The Sansui AU-919 set the industry standard for amplifier excellence.
Now, there's a tuner good enough to match: the digital-controlled, quartz-locked TU-919.
It takes a lot to complement the performance of an amplifier good enough to have become the standard to the industry Sansui's ultra-high speed AU-919*, with its Diamond Differential DC circuitry (patent pending), eclipses all previous DC amplifier designs. Consider an amplifier with TIM so low that it can barely be measured. The effect is of enormous importance to the ultimate tonal quality of the music you hear. And that may be one of the many reasons why the AU-919 made such a sensational debut among music lovers 200V/µSec. slew rate. 0.5µSec. rise time. Frequency response from zero Hz (DC) to 500,000Hz. DD/DC phono equalizer, accurate to ± 0.2dB from 20-23,000Hz. And selectable DC operation straight through from Aux. input to speaker output.
The result is on extraordinarily clean sound quality and uniquely accurate music reproduction in every important performance characteristic. Sansui's newest tuner perfectly complements this superior amplifier.
The Sansui TU-919 is super-high technology through and through. Unlike some so-called digital tuners, the TU-919 doesn't just provide a digital read-out for an analog tuning system. Sansui's patented, self-correcting digital circuitry, with wide-range lock-in to a precision quartz reference oscillator provides drift-free tuning to-lowest distortion (0.03% mono, 0.05% stereo). And an in credible sensitivity of 8.7dBf (1.5µV IHF T-100), with 50dB quieting at only 12.5dBf.
With this unique technology, we frankly don't need the wide, frequency-linear dial arid center-tune meters in FM. The digital tuning circuitry automatically locks the TU-919 onto the selected station to minimize distortion and interference effects. S/N is 86dB, and capture ratio a superb 0.8dB. Even when the tuning knob is touched or the unit bumped, the station remains locked in. Always.
To maximize selectivity and minimize distortion, wide and narrow selectable bandwidths are included not only for FM, but also for AM. And the AM section of the TU-919 is perhaps the only true Hi-Fi AM available today--which is really important if you listen to AM, or live in an area where AM predominates.
To ensure that your AU-919 can give you the full pleasure of additional performance capabilities, Sansui engineers have included more technological innovations in the TU-919. Flat group-delay response, for lowest distortion, isn't in the IF section alone: our unique circuitry extends back to the RF front end as well. The output stage of the TU-919 uses the Sansui pure DC configuration to match the outstandingly high slew rate and low TIM of our DC audio amplifiers.
The design, engineering and performance characteristics of bath the AU-919 and TU-919 are measurably superior. But the real proof of their excellence is in the sound. Come listen. At your nearest authorized Sansui dealer. Today.
