OPERATION
The
MC
7300
also
can
be
used
as
a
single
channel
monophonic
power
amplifier
in
parallel
configura-
tion.
The

output
taps
are
now
connected
in
parallel
and
the
impedances
will
be
exactly
half
what
is stated
at the terminals.
Connect
a
cable
from
the

minal
to
either
the
LEFT
OUTPUT
LC
terminal
or
the
RIGHT
OUTPUT
RC
terminal.
(These
terminals
are
wired
together
inside
the
amplifier.)
Connect
the
cable
from
the
hot
speaker
terminal
to
the
im-
pedance
output
desired
on
either
channel.
Also
wire
across
to
the
other

tap.
In
each
case,
the
chosen
outputs
of
each
channel
must
be wired
together.

HOW TO CONNECT AC POWER
The MC 7300 is designed to operate on 120 volts
50/60
Hz.
Plug
the
AC
power
cord
directly
into
a
wall
outlet.
Make
certain
that
the
AC
power
outlet
has
at
least
12
amperes
capacity
available.
If
you
choose
to
connect
the
amplifier
AC
power
to
the
back
AC
í
outlet
on
a
preamplifier
or
other
accessory,
make
certain
it
can
supply
12
amperes
of
current.
The MC 7300 can draw up to 12 amperes of cur-
rent
from
the
AC
power
line
when
both
channels
are
producing
rated
power
output.
The
amplifier
uses
only 0.6 amperes of current when idling at no
output.
The
AC
auxiliary
outlet
on
the
amplifier
rear
panel
will provide
up to 100 watts
(1 ampere),
and is not
fused
or
switched.
FUSE
A 15 ampere fuse protects the MC 7300 circuits.
The
fuse
does
not
protect
additional
equipment
con-
nected to the rear panel, auxiliary AC outlet.
