IMPORTANT
PRECAUTIONS
To keep the set in
top
condition
all the
time,
observe
these precautions.
1.
Do
not
obstruct
the
ventilation
opening
of
the
cabinet.
2.
Avoid
an
extremely
hot
or
dusty place
or
a place
very near some heating appliance.
3.
Nine
pin
jack covers are
supplied
with
the set.
Be
sure
to
insert these cover
into
the unused
pin
jacks on
the rear panel
to
avoid dust
accumulation
.
4.
If
the set •
is
placed on a shelf, be sure
that
the shelf
board
is
thick
and strong.
HEAT RADIATED
BY
THE
SET
As
transistors are sensitive
to
heat, the enclosure
of
this set
is
designed
to
provide
a
good
dissipation
of
the
heat radiated inside this set. Thus,
if
you place some-
thing
on
top
of
the
ventilation
opening
of
the enclosure
or
place the set inside a closed box, and operate
it
for
many hours,
it
is
possible
that
the set breaks
down
.
Always
try
to
provide
a
good
circulation
of
air around
the
set.
But
removing
the enclosure
or
the
bottom
plate
to
allow
good
ventilation
is
not
only
dangerous
but
undesirable
from
the
standpoint
of
electrical per-
formance.
AC OUTLETS
Of
the three AC outlets
provided
on the rear panel,
the one marked 'SWITCHED'
is
controlled
by
the
front-
panel POWER
switch
.
It
is
convenient
to
use
it
to
power
a program source
component
such
as
your
turn-
table.
If
you keep the
power
switch
of
such a
com-
ponent
turned on, then
that
component
will
be turned
on and
off
as
you
operate the POWER
switch
of
this
set.
The
other
two
AC outlets, marked 'UNSWITCHED,'
are
not
related
to
the set's POWER switch. The voltage
delivered at these AC outlets
is
the same
as
the
power
supply
voltage used.
The 'SWITCHED'
outlet
has
a 100-watt capacity. The
two
'UNSWITCHED' outlets have a
combined
capacity
of
250
watts.
Do
not
connect
any
equipment
whose
power
consumption
exceeds the capacity
of
each
out-
lets,
as
it
is
extremely
dangerous. The
power
consump-
tion
rating
is
usually listed in the specification chart
of
the
equipment,
or
sometimes on the
equipment
itself.

If
you are
connecting
one pa
ir
of speaker systems
to
the set,
they
may
have any impedance
from
4
to
16
ohms. Connect them
to
the
SPEAKERS
SYSTEM-A
or
-8
terminals
on
the real panel, making sure
not
to
confuse
the
left
and
right
cables
or
the plus and minus leads on
the set and speaker ends.
The set also connects
two pa
ir
s of speaker systems.
Thus,
for
instance, one
pair
connected
to
the real-panel
SPEAKERS
SYSTEM-A terminals
may
be used in
your
own
room,
while
the
other
pair
(SYSTEM-8) in a separate
living
room
. And
if
you have connected
two
pairs
of
speaker systems and
wish
to
drive
them all simultane-
ously
by
turning
the
SPEAKERS
switch
to
A+B,
each
speaker system
should
have
an
impedance
of
more
than
8 ohms. The impedance
is
usually specified
on
the
system itself
or
in its specification. Using a system
with
a
lower
impedance
could
result in a
breakdown
of
the
set;
doing
so
will
reduce the
composite
speaker
im-
pedance in each channel
to
less
than 4 ohms.

