FEATURES
Power to Spare for Low Distortion
The pure complementary OCL circuitry employs high:
reliability NPN and PNP silicon power transistors, a
differential first stage and direct coupling at all stages. The
result is superb frequency response, output bandwidth
and distortion characteristics. 20W per channel provides
ample reserves of power for rich and stable stereo repro-

All Program Sources can be Played
The rear panel is provided with special input jacks for
turntable, tuner and tape deck, plus AUX jacks for
cartridge tape player deck, etc. Virtually all program
sources can be enjoyed.
Accepts 2 Sets of Speaker Systems
The SA-6300 is equipped with 2 sets of speaker terminals
and a speaker selector switch. Comparison listening of 2
speaker systems, or simultaneous operation of speakers in
different rooms can be performed by single switch

duction.
~ IC Equalizer Section
RIAA deviation, the most important factor in record
reproduction, is minimized by the IC equalizer section to
provide advanced fidelity. Transistorized constant current
circuits are employed throughout, increasing the accept-
able dynamic margin. Low distortion record playback,
with a wide dynamic range, can thus be enjoyed.
New Design Underscores Performance Quality
Simple, elegant front panel design provides built-in
operational ease. A matching stereo tuner is also available
for composing an easy to use high performance stereo
system.

STEREO SYSTEM SET-UP
The SA-6300 is an integrated stereo amplifier,
meaning that it combines a pre-amplifier and
power
amplifier
in
one
unit.
For
your
stereo
system,
you
will
need
at
least
one
pair
of
speaker
systems
and
one
program
source
such
as
a
turn-
table,
a
stereo
tuner,
or
a
tape
deck.
These
should
be
of
comparable
high
quality
to
the
SA-6300.
INSTALLATION CAUTIONS
Avoid installing the SA-6300 in locations such as
the following.
e In direct sunlight, near radiators or other heat
sources,
e Humid or dusty surroundings. —
@ Unlevel or unstable supports, or where subject
to vibration.

SPEAKER CONNECTION
The SA-6300 is provided with 2 sets of speaker
output terminals, A and B.A pair of speakers
should normally be connected to the A terminals.
e As shown in Fig. 2, connect the right chan-
nel (as viewed from the front) speaker to
the R terminals, and the left channel speaker to
the L terminals.
@ Observe plus (+: red) and minus (-: black)
polarities of the output terminals and those of
the
speakers.

NOTE:
If 2 sets of speaker systems (A & B) are to be used simultaneously
be sure that all speakers systems are 89 or more in impedance.
Damage may be caused of if speakers of less than 8Q are employed.
A WORD ABOUT ROOM ACOUSTICS
The sound heard from an audio system is greatly
influenced by conditions in the listening room.
The size and shape of the room, materials
composing the walls, ceiling and floor, the amount
and distribution of furniture, carpets, draperies, etc.
all affect the resulting sound. In general it is
advisable to place speakers with their backs against
a wall, as this will improve bass response.
Bare rooms with low ceilings, hard floors and hard,
reflective walls (especially a hard wall facing the
speakers) can produce an excessively ‘“‘live’’ bril-
liant sound with lack of clear instrument localiza-
tion and definition. It often helps in such cases to
place a carpet and heavy, soft curtains in the room.
Conversely, a ‘“‘dead’”? sound can be caused in
rooms containing heavy carpeting and a large
amount of upholstered furniture. This can often be
improved by re-arranging the furniture.

Connection Via REC/PB Connector
Instead of the recording and playback connection
just described, the tape deck can be connected to
the TAPE REC/PB connector (DIN type) of the
SA-6300 provided an identical connector is fitted
to the tape deck. The single DIN-cable completes
all playback and recording connections at the same
time.
Note that the REC/PB connector corresponds to
TAPE PB and TAPE REC jacks — the signal must
be controlled by means of the TAPE MONITOR
switch on the SA-6300. |

OPERATION
PLAYING RECORDS
1. Set the FUNCTION switch to PHONO.
2. Play record on the turntable.
3. Adjust the VOLUME, BASS and TREBLE
controls for desired volume and tone.
NOTES -
e Lower the tonearm stylus gently onto the record. Temporarily
lowering
the
VOLUME
control
will
reduce
the
noise
which
sometimes occurs when the tonearm touches down.
@ Do not turn off the power while the stylus is in contact with
the record.
® Avoid imparting vibration to the turntable while a record is
being played. This may cause the stylus to jump and possibly
damage the record.
@ Howling may be caused if the turntable is too close to the
speaker systems. Allow for adequate spacing when installing.
EMPLOYING TUNER
1. Set the FUNCTION switch to TUNER.
2. Tune in the desired station on the tuner.
3. Adjust the VOLUME, BASS & TREBLE controls
for desired volume and tone.

EMPLOYING TAPE DECK
TAPE PLAYBACK
As shown in Fig. 7, the tape deck is connected to
TAPE PB jacks.
1. Set the TAPE MONITOR switch to ON.
2. Play tape on tape deck.
3. Adjust the VOLUME, BASS & TREBLE
controls for desired volume and tone.
NOTE:
Turning the TAPE MONITOR switch ON enables tape playback
whatever the setting of the FUNCTION switch.

TAPE RECORDING
As shown in Fig. 8, the tape deck is connected to
TAPE REC jacks.
1. Set the FUNCTION switch to the source to be
recorded (PHONO, TUNER, etc.).
2. Operate the program source.
3. Adjust recording levels with the tape deck
- controls and proceed with recording.
NOTE:
The SA-6300 VOLUME, BASS & TREBLE controls have no effect
upon the signal at the TAPE REC jacks. The signal is recorded as it
comes from the program source and must be adjusted with the
controls on the tape deck.
TAPE DECK

Monitoring Recording Conditions
If the tape deck is a 3-head type recording
conditions can be monitored through the speakers
or headphones by setting the TAPE MONITOR
switch to ON. Both recording and playback con-
nections must be made in this case.
TAPE DUPLICATION AND EDITING
By employing two tape decks, selected material
from a previously recorded tape can be edited onto
a second tape. A personal tape library can be
compiled in this manner.
1. Connect two tape decks as shown in Fig. 9.
2. Set the FUNCTION switch to AUX, and operate
the tape deck connected to the AUX jacks as the
program source.
3. Record the program onto the tape deck con-
nected to the TAPE terminals, controlling the
recording level by means of the controls on
that deck.
To monitor the recording while duplicating set
the TAPE MONITOR switch to ON.
