OPERAT¡ON
PLAYBACK FROM
RECORD
DISC
ICONNECTIONS
Generally
a
record player
consists
of
a
turntable
ensuring
constant
rotation
of the
record disc
a
pick-up
(cartridge)
whose
stylus
(needle) traces
the
sound
groove
of
the
disc
converting
the
physical
signal
of
the
record sound
into
the
electric
signal,
and
the
arm which
holds
this
cartridge.
The
player
has
2
cords
with pin
plug
at
its
end
for
both
right
and
left
channels.
Connect
the pin
connectors
to
the
input
terminals of this
receiver
IPHONO-1(37)
or
PHONO-2(37)].
A
probable
earth
lead
of
player may
be
connected
to
the
GND
terminal(4O)
of
this receiver.
A
mains
cord
of
the
player
to
drive
its
motor
may be
connected
to lhe
con-
venient
extra
mains outlet(28)
(E
and
U
type
only).
This
receiver
is provided
with 2
input
terminals
(PHONO-1
and
PHONO-2)
to
be
selected
by
the input
selector
switch(
1
),
which is
useful
for
comparison
test
of 2
pick-
ups
or
using
2
record
players.
For
use
of
1 player
either
of
2
input
terminals
can be
selected.
ISIGNAL
PATHS
Put
the
disc
on the turntable, switch
on
the
phono motor,
and set
the
stylus
on the
groove
of disc.
Then
recorded
signals begin
to
be
fed
to
the receiver.
First,
signals
fed
to
the
receiver
through
PHONO
terminals
are
brought
to
the
equalizer
section, where
recorded signals are
equalized
and
restored
to
the
original frequency
curve.
lncidentally
this
equalizer curve
has
been
standardized
to the RIAA
curve.
The
equalized signals
are
then fed
to
the input
selector
swilch
(function
switch).
lf
th¡s switch
¡s
not
set at
the
correct
position
of
PHONO,
the
signals
are
blocked
here
and
no
more
advance
is possible.
Then
the
signals
are
divided
into
2
channels,
one line
to
the
recording
output
terminal,
and
the other
to
the
tape
monitor
switch,
Then
the tape
reprint
switch which
is
effective on
both
channels.
lf
the
monitor sw¡tch(11)
is
set
at the
"source"
position
the
signals are
sent
to
the
mode selector
switch,
and volume
control,
but
if
at the
"deck-1
"
or
"deck-2"
position
the
tape
monitor
terminals
start
to
f
unction
and
lhe
signals
are
stopped
at this
point.
Except
when the
tape playback
is
made
by
tape
monitor
terminals,
the
monitor switch
must
be kept at the
"source"
positon.
But when the
input
signals
are
fed
to
PHONO
or
AUX
terminals
recording
output
is
always
obtainable
regardless
of
the positíon
of
the
monitor
switch.
Then
the
signals
are sent
to
lhe
volume
control through the
mode
selector,
f
ilters,
and
loudness
control.
lf
the volume knob
is
turned
to
the
extreme
end
of
counter-clockwise
direction, the
signals
cannot
proceed
ahead.
lt
is
necessary
to
set
this control at the
optimum
volume.
Such controls as linear equalizer, low-cut
filter,
high-cut
filter,
loudness,
and tone controls are
for
flexible
and
diversified adjustment
of
playback sound
and
do not block
the
signals
completely.
Then the
signals reach
the
speaker
switches amplif
ied
by
the
main
amplifier.
Sound
playback
from
speaker systems is
thus
realized
if
the
speaker switch
corresponding
to
the
speaker
terminals
to
which
the
speakers
are connected
is set
at the correct
position.
The
above
is the feeding
path
of
PHONO signals
starting from
input
terminals
to
the
speaker
systems.
Difficult
as
it
may
sound
you
can
easily understand
it from
the attached block
diagram. For your
pleasant
command
of this
receiver
we
recommend
you
to
bear
the block
diagram
in
your
mind.
TPLAYBACK
PERFORMANCE
Now put
a disc
on
the turntable
for
playback
performance.
As the
volume
control
is
turned
clockwise
from the
cut
position,
playback sound
comes
out from
speakers.
As
explained
in the
paragraph
of
Sìgnal
Paths
the
sound
playback
is
possible
regardless
of
the
posìtion
of
[Vode
Selector etc.
as
far
as
these essentìal
controls
are
set
at
the
correct position such
as Input
Selector
Switch(1),
Tape
Dubbing
Switch(.1
0),
lVonitor
Switch(11),
Speaker
Selector
Swjtch(23) and
Volume
Control('l
2).
Now
all
preparations have been
completed.
Check
if
the
volume
levels
on
both right and left
speakers
are
identical. lf
deviated
adjust
it
by the
Volurre
Control.
For stereophonic
playback
see
to
¡t
that
the
lVode Selector
Swìtch
ìs
kept
at
the
"stereo" position,
otherwise correct
stereophonic
playback
is not
feasible.
