WE

THANK

YOU

VERY

MUCH

FOR

YOUR

PURCHASE

OF

OUR

AKAI

GX-266D.

By

employing

an

automatic

two-way

recording

mechanism

and

giving

full

play

to

the

advantages

of

the

4-track

system,

this

machine

enables

continuous

long-hour

recordings.

Being

designed

and

developed

to

allow

free

utilization

as

a

master

deck,

the

unit

is

equipped

with

many

functions

including

a

recording

mute

mechanism

with

a

timing

lamp

and

a

timer

start

switch.

Please

read

the

contents

of

this

Operator’s

Manual

carefully

before

operating

the

machine

to

give

full

play

to

all

the

functions

and

to

enjoy

the

pleasure

of

tape

recording

to

the

utmost.

BEFORE

OPERATING

THE

GX-266D

In

installing

this

machine,

care

must

be

taken

to

avoid

such

places

as

those

shown

below

as

they

will

cause

disorders.

®

Places

exposed

to

heat

radiated

from

heating

appliances

or

to

direct

sunshine

Places

of

high

temperatures

Dusty

places

Places

subjected

to

vibrations

Places

affected

by

magnetism

Precautions

should

also

be

taken

with

respect

to

the

following

points.

©

As

this

appliance

is

quite

heavy,

it

will

be

dangerous

in

the

event

it

turns

over,

@

Do

not

place

heavy

objects

over

the

power

cord,

or

insert

the

cord

in

objects

with

pointed

corners

as

it

will

lead

to

damaging

or

disconnecting

the

cord,

creating

serious

danger.

©

As

unexpected

troubles

may

result

from

metallic

pieces

such

as

hair

pins

that

has

dropped

inside

the

unit,

ALWAYS

KEEP

HEADS

CLEAN

The

GX

Heads

not

only

have

superior

electromagnetic

preperties

and

durability

but

also

have

the

feature

of

repelling

dust.

However,

the

heads

should

always

be

cleaned

before

making

important

recordings,

especially

when

tapes

edited

by

splicing

tapes

are

used.

To

maintain

stable

tape

travel,

clean

those

places

in

the

neighborhood

of

the

Capstan

and

Heads

that

come

in

contact

with

the

tape

{ie.,

Tension

Arm,

Sensing

Pin,

Capstan,

Tape

Guide,

etc.)

from

time

to

time.

Excessive

cleaning

of

the

Pinch

Roller

should

be

avoided

as

the

roller

is

susceptible

to

corrosion

by

chemicals.

(At

an

average

daily

use

of

1

hour,

consider

once-a-week

cleaning

to

be

sufficient.)

MAKE

[fT

A

PRACTICE

TO

DEMAGNETIZE

HEADS

Before

recording

or

playback,

make

it

a

practice

to

demagnetize

heads.

the

head-demagnetizing

method,

please

refer

SYSTEM

In

the

4-track

system,

the

width

of

the

tape

is

divided

into

four

and

each

one

fourth

can

be

used

independently,

while

in

the

2-channel

system,

two

tracks—one

for

the

left

channel

and

one

for the

right—are

used

for

a

single

recording

or

playback.

Track

1

and

Track

3

are

used

respectively

for

the

left

and

right

channels,

whereas

on

the

reverse

side,

Track

4

and

Track

are

used

respectively

for

the

GENERAL

PRECAUTIONS

IN

TAPE

HANDLING

©

Be

careful

not

to

touch

tape’s

magnetic

surface

with

fingers

as

it

will

become

a

source

of

drop-out.

©

No

recording

can

be

made

on

the

leader

tapes

at

both

ends

(first

part

and

end

of

reel)

of

the

tape.

Thus,

before

starting,

take

up

the

leader

tape.

@

Full

care

must

be

taken

in

tape

handling

when

using

thin

tape

(200%

and

above:

e.g.,

when

tape

of

a

740m

length

(2,400ft)

is

used

with

Small

Hub

7

inch

Reel).

Long-period

storage

of

tapes

that

was

taken

up

in

a

fast-forward

or

rewind

mode

will

cause

damage

to

the

tape,

leading

to

unexpected

troubles

or

will

make

them

unfit

for

use.

Therefore,

the

tapes

should

be

stored

in

a

condition

as

taken

up

in

an

orderly

manner,

with

the

tape

traveling

at

the

fixed

speed

of

Recording

or

Playback.

