TPIONEE,
SOME UNIQUE FEATURES:
aFM front - end employing a field effect
transistor to hear more stations more clearly
olntegrated circuit (lC) employed in FM tuner
assures outstanding capture ratio with high
reliability.
oMultiplex circuitry (MPX) for maximum
channel separation
oUnique muting circuit permits the easiest
tuning control
oHigh performance single ended push-pull
(SEPP) output stage eliminates audio
transformers and provides large output with
true frequency fidelity
oFull complement of inputs and outputs
By the use of FET (field effect transistor) in the FM radio frequency ampl fier
stage, design of nearly perfect FM front-end was achieved-free from cross
modulation, f ree f rom drift, with better sensitivity, lower inhere nt noise, and
high spurious rejection ratio.
ln the Fl\4 intermediate frequency amplifier stage, integrated circuits are employed,
resulting in an entrely different outstanding performance from that of lFstages
hitherto designed, especially in the limiter characteristic and the capture ratro.
The accurate electronic switching circuitry is employed in the FM multiplex
demodulator, insuring maximum separation with excellent tonal quality.
The mutrng circuit provided in the FM tuner completely elim nates the FM
inter-station noise which has hrtherto been annoying the user in tuning.
The power amplif ier employs the hlgh-performance single ended push,pull
circuitry in the output stage and the push pull complementary ctrcuitry in the
driver stage, completely eliminating the distortion inherent transformers from
the audio stage. Tripple diffused mesa transistors are adopted as the power
transistors in the output stage for full-fidelity frequency response with large
audio output power and least harmonic distortion.
The inputs and outputs provided in the receiver include two pairs of pllONO
MAG inputs. When two turntables are connected to these inputs, the user
is able to switch from one turntable to the other any time at wrll. AIso. two
pairs of loudspeaker outputs are included for switching between, or for per-
mitting the simultaneous use of, two loudspeakers.
The electronic switching circuitry employed in the power supply cornpletely protects
expensive power transistors even when the loudspeaker leads are shorted wh le
the recerver unit is in use.

LINE VOLTAGE SEI.ECTION AND FUSE
Switching Line Voltage Setting and Fuse
In order to remove the fuse, turn the fuse cap located on the
line voltage selector switch in the direction indicated by an arrow.
Then remove the fuse plug from the unit. Put the fuse plug
back so that the proper line voltage marking can be seen thru
the cut on the edge of the plug.
Whenever the set position of the selector switch is changed,
check the rating of the fuse. A 1.5-ampere fuse is to be used
for either 220Y or 240 V operation and a 3-ampere fuse for
any of 110V, 117V, or 13OV operation. lf the rating of the
fuse is proper, install the fuse on the fuse cap.

PION
Antenna
and Ground Connections:
AM antenna
OThe ferrite loopstick antenna (18) mounted on the rear of the
receiver will provide satisfactory reception of local stations
with strong signals. Because the loopstick antenna has di-
rective properties, its direction may be adjusted for the best
reception while listening to a station.
Fig. 6
Olf noise is strong in your area and the ad;ustment of the
loopstick antenna direction does not improve the situation, the
furnished AM lead antenna may be laid on the wall or on
other standing object as high as possible, and one end of the
antenna lead should be connected to the AM antenna terminal
Q2).lt the furnished antenna dose not help, an outdoor AM
antenna may need to be set up. ln this case, the antenna
lead should also be connected to the AM antenna terminal
122).
FM Antenna
Olf the receiver is situated in regions close to the transmitting
site or is placed in a wooden building, the furnished simple
indoor T-shaped antenna wili provide satisfactory results. In
this case, the 2 wires of the twin leads from the antenna
should be connected to the FM antenna terminals (24) and
the horizontal element of the T-section should be extended
and positioned for the best reception while listening to an FM
station. Then, the antenna should be secured to the wall or
to any support.
Oln regions where the f urnished indoor T-shaped antenna provides
poor results such as many noises or poor channel separation,
an outdoor FM antenna may be required. ln this case, the leads
from the outdoor antenna should also be connected to the
FM antenna terminals (24).
For information about the outdoor FNI antenna, consult a
TV shop in Your area.
OG rou nd
ln some area, the use of a proper ground reduces noise sig'
nlficantly. The lead from an appropriate grounding electrode
such as a water pipe or a ground rod, is connected to GROUND
TERMINAL (23).
Loudspeaker Gonnections
OTwo loudspeaker systems, the main and the extra , (the left
and right channel loudspeakers per system or four loudspeakers
in total) may be connected to the receiver. Note, however, that
the impedance of each channel loudspeaker must be larger
than four ohms when two loudspeaker systems are connected
to the receiver Model SX-15OOTO /SX-1500T.
OAs shown in Fig. 8, the loudspeaker leads are connected to
the speaker plug furnished with this receiver. ln this case, be
sure that the positive loudspeaker lead is connected to the
positive terminal on ihe plug with reference to Fig.8 .

