McIntosh MC 7300 User Manual

CONNECTING
CABLES
Use
shielded
cables
to
connect
the
signal
from
the
preamplifier
or
other
signal
source
to
the
power
amplifier.
To
minimize
the
possibility
of
hum,
the
cables
should
be
located
away
from
speaker
connect-
ing
cables
and
AC
power
cords.
Use
good
quality
cables.
Your
dealer
can
advise
you
on
the
type
and
lengths
of
cables
that
will
best
suit
your
installation.
STEREO
OPERATION
(UNBALANCED
INPUTS)
Use
shielded
single
conductor
cable
with
RCA
type
plugs.
Connect
the
cable
from
the
left
channel
out-
put
of
a
preamplifier
to
the
LEFT
UNBALANCED
IN-
PUT
on
the
power
amplifier.
Connect
the
right
chan-
nel
output
to
the
RIGHT/MONO
UNBALANCED
INPUT.
Set
the
MODE
switch
to
STEREO.
STEREO
OPERATION
(BALANCED
INPUT)
Modern
technology
has
made
it
possible
to
build
preamplifiers
and
power
amplifiers
with
the
high
signal
to
noise
ratio
necessary
to
reproduce
the
sound
quality
present
on
compact
discs
or
any
other
wide
dynamic
range
signal
source.
It
is
possible
for
conventional
interconnecting
cables
to
pick
up
electrical
interference
from
other
equipment,
AC
cables
or
electrical
appliances.
Using
the
balanced
inputs
provides
an
additional
40dB
more
protection
against
such
noise
pickup.
Use
2
conductor
shielded
cables
with
XLR
type
connectors
to
connect
between
the
preamplifier
and
the
power
amplifier.
The
maximum
effect
of
balanc-
ed
cables
is
realized
when
both
the
preamplifier
and
power
amplifier
have
similar
XLR
balanced
connectors.
Connect
the
left
balanced
output
cable
from
a
preamplifier
to
the
LEFT
BALANCED
INPUT
on
the
power
amplifier.
Connect
the
right
output
to
the
RIGHT
BALANCED
INPUT.
Pin
configuration
for
the
XLR
INPUT
connectors
on
the
MC
7300.
PIN 1: Shield or ground.
PIN 2: + output.
PIN 3: - output.
In
stereo
installations
where
the
amplifier
and
preamplifier
are
close
to
each
other
and
require
in-
terconnecting
cables
of
six
feet
or
less,
using
quality
unbalanced
connecting
cables
is
usually
perfectly
satisfactory.
If
the
units
are
farther
apart
and
require
longer
interconnecting
cables,
using
balanced
cables:
-
will
give
extra
protection
from
noise
or
interference.
MONOPHONIC
BRIDGE
OR
PARALLEL
A
rear
panel
MODE
switch
allows
the
amplifier
to
be
used
in
normal
STEREO,
MONO
(BRIDGE)
or
MONO
(PARALLEL).
When
switched
to
either
MONO
(BRIDGE),
or MONO
(PARALLEL)
operation,
the
RIGHT
BALANCED
and
UNBALANCED
inputs
are
the
only
ones
used
for
the
mono
input
signal.
The
LEFT
inputs
are
automatically
disconnected.
Connect
the
appropriate
cable
from
a
preamplifier
or
other
mono
source
to
the
appropriate
RIGHT
UNBALANCED
or
BALANCED
amplifier
input.
