Congratulations!

Your

MR-series

mixing

console

offers

the

quality

that

has

made

YAMAHA

a

leading

name

in

console

design,

plus

a

wealth

of

features

and

versatile

signal

routing

capability

that

makes

it

ideal

for

a

wide

range

of

applications.

The

MR842,

MR1242

and

MR1642

offer

8,

12

and

16

input

channels,

respectively.

The

input

channels

can

be

assigned

to

any

of

four

group

busses,

and

the

group

busses,

in

turn,

can

be

assigned

to

a

master

stereo

buss.

This

combination

of

group

and

stereo

busses

makes

the

MR-series

consoles

ideal

for

use

in

recording

and

sound

production

applications

as

well

as

small

sound

reinforcement

Jobs.

The

channel

inputs

are

all

electronically

balanced,

but

will

also

accept

unbalanced

signals

—

both

XLR

and

TRS

phone

|

jack

connectors

are

provided

for

each

input.

The

input

channels

feature

mic/line

or

tape

input

selection,

a

20

dB

input

pad

and

input

gain

control

that

permit

precise

level

matching

with

all

types

of

input

source.

Each

channel

also

offers

a

three-band

equalizer

with

shelving

low

and

high

bands,

and

a

sweepable

peaking

mid

frequency

band.

An

insert

patch

point

is

provided

immediately

prior

to

the

EQ

stage.

Three

auxiliary

send

controls

on

each

input

module

provide

a

range

of

submixes

for

effects,

monitoring

or

other

applications.

A

selector

assigns

AUX

3

send

to

the

pre-EQ

channel

signal

or

the

channel’s

tape

input.

Group

assign

switches

assign

the

channel

signal

to

groups

1

and

2

and/or

3

and

4,

with

panning

capability

between

groups.

The

four

group

modules

include

the

three

master

AUX

send

controls

and

dual

AUX

return

level

controls

with

assignment

switches

for

the

four

groups

and

the

master

stereo

buss.

Each

group

module

also

has

a

pan

control

that

pans

the

signal

from

that

group

across

the

stereo

buss.

The

L

and

R

channel

stereo

modules

include

the

monitor

assign

switches

and

talkback

facilities.

All

group

and

stereo

outputs

offer

both

electronically

balanced

+4

dB

outputs

and

standard

-10

dB

RCA

jack

outputs

for

compatibility

with

the

broadest

possible

range

of

equipment.

In

order

to

make

the

most

of

your

MR-series

mixing

console

and

all

the

features

and

versatil-

ity

it

offers,

we

urge

you

to

read

this

operation

manual

thoroughly

—

and

keep

it

in

a

safe

place

for

later

reference.

care.

7.

ALWAYS

USE

THE

CORRECT

POWER

SUPPLY

Make

sure

that

the

power

supply

voltage

specified

on

the

rear

panel

matches

your

local

AC

mains

supply.

3.

DO

NOT

OPEN

THE

CASE

OR

ATTEMPT-REPAIRS

OR

MODIFICATIONS

YOURSELF

This

product

contains

no

user-serviceable

parts.

Refer

all

maintenance

to

qualified

MAKING

OR

REMOVING

CONNECTIONS

~

Always

turn

the

power

OFF

prior

to

connecting

or

dis-

`

connecting

MID

FREQ

@

TAPE

Switch

The

TAPE

switch

provided

at

the

top

of

each

input

channel

module

determines

whether

the

input

signal

to

that

module

is

received

via

the

corresponding

rear-

panel

LO-Z

or

HI-Z

input

connector

or

the

TAPE

input

jack.

When

this

switch

isin

the

JL

(upper)

position,

the

channel’s

LO-Z

and

HI-Z

inputs

are

active,

and

when

itisinthe

„mm.

(lower)

position

the

TAPE

input

jack

is

selected.

Normally,

the

rear-panel

TAPE

inputs

will

be

connected

to

the

outputs

of

a

multitrack

tape

recorder.

The

TAPE

switches

therefore

allow

conven-

ient

routing

of

the

recorder

outputs

to

the

console's

input

channels

for

mixdown.

PAD

Switch

This

switch

attenuates

the

signal

applied

to

the

corre-

sponding

rear-panel

HI-Z

or

LO-Z

input

by

20

dB

prior

to

the

head

amplifier

and

input

gain

control.

The

PAD

switch

effectively

increases

the

range

of

input

signal

levels

that

can

be

handled

by

the

mixer,

preventing

overloading

of

the

input

circuitry

when

receiving

high-

level

signals.

The

pad

is

ON

when

the

PAD

switch

is

in

the

ma

(lower)

position.

GAIN

Control

This

control

adjusts

the

input

sensitivity

of

each

input

channel

between

-60

dB

(0.775

mV)

and

-20

dB

(77.5

mV)

when

the

PAD

switch

is

OFF

(between

—40

dB

and

0

dB

when

the

PAD

switch

is

ON).

Continuously

variable

gain

control

allows

optimum

matching

with

virtually

any

microphone

or

line

source.

CLIP

LED

Indicator

The

CLIP

indicator

LED

lights

when

the

post-EQ

signal

of

the

corresponding

channel's

input

reaches

a

level

3

dB

below

the

clipping

level

of

the

channel's

circuitry.

If

the

CLIP

indicator

lights

more

than

only

briefly

on

high-

level

transients

it

is

necessary

to

decrease

the

input

sensitivity

of

the

channel

using

the

GAIN

control

and

PAD

switch

or,

if

this

does

not

provide

sufficient

attenuation,

to

reduce

the

output

level

of

the

source

connected

to

that

channel's

input.

The

_

NOTE:

Internal
