Chqnnel
In large
tooms,
where
it
may
be necessary
to
space
loudspeakers
farther apart
to
cover a
wider area,
a'ohole"
may
develop
in the
center'
This
apparent
lack
of sound
in
the center
will
become
more
noticeable
as
the distance
between
the two speakers
is
increased.
It
is
possible to
fill in
this
gap
with
the addition
o{ a
center
channel
amplifier
and
loudspeaker.
Th;
X-100 is
equipped
with a
Center
Channel
output
jack
which
is
connected
to a divider
network across
the output stages
of Channel
A
and
B.
Equal
portions
of the
audio
output signal
from
each
channel
are
thus combined
to form a center
"phantom"
channel'
By connecting
an additional
amplifier
and loudspeaker
to
this output
jack,
and
posi
tioning
the speaker
between
the
left and
right
speakers,
the stereo"
phonic pattern o{
sound
will
be augmented.
The
third amplifier
need
not be
equipped
with tone
controls'
since
these are
provided
hy
the
X'100, A volume
control,
or input
level
con-
trol,
will
be
helpful,
however, in
order that
the volume
of
the center
speaker
may be adjusted
to the necessary
level. Connect
a short
length
oI
shielded
cable,
of the low-capacitance
type,
{rom
the CENTER
CHANNEL
output
jack
on the
rear
panel
o{
the
X'100
to
an
input
o{ the center
channel amplifier.
The
length
of cable from
the amplifier
to
the
center
speaker can be
considerably
longer
(up
to
100 feet,
or
more) depending
on
the type
of amplifier
used.
The center speaker
can also be
used in an adjoining
room
or
some
other remote
location. Although
the output
from this extension
speaker
will be
monophonic,
it
will
contain
the composite stereo
signal.
