OPERATION
PRECAUTIONS
1.
Speaker
destruction
is
often
due
to
improper
equipment
operation.
This
often
occurs
when
someone
without
the
proper
appreciation
for
the
components
of
a
high
power,
high
quality
music
system,
has
the
opportunity
to change
records
or
adjust
levels.
The
best
protection
here
is caution.
Keep
the
equipment
out
of reach
of
untrained
adults
and
children.
Make
sure the
speaker
is
properly
protected
with
fuses
(Output
Connections
Section).
2.
Never
parallel
the
two
amplifier
outputs
together.
3.
If the
amplifier
continuously
blows
fuses,
something
is wrong
-
do
not
increase
fuse
size.
4.
Do not
connect
an input
ground
lead
to an
output
ground
lead;
to
do
so may
cause
a
ground
loop
and
oscillations.
5.
Do not
operate
the
amplifier
from
power
mains
which
exceed
the
indicated
mains
voltage
by
more
than
10%.
6.
Never
connect
the
output
of the
amplifier
to
another
power
source
such
as a
battery
or
power
main.
7.
Do not
expose
the
amplifier
to
corrosive
chemicals
such
as lye,
soft
drinks,
salt water,
etc.
Also,
never
immerse
the
amplifier
in
any
liquid.
8.
Do not
remove
the
amplifier's
cover
during
operations.
9.
The
amplifier
is
not
intended
for
high
frequency-high
power
use
and
should
not
be
used
for
high
power
at
above
20 kHz.
10.
Neither
the
amplifier
nor any
of
its leads
should
be
exposed
to
areas
likely
to
be
struck by
lightning.
PROCEDURES
After
all
connections
have
been
made
to
the
power
amplifier,
turn
the
gain
controls
fully
counter-clockwise.
Turn
on the
preamplifier,
then
turn
on
the
power
amplifier.
The
LED over
the
circuit
breaker
or
marked
IDLE
should
light.
If
it
does not,
check
to
see that
the
amplifier
is
plugged
in
to
a live
power
outlet.
