SOLID STATE INTEGRATED AMPLIFIER This professional
stereo component, an integrated amplifier with unusually wide power
bandwidth, says a lot about the way Japan's foremost audio-only
specialist meets the demanding requirements of the stereo world
today. A perfect power match for the TUv7500 stereo tuner, the AU-
7500 represents a significant milestone in Sansuis pursuit of excel-
lence. Not only are these two products the most advanced of any
2~channel products ever made by Sansui, they also represent the
pinnacle of the companys up-to-the-minute knowledge of audio
acoustics and electronics. The AU-7500 boasts such performance
characteristics as total harmonic distortion and intermodulation dis-
tortion which has been limited to below 0.1% throughout the audio
spectrum and well beyond. With its super-wide power bandwidth of

5-40.000Hz, you can achieve RMS power of 43 watts into 8 ohms,
along with total harmonic distortion of only 0.1%. inside theAU-7500
are a PNP-NPN-PNP heterojunction three~stage direct-coupled equali-
zer amplifier with an input capacity of no less than 300mV RMS re-
sulting in such a wide dynamic range. There are also low-noise PNF
transistor tone control circuits and a direct-coupled OCL pure com-
plementary power amplifier employing two 6,800,:1F jumbo power
supply capacitors. Finally, this professional amplifier is blessed with
a variety of convenience features, including a 4-channel adaptor
switch, the ability to connect up to three tape decks, and provisions
for tape-to-tape dubbing. And in terms of tonal quality, the AU-7500
quite simply has no equal.

AM/FM MULTIPLEX STEREO TUNER The TU-7500 tuner is
a perfect complement to the AU-7500. It fulfills, and then some, its
most fundamental requirement which, simply, is the ability to receive
any station at any time and any place with superb tonal quality.
Sansui engineers devoted extra research hours in accomplishing
this quality, and the results are not only noticeable, they are obvious.
Particular attention in the design of the TU-7500 was placed on the
phase characteristics, a property often overlooked in tuner design

but one that has considerable bearing on the quality of the sound you
hear. This is especially true-and significant-in light of the new
era of 4-channel sound field reproduction. All in all, the TU-7500
offers excellent phase linearity throughout, which means for you an
improved distortion factor, signal-to-noise ratio and stability. And,
best of all, when it is matched with the AU-7500, you have an un-
paralleled combination of audio design and manufacture. From
Sansui, the audio-only specialists.
