Congratulations on joining the thousands of proud, satisfied owners
of quality stereo components frornSansui, Japans foremost spe-
cialist. '

In many ways, the '5500 is a culmination of Sansuis long experience
and arduous research in the design and manufacture of quality audio
equipment.

Its tuner section features an FET-equipped sensitive FM frontend
and an IC-equipped FM IF amplifier for outstanding FM selectivity
and superb tone quality. Its amplifier sectionis a masterpiece de-
signed, tested and proven to bring out every subtle shade of original
sound, regardless of the program source. Over-all, the receiver is
equipped with practically all the switches, controls, inputs and out-
puts that you would ever need to enjoy todays most advanced high
fidelity sound reproduction. -

So that you can take maximum advantage of its built-in versatility
and high performance, may we suggest that you read this manual
once carefullyi Our past servicing records indicate that most re-
quests for servicing were a result of wrong operation or the negli-
gence of simple maintenance. Should you ever encounter an
apparent fault of the receiver (such as the absence of sound), it is
advised to consult this manual first and examine the various con-
nections and your operating procedureonce.
