohms, from 10 to 20,000Hz, with no more than 0.015% total harmonic distortion, the AU-717 is an unbeatable value for every music lover.
