Placement
True subwoofers operate at extremely low frequencies that are primarily omni-directional. Keep
i
n mind that frequency response and output level can be
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 ver

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.
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-

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

o 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

Phase Adjustment - 0°/180°
This control allows you to “reverse” the phase of the subwoofer’s output signal 180° to correct
f
or 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.

Crossovers
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

Interconnect Cables
W
hen 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 tur

Troubleshooting and Service
I
f 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 r
1. The power cord has become damaged.
2. The unit does not appear to operate nor
change in performance.
3. The unit has been exposed to water.
4. Some part of the cabinet or circuitry is physically damaged.
