JBL 6260 User Manual

Furthermore,
remember
that
the
amplifier
is
heavy.
The
rack,
especially
its
mounting
rails,
should
be
capable
of supp-
orting
the
amplifier.
When
a
rack is
to
be
transported
with
a
portable
sound
system,
the
amplifier
also
should
be
supported
from
below; a
few pieces
of
angle
iron
secured
to
the
sides
of
the rack
will
suffice.
It
is
further
recommended
that
the
amp-
lifier be
placed
low
in the
rack
to keep
the center
of
gravity
low and
thus
avoid any
tendency
for
the rack
to
tip
over.