CONNECTING
HEADPHONES
Headphone are connected

the
PHONES
jack on the
front
panel. Sound comes
from
the connected speaker
systems
too
unl
ess
the
SPEAKERS
switch
on the
front
panel
is
in its
OFF
position
. Therefore,
to
listen
pri-
vately
with
the headphones
only,
turn the
SPEAKERS
switch
to
OFF
.
IF
SPEAKER
SYSTEMS
ARE
OUT
OF
PHASE
If
you
were
careless
when
connecting
the speaker
systems and
if
the plus and minus polarities are
not
in
the same
order
for
the l
eft
speaker system and the
right
speaker system,
they
would
be reverse-phased. This
will
cause a '
dropout'
of
sound at the extreme ends and
the
middle
of
the
line
between the
two
speaker systems,
creating a sense
of
discontinuation
and damaging the
sense
of
stereo perspective. Also, the
bass
sound
would
lose
much
of
its powerfulness and become rather
unnatural.
Once
that
condition
is
corrected and the polarities are
in order,
you
can
detect
it
by
reproducing
a stereo
or
mono
source
with
the
MODE
switch
of

G) POWER Switch
Raise the lever switch to ON to turn the set on, push
it down to OFF to turn it off.
2. SELECTING SPEAKER
SYSTEMS
® SPEAKERS Switch
The set connects up to two pairs of speaker systems,
and this
switch allows selection of either or both pairs
of the connected speaker systems.
OFF: To cut off the sound from the speaker systems
when listening with headphones.
A: To drive the speaker systems connected to the rear-
panel SPEAKERS SYSTEM-A terminals.
B: To drive those connected to the SYSTEM-8 terminals.
A+ B: To drive both A and B pairs of speaker systems
simultaneously.
3. SELECTING PROGRAM
SOURCE
@ SELECTOR Switch
Adjust to the program source (except tape) you wish
to hear such as records and radio broadcasts or AUX.
PHO NO-2, PHO NO-1: For playing records. The im-
pedance of the PHON0-1 circuit can be switched
over with the PHON0-1 Pickup Load Switch on the
rear panel to match the impedance
with the approved
. load resistance
of the cartridge in use .
TU NE R: To hear radio broadcasts through a connected
tuner.
AU X-1, AU X-2: To reproduce whatever program source
is connected to the rear-panel AUX-1 or AUX-2 inputs.
@ TAPE PLAY Switch
Use it to reproduce a recorded tape or to monitor a
recording that you are making. Turn
it to the position
that covers the record/playback circuit connecting the
tape deck in use at the
moment. At all other times,
leave it in the normal "SOURCE"
position .
[> When one tape deck is connected to the set:
DECK-1, D EC K-2: To reproduce a recorded tape on the
tape deck connected to therear-panel
TAPE DECK-1
or TAPE DECK-2 terminals.
SO UR CE: To hear the program source, selected by the
SELECTOR switch.
[> When two tape decks are connected to the set:
C OPY 1 ► 2: To dub or reprint a recorded tape on the
tape deck (in playback mode) connected to the rear-
panel
TAPE DECK-1 terminals onto a tape on another
tape deck (in record mode) connected to the rear-
panel
TAPE DECK-2 terminals.
D EC K-2: •To monitor a recording as you dub it to
Deck 2 in record mode .
D EC K-1: To hear the program source as the signal
leaves Deck 1 in playback mode.
C OPY 2 ► 1: To dub or reprint a recorded tape on the
deck connected to the rear-panel TAPE DECK-2 ter-
minals onto a tape on another tape deck connected
to the
TAPE DECK-1 terminals.
D EC K-1: To monitor a recording as you dub it to
Deck 1 in record mode.
D EC K-2:· To hear the program source as signal leaves
Deck 2 in playback mode.
eMonitoring
is possible only if the tape deck in record
mode is equipped with separate record and playback
heads.
4. STEREO VS. MONO
® MODE Switch
When you are going to hear a stereo program source:
Leave this
switch at NORMAL. If you have connected
the left and right speaker systems in reverse, set this
switch to REVERSE to restore the normal stereo effect
without physically changing the speaker connections.
When you are going to hear a mono program source:
Set the switch to MO 0, then the monophonic mixture
of the left and right channel signals is heard from both
speaker syste ms . The switch should be in this position
to hear a monophonic source (record or tape) on a
turntable or tape deck, connected to either the l eft or
right input terminals on the rear panel.
e
To hear either the left or right channel signal, turn
the BALANCE control fully clockwise or counterclock-
wise.
5. ADJUSTMENT OF VOLUME
@ VOLUME Control
(J) MUTING Switch
The overall volume is controlled by the VOLUME
control. The more this control is turned clockwise the
louder the volume of the sound becomes.
Use the MUTING switch when you wish to reduce
the overall volume te
mporari ly. This attenuates the
volume by 30dB ' ( lower position) or 15dB (upper posi-
tion) without having to touch the main VOLUME con-
trol, which comes in very handy when you receive a
telephone call
or to eliminate the unp leasant sounds
produced when the styl us is lowered onto the surface
of the record.
eAdjustment of the volume of very low sounds is
easily carried out by adjusting the VOLUME control
after the MUTING switch has been set to the '- 15dB'
position.

