of
the
unit.
Additionally,
in
order
to
feel
assured
that
you
have
gained
a
good
grasp
of
every
feature
provided
by
your
new
unit,
this

The
KC-500
keyboard
amplifier
is
specifically
designed
to
accurately
reproduce
the
high-quality
sounds
of
today's
digital
keyboards.
*
The
38-cm
(15-inch)
speaker
and
horn
tweeter
provide
high-power
output
of
sounds
across
the
sonic
spectrum.
*
The
KC-500
offers
four
stereo
pairs
of
input
jacks,
as
well
as
two
stereo
pairs
(1/4"
and
XLRs)
of
line
out
jacks.
*
The
KC-500
provides
a
STEREO
LINK
function.
This
makes
it
possible
to
use
two
KC-
500
amplifiers
to
achieve
full
stereo
output
from
your
keyboard.
*
Input
Channel
4
(CH
4)
includes
a
select
switch
that
lets
you
choose
the
destination
for
output.
This
feature
rounds
out
the
monitor
functions.
*
All
input
and
output
jacks
are
set
at
an
angle,
preventing
connecting
cables
from
becoming
entangled
above
the
control
panel
and
allowing
for
easy
access
to
the
panel.

mended
by
Roland,
the
rack
or

must
be
careful-
ly
placed
so
it
is
level
and
sure
to
remain
stable.
If
not
using

you
still
need
to
make
sure
that
any
location
you
choose
for
placing
the

surface
that
will
properly
support
the

and
keep
it
from

Avoid
damaging
the

Do
not
bend
it
SO
excessively,
step
on
it,
place
heavy
objects
on
it,
etc.
A

with
an
unreasonable
number

or
move
it
farther
away
from
the
source
of
interference.
¢
This

ATTACHING
AND
REMOVING
THE
CASTERS
You
can
attach
or
remove
casters
as
shown
in
the
following
figure.
Be
sure
to
remove
all
casters
when
accidental
move-
ment
may
be
dangerous
such
as
when
setting
up
the
KC-500
on
stage
or
when
transporting
it
in
a
vehicle.
*
Attaching
all
of
the
casters
can
make
it
easier
to
move
the
amplifier.
¢
You
can
use
the
KC-500
as
a
floor
monitor
by
removing
the
two
wheels
on
the
rear-panel
side
and
setting
the
amplifier
at
an
angle.
(Be
sure
it
remains
stable
when
you
do
so.)
Once
the
connections
have
been
completed,
turn
on
power
to
your
various
devices
in
the
order
specified.
By
turning
on
devices
in
the
wrong
order,
you
risk
causing
malfunction
and/or
damage
to
speakers
and
other
devices.
1.
Make
sure
that
all
volume
controls
on
the
KC-300
and
con-
nected
devices
are
set
to
0.
2.
Turn
on
the
keyboard(s)
and
sequencer
(if
you're
using
one).
3.

the
KC-300.
4.
If
a
mixer
is
connected
to
the
LINE
OUT
jack(s)
on
the
KC-
300,
turn
on
the
mixer.
5.
Adjust
the
volume
levels
for
the
devices.
Stereo
Link
If
two
KC-300
units
are
used,
you
can
easily
make
connections
for
stereo
output.
This
function
is
called
"Stereo
Link.”
The
right-channel
signals
are
output
from
the
speakers
in
the
main
unit,
while
the
left-channel
signals
are
output
from
the
speak-
ers
in
the
sub
unit
(the
other
KC-300).

This
can
be
remedied
by:
1.
Changing

sub
amplifier,
you
can
use

stand.
If
a
speaker
stand
is
used,
the
KC-300
can
be
placed
at
a
height
ideal
for
monitoring,
and
can
also
be
used
as
a
simple
PA
system.
If
two
KC-300
units
are
placed
on
speaker
stands
and
used
with
Stereo
Link,
they
can
function
as
a
simple
100
