OPERATING INSTRUCTIONS

SA-GSOOII are designed to operate 220V or 240V (HG model) main and
110V, 120V, 220V or 240V (S model) main. Before turning on the power,
please confirm the line voltage setting indicated on the rear of your unit
corresponds to the supply voltage in your area; if not, change the setting as

FEATURES

Power Amplifier Design Stresses Superb Tone and
Minimized Distortion

PNP differential amplifier first stage, all stages direct
coupled pure complementary OCL circuit delivers effortless
and beautiful stereophonic sound.

Continuous Power Output is 30 watts per
channel,min.RMS,at 8 ohms or 4 ohms from
20 Hertz to 20,000 Hertz with no more than
0.1% total harmonic distortion.

Both vigorous and delicate musical passages are reproduced
with exquisite clarity.

Differential ist Stage 4 Stage Direct Coupled
Equalizer

Due to the extremely minute signals involved, utmost
precision is demanded in the phono equalizer section.
Every effort must be made to obtain reduced distortion
and high signal-to-noise ratio. To fulfill these requirements,
the 5A76500ll utilizes a high performance low noise IC
which incorporates a four stage direct coupled circuit with
a differential amplifier first stage in the equalizer section.
Since open gain characteristics of the ist stage differential
amplifier are unusually fine, by applying thorough negative
feedback (NFB), low distortion, high Signal-to-Noise
ratio and high stability are obtained covering a wide
frequency band.

Enjoy Full Record Performance

Wide dynamic range and precise equalization curve result
from the strict quality control program used for selecting
the equalizer elements. Frequency response deviation,
which governs record playback, becomes held to within
10.3dB. Since high voltage is supplied by the balanced
positive and negative power supply system, with respect to
2.5 mV sensitivity, maximum phono input becomes 200
mVrms (at 1 kHz, 0.1% T.H.D.). All the rich grandeur of

the recorded sound can be reproduced with plenty of spare
margin.

11 Point Click Stop Tone Controls

Low and high frequency tones can be accurately adjusted
to match phono cartridge and speaker system frequency
characteristics, listening room acoustics, or your personal
tastes. The ll point click stop bass and treble controls
allow precise tone adjustments, plus easy return to
preferred settings for particular program sources. A tone
defeat (TONE) switch is also provided for instantly
bypassing the tone control circuits to obtain a flat response.
This is a highly convenient function for such applications
as evaluating tone control effectiveness.

Protection and Muting Circuits for Reliability and
Listening Comfort

Fused, electronic protection circuit includes a triac device
and operates to protect power amplifier and speaker
systems in event of malfunction. Surge noise when
operating the power switch is also prevented by the built-in
muting circuit.

Versatile Dual Tape Facilities

Two sets each of stereo tape recording jacks, tape playback
jacks and tape monitor switches are provided. These allow
connection of two tape decks for convenient tape
duplication, editing and transfer of open reel recordings
to easily handled cassettes.
