Impact Series User’s Manual
P l a c e m e n t
The first step in installing your new Impact sub is to determine where it will be placed in the
room. Unpack 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, try placing 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 2-channel 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 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.
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, 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.
Your Velodyne Impact subwoofer is NOT magnetically shielded. Should you find 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.
I n p u t s
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.
