Prepare for Installation
Your newVelodyne subwoofer provides for a number of installation
options. Read allthe installationinformationbelow inorder todeter-
mine which installationoption isbestfor your system. Remember
to perform all installation procedures with system power fumed
offto prevent possible damage.
Placement
True subwoofers operate at extremely low frequencies that are pri-
marily omni-directional. Keep in mindthatfrequency response and
output level can bedrastically influenced byplacement, depending
on the acoustic properties of the listening room. Typically,the opti-
mum location for a subwoofer is tucked away in a comer of your
listening room. This location will usually offer the greatest output
levelsand optimum low frequency extension. The worst locationfor
a subwoofer istypically tar away from any walls, and close to the
center of your room. Avoid these locations when possible. When
using a pair of Velodyne subwoofers in stereo, it is preferable to
place each subwoofer bythe satellite of the same channel.
Caution! This subwoofer has electronics built into the cabinet.
Do not place the cabinet next to sources of heat such as fur-
nace registers, radiators, etc., or near sources of excessive
moisture, 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 re-
sult in damaging the insulation or wire.
Regardless of where you install your Velodyne subwoofer, it must
remain inan uprightposition (wooferfacing forward). Using,shipping,
or otherwise storing the subwoofer in any other position for an
extended periodoftime may resultindamage tothe unitnotcovered
bywarranty.
YourVRP subwoofer ismagnetically shielded toreduce the amount
ofstraymagnetic energy emittodfrom the speaker's motor structure.
This greatly increases flexibilitywhen placing the unitclose to video

monitors,asthereisverylittle stray magnetism. Certain types of
televisions are particularly sensitive to stray magnetic fields. If
your television produces distorted colors after installing your
subwoofer, simply increase the distance between your television
and the subwoofer untilnormal color and operation isreturned.
YournewVelodynesubwoofer,likeanygood speakersystem,requires
proper positioning within the listening space to provide maximum
performance. Improperly placed speakers may degrade the sound
quality and reduce your listening pleasure. Depending on the size
and type offurnishings in the room, perfect placement may not be
possible. Finding the best locationfor your environment will likely
require someexperimentation. We suggestyou experiment withthe
location during setup tofind what sounds bestto you when seated
in your typical listening position.
Inputs
Your new subwoofer is equipped with speaker-level and line-level
inputs. Usethe LINE LEVEL jackswhen connecting your subwoofer
to a pre-amp, signalprocessor(suchas LFE out),line-levelcrossover,
or receiverwith pre-amp level outputs.The SPEAKER LEVEL jacks
connect directly to the speaker outputs of any amplifier, integrated
amplifier, or receiver. Youramplifier section willnotice no additional
loading effects when you use these inputs due to their very high
impedance.
Note: You do notneed to connectboththeleftand right LINE LEVEL
inputs from a single source (such as the LFE out on your receiver/
processor). These inputs are summed together and simply
connecting one willprovidethe same amount ofsignalto the sub as
ifyou had used a =Y' connector and connected both. If using the
SPEAKER LEVEL inputs,you DO want to connect both channels,
since different bass information might be present in each channel
goingto your main speakers.
Important! U
Do not use both LINE LEVEL and SPEAKER LEVEL connections
simultaneously!
con#nu6d, , ,

Caution/!/To avoid damage to your main amplifier, be sure to maintain
correct polarity when making all connections - red (positive) to red,
and black (negative) to black. Be sure all connections are tight, and
that there are no loose strands or frayed wires.
Volume Control
This controlallows you to balance the outputfrom the subwoofer to
the main speakers/amplifier in yoursystem. This control should be
set to achieve similar output levels from both the main speakers
and subwoofer when listening to music. Agood starting point for
the volume control is2 or 3 graduations from minimum.
Low-pass Crossover- 50 to 200 Hz
As noted above, all inputs sum the leftand dght channels together,
with the resulting signal passing through an adjustable low-pass
crossover beforebeing amplified. The crossover control allows you
toadjust the upper limitofthe subwoofer'sfrequency response from
50 to 200 Hz. The subwoofer's response willbegin rollingoffabove
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 100-120 Hz) 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 80 Hz.
Phase Adjustment -0"/180°
This control allows you to =reverse" the phase of the subwoofer's
outputsignal 180 °tocorrect forany possiblemismatchand resulting
cancellationbetweenthe subwooferandyourmainspeakers/amplifier.
To adjust, simply listen to the system with music playing, then
depress the phase switch from one positionto the other and listen
for a change in low frequency output. The correct positionwill have
a greater amount of apparent lowfrequency output.
Auto Tam on Function
The subwoofer will turnitselfon automatically when an audio signal
is present. If no signal is present for approximately 8 minutes, the
unitwill switchto standby mode (Red LED). While in standbymode,
your subwoofer willdraw very minimal power.

