SPEAKER-LEVEL CONNECTIONS
Figure 3 shows an easy way to connect your Velodyne subwoofer directly
to your receiver or integrated amplifier, if it lacks line-level outputs. You may
also connect your satellites directly to your receiver or amplifier along with
the subwoofer. Your receiver or amplifier will not notice the additional load
of the subwoofer due to the high input impedance.

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.

SUBWOOFER OUTPUTS
The Velodyne subwoofer is designed to operate using the full range
audio signal for input when using the built-in crossover. Many home
theater processors/receivers (Dolby Digital
"subwoofer out" jack that is internally filtered and designed to be used
with a powered subwoofer. In these installations, you may bypass the
internal crossover in either the processor or the Velodyne subwoofer. In
some installations, it may be beneficial to have a steeper ultimate
crossover slope. To do this, you can use both your processor's
crossover and the one internal to the Velodyne sub. You should stagger
the frequencies, (i.e., 120 Hz sub, 80 Hz processor) for best results.
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 INTERNAL X-OVER/SUBWOOFER DIRECT on the rear panel
of the subwoofer and set to the SUBWOOFER DIRECT position. This
will eliminate the internal crossover from the signal path.
P
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.
