equipped with both speaker-level and line-
level inputs, Use the LINE-IN jacks when connecting your sub-
woofer to a pre-amp, signal processor, or line-level crossover, The
FRO
M AMPLIFI
ER
jacks connect directly to the speaker outputs of
a
in
tegrated amplifier or receive
r.
Your amplifier section will notice
no additional loading effects when you use these inputs because of
their high impedance,
Note
Do not use both LINE-IN
and
FROM AMPLIFIER inputs simulta-
neously,
Volume
control
Th
is
control allows you to balance the output from the subwoofer to
the main speakers in your system, This control should be set to
achieve similar volume level from both the main speakers and
subwoofer,
Low-pass
crossover
Both sets of inputs sum the left and right channels together and the
resulting Signal is passed through an adjustable low-pass crossover
before being amplified, The crossover control allows you to adjust
the upper limit
of
the
subwoofe~s
frequency response from 40 to
120 hz, The
subwoofe~s
response will begin rolling off above the
frequency you set this control to,
You should set the crossover frequency to obtain a smooth and
seamless transition from the subwoofer to the main speakers in
your system, If your main speakers are smaller units with limited low
frequency output, you may wish to choose a higher frequency (such
as 100-120hz) than you would with larger speakers which have
greater low frequency output. With larger speakers, you might start
with this control set lower, such as 80hz,

When installed
in
this fashion, your satellite speakers will be
crossed
over
at 80/1
OOHz
(or 85Hz for CT -100) which removes the
lower bass from your amplifier and speakers, enabling them to do
a better job reproducing high frequencies. By utilizing this method,
you will have a bi-amplified system, gaining improved power and
headroom for your system.

external crossover and the
one
internal to the subwoofer may result
in low output and increased noise.
In
these installations you
may
need to bypass the internal crossover in either the processor
or
Velodyne subwoofer.
In
some installations, simply setting one
crossover to a higher frequency (such as 120 Hz) will restore
maximum performance.
To bypass the
subwoofe~s
internal crossover when the unit is
being fed a low pass signal from another crossover, simply locate
the switch marked X-over, OUT -IN on the rear panel of the
subwoofer and set to the OUT position. This will eliminate the
internal crossover from the signal path.
Note
...
If
not
using
an
external
crossover
,
you
should
use
the
built-in
crossover
for
optimal
performance.
Speaker-level connection
Figure 2 shows an easy way to connect your Velodyne subwoofer
directly to your receiver or integrated amplifier.
When connected in this fashion, your satellite speakers will be

You may also connect your satellites directly to your receiver

Interconnect cables
When installing
your
new
Velodyne subwoofer using the line level
connections,
you
should
always
use shielded
phono
cables. There
are
many
decent
cab
les available today, most
any
of
which
will
work perfectly well.
We
do
recommend t
ha
t you
keep
the length of
cable
as
short as possible
to
avoid any potential
noise
problems.
When using
speaker
level connections, use a decent
qua
lity
speaker
cable
that mates well with the connectors.
Be
very
ca
reful
to avoid
any
loose strands
or
frayed wires which
may
result in a
short, which
may
damage
y
our
equipment.
Cab
les
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.
Placement
True
subwoofers
operate at extremely low frequencies
which
are
primarily omni-directional.
While
it is recommended that the

subwoofer be placed on the same plane as the satellite speakers,
room and system conditions often dictate otherwise. Keep in mind
that frequency response and output level can be
drastically
influenced by placement, depending
on
the acoustic properties of
the listening room. Typically, the optimum location for a subwoofer
is tucked away in a corner of your listening room. This location will
usually offer the greatest output levels and optimum low frequency
extension. The worst location for a subwoofer it typically far away
from any walls, and close to the center of your room. Avoid these
locations when possible. When using a pairofVelodyne subwoofers
in
stereo,
it
is preferable to place each subwoofer by the satellite of
the same channe
l.
Typically, a minimum distance of 1
to
2 feet from
your TV to the subwoofer
wi
ll
be
adequate to avoid any magnetic
interferance.
Caution!
This
subwoofer
has
electronics
built
into
the
cabinet.
Do
not
place
the
cabinet
next
to
sources
of
heat
such
as
furnace
registers,
radiators,
etc.
Do
not
place
the
unit
near
sources
of
excessive moistures such
as
evaporative coolers, humidifiers,
etc. The
power
cord
should
be
routed
in
such
a
way
that
it
will
not
be
walked
on,
pinched,
or
compressed
in
any
way
that
could
result
in
damaging
the
insulation
or
wire,
Care
of
your subwoofer
Do not use any harsh detergents or chemicals to clean the cabinet.
Abrasives, detergents, or cleaning solutions may damage the finish
on the cabinet.
We
recommend using a damp cloth to clean the
cabinet.
During normal conditions, the subwoofer may be left on continu-
ously without any problems. The unit is equipped with a signal
sensi
ng
tum on/off that will automatically tum
on
the unit when a
signal is present at the inputs and turn off the unit after several
minutes when there is no longer any signal at the inputs.
If you plan to leave the unused for an extended period of time, we
recommend that you turn off the unit by the master power switch on
the rear pane

Resolution
des
problemes &
Entretien
Avant
de
vous adresser II un service
de
reparation pour votre
enceinte d'extremes graves, faites une double verification de tous
les systemes. Vous trouverez ci-dessous un guide simple de
resolution de problemes:
1. Verifier que votre enceinte est branchee correctement et que
Ie
reseau electrique fonctionne.
2. L'enceinte est-elle sur la position de marche ?
3. Le bouton de mise
en
marc he automatique on/off est-il regie
correctement?
4. Est-ce que votre enceinte
re~oit
un signal d'entree
de
la
source
elect rique ?
5. Est-ce que
tous
les
boutons
de
cont
role ont ete regles
correctement? (volume, coupure, phase ... )
6. Si vous avez pousse votre enceinte II son niveau de marche
maximum trop longtemps,
il
est probable que I'un des circuits
de protection soit endommage.
L'amplificateur incorpore a-t-il surchauffe?
Si les circuits de protection sont actifs, I'enceinte peut se mettre en
marche et s'arn§ter automatiquement pendant un certain temps
jusqu'
ll
ce que les parametres de marche redeviennent normaux.
Dans des conditions encore plus graves, I'enceinte peut s'arreter
completement.
Un
mode de fonctionnement normal
se
retablira
des
que I'enceinte aura refroidi ; il est toutefois possible que vous
ayez II I'arreter completement pour remettre II zero I'unite de
commande.
Les problemes suivants necessitent de faire appel a un technicien
qualifie:
1 .
Le
cordon electrique est endommage
2. L'enceinte montre des signes de malfonctionnement
3. L'enceinte a ete exposee II de I'eau
4. Certaines parties du coffret
ou
du reseau de circuits sont
abimees.
Merci d'avoir achete une enceinte Velodyne !
