2.1
UNPACKING

INSPECTION
Your
JBL
Power
Amplifier
was
carefully
packed
at
the
factory,
and
the
container
was
designed
to
protect
the

from
rough
handling.
Nevertheless,
we
recommend
careful
examination
of
the
shipping
carton
and
Its
contents
for
any
sign
of
physical
damage
which
could
have
occurred
In
transit.
If
damage
is
evident,
do
not
destroy
any
of
the
packing
material
or
the
carton,
and
Immediately
notify
the
carrier
of
a
possible
claim
for
damage.
Shipping
claims
must by
made
by
the
customer.
Save
the
carton
and
packing
material
In
the
event
the

must
be
returned
for
service.
See
Section
5.2,
’’Repairs

for

on

2.2
ENVIRONMENTAL
CONSIDERATIONS
The
amplifier
will
operate
satisfactorily
over
a
range
of
ambient
temperatures
from
0“C
to +50*C
(+32*F
to
122*F),
and
up
to
80$
non-condensing
relative
humidity.
If
the
amplifier
Is
Installed
in an
equipment
rack,
adequate
ventilation
must
be
provided
In
order
to
assure
longest
component
life.
Additional
heat-producing
devices
should
not
be
placed
directly
above or
below
the
amplifier,
but
at
least
1-3/4”
away.
Keep
any
obstructions
such as
wire
bundles
and rear
mounted
connector
panels
away
from
fan
Intake
area.
Again,
do
not
mount
other
products
above
or
below
the
amplifier
In
such a
way
that
would
block
off
air
flow
to
heatsink
area.
It
is
normal
for
the
amplifier
front
panel
and
rack
ears
to
become
warm
during
operation
since
it
Is
part
of
the
heatsinking
system
of
the
amplifier.
See
Section
3.2.1,
a
note
on
amplifier
cooling.
Since
the
amplifier
is
quite
heavy,
be
sure
the
rack
is
capable
of
supporting
it.
When
a
rack is
to
be
transported
with a
portable
sound
system,
the
amplifier
should
be
supported
from
the rear
and
from
below;
a
few
pieces
of
angle
Iron
secured
to
the
sides
of
the
rack
should
suffice.
It
is
also
recommended
that
the
amplifier
be
placed
low
in
the
rack
to
minimize
any
tendency
for
the
rack
to
tip
over.
2.3

any
other

identified
as

power
cord.
