Please
read
the
PRECAUTIONS
section
of
this
manual
before
setting
up
your
RX21.
The
CONNECTIONS
diagram
which
folds
out
at
the
front
of
this
manual
shows
you
how
to
make
the
simple
connections
necessary
to
set
up
your
RX21.
Use
the
PA-1
power
supply,
or
any
similar
power
supply
to
convert
the
AC
voltage
to
the
voltage
required
to
power
the
RX21
(9
to
12
V).
A
brief
output
pulse
appears
at
the
RX21
outputs
when
the
power
is
initially
turned
on.
To
prevent
this
from
possibly
damaging
your
speaker
system,
make
sure
the
master
volume
control
of
your
sound
system,
or
the
volume
of
the
mixer
channel
to
which
the
RX21
is
connected,
is
set
to
minimum
before
the
RX21
is
turned
on.
Better
yet,
turn
on
the
RX21
first,
then
your
sound
system.
The
RX21
has
an
LCD
(Liquid
Crystal
Display)
panel
that
keeps
you
informed
of
what
is
happening
at
any
moment
(for
example,
which
pattern
is
playing,
or
what
editing
operation
you
are
carrying
out).
When
you
turn
on
the
RX21,
the
LCD
shows
“YAMAHA
RX21”
for
about
a
second,
then
switches
to
the
“SELECT
PTN
00”,
the
basic
select
pattern
mode
display
which
prompts
you
to
select
any
pattern
and
then
play
it
back.
(The
LCD
also
displays
Error
Messages
to
indicate
any
faults
or
operating
errors:
see
the
ERROR
MESSAGES
section
of
this
manual).
Without
any
further
operations,
the
RX21
is
now
ready
for
you
to
play.
