A
Word
About
Your
Receiver's
Crossover
and
the
Velodyne
Optimum
Subwoofer
Crossover
Your Velodyne Optimum subwoofer is designed
to
operate using
the
full range audio signal
for
input when using
the
built-in crossover (controlled
by
the
dial
on
the
back panel). Many home
theater
processors/receivers
(Dolby
Digital®,
DTS®,
THX®)
have a "subwoofer out" jack
that
performs
this
same function and are designed
to
be used with a powered subwoofer.
In
these installations,
you
may
want
to
bypass
the
crossover
in
either
the processor or
the
Velodyne subwoofer.
In
some cases,
you
may
want
to
use
BOTH
crossovers.
To
do this,
you
can
use both your processor's crossover and the one internal
to
the
Velodyne sub.
You
should
stagger
the
frequencies, (i.e.,
120
Hz
subwoofer,
80
Hz
processor)
for
best
results.
To
bypass
the
subwoofer's internal crossover when
the
unit is being fed a low pass signal
from
another
crossover, simply
rotate
the
knob marked "LOW-PASS
CROSSOVER"
on
the
rear
panel
of
the
subwoofer, turning
it
counterclockwise
to
the
leftmost
position. This will eliminate
the
internal crossover
from
the signal path.
Note:
If
you are
not
using
an
external crossover,
you
should use
the
built-in crossover
for
the
best
performance.
When
using a single
RCA
sub out
from
the
processor, connect to
the
"L" -
LFE
input
on
the
subwoofer,
or
for
more
signal, use a "Y"
connector
and feed
the
signal
into both "R" and "L" inputs.
INTERCONNECT
CABLES
When
installing your new Velodyne subwoofer using
the
line-level connections,
you
should always
use shielded phono cables. There are many
decent
cables available today,
most
any of which
will work perfectly well.
We
do recommend
that
you
keep
the
length of cable as
short
as
possible
to
avoid any potential noise problems.
When
using speaker level connections, use a quality speaker cable
that
mates
well with
the
connectors
(at
least 18-gauge). Be very careful
to
avoid any loose
or
frayed
strands
that
could
result
in
a
short,
causing a dangerous condition and possible damage
to
your unit. Cables of
extremely large size
are
typically
not
required. Extremely large gauge wire may not properly fit
in
the
binding posts, resulting
in
a poor connection and possible
short
circuits.
