Rear panel connections
(See pages 113, 114, 115.)
All
connections
to
the
rear
panel
should
be
made
with

the
system.
To
avoid
miss-connection,
it
is
advisable
to
connect
one
cable
at
a
time
between
the
different
components.
This
is
the
safest
way
to
avoid
cross-connecting
channels
or
mix-up
signal
inputs
with
outputs.

Note on joudspeaker impedance:
The
power
ratings
specified
for
this
Marantz
receiver
are
obtained
using
fixed
value
test
load
impedances.
However,
the
actual
impedance
of
a
loudspeaker
system
will
vary
with
frequency,
deviating
from
the
nominal
rating.
This
Marantz
amplifier
will
drive
any
modern
loudspeaker
system
with
a
rated
impedance
of
4
ohms
or
higher.
A
few
newer
loudspeakers
feature
impedances
of
less
than
4
ohms.
The
high
current
output
capability
of
this
Marantz
receiver
can
provide
the
additional
power
necessary
to
drive
such
low
impedance
speakers.
However,
during
extended
passages
of
high
volume,
the
protection
circuitry
may
temporarily
interrupt
opera-
tion.
If
this
occurs,
simply
reduce
the
volume
accordingly.
The
protection
circuitry
is
specially
designed
so
that
it
cannot
affect
the
sound
quality
during
normal
operation.
