DIRECT COUPLING PREAMPLIFIER SECTION

So that its dynamic range is very wide, the equalizer
circuit of the SA-500A uses two-stage direct coupling
negative feedback circuit with low-noise silicon transistors.
For professional tone control, the unit offers click-stop-type
individual bass and treble controls that allow you to increase
or decrease the audio signal delivered to the amplifier in
measured steps. Thus, signals delivered from the unit
sound the way you want them to.

POWER AMPLIFIER SECTION

The power amplifier section of the SA-500A is equipped
with quasi-complimentary single ended push-pull circuit
to ensure distortion-free sound reproduction and a wide
frequency response. Music power output of the unit is
44 watts (measured at 4 ohms), more than youll ever need
to fill your music room with spectacular solid sound. The
SA-500A can handle up to two different pairs of speaker
systems, either separately or simultaneously, giving you the
extra versatility of playing a small set of speakers in a room

adjacent to your regular music listening room. The unit
also lets you easily compare one set of speakers with
another, or lets you select the appropriate speaker unit
when systems are placed in different rooms.

TWO PHONOINPUTS

The SA-SOOA is equipped with all necessary input terminals
to allow you to build a perfect components system. It has
two sets of phono input terminals in addition to a tuner
and an auxiliary terminal. You may, if you wish, connect
two turntables simultaneously. Or you may also use the
jacks provided to compare two different cartridges or
turntables.

TWO TAPE DECK TERMINALS
The SA-500A has two pairs of TAPE REC and MONITOR

terminals so that you may operate two tape decks simulta-
neously, choosing from an open-reel deck, a cassette deck
or an 8-track cartridge tape deck. This feature permits
easy tape-to-tape duplicating.
