the flow of air through the ventilation openings.
9. Heat -- The subwoofer should be situated away from heat sources such as radiators, heat registers, stoves,
or other subwoofers that produce heat.
10. Power Sources -- The subwoofer should be connected to a power supply only of the type described in the
operating instructions or as marked on the subwoofer.
11. Power-Cord Protection -- Power-supply cords should be routed so that they are not likely to be walked on or
pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience
receptacles, and the point at which they exit from the subwoofer.
12. "Caution: To prevent electrical shock, match wide blade of plug to wide slot, fully inserted." "Attention: Pour eviter
les chocs electriques, introduire lame la plus large de la fiche dans la borne correspondante de la prise et
pousser jusqu' au fond".
13. Cleaning -- The subwoofer should be cleaned only as recommended by the manufacturer.
14. Nonuse Periods -- The power cord of the subwoofer should be unplugged from the outlet when left unused for
a long period of time.
15. Object and Liquid Entry -- Care should be taken so that objects do not fall and liquids are not spilled onto the
enclosure.
16. Damage Requiring Service -- The subwoofer should be serviced by qualified service personnel when:
a. The power-supply cord or plug has been damaged.
b. Objects have fallen or liquid has been spilled into the subwoofer.
c. The subwoofer has been exposed to rain.
d. The subwoofer does not appear to operate normally or exhibits a marked change in performance.
e. The subwoofer has been dropped or damaged.
17. Servicing -- The user should not attempt to service the subwoofer beyond what is described in the operating

Prepare for Installation
Your new Velodyne subwoofer provides for a number of installation
options. Read all the installation information below in order to determine which installation option is best for your system. Remember
to perform all installation procedures with system power turned
off to prevent possible damage.
Placement
T rue subwoof ers operate at e xtremely low frequencies that are primarily omni-directional. K eep 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 lo w 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 electr onics 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 speak er’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.
Y our ne w V elodyne 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. W e 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-le vel crossover ,
or receiver with pre-amp lev el outputs. The SPEAKER LEVEL jac ks
connect directly to the speaker outputs of any amplifier , integ rated
amplifier, or receiv er. 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!