HEADPHONE JACK
Plug stereo headphones into this jack for private
listening
or monitoring . But be sure to turn the SPEAK-
ERS switch to OFF first unless someone is listening to
the sound from speaker systems in another
room .
• The numbers indicated in the photograph above coincide
with the colored switch designations.
6. LEFT & RIGHT BALANCE
ADJUSTMENTS
@ BALANCE Control
@ MODE Switch
The volume of the left and right speakers can be
adjusted'
by the BALANCE control (the outer ring around
the VOLUME control).
As the control is turned counter-
clockwise from the center
position the sound from the
left speaker becomes
louder than that from the right
speaker. When turned clockwise
from the center, the
sound from the right speaker increases
in volume as
compared with that of the left.
Stereo balance adjustments are made
by pushing
down the MODE switch and then adjusting the BALANCE
control so that the sound you are listening to can be
heard from the exact center
position between both
speakers.
Reset the switch to its original "NORMAL" positions
by raising it.
If in this case you can sense some differ-
ence in the volume between the left and right speakers,
recheck the program source side (stylus pressure bal-
ance, etc.).
WHEN YOU HEAR ABSOLUTELY
NO SOUND FROM THE SET :
Some of the symptoms and conditions which
seem to indicate a breakdown of the set are caused
by wrong operation or by faulty external com-
ponents. These can be spotted with a simple ex-
amination and restored
to normal. If you suspect
a breakdown, please confirm the connections and
your operating procedure once more.
Check List
of Operation
1. Is the POWER switch turned on?
2. Is the TAPE PLAY switch in a position other
than "SOURCE" although you
do not wish to re-
produce a recorded tape?
3. Is the SELECTOR switch tu,rned to the correct
position?
4. Is the SPEAKERS switch turned to the correct
position?
5. Is the PRE / MAIN SEPARATE switch on the rear
panel in the "CONNECTED" position?
Check List
of Connections
1. Is the power cord plugged off a wall AC outlet?
2. Are the connection cords for your turntable and
tape deck loose
or touching some other object?
3. Are the speaker connection cords loose or de-
tached
from the set or your speakers?
4. Does each speaker system have an impedance
of more than 8 ohms when you have connected
two pairs of speaker systems and what to drive
them simultaneously
by turning the SPEAKERS
switch to A+ B? Otherwise, the quick-acting fuses
protecting the
power transistors may have blown.

