CONGRATULATIONS!

Your

MT3X

Multitrack

Cassette

Recorder

is

a

fine

creative

tool

that

will

enable

you

to

work

with

sound

in

many

ways.

Whether

you

need

to

record

acoustic

instruments

or

voice

using

microphones,

electronic

instruments

and

sources

via

direct

line,

or

a

creative

blend

of

the

two,

the

MT3X

makes'the

process

of

building

up

your

own

sound

extraordinarily

smooth

and

simple.

You

can

simply

record

and

remix

four

tracks,

or

use

the

multitrack

“ping-pong"

recording

tech¬

nique

to

individually

record

up

to

ten

independent

parts

—adding

sound

layer

by

layer

until

you

create

exactly

the

ar¬

rangement

and

texture

your

imagination

demands.

There’s

even

a

sophisticated

auto

punch-in!out

feature

that

lets

you

re-record

a

section

of

a

previously

recorded

track

with

automated

convenience.

The

MT3X

is

just

as

easy

to

use

alone

or

with

a

band.

And,

because

it's

a

YAMAHA,

you

know

that

the

MT3X

will

give

you

the

very

finest

sound

quality

and

overall

performance

available.

In

order

to

make

use

of

the

MT3X’s

many

features

and

obtain

maximum

performance,

we

urge

you

to

read

this

opera¬

tion

manual

thoroughly

—

and

keep

it

in

a

safe

place

for

later

reference.

BEFORE

OPERATION

■

THE

DIFFERENCE

BETWEEN

TRACKS

AND

CHANNELS

The

words

“track”

and

“channel”

are

often

confused.

In

order

to

properly

operate

this

unit,

it

is

necessary

to

under¬

stand

the

meanings

of

these

terms.

TRACK:

The

“band”

on

the

tape

itself

where

a

certain

signal

is

recorded.

The

tape

inside

a

cassette

has

four

different

tracks,

enabling

the

recording

of

four

distinct

signals.

For

conventional

recordings,

there

are

two

tracks

(ste¬

reo

left

and

right)

on

each

of

the

tape.

CHANNEL:

The

route

of

a

signal

input

or

output.

In

the

input

side,

this

unit

has

six

INPUT

channels

and

two

AUX

chan¬

nels.

The

output

side

consists

of

one

stereo

channel

(made

up

of

two

mono

channels)

and

an

AUX

channel.

The

diagram

shows

how

a

conventional

stereo

cas¬

sette

deck

records

and

plays

back

music.

The

four

tracks

on

a

cassette

tape

represent

the

left

and

right

(for

stereo)

sound

for

each

side

of

the

tape.

The

MT3X

uses

these

four

tracks

for

single-direction

recording

and

playback

on

only

one

side

of

a

cassette

tape.

Conventional

stereo

cassette

recorders

always

record

and

play

back

in

the

same

mode,

with

the

tape

side

(direction)

determining

which

two

tracks

will

be

used.

These

recorders

do

not

allow

separate

selection

of

tracks

for

recording

and

playback.

Multitrack

recorders,

however,

allow

you

to

record

or

playback

tracks

separately

as

you

choose.

This

en¬

ables

a

degree

of

recording

and

playback

freedom

not

possible

with

conventional

cassette

recorders.

ABOUT

CASSETTE

TAPES

This

unit

is

designed

to

be

used

only

with

Chromeposition

tape,

and

will

not

work

properly

with

Ferrichrome

tape

formulations.

Cr02tape

(Bias:

HIGH;

EQ:

70ps)

should

be

used.

Also,

the

use

of

C-120

tapes

is

not

recommended

because

they

exhibit

poorer

performance,

and

can

be

the

cause

of

equipment

failure.

•

Preventing

accidental

erasure

of

recordings

To

keep

from

inadvertently

erasing

a

prFzed

recording,

all

cassette

tapes

have

record

protection

tabs

along

the

top

edge

of

the

cassette

shell.

If

this

tab

is

broken

out

using

a

screwdriver

or

any

other

appropriate

imple¬

ment,

it

will

not

be

possible

to

record

on

the

corre¬

sponding

side

of

the

tape.

This

will

protect

your

record¬

ings

from

accidental

erasure.

For

4-track

recording,

it’s

necessary

to

break

out

the

tabs

for

both

the

A

and

B

sides

of

the

tape.

When

you’d

like

to

record

over

a

tape

with

the

tabs

broken

out,

just

cover

the

holes

(where

the

tabs

were)

with

tape.

•

PREVENTING

ACCIDENTAL

TAPE

ERASURE:

•

Storing

cassette

tapes

To

prevent

tape

slack,

fit

a

stopper

into

the

tape

or

keep

tapes

in

their

cases.

Do

not

store

tapes

in

direct

sunlight,

or

in

places

with

high

heat

or

humidity,

as

this

may

damage

the

tapes.