PLAYBACK
OF AM/FM
BROADCASTING PROGRAM
Selection
of
the input
selector(
1
)
at
the AM
or
FM
position
ensures
playback
of
AIV
or
FM
broadcasting
programme,
lf
you want you
can connect
other
tuner
(AM, FM,
LW
or
SW
etc.)
to
one
of
the AUX
terminals
of
this receiver. ln this
case
the
selector must
be set
at
the
corresponding
position.
As
shown
in the block
diagram
the
input
signals
from
the tuner
sect¡on
on AUX
terminals
are
directly fed to the lnput
Selector
Switch.
Afterwards
the
signals
trace
the
same
blocks
as
explained
in the
para-
graph
of
Playback
from
Record Disc and
are
reproduced
from the
speaker
systems. Both
for
FM stereophonic
and
monaural
broadcasting
the
lVlode
Selector
Switch
can
be set
at the
position
of
"FfVl",
for
such
accommodation
to
the ìnput
source
can be
made
in
the tunersect¡on.
In
case
weak FM
stereo
is
received
and
you feel ìt
noisy,
set the
l\4ode
Selector
SwiÌch(
9
) at the
"mono"
position
for
better
reproduction.
ln
case
of
AM/LW
programme
from
other tuner there
is
possible
trouble
of
modulation
hum,
which
can be
eliminated
bV
varyinq
the
distance and
angle
of
these
components.
OTHER
TUNER
OTHER
PLAYBACK
The
signals
of flat
frequency
response
from
such
sources
as
TV
receivers
do not
need
an equalizer
stage,
and
for
play-
back
of
such
audio
equipments
any
of
these
AUX
termirrals
can
be
used,
Connection
arrd
operation
is same
with
that
of
AM/FN/I broadcasting
programme.
PLAYBACK
FROM
TAPE
TPLAYBACK FROM TAPE MONITOR TERMINALS
Almost
all
of
tape-recorders,
and
tape-decks currently
markeled integrate
audio
pre-amplifiers
in
their
circuit.
Also there ls
a
tape-player exclusively
for playback'
Con-
nect
the output terminal (LINE
OUT)
to
the
Tape I\4onitor
Termìnals(39). Then set
the
Monitor
Switch(11)
at
the
corresponding
position
and the
playback
from
tape
is realized
lf 2
tape-recorders
are
connected
to
the
Terminals(39), selection between
2
tape-recorders
is
possible
by the Monitor Switch(11).
This amplif ier
sectiot'r
can
be
devided
into
2
sections
-
one before
the
Recording
Output
Terminals(R
EC. OUT) and the other after
the
Tape lVonìtor
Switch,
and
3-head
tape-recorder
makes
it
feasible
to
make
recording
with the
former
section
and
simultaneously
to
make playback
with the
latter
section.
Note
lhat
normal
function
cannot
be
expected
if
2
sets
of
tape-recorder
for
playback are connected
to
the
terminals
of TAPE
IVIONITOR-1
and
Tape Connector(32)
at
the
same
time,
since these
2
are
coupled
in
the
inside
circuit
and
effect
each
other.
Therefore
if
Tape
Monitor
Terminals
and Tape Connector are
used
the
tape;recorders
should
be
connected
to
the
terminals
of
TAPE
MONITOR-2
and
the
Tape
Conrrector.
IPLAYBACK
FROM
AUX
TERMINALS
recorder
or
tape-deck
is
connected
to
the
AUX
terminals of
this
receiver
by
use
of
pin-jack lead and
the lnput
Selector
Switch is set
aÌ the
corresponding
position
to
the
AUX
Terminals.
All
operations ìn
this
case
are same
with
those
for the
Playback
of Tuner.
Note
that
when tape
playback
is
made thror.rgh
AUX
terminals,
the line input or
AUX
input
terminals
of
the
tape-recorder
should
not
be
con-
nected,
lf
connected
to
the
Recording
Output
Terminals
(REC.
OUT)
of
the
receiver
there
wìll
be
possible oscilla-
tion by
feed-back
of
signals.
IPLAYBACK
FROM
TAPE
CONNECTOR
This
connector is
of
DIN
norm, and very
convenient
for
simple
connection
by a
single
patch cord
between
the
tape-recorder
and
recordit.rg/playback connectors
of
this
receiver"
A
DIN
cord should be
connected between
DIN
connector
of
the
tape-recorder
and Tape Connector
of
this
receiver.
Playback
from
Tape Connector
is
possible
if
the
Monitor Switch
is set
at the
"deck-1"
positlon.
RECORDING
ON
TAPE
In
case
of
playback
of
various
programme sources through
ìnput
terminals
of
this amplifier, the
same
signals
to
these
reproduced
ln
speakers
are
available
at the
Recording
Outpu.t Terminals(38)
and Tape
ConnecÌor(32)
if
the
Tape
Dubbing
Switch
is set
at
the "source"
position.
By
connection
of
these term¡nals
to
the
¡nput
terminals
(AUX
or
LINE-lN)
of
the tape
recorder
you
can
enjoy
simultaneous
recording
and playback.
These
recording
signals
are
taken
out
before the Tape
Monitor
Switch
and
there
is
no
inf
luence
of
such controls
as
Volume
Controls,
Tone
Controls
and Fìlters
etc.
