FEATURES

Roland

M-240R.

The

M-240R

is

a

compact

yet

versatile,

high-quality

24

channel

unit,

please

read

this

manual

carefully.

The

M-240R

is

a

4U

rack-mountable,

24

channel

mixer

specifically

designed

for

line

input

sources.

There

is

independent

control

over

each

signal's

input

level

(-30dBm

to

+4dBm)

and

stereo

positioning

(panning).

The

M-240R

features

4

independent

SEND

OUT

jacks

and

6

Stereo

RETURN

jacks.

What's

more,

the

output

of

1

of

the

4

SEND

OUT

jacks

can

be

switched

to

pre-

fader

or

post-fader.

These

jacks

can

be

used

for

monitoring

applications

or

with

various

effect

devices.

In

order

to

maintain

the

signal

integrity

and low

noise

output

common

to

all

M-

series

mixers,

the

M-240R

has

been

designed

to

meet

exacting

standards.

Two

independent

outputs

(MASTER

OUT

and

SUB

OUT)

are

provided.

Each

channel’s

output

can

be

sent

to

either

or

both

of

these

outputs

using

the

Output

Select

Switch.

Moreover,

the

MASTER

OUT

includes

a

Mute

Switch

and

Mute

Indicator

which

enhance

the

M-240R’‘s

flexibility.

As

well

as

the

MASTER

and

SUB

controls,

a

MONITOR

control

is

also

provided.

This

allows

independent

volume

control

of

the

MASTER

OUT

signal

or

the

SUB

OUT

signal

through

the

MONITOR

OUT

jacks.

These

signals

can

also

be

heard

through

headphones.

The

MONITOR

BUS

INPUT

allows

you

to

hear

the

tempo

"click"

from

a

sequencer

through

the

MONITOR

OUT

jacks

or

the

Headphone

jack.

The

BUS

INPUT

contains

the

Send

jacks

(AUX,

EFF1-3)

which

permit

“full-function”

stacking

of

M

Series

mixers.

The

M-240R’s

MASTER

OUT

XLR

connectors

(balanced

output)

allow

the

unit

to

function

in

professional

environments.

A

Peak/Signal

(PEAK/SIG)

Indicator

is

provided

for

each

channel

and

a

5-segment

Peak

Meter

is

provided

in

the

MASTER/SUB

section.

These

indicators

assist

in

setting

accurate

signal

levels.

In

addition,

you

can

monitor

the

pre-fader

signal

level

of

the

MASTER

OUT

(with

the

MONITOR

Peak

Meter)

by

pressing

the

MONITOR

SELECT

switch.

Notes

[Power

Supply]

[Placement]

[Maintenance]

In

addition

to

the

items

listed

under

Safety

Precautions

on

page

2,

please

read

and

adhere

to

the

following:

e

When

making

any

connections

with

other

devices,

always

turn

off

the

power

to

all

equipment

first;

this

will

help

prevent

damage

or

malfunction.

e

Do

not

use

this

unit

on

the

same

power

circuit

with

any

device

that

will

generate

line

noise,

such

as

a

motor

or

variable

lighting

system.

e

Avoid

damaging

the

power

cord;

do

not

step

on

it,

place

heavy

objects

on

it

etc.

*

Do

not

subject

the

unit

to

temperature

extremes

(eg.

direct

sunlight

in

an

enclosed

vehicle).

Avoid

using

or

storing

the

unit

in

dusty

or

humid

areas

or

areas

that

are

subject

to

high

vibration

levels.

e

Using

the

unit

near

power

amplifiers

(or

other

equipment

containing

large

transformers)

may

induce

hum.

e

This

unit

may

interfere

with

radio

and

television

reception.

Do

not

use

this

unit

in

the

vicinity

of

such

receivers.

e

Do

not

expose

this

unit

to

temperature

extremes

(eg.

direct

sunlight

in

an

enclosed

vehicle

can

deform

or

discolor

the

unit)

or

install

it

near

devices

that

radiate

heat.

e

For

everyday

cleaning

wipe

the

unit

with

a

soft,

dry

cloth

(or

one

that

has

been

slightly

dampened

with

water).

To

remove

stubborn

dirt,

use

a

mild

neutral

detergent.

Afterwards,

be

sure

to

wipe

the

unit

thoroughly

with

a

soft,

dry

cloth.

*

Never

use

benzene,

thinners,

alcohol

or

solvents

of

any

kind,

to

avoid

the

risk

of

discoloration

and/or

deformation.

[Additional

Precautions]

Protect

the

unit

from

strong

impact.

Do

not

allow

objects

or

liquids

of

any

kind

to

penetrate

the

unit.

In

the

event

of

such

an

occurrence,

discontinue

use

immediately.

Contact

qualified

service

personnel

as

soon

as

possible.

Never

strike

or

apply

strong

pressure

to

the

signal

level

indicators.

A

small

amount

of

heat

will

radiate

from

the

unit,

and

thus

should

be

considered

normal.

Before

using

the

unit

in

a

foreign

country,

consult

with

qualified

service

personnel.

Should

a

malfunction

occur

(or

if

you

suspect

there

is

a

problem)

discontinue

use

immediately.

Contact

qualified

service

personnel

as

soon

as

possible.
