PREPARE FOR INSTALLATION
Your new Velodyne subwoofer provides for a number of installation options. Read all of 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 o to prevent possible damage.
PLACEMENT
The rst step in installing your new DEQ-R sub is to determine where it will be placed in the room. Unpack the
system carefully and use the following guidelines in order to nd the best room placement option.
True subwoofers operate at extremely low frequencies which are primarily omni-directional. Keep in mind that
frequency response and output level can be drastically inuenced by placement, depending on the acoustic
properties of the listening room. To obtain optimum output from your subwoofer, try placing it within a foot of a
corner. This location will oer the greatest output levels and optimum low frequency extension. If at all possible,
your subwoofer should be placed along a wall. 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 feed each subwoofer with one channel and place each subwoofer near
the satellite of the same channel.
Depending on the size and type of furnishings in the room, perfect placement may not be possible. Finding the
best location within your environment will likely require some experimentation. We suggest you experiment with
the location during setup to nd what sounds best to you when seated in your typical listening position.
Regardless of where you install your Velodyne subwoofer, it must remain in an upright position (woofer facing
forward). Using, shipping or storing the subwoofer in any other position for an extended period of time may
result in damage to the unit not covered by warranty.
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. Do not place the unit near sources of excessive moisture such
as evaporative coolers, humidiers, 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 damage to the insulation or wire.
Your Velodyne DEQ-R subwoofer is NOT magnetically shielded. Should you nd it necessary to use it with
an older CRT monitor or TV, keep it at least two feet from the monitor. Experiment for correct distance by
minimizing distortion of the picture and colors.
