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.
Regardless of where you install your Velodyne subwoofer, it must remain in an upright
position (woofer facing forward). Using, shipping, or otherwise storing the subwoofer in
any other position for an extended period of time may result in damage to the unit not
covered by warranty.
The FSX-12 subwoofer is not magnetically shielded. When installing near television
monitors, test placement with the monitor operational to observe any change in colors.
Certain types of televisions are particularly sensitive to stray magnetic fields. If your
television produces distorted colors after installing your subwoofer, simply increase the
distance between your television and the subwoofer, until normal color and operation is
returned.
Protection circuitry
––––––––––––––––––––––––––––––––––––—————––––––––––––––––––
Your new subwoofer is equipped with special protection circuitry to provide maximum
performance with greatest reliability.
The unit is protected against:
1)Overdriving the speaker or amplifier.
2)Overheating the amplifier.
3)Excessive drop in power line voltage.

Subwoofer outputs
The Velodyne subwoofer is designed to operate using the full range audio signal for input
when using the built-in crossover. Some processors/receivers, have a "subwoofer out" jack
that is internally filtered and designed to be used with a conventional amplifier and speaker.
In some rare cases, combining both an external crossover and the one internal to the
subwoofer may result in low output and increased noise. In these installations you may
need to bypass the internal crossover in either the processor or Velodyne subwoofer. In
some installations, simply setting one crossover to a higher frequency (such as 120 Hz) will
restore maximum performance.
To bypass the subwoofer's internal crossover when the unit is being fed a low pass signal
from another crossover, simply locate the switch marked X-over, OUT - IN on the rear panel
of the subwoofer and set to the OUT position. This will eliminate the internal crossover
from the signal path.
