PROTECTOR
CIRCUIT
Even
if
the power switch
of the
QM-800
is turned on,
the
speaker system
will not
operate
for
the
first
5
to
8
seconds.
This is
because
the QM-800 is provided
with
a
circuit
which
protects transistor,
speakers,
etc. from
possible damage due
mainly
to
unexpected trouble.
If
any
of
the
speaker systems stops
operating during a
per-
formance,
or
if
mechanical noise
(click, click,
. .
.) of
the
relays
is
heard continuously, a short-circuit
in
the
speaker
leads
may be responsible.
Turn
off
the power and
check
all
speaker
connections.
Since
the
protector circuit is
very
sensitive,
it
may be activated
if
the
power switch
of
the
preamplifier combined
with the
QM-800
is turned on
and
off
separately.
It
is therefore advisable
to
obtain AC
power
for
the
QM-800
from a
switchable
AC outlet of
the
pre-
amplifier,
as
this
guarantees
simultaneous
on-off
switching
of both
units.
