Troubleshooting
No
Power
Is
it
plugged
in?
Make
sure
the
power
cord
is
securely
seated
in
the
IEC
socket
and
plugged
all
the
way
into
the
AC
outlet.
Is
anything
on
the
front
panel
illuminated?
If
not,
make
sure
the
AC
outlet
is
live
[check
with
a
tester
or
lamp].
Make
sure
the
rear
panel
power
switch
is
in
the
ON
position.
Are
all
the
lights
out
in
your
local
area?
If
so,
contact
the
local
power
company
to
get
power
restored.
Is
the
fuse
blown?
See
the
following
instructions
for
removing
and
replacing
it.
If
nothing
is
illuminated
(and
you
are
certain
that
the
AC
outlet
is
live
and
the
fuse
is
not
blown),
it
will
be
necessary
to
have
the
DX0.5
serviced.
There
are
no
user
serviceable
parts.

to
Repair
on

Noise
/
Hum
Try
changing
the
position
of
the
main
ground
lift
switch
[3]
on
the
rear
panel
of
the
DX0.5.
Check
the
signal
cables
between
the
mixer
and
the
processor
and
the
processor,
amps
and
loudspeakers.
Disconnect
them
one
‐
by
‐
one.
If
the
noise
goes
away,
you
will
know
which
input
or
output
is
causing
the
problem.
It
often
helps
to
plug
all
the
audio
equipment
into
the
same
AC
circuit
so
they
share
a
common
ground.
To
remove
and
replace
the
fuse:
1.
Disconnect
the
power
cord
from
the
IEC
socket.
2.
Remove
the
fuse
drawer
by
prying
it
open
with
a
small
screwdriver.
It
will
slide
all
the
way
out.
3.
Remove
the
fuse
and
replace
it
with
an
equivalent
‐
type
fuse:
T
800mAL
/
250
V
4.
Replace
the
fuse
drawer
by
pushing
it
all
the
way
back
into
the
IEC
socket.
If
two
fuses
blow
in
a
row,
there
is
a
more
serious
problem.
Try
a
different
outlet
in
a
totally
different
location.
If
fuses
continue
to
blow,
see
the
Repair
section
on
the
next
page
to
find
out
what
to
do.
No
Sound
Are
the
level
controls
on
the
mixer
or
amplifier
turned
all
the
way
down?
Follow
the
procedures
in
“Getting
Started”
section
on
page
5
to
verify
that
all
of
the
volume
controls
in
the
system
are
properly
adjusted.
Is
the
signal
source
working?
Are
all
the
connections
good
and
sound?
Make
sure
all
of
the
connecting
cables
are
in
good
repair
and
securely
connected
at
both
ends.
One
side
is
louder
than
the
other
