Crossover switch - In/Out
This switch allows the electronic crossover circuitry to be removed from the
signal path. This is preferable in certain installations which route the signal
through external processors with a crossover circuit of their own, such as
the new digital units. Simply move the switch to OUT to disengage the built
in crossover. For all other installations which do not have a separate
electronic crossover we recommend you leave the internal crossover IN
to provide optimum performance.
Auto turn on function
With this function in the "auto" position, your subwoofer can be safely left
with the main power switch on continuously. The subwoofer will turn itself
on automatically when an audio signal is present. If no signal is present for
approximately 15 minutes, the unit will switch to standby mode. While in
standby mode, your subwoofer will draw very minimal power. This
function can be disabled by leaving the switch in the "on" position.
Remote sensor
This connection allows for hook-up of the optional remote control receiver. With
this optional receiver plugged in you will be able to utilize the functions of the remote
to control power, volume and mute functions. Place the infrared receiver within direct
line of sight from your usual listening position.
Detachable power cord
Allows for easy replacement should the original be damaged.

for a subwoofer is tucked away in a corner of your listening room. This
location will usually provide the greatest output levels with optimum low
frequency extension. The worst location for a subwoofer it 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.
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.
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.