1. Whether you plan to listen to FM-monaural or FM stereo
broadcasts, first set the SELECTOR switch (5) to the FM-AUTO
position, and the MODE/TAPE M0N SWITCH(17)to the MODE-
STEREO position.
OThe Model SX-1500TO /SX-1500T is equipped with an FM
mono/stereo automatic switching circuit which serves to
identify an FM signal automatically as either a mono or a
stereo signal. Monaural signals are reproduced in mono,
and stereo signals are automaically reproduced in stereo.
When a stereo signal is received and reproduced, the stereo
indicator light will go on.
2. The MUTING switch (14) is set to the MUTING position. lf,
however, the receiving signal is weak in your area, leave this
switch in the OFF position.
3. Set the AFC switch (15) to the OFF position, and then tune
in a desired station with the TUNING CONTR0L (4) while
observing the TUNING INDICATOR (3) for pinpoint accuracy
in tuning.
4. After the desired station has been tuned in accurately, the
AFC switch is set to the AFC position to activate the auto-
matic frequency control circuit.
NOTES: 1. With the SELECTOR(5) set to the FM-AUTO position,
if an extremely weak stereo broadcast is received,
the receiver willautomatically switch to mono operation.
2. lf you wish to reproduce FM stereo broadcasts in
mono, or if there is excessive noise with the SE-
LECTOR(5)set to the FM-AUTO position and tonal
quality is impaired, set the SELECTOR (5) to the FtVt-
lVl0NO position. ln this case, the lVlODE,zTApE M0N
switch (17) may be set to either NIODE- LEFT or
IVIODE.RIGHT.
Reception of AM Broadcasts
1. The SELECTOR switch(5)is set to the AM position. The MODE/
TAPE MON switch (17) may be set to any of |VIODE STEREO,
MODE LEFT, or MODE-RlGHT.
2. The desired station is tuned in by means of the TUNING
control (4) while observing the TUNTNG IND|CATOR (3)
Record Reproduction
1. The SELECTOR switch (5) is set to the PHONO position.
2. For reproducing the turntable outputs fed to the PHONO 1
input jacks (26), the PHON0 switch (16) is set to the pHONO
1 position, and for reproducing the turntable outputs fed to
the PHONO 2 input jacks Q7), the switch (16) is set to the
PHONO 2 position.
OWhen using a turntable equipped with either ceramic pickup
type cartndge or crystal pickup type cartridge, the setting
of the PHONO switch (16) can be set to any position.
3. The MODE/TAPE MON switch (17) is now set to the MODE-
STERE0 position. However, when using a monaural turntable,
it should be set to either the MODE-LEFT or MODE-RIGHT
position, depending upon which channel input the output
cable of the turntable is connected to.
Direct reproduction of tape head outputs
OWhen the signal directly derived from the playback head of a
tape deck is reproduced through this receiver, the operation
will be as follows:
1. The SELECTOR switch (5) is set to either the TAPE HD 7 I/z
or TAPE HD 33/4 position, depending upon the speed at
which the tape is to be played back.
2. The MODE/TAPE MON switch (17) is now set to the IVIODE
STEREO position. However, when a monaural tape deck is
used, it should be set to either the M0DE-LEFT or IVODE-
RIGHT position depending upon which of the two input
channels the output cable from the tape deck is connected
to.
Note: For playback of a mono material using a stereo tape deck,
the |VIODE/TAPE MON switch (17) should be set to either
the MODE'LEFT or IVIODE-RIGHT position, depending upon
which track the material is recorded on.
Recording and Playback Using
Tape Recorder
oRecording
1. The signals of the program being reproduced through the
loud speakers are always present at the TAPE REC output
jacks (32). Therefore, the SELECT0R switch (5) and IV0DE/
TAPE MON switch (17) are appropriately set to select an
optional program source in the normal manner for reproduction
through the loudspeakers. Then, the signals from the TAPE
REC output jacks (32) can be recorded on the tape recorder.
Note: The VOLUIVIE, BASS, and TREBLE controls of the Model
SX'l500TG),/SX-1500T do not affect the sounds being
recorded. The recording level should be adjusted with the
level controls of the tape recorder.
oPlayback
1. For stereo playback, the M0DE,zTAPE M0N switch (17) is set
to the TAPE MON-STEREO position. For playback of mono
material using a monaural or stereo tape recorder, the MODE/
TAPE MON switch (17) may be set to either the TAPE MON-
LEFT or TAPE MON-RIGET position.
oTape Monitoring
When using a 2-or 3-head tape recorder equipped with a
monitor circuit, by making all connections for recording and
playback, it will be possible to monttor the recording in progess
by moving the MODE,UTAPE MON switch (17) from the MODE-
STEREO position to the TAPE IVION,STEREO position. In the
case of a Z-head tape recorder, the signal being fed to the
recording head will be monitored, and in the cass of a 3-head
tape recorder, the signals recorded on the tape will immediately
be monitored by the playback head picking up the recorded

CONDITIONS FREQUENTLY MISTAKEN TO TROUBLES
Noise: There are a variety of noises relating to the operation
of a hi'fi unit. These are generally divided into two types; (1)
the unit is sick (a transistor or part is deteriorated) and (2) an
external source of noise is giving noise to the unit.
When a hi-fi unit produces an unpleasant noise, it is frequently
judged that the unit is sick, but a statistical record indicates
that the majority of noises produced in a hi fi acoustic unit is
resulted from external scurces of noise. Due to the inherent
high sensitivity and also the high fidelity in reproduction, the
unit amplifies and reproduces the high extraneous nojses, how,
ever small, lf your receiver produces a noise. check the follow
ing table and trace out the source of noise for an appropriate
corrective action,
The table includes the conditions that may be mistaken to the
troubles of the unit.
