2 - Impact Series User’s Manual
Placement
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.
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), linelevel 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.to produce less output than it is capable of.
