Troubleshooting
No
Sound
Is
it
one
speaker
or
both
speakers?
If
it
is
the
RIGHT
speaker
only,
check
that
the
XD
Speaker
Cable
is
securely
fastened
between
the
LEFT
and
RIGHT
speaker.
In
a
subwoofer
system,
if
both
speakers
do
not
product
audio,
but
the
subwoofer
does,
check
that
there
is
an
audio
connection
from
the
out
of
the
woofer
to
the
input
of
the
speaker
pair.
If
the
subwoofer
is
not
working
and
audio
can
be
heard
from
the
LEFT
and
RIGHT
speaker,
the
audio
input
connections
is
incorrect.
The
audio
input
connection
must
be
made
on
the
subwoofer
first.
If
it
is
both
LEFT
and
RIGHT
speakers,
verify
the
power
switch
is
on
and
the
power
cord
is
used
on
an
active
outlet.
The
Volume
ring
on
the
LEFT
speaker
should
be
illuminated
RED
color
when
the
speaker
system
is
active
with
power.
After
the
power
is
confirmed,
check
that
the
audio
input
cables
are
connected
correctly
and
the
audio
source
is
playing.
Be
sure
the
volume
level
on
the
audio
source
is
not
set
to
MUTE
or
at
minimum
level.
Be
sure
the
volume
knob
on
the
LEFT
speaker
is
not
at
minimum
level
(full
counter
‐
clockwise).
In
quiet
(low
listening
level)
situations,
adjust
the
gain
stages
by
setting
the
volume
to
middle
or
lower
and
increase
the
input
level
of
the
audio
source.
Bad
Sound
Verify
that
all
audio
related
connections
are
securely
attached.
For
example,
make
sure
the
audio
input
connectors
are
clean
and
fully
inserted
into
the
jack.
Check
that
the
wiring
is
not
restricted
and
not
in
close
proximity
to
electrical
interference
sources
such
as
power
cords,
mobile
phones
or
dimming
light.
Distorted
or
noisy
sound
can
result
from
the
source
(computer
or
portable
media
player).
Try
to
listen
to
the
source
using
a
set
of
headphones
and
adjusting
the
volume
to
different
levels.
If
the
audio
is
bad
through
the
headphones,
than
the
source
is
the
problem.
The
position
of
the
speakers
can
contribute
to
bad
sound.
Make
sure
the
proximity
of
the
speakers
is
not
restricted
by
other
objects
such
as
books
or
being
placed
too
close
to
the
wall.
Experiment
by
moving
the
speakers
to
different
positions and
be
sure
the
port
tubes
are
not
obstructed.
The
subwoofer
features
numerous
controls
to
tame
low
frequency
sounds.
First,
be
sure
the
crossover
setting
is
in
the
correct
position
for
the
speakers
being
used.
Smaller
size
speakers
require
the
crossover
to
be
set
at
a
higher
frequency.
Larger
size
speakers
require
the
crossover
to
be
set
at
a
lower
frequency.
The
BYPASS
setting
is
recommended
for
use
with
LFE
or
dedicated
subwoofer
outputs.
The
subwoofer
volume
should
be
set
when
playing
your
most
intense
bass
music
(it
does
not
always
have
to
be
at
max
level).
