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 proper
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 sour
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 for
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.
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), linelevel 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’
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

, or receiver. Your amplifier section will notice no additional loading effects when you
ferent bass information might be present in each
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 - r
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.
