VOLTAGE" section.
CAUTION
Never
remove
any
panels,
or open this
equipment.
No user
servicable
parts
inside.
Equipment
power
supply
must
be
grounded
at all
times.
Only use this
product
as described,
in
user
manual
or brochure.
Do
not
operate
this
equipment
in high humidity
or
expose
it
to water
or
other
liquids.
Check the
AC
power
supply
cable to assure
secure contact.
Have
your
equipment checked
yearly
by a
qualified
dealer
service center.
Hazardous
electrical
shock
can be avoided by
carefully
following
the
above
rules.
EXTRA
CAUTION
FOR LI\rE SOUND
Ground
all equipment using
the
ground
pin
in the
AC
power
supply
cable.
Never
remove
this
pin.
Ground
loops
should be
eliminated
only
by
use
of
isolation
transfoffners
for
all
inputs
and
outputs.
Replace any
blown
fuse
with the
same
type and
rating
only
after
equipment
has
been
disconnected
from AC
power.
If
problem
persists,
return
equipment
to
qualified
selvice
technician
PLEASE READ THE
FOLLOWING
INTORMATION
Especially
in
sound
equipment
on
stage
the
following
information is
essential
to
know.
An
electrical shock
is
caused
by voltage and
current, actually
it
is
the current
that
sauses the
shock.
In
practise
the
higher
the
voltage
the
higher
the
current
will be and the
higher the shock.
But
there
is
another thing
to consider
and
it
is
resistance.
When the
resistance
in
Ohms
is
high
between
two
poles,
the
current
will be
low
and
vica
versa.
All
three of these; voltage,
current.
and
resistance
are
important in
determining the
effect
of an electrical
shock.
However,
the
severity of
u shock
prtmurily
determined
by
the
&moant
of current
Ilnring
through
upercon.
A
person
can
feel
a shock
because
the
muscles in
a body
respond
to
electrical current and because
the
heart is
a
muscle
it
can affect, when the
curent
is high
enough.
Current can also be
fatal
when
it causes the chest
muscles
to contract
and
stop breathing.
At what
potential
is
current
dangereous.
Well the
first feeling of current
is
a tingle at
0.001 Amp
of current.
The
current between
0.1
Amp
and
0.2 Amp
is fatal.
Imagine
that
your
home
fuses
of 20 Amp can
handle
200
times
more
current than
is necessaq/
to
kill. How
does
resistance affect
the
shock a
person
feels. A
typical
resistance
between one
hand
to the other
in
udry"
condition could well
over
10Q000
Ohm.
If
you
are
plnying on stage
your
body is
perspiring
&emively
and
your
body resistance
is lowered by more
than 504/o.
This is a situation inwhich
eutrent
can easily
Ilorr,.
Current will
flow
when there
is
a difference
in
ground potential
between equipment on stage
and
in
the
P.A.
system.
Please
do check
ifthere
is any
potential
between
the
housing
of
the mikes
and the
guitarsynth
amps, which will be
linked
by
your
body on stage.
Imagine, a
guitar
in
your
hand
and
your
lips
close
to the mike! A
ground
potential
difference
of above
l0
volts
is not
unusual,
in improperly
wired
buildings
it
can
possibly
be as
high
as24O
volts.
Allthough removing the
ground
wire sometimes
cures a system
hurL
it
will create a very
hazardeous
situation
for
the
performing
musician.
Always
earth all
yoar
equipment by the
grounding pin
in
your
mnins
plug.
Hum
loops should
be only cured
by
propr
wiring and isolation
input/ouQut transformerc.
Replace fuses always
with the same type and
rating after the
equipment
has
been turned off
and unplugged.
Ifthe
fuse blows
again
you
have
an equipment
failure, do
not
use
it
again and return it to
your
dealer
ficr repair.
And
last
but
not
least
be carefull
not
to touch
a
person
being shocked
as
you, yourselfcould
also
be shocked.
Once
removed
from
the shock,
have
someone
send
for
medical
help
inmediately
Aways keq the a.bove
mentionedinfarmdion
in mindwhen using
electrically
powered
equipntent.
