The Sansui A-80:

Few Amplifiers Can Equal Its Fidelity.

This DC-Servo amplifier
has very low THD, wide frequency
response and-best of all-very rich
musical sound.

Yes, this integrated amplifier has

a DC-Servo power amp: Cleaner sound

is assured.

In the A-8O DC-Servo means sound thats pure
as pure can be these days. All stages inside the power amplifier
are direct coupled. All capacitors in the signal path are eliminated.
We've added nothing, thus lost nothing. There are no capacitors
used that can add harmful coloration to music.

No wonder sound is exceptionally clean in the
A-80. The DC-Servo controls ultra-low-lrequency signals (all
those below 1H2) so that they cant reach your speakers. Which
means you can, if you have to. play warped records and still
hear good sound.

Power output is a comfortable 65 watts per chan-
nel. min. RMS, both channels driven into 8 ohms, from 20 to
20.000Hz. with no more than 0.05% total harmonic distortion.
All thisfrom an OCL (Output Capacitorless) true complementary
circuitwith a DC-Servo system. builtaround adependable opamp
(operational-amp) lC, for good, clean, dependable performance.

MC, MM or lM?

You might have a favorite type of

phono cartridge. Whatever it is, you can

play it through the A-80.

Some people say that the sound quality achieved
through an MO or Moving Coil phono cartridge is more transient,
crisperthanfrom MM (Moving Magnet) orlM (Induced Magnet)
types. Sansui is taking no sides in the issue. but we do make it
easier to use all types of phono cartridges in the A-80. For
example, we include a phono equalizer of exceptionally good
performance capabilities. RIAA equalization, noise and distortion
factors are tops. And if you prefer your MC cartridge. you needn't
buy an expensive, bulky step-up transformer" for it. Just hook
up your MC to the builtein ore-preamp." It automatically matches
impedance. it provides high dynamic range because it uses low
noise J-FET input and true complementary SEPP output circuitry
in the ICL (input Capacitoreless) design.

Power! Power! Power!

And heavy-duty Power Meters and LED

Peak-Power Display to help you control it.

Do you know how much power you should feed
to your speaker systems? If you do (and you should) you also
know that too much power can cause distortion, while too little
can allow noise to increase. The pair of large. heavy-duty power
meters on the A-80 help you control the output of the power
amplifier so that your speakers always operate at optimum levels.
The Peak Power Display (using five LED or Light-Emitting
Diode indicators) reads the momentary peaks which the meters
themselves (registering 0.1 watts to 100 watts) might miss.
