1

Press

the

POWER

switch

to

switch

on

the

deck.

2

Open

the

cassette

holder

using

the

EJECT

button

and

insert

the

cassette

you

want

to

record

on.

3

Set

the

BIAS

and

EQ

switches

according

to

the

tape

being

used

and

the

DOLBY

NR

switch

to

ON

if

you

want

to

make

a

Dolby

noise

reduction

recording.

Make

sure

that

the

BIAS/REC

CALIB-

RATION

button

is

in

the

PRE-SET

(11

)

position

unless

you

have

already

made

the

necessary

adjustments

required

to

use

this

facility.

Press

the

RECORD

and

PAUSE

buttons.

This

will

enable

you

to

adjust

the

record-

ing

level

without

actually

recording

on

the

tape.

5

Use

a

signal

from

a

tuner

or

amplifier

(plugged

into

the

LINE

IN

inputs)

or

from

microphones

plugged

into

the

MIC

jacks

and

adjust

the

recording

!evel

using

the

RECORD

controls.

§

From

a

fully

counterclockwise

position,

gradually

turn

up

the

RECORD

level

controls

until

the

loudest

sound

to

be

recorded

just

makes

the

meter

indica-

tion

reach

the

0

dB

point.

7

When

everything

is

set

up

and

ready

to

go,

set

the

tape

in

motion

by

pressing

the

play

(

>

)

button.

8

When

you

want

to

stop

recording,

press

the

STOP

button.

If

you

want

to

con-

tinue

recording

but

want

to

pause,

use

the

PAUSE

button

instead.

In

this

case

the

record

function

will

not

be

deacti-

vated

and

recording

will

resume

when

the

play

(

»

)

button

is

pressed

again.

>

Erasing

A

previously

recorded

tape

can

be

erased

on

the

deck

by

recording

the

entire

tape

with

the

MIC

and

LINE

controls

set

to

0.

Setting

the

Recording

Level

Setting

the

recording

level

correctly

is

essential

if

you

want

to

make

top

quality

recordings.

If

the

level

is

too

low

the

re-

cording

will

be

unnecessarily

noisy.

If

the

level

is

set

too

high,

the

recording

will

be

unnecessarily

distorted.

Generally

speaking

the

recording

level

should

be

set

so

that

the

loudest

signals

to

be

recorded

make

the

meters

indicate

OdB

BUT

NOT

MORE.

if

the

meters

peak

over

the

0

dB

point,

the

RECORD

level

controls

should

be

turned

down

a

little.

With

a

little

time

and

practice

you

will

be

able

to

select

that

critical

re-

cording

level

that

gives

you

the

best

hi-fi

recordings.

The

type

and

condition

of

the

tape,

as

well

as

the

type

of

music

source

you

are

recording

also

affects

the

optimum

settings

of

the

record

level.

Recording

with

Microphones

One

microphone

can

be

connected

to

the

L/MONO

jack

for

monaural

recording.

The

signal

will

be

automatically

fed

to

both

channels

(L

and

R).

If

both

RECORD

level

controls

are

set

the

same,

the

sound

will

be

“centered’’

between

the

channels.

By

raising

either

level

control,

the

sound

“‘image’’

can

be

made

to

move

toward

the

higher

level

channel.

This

is

true

also

when

using

two

microphones

for

stereo

recording.

Live

recordings

may

have

much

wider

dynamic

range

than

records

or

FM

stations,

so

be

sure

to

watch

the

peak

meters

to

make

sure

the

input

signal

doesn’t

exceed

0

dB

and

saturate

your

tape.

To

achieve

good

mic

requires practice

and

experience

and

is

usually

much

more

difficult

to

do

than

normal

copying

of

or

Dubbing

(Punch

Recording)

During

you

can

go

directly

from

mode

to

record

mode

by

holding

in

the

RECORD

button

and

pressing

the

play

(>

)

button

at

the

same

time.

The

deck

will

begin

recording

from

that

location

while

the

tape

continues

to

run.

This

opera-

tion

is

called

“punch

in”

recording

or

“running

splice’.

It

allows

you

to

record

over

or

correct

a

recorded

section

of

the

tape

without

stopping

the

tape

first

and

then

selecting

record

mode.

Record

Muting

The

capability

of

creating

clear

unrecorded

(erased)

portions

on

a

tape

during

recording

is

a

real

advantage

in

many

recording

situations.

For

instance,

you

may

want

to

eliminate

undesired

portions

of

an

FM

broadcast

that

you

are

recording,

such

as

commercials,

station

breaks,

or

announce-

ments.

You

may

want

to

record

a

complete

program

with

controlled

spacing

between

songs

that

can

be

filled

in

later

with

your

own

choice

of

material.

You

may

just

want

a

short

period

of

silence

between

each

song.

These

erased

portions

on

a

tape

could,

of

course,

be

created

using

a

deck

which

doesn't

have

the

record

muting

capability

of

the

TEAC

C-3,

but

the

operation

would

be

cumbersome

and

require

several

extra

steps

which

increases

the

chances

for

errors.

The

TEAC

C-3

makes

the

same

operation

smooth

and

simple.
