Note. . . .
If not using an external crossover, you should use the built-in crossover for
optimal performance.
Speaker-level connection
––––––––––––––––––––––––––––––––––––––––––––––––––––—————––
Figure 2 shows an easy way to connect your Velodyne subwoofer directly to your receiver
or integrated amplifier.
When connected in this fashion, your satellite speakers will be crossed over at 85Hz, which
removes the lower bass from your speakers, enabling them to do a better job reproducing
high frequencies.
You may also connect your satellites directly to your receiver or amplifier along with the
subwoofer if you wish to bypass the internal high-pass crossover.
Caution!!!
To avoid damage to your main amplifier, be sure to maintain correct polarity
when making all connections. Red (positive) to red, and black (negative) to
black. Be sure that all connections are tight, and that there are no loose strands
or frayed wires.
Interconnect cables
––––––––––––––––––––––––––––––––––––––––––––––––—————––––––
When installing your new Velodyne subwoofer using the line level connections, you should
always use shielded phono cables. There are many decent cables available today, most any
of which will work perfectly well. We do recommend that you keep the length of cable as
short as possible to avoid any potential noise problems.
When using speaker level connections, use a decent quality speaker cable that mates well
with the connectors. Be very careful to avoid any loose strands or frayed wires which may
result in a short, which may damage your equipment. Cables of extremely large size are
typically not required. Extremely large gauge wire may not properly fit in the binding posts,
resulting in a poor connection and possible short circuits.
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
it typically far away from any walls, and close to the center of your room. Avoid these
