Prepare for Installation

Y

our 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 suited for
your system.

off to prevent possible damage.

PLACEMENT

True subwoofers operate at extremely low frequencies which are primarily omni-directional.
While it is recommended that the subwoofer be placed on the same plane as the satellite
speakers, room and system conditions often dictate otherwise. Keep 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 low 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 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.

Remember to perform all installation procedures with system power turned

Regar
(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 war

Your new Velodyne 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 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.

dless of where you install your Velodyne subwoofer, it must remain in an upright 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, line-level crossover or
receiver with pre-amp level outputs. The
outputs of any amplifier, integrated amplifier or receiver. Your amplifier section will notice no
additional loading effects when you use these inputs due to their very high impedance.

Important!!!
Do not use both LINE LEVEL and SPEAKER LEVEL connections simultaneously!

Volume Control

This control allows you to balance the output from the subwoofer to the main
speakers/amplifier in your system. This control should be set to achieve similar output level
from both the main speakers and subwoofer when listening to music. A good starting point for
the volume control is 3 or 4 dots from minimum.

Low-pass Crossover - 40 to 120 Hz

All inputs sum the left and right channels together, with the r
adjustable low-pass crossover before being amplified. The crossover control allows you to adjust
the upper limit of the subwoofer’s frequency response from 40 to 120 Hz. The subwoofer’s
response will begin rolling off above the frequency you set this control to. You should set the
crossover frequency to obtain a smooth and seamless transition from the subwoofer to the
main speakers in your system. If your main speakers are smaller units with limited low frequency
output, you may wish to choose a higher frequency (such as 100 -120 Hz) than you would with
