Precautions
The
STR-GX49ES
is
a
receiver
which
controls
audio/video
sources.
The
unit
allows
you
to
switch
easily
among
a
variety
of
audio/video
programs.
Amplifier
•
Optical
Legato
Linear
A
System
allows
the
receiver
to
operate
automatically
as
a
class
A
amplifier
when
the
level
is
low
and
as
a
class
B
amplifier
when
the
level
is
high
without
disturbing
the
sound
signal.
This
minimizes
total
harmonic
distortion
at
every
sound
stage.
•
These
receivers
have
a
spontaneous
twin
drive
power
circuit.
Condensers
having
large
capacity
are
used
independently
for
the
voltage
amplification
drive
stage
of
class
A
and
power
output
stage
of
class
B.
Thus,
a
stable
output
and
high
quality
sound
are
obtained,
resulting
in
exclusion
of
power
interferences.
The
class
A
stage
realizes
a
stable
operation
free
from
interference
of
the
power
stage
even
when
an
instantaneous
or
strong
output
is
received.
•
A

is
employed
to
reproduce

sound.
Any
source
can
be
reproduced
without
passing
through
the
circuits
of
tone
control,
loudness
switch
and
balance
control.
Tuner
•
Precise
tuning
is
obtained
thanks
to
the
quartz-locked
digital
synthesizer
system.
•
A
total
of
30
FM/AM
stations
can
be
preset
in
3
memory
pages
(A,

that
allow
you
to

Remote
commander
•
The
remote
commander
allows
you
to
control
most
of
Sony’s
audio
equipment
from
a
distance.
On
safety
•
Operate
the
unit
only
on
120
V
AC,
60
Hz.
•
Should
any
solid
object
or
liquid
fall
into
the
cabinet,
unplug
the
unit
and
have
it
checked
by
qualified
personnel
before
operating
it
any
further.
•
Unplug
the
unit
from
the
wall
outlet
if
it
is
not
to
be
used
for
an
extended
period
of
time.
To
disconnect
the
cord,
pull
it
out
by
grasping
the
plug.
Never
pull
the
cord
itself.
•
One
blade
of
the
plug
is
wider
than
the
other
for
the
purpose
of
safety
and
will
fit
into
the
power
outlet
only
one
way.
If
you
are
unable
to
insert
the
plug
fully
into
the
outlet,
contact
your
dealer.
On
operation
•
Before
making
program
source
connections,
be
sure
to
turn
the
power
switch
off
and
unplug
the
unit.
m
When
the
unit
is
not
used,
turn
the
power
off,
to
conserve
energy
and
to
extend
the
useful
life
of
your
unit.
On
cleaning
the
cabinet
Clean
the
cabinet,
panel
and
controls
with
a
soft
cloth
lightly
moistened
with
mild
detergent
solution.
Do
not
use
