CONNECTING
THE
AMPLIFIER
TO
YOUR
SYSTEM
Refer to Figure 1-6 (fold-out
from
Page
43)
before
you
connect the speaker
system
and
accessory equipment to your
Amplifier.
SPEAKER PLACEMENT
Generally,
for
stereo
listening,
the
two
speakers should
be
spaced four to
eight
feet
apart.
They
should
be
placed along
a wall facing the
listening
area.
The
optimum
positions
can
best
be
determined
by
experiment. A
great
deal depends
upon
the
size
and
acoustic
properties
of
the
room,
and
upon
the high frequency
dispersion
characteristics
of
the
speakers. Identi
ea
l speakers or
speaker systems are
recommended
for
stereo operation.
Correct spacing
between
speakers depends,
to
some
extent,
upon
the
listener's
position
and
distance
from
the speakers.
If
the
listening
position
is
restricted
to
-0ne
that
is
relatively
close to the
speakers,
some
improvement
may
be
obtained
by
moving
the speakers
closer
together.
Stereophonic reproduction
is
striving
to
recreate
as
accurately
as
possible
not only the sounds
of
"right"
and
"left"
origin,
but also those near the
centre. Experiment with speaker
and
listening
positions to
arrive
at
the
best
set
of
conditions for your
particular
installation.
SPEAKER CONNECTIONS
Each
channel of your Amplifier
has
two
output terminals: R (Right channel) or
L (Left channel)
and
C
(common).
In
the
following
steps,
your speaker system
for
each channel
will
be
connected to
the R or
Land
C terminals.
Any
speaker
system
can
be
connected to the Amplifier's
output terminals; however,
optimum
performance will
be
obtained with
speakers
of
4 to
16
ohms
impedance. For
best
sound
balance,
use
speakers
of
the
same
impedance
for both the
right
and
1
eft
channels.
Spflaker
Terminal Identification
Speaker terminals
are
usually
labelled
to
identify
one
terminal
from
the
other.
This
may
be
by
number, colour,
minus
(-)
and
plus
(+),
or
some
other
designation.
It
makes
little
difference
how
your
speaker terminals
are
designated,
just
so
you
can
distinguish
one
terminal
from
the
other.
If
your speakers
are
labelled,
fol
low
the steps under "Labelled Speakers."
If
your speakers are not
labelled,
follow
the
instructions
under "Speaker Phasing."

( ) Connect a wire to the
marked
terminal
on
your
left
speaker. Connect the
other
end
of
this
wire to the
Amplifier terminal C
that
is
nearest
to the
PHONO
input sockets.
( ) Connect a wire
from
the other
terminal
on
your
left
speaker to
terminal
Lon
the Amplifier.
( )
In
the
same
manner, connect a wire
to the
marked
terminal
on
your
right
speaker. Connect the
other
end
of
this
wire to the other
(right
speaker)
terminal Con the Amplifier.
( ) Connect a wire
from
the
other
terminal
on
your
right
speaker to
terminal Ron the Amplifier.
