Tank you for selecting the Sansui AU-666 Solid-State Stereo
Amplifier, an excellent choice that will become more apparent
after years of rich stereo listening.

Sansui is known throughout the world for the unsurpassed qua-
lity of its audio equipment line, be it a control amplifier, a stereo
receiver, a speaker system, a turntable, a tape deck or a stereo
headset, and takes the greatest efforts to merit and maintain this
reputation.

The AU-666 is no exception. It features the refined dull black
panels common to all AU series professional control amplifiers
from Sansui, the direct-coupled complementary circuits in the
power amplifier section and the exclusive Triple Tone Controls in
the preamplifier section. Special provisions have also been made
to permit the amplifier to be built up into an electronic crossover
system and permit comparing such a system with a standard stereo
set up. This manual has been prepared to aid you in keeping the
AU-666 working perfectly. Please read the contents of this
manual carefully before installing or operating the amplifier. You
will then be able to enjoy the worlds highest standards of sound
reproduction to the fullest.
