IMPORTANT
NOTICE
When
the
POWER
switch
@
is
set
to
ON,
the
power
relay
does
not
actuate
for
about
7
seconds,
and
no
sound
is
heard
from
the
speakers.
This
silent
duration
is
provided
to
eliminate
“Pop”
sound
which
may
destroy
the
speaker
systems.
After
about
7
seconds,
the
power
relay
is
actuated
with
a
tiny
“click”
sound
and
the
amplifier
is
ready
to
operate.
However,
depending
on
the
sources,
when
this
amplifier
is
operated
at
full
power
continuously
(beyond
200
W)
there
is
a
chance
that
the
sound
may
not
be
heard.
This
means
the
speaker
protection
circuit
works.
In
such
case,
please
reduce
the
Power
output
of
this
amplifier.
Even
if
there
is
no
sound
out
of
the
speaker
system,
the
protection
circuit
for
the
output
transistors
is
working.
Switch
off
the
power
and
rotate
the
volume
.-
control
of
the
control
amplifier
counterclockwise.
Wait
about
30
seconds
before
switching
on
again.
