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

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
the set in the
MONO
position

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.

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.
