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.

Stacking
Examples
Connecting
two
or
more
mixers
to
increase
the
total
number
of
channels
is
called
“stacking”.
You
can
“stack”
the
M-240R
with
another
M-series
mixer
for
even
greater
mixing
capabilities.
For
example,
by
connecting
the
M-240R
to
an
M-12E,
you
can
mix
the
signals
from
microphones
and
guitars
with
those
from
electronic
musical
instruments.
