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

plug

at its

end for both right

and

left channels.

Connect

the

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

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
