FEATURES
Ample Margin Power Amplifier
High reliability NPN and PNP silicon power transistors are
employed together with a differential first stage. All stages
are direct coupled in a pure complementary OCL circuit
design. This combination of superior components and
circuit design results in excellent frequency response and
distortion characteristics, plus plenty of extra power for
effortless sound reproduction.
Versatile Tone Control Section
TURN OVER switches are provided for the conventional
BASS and TREBLE controls to allow selection of the
frequencies at which the controls take effect. An important
TONE switch is also included for obtaining flat frequency
response at any time without regard to the tone control
settings. System sound can be composed or evaluated ac-
cording to cartridge, speaker, and listening room charac-
teristics.
Precise RlAA Equalization
Ultra-precision grade metalized film resistors (sputtering
process) and styrene capacitors are combined as equalized
elements. Deviation from the RlAA curve has been reduced
by 10.2dB in the frequency range of 30Hz ~ lSkHz. An FET
is employed in the lst stage differential amplifier and by
adopting a 3-stage direct coupled SEPP circuit, input
impedance variation due to frequency is minimized. High
stability is attained at low distortion, in addition to a greatly
expanded acceptable input level. Distortionless disc repro-
duction can therefore by enjoyed, even with a high output
cartridge and a dynamic music source containing large peak
inputs.
All Program Sources can be Enjoyed
A full array of input jacks permits connection of 2 turn-
tables, 2 tape decks, a stereo tuner, and 2 auxiliary com-
ponents. Wide flexibility is provided for employing vir-
tually any kind of program source.

Reliable Electronic Protection Circuit
In event of speaker shorting or malfunction in which DC is
applied to the output, speakers and transistors are reliably
guarded by an electronic protection circuit. This circuit also
acts as a muting circuit when the power switch is turned on
and off.
Accurate Volume Control Expands Adjustment
Range
The Volume control is equipped with a precision attenu-
ator of the type employed in measuring instruments and
other high reliability equipment. Volume adjustment can be
easily performed when listening at low volume levels, temv
porarily reducing the volume, or employing a low input
level (high gain) power amplifier. The volume adjustment
range can also be expanded by employing the volume
control and attenuator switch in combination.
Phono 2 lacks Provided with Impedance Selector &
Level Control
A convenient impedance selector switch (35kfl, SOkQ,
70kS2, lOOkSZ) and level control (0 ~ ol2dB) are provided
for the PHONO 2 jacks for matching cartridge output
characteristics, comparison listening, etc.
Tape Switch for Easy Tape Duplication
8y connecting 2 tape decks, the desired program only from
a previously recorded tape can be edited and re-recorded.
The Duplicate switch also lets open reel tape be duplicated
onto cassette tape.
Audiophile Functions Incorporated
A PRE/POWER AMP selector switch plus PRE OUT and
POWER lN jacks are included. An external power amplifier
can be connected to the PRE OUT jacks to allow listening
comparison and power amplification. This feature can also
be employed for composing a multi-amplifier or 4 channel
system. A single SA-QSOO can thus be used to set up various
kinds of audio systems.