Crossovers
Speaker-level Connections
When installedin thisfashion the satellite speakers will be crossed
over at 80 Hz. This ramoves the lowerbass from youramplifier and
speakers,enablingthem todoa betterjobreproducinghighfrequencies.
By utilizingthis method you willhave abi-amplified system, gaining
improved power and headroom for your system.
ReceivedProcessor Subwoofer Outputs
The Velodyne subwoofer isdesigned tooperate using the fullrange
audio signal for input when usingthe built-incrossover. Many home
theater processors/receivers (Dolby DigitaP, DTS®,THX ®)have a
"subwoofer out"jack (sometimes labeled "LFE") that is internally
filten_d,settable at the receiver/processor, and designed tobe used
with a powered subwoofer. In some installations,itmay bebeneficial
to use BOTH the Velodyne crossover and the raceiver/processor
crossover, resulting ina steeper ultimate crossover slope. In some
rare cases, combiningbeth an externalcrossoverand the one internal
to the subwoofer may result in low output and increased noise, in
these installationsyou may need to bypass the crossover in either
the processororyourVRP subwoofer,or simplysettingone crossover
to a higher frequency (such as 120 Hz) will restore maximum
performance.

When installing your new Velodyne subwoofer using the line level
connections, you should always use shielded phono cables. There
are many highqualitycables available today. Itisrecommended that
you keep the length of cable as short as possible to avoid any
potentialnoise problems.
When using speaker level connections, use a high quality speaker
cable that mates well with the connectors. Be very careful to avoid
any loose strands or frayed wires that may result in a short, which
may damage your equipment. Cables of extremely large size are
typically not required. Extremely large gauge wire may not properly
fit inthe binding posts, resulting in a poor connection and possible
short circuits.
YourVeledyne subwooferdoes notrequire anyregularmaintenance.
Normal dustingor cleaning ofthe surface for appearance purposes
isall that isrequired. We suggest you avoidany harshdetergents or
chemicals when cleaning the cabinet. Abrasives, detergents, or
cleaning solutions may damage the finish on the cabinet. We
recommend using onlya damp cloth to clean the cabinet.
During normal conditions, your new subwoofer may be left on
continuously without any problems. The unit is equipped with a
signal-sensing turn on/off that will automatically turn on the unit
when a signal is present at the inputs and turn off the unit after
several minuteswhen there isno longer any signal at the inputs.
Your new subwoofer isequipped with circuitrytoprovide maximum
performance with greatest reliability.
The unitis protected against:
1) Overheating the amplifler.
2) Excessive drop in power line voltage.

Ifeitheroftheaboveshouldhappen,youshouldreducethe volume
setting or shut the unitoff until normal operating conditions return.
You may also want to plug the unit into a different wall outlet, as
droppingpower linevoltagewillbe most noticeableunder strenuous
conditionsand may result in the unit shutting down intermittently.
If you should experience a problem with the operation of your
subwoofer, please check allofthe following before seeking service.
Following isa simple troubleshooting guide to assist you.
1. Verify that the unitisplugged in, the power outlet is active, and
issupplying propervoltage.
2. Is unitreceiving an input signal fi'omyour source?
3. Have all controls on subwoofer(volume, crossover,phase, etc.)
been properlyse_
4. Ifunithas been runningat high levels for an extended period of
time, one of the protection cimuits may be engaged.
Is the built-inamplifier extremely hot to the touch?
Isyour power linevoltage sagging, such as when there are
other devices on the same circuit drawing lots of power?.
If the protection circuitry is active, the unit may cycle on and off
until operating parameters return to normal. Under more serious
conditions, the unitmay shutoffcompletely.Normal operationshould
return upon cooling, but you may be required to turn the power off
and then on again to reset the unit.
The following conditions require service by a qualified technician:
1. The power cord has become damaged.
2. The unitdoesnotappeartooperate normallyorexhibitsa marked
change inperformance.
3. The unit has been exposed to water.
4. Some part of the cabinet or circuitryis physicallydamaged.
