INSPECTION AND INSTALLATION
2.1
UNPACKING
AND INSPECTION
Your JBL Power Amplifier was carefully packed
at
the factory,
and
the
container
was designed to protect the unit 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 unit must
be
returned
for
service.
See
Section
5.2,
''Repairs and
Warranty,"
for
Instructions
on
returning
a
unit.
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
AC
POWER
All
JBL Power
Amplifiers shipped
to
points
in
the USA
and
Canada are wired
for
120
VAC 60 Hz
operation.
Amplifiers wired
for
operation
on any
other voltage are identified
as
such with
a
sticker
on
the rear panel
and
a
tag attached to the
amplifier power
cord.