TONAL QUALITY
@TONE &
FILTER Switch
@) BASS Tone Selector
@ TREBLE Tone Selector
@ BASS Control
@) MIDRANGE Control
@ TREBLE Control
To control sound, first push the TONE & FILTER switch
down to the "TONE & FILTER" position .
The strength of low-frequency sound such as is pro-
duced by a bass is adjusted with the BASS control.
Turning it clockwise from the center emphasizes the
lows ; turning it counterclockwise de-emphasizes them .
Set
the BASS Tone Selector to one of its three positions :
600Hz, 300Hz
or 150Hz. The selector selects the fre-
quency below which the BASS control functions.
The strength of mid-frequency sound such as is pro-
duced by a singer's vocal chords is adjusted with the
MIDRANGE control. Turning it clockwise from the
center emphasizes the midrange, and turning it counter -
clockwise de-emphasizes them. The frequency at
which the MIDRANGE control functions is 1kHz .
Likewise, the strength of high-frequency sound such
as generated by cymbals is adjusted with the TREBLE
control. Operation is the same as for the BASS and
MIDRANGE
controls . The TREBLE Tone Selector selects
the frequency (2kHz, 4kHz or 8kHz) over which the
TREBLE control functions .
ewhen you do not want to adjust the tone control
itself to have a flat response, set the TONE & FILTER
switch to the DEFEAT position . Or when you do not
want to adjust the tone control itself but do want to
e liminate low- or high-frequency noise, set the switch
to the FILTER ONLY position . In the DEFEAT position,
the entire tone control and filter circuits are separated
irre s pective of positions of triple tone controls and
filter switches .
@) LOUDNESS Switch
The human ear becoms inse nsitive to the lows and
highs
as sound volume is reduced. So you may feel a
loss
of highs and lows (especially lows) when listening
at a low-volume level. The loudness circuit accents the
highs and lows properly to render the reproduced sound
more realistic. Setting the LOUDNESS switch to the
LOW BOOST position accents only the lows ; setting it
to the HIGH & LOW BOOST position accents both the
highs and
lows .
ELIMINATING NOISE
@ LOW FILTER Switch
@ HIGH FILTER Switch
To use the FILTER switches, set the TONE & FILTER
switch to FILTER ONLY . To use the FILTER switches and
TONE
controls, set it to TONE & FILTER.
Set the LOW FILTER switch to 60Hz or 20Hz to elimi-
nate disturbing low-frequency noise such as hum or
rumble of your turntable motor . Setting the switch
to 60Hz or 20Hz cuts the low-frequency noise below
that frequency .
Set
the HIGH FILTER switch to ?kHz or 12kHz to
eliminate disturbing high-frequency noise such as the
surface scratches of a worn record, hiss from a recorded
tape or as the fluorescent lamp noise mixed in radio
broadcasts. Setting the switch to ?kHz or 12kHz cuts
the high-frequency noise above that frequency .
eset the filter switches to the OUT position when the
high- or low-frequency noise is not irritating .

PLAYBACK PROCEDURE
1. Set the set's TAPE PLAY switch to either TAPE DECK-1
or TAPE DECK-2, depending on which tape play circuit
is connecting the tape deck in use.
2. Operate the tape deck
to start playback. .
3.
Adjust the various other controls and switches to
suit the type of program source you are going to hear.
RECORDING PROCEDURE
1. Prepare the program source you wish to record and
keep it ready to go. The SELECTOR switch must be
adjusted.
2. Operate the tape deck and start
recording . Adjust
the record levels with controls provided on the tape
deck. The
volume and tone controls on the set do not
affect the sound to be recorded.
3. To
monitor the sound being recorded, follow the
same procedure
as for playback after making certain
that the tape deck it s elf is adjusted to permit monitor-
ing. If the tape deck only has a combined record/ play-
back head, set the TAPE PLAY switch to the SOURCE
position and hear the sound before it is recorded.
■ CONNECTIONS
e Connect TAPE DECK REC term i•
nals with recording input terminals
or your tape deck, and PLAY term I•
nals, with its playback output

eAUX terminals may be used to
connect tape player (or deck) for
playback only. Use them when

are already occupied.
TAPE PLAYER (OR DECK)
CONNECTED TO
AUX
INPUTS
HOW TO US ETHE AUX TER M INALS
The term AUX is an abbreviation for auxiliary. If
your turntable has a crystal or ceramic cartridge, it
should be connected to the AUX terminals.
The AUX terminals have the same electrical function
as TAPE DECK PLAY terminals. So you can connect a
tape deck
or player to them if your TAPE DEC _K PL~Y
terminals arealready occupied. Playback
function will
be obtain ed.
A tuner
or an amplifier-equipped adaptor may also
be connected to the AUX terminals. The AUX terminals
have
an input sensitivity of 100 millivolts . So most
audio components having an output voltage of 100
millivolts or more can be connected. If you are not
certain whether you can connect a particular com-
ponent to the AUX terminals, look up its operating
manual
or specifications.
• DO NOT connect tape deck to

