THE DIGITAL READOUTS ON THE NEW SANSUI RECEIVERS ARE NOT WHAT COUNT.
OUR PATENTED, DIGITALLY QUARTZ-LOCKED TUNING DOES.
DIGITAL READOUTS
While digital readouts may Improve the looks of a receiver and make it easier to use, only digital circuitry can Improve the receiver's performance. That's why the new Sansui Double-Digital receivers use our patented Digitally Quartz-Locked Tuning System, too.
DIGITALLY QUARTZ-LOCKED TUNING
To meet its rated distortion specifications, a receiver's tuner section must be perfectly center-tuned. The slightest mistuning causes distortion of the final signal to increase rapidly. And even if a tuner is accurately tuned initially, it may drift away from the desired frequency within a short time.
Sansui's Digitally Quartz-Locked Tuning System automatically provides optimum tuning that not only remains perfect while you listen, but stays on the same center frequency even if the receiver is turned off and back on again later.
Conventional quartz-controlled tuners use an analog phase reference circuit that may lose accuracy as a result of harmonic interference. Sansui's patented digital tuning system actually counts the vibrations of a quartz-crystal time-base and compares it to the tuned-in frequency for instant corrections.
When you listen to any of the new Sansui Double-Digital receivers, you'll immediately hear the difference that perfect tuning mates.
You’ll also see the difference in the specs. The tuning sections are extremely sensitive, with unusually high signal-to-noise and spurious response ratios.
PURE POWER DC AMPLIFICATION
A great receiver needs more than a superb tuner section. The amplifier must be first rate, too. That's why Sansui uses our own unique Pure Dower DC amplification system in all of our Double-Digital receivers.
While some other receivers hove low Total Harmonic Distortion (THD), a Sansui DC receiver can achieve lowest Transient Intermodulation Distortion (TIM) simultaneously That's because our high slew rote, fast rise lime DC circuits provides sufficient drive current to respond instantaneously to even the most fleeting musical transients The music-reproduction is remarkably life like, crisp and clean.
ELECTRONIC LED POWER METERS
The all-new peak power level LED display gives you an instantaneous reading of the power output of each channel, so you can continuously monitor the power you're sending to your speakers. This electronic indicator responds much faster and more accurately than any conventional needle-type meter.
ALL THE EXTRAS, TOO
The new Sansui receivers are high technology through and through. So we've designed them with special protection devices to prevent any mishap. Protective circuits save the output transistors from excessive current and keep too much direct current from your speakers.
And we haven't forgotten about the controls and features that make it possible fcr you to fine-tune the music. Like the bass and treble controls, which operate with an absolute minimum of distortion.. And tone defeat switch plus audio muting on our top three models. The volume controls with 41 click-stops, and ultra-smooth tuning knobs, are large and centrally placed for ease of operation. Taping, toot is simple, with versatile and complete facilities.

Everyone is proud of a great-sounding, high performance receiver. But you should be proud of its looks as well. With Sansui, you will be.
Ask your authorized Sansui dealer to show you one of our Double-Digital receivers.
Ask him to turn it on. You'll see that your music never had it so good.. And you never heard it better. That's something you can count on.
