in a

horizontal

position.

3.

Power

source

This

unit

features a Direct-Drive

DC

Operated

Capstan

Motor

which

makes

it

possible

to

operate

on 50 Hz

or

60

Hz AC

line

voltage

without

any

conversion.

The

voltage

source

should

be

within ±5% or

the

unit's

rated

voltage.

Variations

in

excess

of

±10% of

rated

voltage

may

cause

uneven

performance,

or

possible

damage

to

the

unit.

One

of

the

most

important

factors

in

the

determination

of

regular

cleaning

of

the

Head

ABOUT CASSETTE TAPE

The

cassette

tape

used

in

this

unit

is

the

universal

type

used

throughout

the

world.

Notes

:

1.

Do

not

pull

the

tape

out

of

the

cassette

openings.

2.

If the

tape

is

loose

in

the

cassette,

the

tape

may

become

wound

onto

the

Pinch

Roller

and

result

in

breakage

or

damage

. If

the

tape

is

loose,

use a pen-

cil

as a

drive

shaft

to

rotate

the

reel

in

the

proper

direction

.

OK

NO

3.

Avoid

storing

this

unit

in

places

where

the

temper-

ature

and/or

the

humidity

is

high.

4.

If

the

tape

is

very

tightly

wound/or

unevenly

wound,

wind

and

rewind

it in

the

fast

forward

and

rewind

modes

before

use.

5. Use

high

quality

tape

upto

the

length

of C-90.

6.

Since

dirt

on

the

Head

or

Pinch

Roller

can

cause

tape

malfunctions,

these

parts

must

be

kept

clean,

as

instructed

in

the " MAINTENANCE"

section

on

page

10.

ACCIDENTAL-ERASE PREVENTION

Tape

cassettes

have

two

erase-prevention

tabs,

one

each

for

Side

1 and

Side

2.

When

these

tabs

are

removed

(by

using a screwiriver

or

similar

tool),

the

accidental-erase

prevention

system

of

the tape

deck

functions

to

prevent

accidental

erasure

of

the

original

recorded

material

(by

making

another

recording

over

the

original

material), and

thus

protects

valuable

recordings

from

loss

.

For

this

unit,

if

the

erase-prevention

tabs of a

cassete

have

been

removed,

the

unit's

accidental-erase

prevention

system

will

function

when

the

Record

Button

is

pressed:

the

Recording

Lamp

will

not

cannot

be

made.

~o

CASSETTE INSERTION AND REMOVAL

Insertion

1.

When

the

Eject

Button

is

pressed,

the

Cassette

Holder

will

move

outward

gently,

and

then

tilt

slightly

forward.

2.

Place

the

cassette

into

the

Cassette

Holder

so

that

the

edge

with

the

holes

(where

tape

can

be

seen)

is

facing

downward,

and

so

that

the

fully

wound

tape

is on

the

left.

3.

Close

the

Cassette

Holder

by

gently

pushing

the

center

part

(above

the

glass

window)

.

Note:

Be

sure

the

cassette

is

placed

so

that

the

edge

with

the

holes

is

facing

downward.

The

Cassette

Holder

cannot

be

closed

if

the

cassette

is

inserted

incorrectly

.

The

operation

buttons

of

this

unit

will

not

function

if

they

are

pressed

while

the

CASSETTE EJECTION MECHANISM

Be

careful

not

to

press

the

Eject

Button

while

the

tape

is

moving,

because

this

will

stop

the

operation

and

the

Cassette

Holder

will

open

.

FAST FORWARD AND REWIND

1.

When

the

Fast

Forward

Button

is

pressed,

the

tape

will

be

rapidly

forwarded

from

left

to right. When the

Rewind

Button

is

pressed, tape

will

be

rapidly

rewound

from

right

to

left.

2.

The

tape

will

stop

when

the

Stop

Button

is

pressed

.

3.

This

unit

has a fully-automatic-stop

system

which

stops

tape

movement

when

the

tape

reaches

its

end.

METAL

TAPE

A

word

about

"Metal

tape"

Conventional cassette

tape

s can

be broadly

classified

into

2

categories according

to

the

magnetic

material

coated

on

the

tape surface : the

ferric-oxide

(r-Fe

20 3)

type

including

ordinary

LH

tape,

etc

.;

and

the chrome-dioxide

(Cr0

2)

type.

Continued

technologi

cal

advances

have

been

made

in

an

attempt

to

develop

these

tapes

to a high

level

of

perform

-

ance,

but

recently

there

has

been a recognized need

for

the

development

of a

new

material

to

improve

performance

much

further.

In

response

to

this

need,

"Metal

tape" has

been

developed

as a new

kind

of

tape, employing a magnetic alloy

of

pure

iron

(Fe)

as

the

main

component

in

the

magnetic

substance.

In

comparison

with

conventional

cassette

tape

, "

Metal

tape

"

can

record a far

greater

amount

of

information

at a

high

density. As a result,

the max

imum

output

level

(MOL)

has

been

improved

throughout

the

entire

range,

and

, in

partic

-

ular, the

frequency

response

characteristics

at

high

levels

and

the

dynamic

range

in

the

high

range

have

been

greatly

improved

.

This

means, therefore, that a remarkable

improvement

of

sound

quality

has

been

made

possible

.

(It

should

be

noted

that

the

tape

base

and

parts

of

the

tape

other

than

the

magnetic

substance

are

composed

of

the

same

material

as

previously used.)

have

appeared

recently,

however,

and

the

FLUORESCENT LEVEL METER

The

FL

Level

Meter

of

this

unit

is a new

type

meter,

and

is

completely

different

in

principle

than

conventional

level

meters

which

have

indication

needles.

It

can,

however,

be

used

the

same

way

for

adjustment

of

the

recording

level.

During

playback

it

indicates

the

playback

level,

and

during

recording

it

indicates

the

recording

level.

In

addition,

because

the

meter

of

this

unit

can

be

used

for

both

peak

and

VU

indication,

it

is

possible

to

make

record-

ings

with a good

signal-to-noise

ratio,

with

little

distortion,

and

with

the

tape

recorded

to

its

very

limit

of

.

When

the

is

set

to

the

the

DOLBY RECORDING

This

unit

includes

the

Dolby

noise-reduction

system,

which

red

uces

tape

noise

to a rema

rkable

deg

ree.

Briefly,

the

system

works

as

follows : At

low

sound

levels

(whe

re

tape

noise

is

most

noticeable), the

high-frequency

portion

of the sound

is

recorded

at a

higher

level. Tape

noise

is no t

amplified

.

During

playback,

the

level

of on

ly

that

portion

of

the

signal

which

was

increased

at

the

time

of

the

rec o

rding

, as

well

as

tape

noise,

is

reduced

by a like

amount.

Thi s causes

the

signal

to

be

heard

at a

normal

level, and

the

tape

noise

to

be

reduced

significantly.

MULTIPLEX FILTER