Also,

keep

the

tapes

away

from

magnetic

fields,

such

as

near

televisions

or

speakers,

because

the

recordings

can

be

erased

or

sonically

alterd

to

some

degree.

•

RECORDING

OVER

A

TAPE

WITH

THE

TABS

BROKEN

OUT:

•

Taking

up

tape

slack

If

the

tape

is

used

when

it

is

slack,

or

some

portion

of

the

tape

is

out

of

the

cassette

shell,

there

is

a

risk

it

may

become

tangled

around

the

capstan

or

pinchroller.

In

order

to

correct

this,

insert

a

pencil

or

ballpoint

pen

into

the

center

of

one

reel,

and

rotate

to

take

up

MONITOR

Controls

The

four

MONITOR

controls

determine

the

level

of

the

signal

from

the

corresponding

recorder

tracks

which

is

sent

to

the

PHONES

jack

when

the

PHONES

SELECT

switch

is

set

to

either

“MONi-

TOR”

or

“MIX.”

The

MONITOR

controls

are

primar¬

ily

used

to

set

up

the

optimum

levels

for

monitoring

recorded

tracks

while

recording

new

material

(over¬

dubbing).

®

PHONES

SELECT

Switch

The

MT3X

permits

convenient

headphone

monitor¬

ing

via

a

pair

of

headphones

plugged

into

the

PHONES

jack.

The

de¬

termines

which

are

sent

to

the

PHONES

jack

for

monitoring.

MONITOR:

In

this

position

only

the

output

from

the

recorder’s

four

tracks

is

sent

directly

to

the

PHONES

jack

via

the

four

MONITOR

con¬

trols.

MIX:

Both

the

output

from

the

recorder’s

four

tracks

(via

the

MONITOR

controls)

and

the

stereo

output

from

the

mixer

section

are

Only

the

stereo

output

from

the

mixer

section

is

sent

to

the

PHONES

jack.

®

PHONES

Control

The

PHONES

control

adjusts

both

the

level

of

the

headphone

signal

appearing

at

the

PHONES

jack

and

the

level

of

the

signal

appearing

at

the

rear-

panel

MONITOR

OUT

jacks,

making

it

simple

to

set

the

most

comfortable

level.

®

PHONES

Jack

Any

pair

of

stereo

monitor

headphones

with

an

impedance

of

between

approximately

8

and

40

ohms

can

be

plugged

into

this

jack.

Headphone

monitoring

is

the

most

convenient

way

to

listen

to

the

MT3X’s

various

signals,

and

we

recommend

that

you

obtain

a

pair

of

high-quality

monitoring

headphones

for

this

purpose.

The

YAMAHA

RH-

series

Monitor

Headphones

are

ideal.

®

MASTER

Fader

The

MASTER

fader

sets

the

overall

output

level

of

the

MT3X

mixer

section,

and

thus

the

level

of

the

output

signal

appearing

at

the

ST

OUT

jacks.

The

MASTER

fader

also

affects

recording

level

when

any

of

the

mixer

section’s

channels

are

assigned

to

the

recorder’s

tracks

via

the

PAN

controls

(see

dbx

ON/OFF

Switch

The

dbx

switch

determines

whether

the

MT3X’s

internal

dbx

noise

reduction

system

is

ON

or

OFF.

For

normal

recording

and

playback

using

the

MT3X,

the

dbx

switch

should

be

turned

ON.

This

provides

a

significantly

improved

signal-to-noise

ratio

(as

much

as

85

dB)

so

your

recordings

will

sound

cleaner

and

have

much

less

tape

hiss.

For

dbx

noise

reduction

to

be

effective,

it

must

be

turned

ON

both

during

recording

and

playback.

The

dbx

switch

may

be

turned

OFF

when

playing

back

tapes

that

were

recorded

on

other

equipment

and

which

are

not

dbx-encoded.

TAPE

SPEED

Switch

The

TAPE

SPEED

switch

selects

either

the

stan¬

dard

4.75-cm/sec

cassette

tape

speed,

or

the

MT3X’s

special

9.5-cm/sec

high

tape

speed.

Use

the

standard

(4.75)

speed

when

replaying

tapes

recorded

on

standard

cassette

recorders,

or

to

ob¬

tain

maximum

tape

economy.

When

you

want

maximum

sound

quality,

use

the

high

(9.5)

tape

speed.

The

improvement

in

sound

quality

provided

by

the

high

tape

speed

is

significant,

and

we

rec¬

ommend

that

you

use

the

high

speed

for

all

impor¬

tant

recordings.

®

PITCH

The

PITCH

control

varies

tape

speed

by

±10%,

making

it

to

match

the

pitch

of

musical

instru¬

ments,

or

to

slightly

lengthen

or

shorten

the

running

time

of

a

recording

to

meet

specific

timing

require¬

ments.

Tape

speed

is

normal