CONNECTION
CORDS
Be
sure
to
connect
your
turntable, tape deck and
speakers
firmly.
Be
careful
that
the
connection
plugs
are
not
loose
from
the jacks
or
the leads
of
the
con-
nection
cords are
not
touching
other
parts.
If
the
con-
nections are
imperfect,
noise may be generated and,
eventually, the set may break
down
.
It
is
advisable
to
follow
the instructions given
by
the manufacturer
of
the
equipment
you are connecting.
CONNECTION CORDS
WITH
RCA
TYPE
PLUGS:
These
are shielded cords
with
an
RCA ·
type
plug
so
ldered
to
each end. They are used
to
connect
a turntable, tape
deck and
other
program source components.
Try
to
keep the cords
as
short
as
possible.
If
you
use
lon
g
cords, the
high-frequency
signals
tend
to
be attenuated.
Their
maximum
length should be
two
meters (7 feet).
If
such cords are already
supplied
with
your
tape deck
or
turntable,
it
is
advisable
to
use
them
.
DIN
RECORD/
PLAYBACK
CORD: This
is
a
combined
2-channel stereo record/playback cord, standardized in
Germany. This set
has
a special
5-pin
socket marked
TAPE
REC
/
PLAY
on the rear panel
to
accept such a cord.
It
can be used
only
if
your
tape deck
has
an
identical
socket.
PVC
CORDS: These are used
to
connect
your
speak-
ers, and are basically the same
type
of
vinyl-covered
cords
as
the
power
cords
from
your
TV set
or
radio
.
Peel
the
vinyl
covering
off
each end
of
the cord, care-
fully
interwine
the lead wires, then
connect
it
to
your
speaker and the set. To prevent
mis-connection
,
it
is
advisable
to
paint-color
to
each cord.
Color-coded
cords are available at some appliance stores.
SHORT-CIRCUIT PIN
PLUGS
When
you unpack the set,
you'l
l find special
pin
plugs inserted
into
the PHONO-2 jacks. Their
function
is
to
short-circuit
the plus and minus terminals
of
the
input
cir
cu
it
and thus
pr
event a
ny
noise
from
being
generated
by
them
when
these jacks are
not
in
use.
Therefore,
if
you
use
the PHONO-2 jacks, r
e-position
these plugs
into
the PHONO-1 jacks.
Or
,
when
both
PHONO-1 and PHONO-2 jacks are used, keep them
elsewhere
for
later use.
Do
NOT
insert them
into
the
output
jacks (such
as
TAPE
REC),
or
the sound
from
the
set
will
be
cut
off
.
PRE
/
MAIN
SEPARATE
SWITCH
On
thi
s set the
output
terminals
of
the
pr
eamplifier
and the
input
terminals
of
the
power
amplifier
are con-
nected
by
the
PRE
/
MAIN
separate switch. To slide
it
to
the "SEPARATED"
position
separates the
preamplifier
from
the
power
amplifier,
allowing
you
to
use
them
independently
.
If
you
are
not
going
to
connect
an
ex-
ternal
preamplifier
or
power
amplifier
(or
some other
additional
unit)
to
these terminals, be sure
to
keep the
switch
to
the "CONNECTED"
position
. Also, whenever
you
try
to
slide the
switch,
be sure
to
turn the set's
POWER
switch
off
befor
ehand.
The separation
of
the
preamplifier
and the
power
amplifier
offers a
number
of
useful applications.
One
of
them
is
a so-called
electronic
crossover system. In
this system, each speaker
unit
(woofer,
midrange,
tweeter, etc.) in each speaker system
will
be driven
by
a
separate
power
amplifier
. But,
to
do
this, you
will
first
need
an
electronic
crossover
divider
. And,
of
course,
you
will
need one
or
two
stereo
power
amplifiers in
addition
to
the set's
own
power
amplifier,
depending
on
whether
you
wish
to
build
a 2-way
or
3-way electro-
nic
cross-over system. The speaker systems,
of
course,
must also be
2-way
or
3-way.
Once
all these
compo-
nents are ready, slide the
PRE
/
MAIN
separate
switch
to
the
"SEP
ARATED"
position,
and
connect
the
input
terminals
of
the
electronic
crossover
unit
with
the
PRE
OUT
terrr.inals
of
the set, and the
output
terminals
of
the crossover
unit
with
the
MAIN
IN terminals
of
the set.
Connect the
additional
amplifier(s)
so
the
electronic
crossover
unit,
and finally,
connect
the
output
terminals
of
the amplifier(s)
to
each speaker unit.