However,

either

rewind

or

fast-forward

the

entire

to

flash

at

intervals

of

HOW

TO

SET

RECORDING

INPUT

LEVEL

Since

sensitivity

will

vary

according

to

the

tape

used,

the

best

way

to

set

the

recording

input

level

will

be

to

adjust

the

Input

Controls

(with

the

unit

in

the

RECORDING

mode

and

the

Monitor

Switch

positioned

to

TAPE)

in

a

manner

to

bring

it

close

to

“‘OVU”’

when

the

swing

of

the

VU

Meter’s

indicator

is

maximum.

Even

if

the

left

and

right

Input

Controls

are

positioned

somewhat

differently,

the

level

indicated

on

the

VU

meter

should

be

considered

as

the

standard

for

all

adjustments

and

therefore,

level

adjust-

ments

should

be

effected

centering

on

the

VU

Meters.

This

will

ensure

the

best

recording

level.

Because

this

machine

is

equipped

with

GX

Heads,

not

only

has

loss

been

minimized

during

recording

and

playback

but

recording

without

any

distortion

is

possible

even

when

the

level

exceeds

‘““OVU’’

when

using

the

wide

dynamic-range,

high-performance

tape.

Further,

at

recording,

the

level

can

be

raised

to

the

highest

possible

range

without

distortion

by

simultaneous

monitor-

ing.

By

raising

the

level,

the

dynamic

range

becomes

that

much

wider,

enabling

recording

with

excellent

S/N

ratio.

*

Depending

on

the

recording

input,

the

VU

Meter

will

not

indicate

distortion

that

has

generated

in

the

recordings

on

the

tape.

Even

in

such

cases,

the

presence

of

any

distortion

can

be

checked

through

simultaneous

monitoring.

HOW

TO

USE

MEMORY

MARKER

In

the

playback

of

sources

such

as

music,

if

the

number

is

suddenly

started

in

a

large

volume,

or

if

it

suddenly

ends

in

an

abrupt

manner,

the

effect

would

be

quite

unnatural.

To

avoid

such

phenomena

from

occurring,

such

recording

techniques

are

employed

as

those

known

as

FADE-IN,

which

is

the

technique

in

which

recording

is

started

in

a

small

volume

and

then

is

gradually

raised

until

the

optimum

volume

is

reached,

or

FADE-OUT,

in

which,

the

sound

at

the

end

of

the

number

is

graduaily

diminished

from

an

optimum

volume.

To

effect

FADE-IN,.

the

Recording

Input

Control

is

gradually

tuned

up

until

the

volume

reaches

an

optimum

recording

level.

Thus,

it

is

necessary

to

have

the

position

of

the

optimum

recording

level

marked

in

advance.

Mean-

while,

in

the

case

of

FADE-OUT,

the

Input

Control

is

gradually

tuned

down

from

the

position

of

the

optimum

recording

level.

In

this

case

too,

it

is

necessary

to

have

the

position

of

the

optimum

recording

level

marked.

Since

the

Memory

Marker

is

not

interlocked

with

the

movement

of

the

Input

Control,

it

is

capable

of

indicating

the

position

of

the

optimum

recording

level

at

all

times.

Notably

for

FADE-IN,

in

which

the

Input

Control

is

tuned

from

minimum

up

to

the

optimum-level

position,

it

is

important

that

the

optimum

position

of

the

Input

Control

be

indicated

in

advance.

The

Memory

Marker,

by

being

set

to

the

optimum

volume

position,

thus

offers

convenience

in

FADE-IN

and

FADE-

OUT

operations.

SIMULTANEOUS

MONITORING

This

is

the

method

by

which

the

condition

of

recording

that

is

taking

place

on

the

tape

is

confirmed

during

recording

operations.

By

making

use

of

this

method,

it

is

possible

to

confirm

whether

an

important

program

is

being

positively

recorded

or

not.

or

to

check

for

any

distortion

due

to

overlevel

recordings.

TO

USE

CONTROL

Confirm

that

connections

conform

to

the

“BASIC

CON-

NECTIONS”’.

This

machine

is

equipped

with

a

variable

control

that

enables

the

line

output

to

be

varied

from

0

up

toa

maximum

level

of

0.775V

(during

When

an

external

is

employed,

it is

necessary

to

match

the

line

output

level

of

the

deck

with

the

line

input

level

of

the

external

amplifier.

Consider

the

standard

volume

of

the

amplifier

to

be

the

volume

at

which

one

ordinarily

listens

to

FM

broadcasts

of

a

receiver

or

a

tuner,

and

keep

the

volume

control

at

this

position.

Then

position

the

If

the

Line

the

the

case,

the
