Prepare for Installation  
Your newVelodyne subwoofer provides for a number of installation  
options. Read all the installation information below in order to deter-  
mine which installation option is best for your system. Remember  
to perform all installation procedures with system power turned  
off to prevent possible damage.  
Placement  
True subwoofers operate at extremely low frequencies that are pri-  
marily omni-directional. 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 opti-  
mum 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 is typically far 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 by the 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 in an upright position (woofer facing forward). Using, shipping,  
or otherwise storing the subwoofer in any other position for an  
extended period of time may result in damage to the unit not covered  
by warranty.  
YourVRP subwoofer is magnetically shielded to reduce the amount  
of stray magnetic energy emitted from the speaker’s motor structure.  
This greatly increases flexibility when placing the unit close to video

monitors, as there is very little 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 until normal color and operation is returned.  
Your newVelodyne subwoofer, like any good speaker system, 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 of furnishings in the room, perfect placement may not be  
possible. Finding the best location for your environment will likely  
require some experimentation. We suggest you experiment with the  
location during setup to find what sounds best to you when seated  
in your typical listening position.  
Installation  
Inputs  
Your new subwoofer is equipped with speaker-level and line-level  
inputs. Use the LINE LEVEL jacks when connecting your subwoofer  
to a pre-amp, signal processor (such as LFE out), line-level crossover,  
or receiver with pre-amp level outputs. The SPEAKER LEVEL jacks  
connect directly to the speaker outputs of any amplifier, integrated  
amplifier, or receiver. Your amplifier section will notice no additional  
loading effects when you use these inputs due to their very high  
impedance.  
Note: You do not need to connect both the left and 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 will provide the same amount of signal to the sub as  
if you 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  
going to your main speakers.  
Important!!!  
Do not use both LINE LEVEL and SPEAKER LEVEL connections  
simultaneously!  
continued. . .

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 control allows you to balance the output from the subwoofer to  
the main speakers/amplifier in your system. This control should be  
set to achieve similar output levels from both the main speakers  
and subwoofer when listening to music. A good starting point for  
the volume control is 2 or 3 graduations from minimum.  
Low-pass Crossover - 50 to 200 Hz  
As noted above, all inputs sum the left and right channels together,  
with the resulting signal passing through an adjustable low-pass  
crossover before being amplified. The crossover control allows you  
to adjust the upper limit of the subwoofer’s frequency response from  
50 to 200 Hz. The subwoofer’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 100-120 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  
output signal 180°to correct for any possible mismatch and resulting  
cancellation between the subwoofer and your main speakers/amplifier.  
To adjust, simply listen to the system with music playing, then  
depress the phase switch from one position to the other and listen  
for a change in low frequency output. The correct position will have  
a greater amount of apparent low frequency output.  
Auto Turn on Function  
The subwoofer will turn itself on automatically when an audio signal  
is present. If no signal is present for approximately 8 minutes, the  
unit will switch to standby mode (Red LED). While in standby mode,  
your subwoofer will draw very minimal power.

Crossovers  
Speaker-levelConnections  
When installed in this fashion the satellite speakers will be crossed  
over at 80 Hz. This removes the lower bass from your amplifier and  
speakers,enablingthemtodoabetterjobreproducinghighfrequencies.  
By utilizing this method you will have a bi-amplified system, gaining  
improved power and headroom for your system.  
Receiver/ProcessorSubwooferOutputs  
TheVelodyne subwoofer is designed to operate using the full range  
audio signal for input when using the built-in crossover. Many home  
theater processors/receivers (Dolby Digital®, DTS®, THX®) have a  
“subwoofer out” jack (sometimes labeled “LFE”) that is internally  
filtered, settable at the receiver/processor, and designed to be used  
with a powered subwoofer. In some installations, it may be beneficial  
to use BOTH the Velodyne crossover and the receiver/processor  
crossover, resulting in a steeper ultimate crossover slope. In some  
rare cases, combining both an 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 crossover in either  
the processor or yourVRP subwoofer, or simply setting one crossover  
to a higher frequency (such as 120 Hz) will restore maximum  
performance.  
(Refer to Figure 2a Line-Level Subwoofer Connection Diagram and  
Figure 2b Speaker-Level Subwoofer Connection Diagram, page 8  
and 9 for connection diagrams.)

Interconnect Cables  
When installing your new Velodyne subwoofer using the line level  
connections, you should always use shielded phono cables. There  
aremanyhighqualitycablesavailabletoday. Itisrecommendedthat  
you keep the length of cable as short as possible to avoid any  
potentialnoiseproblems.  
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 in the binding posts, resulting in a poor connection and possible  
short circuits.  
Care of Your Subwoofer  
YourVelodyne subwoofer does not require any regular maintenance.  
Normal dusting or cleaning of the surface for appearance purposes  
is all that is required. We suggest you avoid any harsh detergents or  
chemicals when cleaning the cabinet. Abrasives, detergents, or  
cleaning solutions may damage the finish on the cabinet. We  
recommend using only a 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 minutes when there is no longer any signal at the inputs.  
Protection Circuitry  
Your new subwoofer is equipped with circuitry to provide maximum  
performance with greatest reliability.  
The unit is protected against:  
1) Overheating the amplifier.  
2) Excessive drop in power line voltage.  
10  
Download from Www.Somanuals.com. All Manuals Search And Download.  
If either of the above should happen, you should reduce the volume  
setting or shut the unit off until normal operating conditions return.  
You may also want to plug the unit into a different wall outlet, as  
dropping power line voltage will be most noticeable under strenuous  
conditions and may result in the unit shutting down intermittently.  
Troubleshooting and Service  
If you should experience a problem with the operation of your  
subwoofer, please check all of the following before seeking service.  
Following is a simple troubleshooting guide to assist you.  
1. Verify that the unit is plugged in, the power outlet is active, and  
is supplying proper voltage.  
2. Is unit receiving an input signal from your source?  
3. Have all controls on subwoofer (volume, crossover, phase, etc.)  
been properly set?  
4. If unit has been running at high levels for an extended period of  
time, one of the protection circuits may be engaged.  
Is the built-in amplifier extremely hot to the touch?  
Is your power line voltage 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 unit may shut off completely. Normal operation should  
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 unit does not appear to operate normally or exhibits a marked  
change in performance.  
3. The unit has been exposed to water.  
4. Some part of the cabinet or circuitry is physically damaged.
