Placement
True subwoofers operate at extremely low frequencies that are primarily 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 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
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 furnace 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 result 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.
Your VRP 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 new Velodyne 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.
Ins tallation
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. When using the line level jacks, some
receivers may not provide enough signal to have the unit’s auto-on feature operate properly.
Additionally, this lack of signal may also cause the subwoofer to produce less output than it is
capable of.

To alleviate this condition, we recommend the following steps:
1)
If using line level jacks, BOTH THE LEFT AND RIGHT INPUT SHOULD ALWAYS BE USED
– never use just the left or just the right input. If the subwoofer’s input comes from the
LFE channel of your receiver, use the included “Y” splitter to divide the single input into
two inputs for the Left and Right subwoofer inputs. If using line level connections from
a preamp or signal processor, use both Left and Right inputs from your preprocessor or
preamp and connect them to the Left and Right inputs on your subwoofer.
2)
If using a receiver with LFE out, be sure the LFE channel is sending adequate signal to
the subwoofer. We recommend setting the subwoofer’s level to the 9 o’clock position
(the 1/4 volume setting) and then adjust the LFE channel on your receiver or processor
to achieve the desired bass output. See your receiver or processor’s owner’s manual for
more information.
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. 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!
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 two or three 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.
For all installations, experiment with the phase switch to determine the setting (0 or 180
degrees) that produces the most bass. If the settings sound similar, we recommend the
“0” position.
Auto Turn on Function
The subwoofer will turn itself on automatically when an audio signal is present. If no signal is
present for approximately eight minutes, the unit will switch to standby mode (Red LED). While
in standby mode, your subwoofer will draw very minimal power.

Receiver/Processor Subwoofer Outputs
The Velodyne 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 your VRP 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, pages 7 and 8 for connection diagrams.)

Interconnect Cables
When installing your new Velodyne subwoofer using the line level connections, you should
always use shielded phono cables. There are many high quality cables available today. It is
recommended that you keep the length of cable as short as possible to avoid any potential
noise 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 in the binding posts, resulting in a
poor connection and possible short circuits.
Care of Your Subwoofer
Your Velodyne 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.
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.

T roubleshooting 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.
Thank You for Purchasing a Velodyne!
