other
amplifiers
of
the sound system.
It
h
as
to
be
c
onnected
to
the
REMOTE
IN
of
successive
amplifiers
to
allow
the
simultaneous

IN
Input
control
coming

It
is
especially
made
to
be
connected
to
the

in
order
to
silence
the

It
can
be
connected
to
the
MUTE

output
of
a

to
allow
the
simultaneous
silencing
of
all

connected
in

must
be
between
3

MUTE
OUT
Output
for

other
amplifiers
in
the
reproduction
system.
It
must
be
connected
to
the
MUTE
IN
of
the
