Placement
The first step in installing your new VDR is to determine where it will be placed in the room.
U
npack the system carefully and use the following guidelines in order to find 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 influenced by
placement, depending on the acoustic properties of the listening room. To obtain optimum
output from your subwoofer, place it within a foot of a corner. This location will offer 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 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 find 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 r

Installation
Y
our 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.
