addition
to
the
low-pass crossover
in
your decoder,
simply
plug
the
sub
or
LFE
output of your decoder
into
the
left
or right low-level
input
ofyour SuperCube
subwoofer.
However,
in
almost
all
cases, a dedicated
LFE
output already
has
its
program material tailored
for
input into
an
unfiltered
LFE
input
and
as
such
should
be
fed
into
the
LFE
input
on
your SuperCube.
Alternately, another
way
to
hook
up
your Definitive
Technology
SuperCube
subwoofer
is
via
the
low-level input connectors
which
are
gold-plated RCA-type
jacks designed
to
accept standard audio interconnect cables. For preamps
and
decoders,
run
an
interconnect
from
the
left
and
right outputs of
the
preamp
or
decoder
to
the
left
and
right low-level inputs
on
the
subwoofer.
If
you
have
two
sets
ofoutputs,
you
can
use
one
set
of
these;
if
not,
you
can
put
a Y-connector
into
each output (left
and
right)
and
run
half of each Y
back
into
a (left
and
right)
main
input
on
the
preamp
decoder,
receiver
or
power
amp
and
the
other half
into
the
(left
and
right) low-level input
on
the
subwoofer.
High-Level Speaker
Wire
Connections
Your
Definitive
Technology
SuperCube subwoofer
can
also
be
hooked
up
via
high level connections.
In
this
situation,
you
have
the
option
of running
your
main
speakers "full range"
or
rolling off
the
low
end
by
using
the
high-pass
filter
built
into
the
subwoofer.
For high-level wiring, your interconnects
are
simply
equal
distance lengths of
high
quality speaker cable.
To
hook
up
your SuperCube
sub
woofer
via
the
high-level connections,
simply
run
speaker cable
from
the
right
channel high-level connector
on
the
subwoofer
to
the
right channel speaker connector ofyour receiver
or
amplifier.
Repeat
this
process
for
the
left channel. Please
take
care that
the
red
(+) terminal
on
the
subwoofer
is
connected
to
the
red
(+) terminal
on
your receiver
or
amplifier,
and
that
the
black
(-)
terminal
on
your
receiver
or
amplifier
is
connected
to
the
black
(-)
terminal
on
the
subwoofer.
This
will
ensure absolute phase throughout
your
system.
Your
main
speakers
can
now
be
connected
in
one
of
two
ways.
If
you
wish
to
utilize
the
high-pass
filter
built
into
your subwoofer,
simply
connect your
main
speakers
to
the
high-level
out
terminals
on
the
subwoofer.
[See
Diagram

Again, take care
to
make
red
to
red
(+)
and
black
to
black
(-
) terminal connec-
tions. This connection
will
provide a smoothly contoured roll-off of
the
low
fre-
quencies going
to
your
main
speakers starting
at
80
Hz.
For
more
overall
bass
out-
put
when
using
full-range
main
speakers,
run
the
main
speakers
full
range
by
hooking
them
up
directly
to
the
amp.
In
many
systems, if
your
speakers
are
true
full-range systems,
you
may
find
that
you
get
a
more
satisfying sound
by
running
the
speakers
full
range
and
crossing your subwoofer
in
fairly
low
(40
-
70
Hz).
On
the
other
hand,
if
you
find
that
you
are
overdriving
your
main
speakers,
you
will
be
able
to
play
your
system
louder
by
using
the
built-in
high
pass
crossover
for your
main
speakers.
