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.

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.
