enced 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 subwoof-
ers in stereo, it is preferable to place each subwoofer by the satellite
of the same channel.
CAUTION!
The VA series subwoofers have amplifiers built into the cabinet. Do
not place the cabinet next to sources of heat such as furnace
registers, radiators, etc. The power cord should be routed in such a
way that it will not be walked on, pinched, or compressed in any way.
Regardless of where you install your VA-907.2 subwoofer, it must
remain in an upright position (passive radiator facing downward).
Using, shipping, or otherwise storing the VA-907.2 subwoofer in
any other position for an extended period of time may result in
damage to the unit not covered by warranty.
The VA-907.2 subwoofer is magnetically shielded to reduce mag-
netic emission from its cabinet to increase the number of possible
locations available for placement. However, this shielding may not
be adequate for all installations. Certain types of televisions are
particularly sensitive to stray magnetic fields. If your television
produces distorted colors after installation of your VA-907.2 sub-
woofer, simply increase the distance between your television and
the VA-907.2 until normal color and operation is returned.
Care of your subwoofer
Do not use any harsh detergents or chemicals to clean the cabinet.
Abrasives, detergents, or cleaning solutions may damage the finish
on the cabinet. We recommend using a damp cloth to clean the
cabinet.
During normal conditions, the VA-907.2 subwoofer may be left on
continued. . .
Installation
Your new VA-907.2 subwoofer system provides for a number of
installation options. Read all 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 off.
Inputs
Your new VA-907.2 subwoofer is equipped with both speaker-level
and line-level inputs. Use the LINE-IN jacks when connecting your
subwoofer to a pre-amp, signal processor, or line-level crossover.
The FROM AMPLIFIER jacks connect directly to the speaker
outputs of a integrated amplifier or receiver. Your amplifier section
will notice no additional loading effects when you use these inputs
because of their high impedance.
Note
Do not use both LINE-IN and FROM AMPLIFIER inputs simulta-
neously.
Caution!
Polarity is critical when using speaker level inputs. Reversing the
polarity of speaker level inputs can damage the unit.
Volume control
This control allows you to balance the output from the subwoofer to
the main speakers in your system. This control should be set to
achieve similar volume level from both the main speakers and
subwoofer.
Low-pass crossover
Both sets of inputs sum the left and right channels together and the
resulting signal is passed through an 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.