BEFORE
SENDING THE
SET
OUT
FOR
SERVICING
Some
of
the symptoms and
conditions
which
seem
to
indicate a
breakdown
of
the set are caused
by
wrong
operation
or
by external
components
. These can be
spotted
with
a simple examination and restored
to
normal.
If
you suspect a
breakdown,
please
confirm
the
connections and
your
operating
procedure
once
more
.
Here are
some
useful hints:
First,
if
you hear absolutely no sound
from
the set,
inspect
your
turntable, tape deck and
other
program
source components, then examine this set and
your
speakers in that order, paying
attention
to
both
their
connections and operation.
Be
sure
to
reduce the
volume
beforehand.
Second,
if
the sound fails
to
come
out
only
when
you
play records, reproduce a recorded tape
or
receive
broadcasts, then chances are
that
only
the
particular
program source
component
may be
wrongly
connected.
If
loud
hum
noise
of
constant loudness
is
heard,
it
may
be
suppressed
by
connecting
the
grounding
lead
or
terminal
of
your
turntable
or
tape deck
to
the set's
GND
terminal, using PVC
cord
.
Or,
more
simply,
re-
versing the
connection
between the set's
power
cord
plus and the
wall
AC
outlet
may stop it.

and tape
deck loose
or
touching
some
other
object? Are you
using shielded cords?
3. Are the speaker
connection
cords loose
from
set
or
your
speakers?
After
you have made the above examination and made
the required corrections,
if
the set fails
to
operate
normally, there may be something
wrong
with
the
set itself. In such a
case,
please contact the dealer
from
whom
you purchased
it
or
your
nearest SANSUI
AUTHORIZED
SERVICE
STATION.
ABOUT
THE VOLTAGE ADJUSTMENT
Your
set
is
adjusted
to
operate at the correct
power
supply
vo
ltage
of
your
area
prior
to
shipment
from
our
factory.
If
you
move
after purchasing
it
or
send
it
as
a
gift
to
a
friend
living
in
an
area
where
the voltage
is
different,
it
may
be necessary
to
adjust its Voltage Selector.
To adjust
it,
remove
the
two
screws securing the
name
plate
on
the
rear panel, then set the
arrow
mark
on the Voltage Selector Plug
to
the
correct voltage
indication
(100, 117,
220
or
240
volts).
It
may be
necessary
to
replace the
power
fuse
as
well
whene-
ver the voltage
has
changed. For
operation
at
100
to
117
volts, use a 6-ampere fuse. For
operation
at
220
to
240
volts,
use
a 3-ampere one.
SHOULD
THE POWER
FUSE
BLOW
If
no Power
Indicator
should
glow
and the set
simply
remains dead even after
you
have turned on its POWER
switch,
it
is
possible
that
its
power
fuse
has
blown
.
If
this happens, disconnect
the
power
cord
from
the
wall
AC
outlet
at once and examine the
power
fuse on
the rear panel.
If
you
find
it
blown,
replace
it
with
a
new
glass-tubed fuse
of
the rated capacity (6-ampere
for
100
to
117
volts, 3-ampere
for
220
to
240
volts).
Never
use
a fuse
of
a
different
capacity
or
a piece
of
wire,
even
as
a stop-gap measure,
or
serious danger
could
result.
