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 ® , dTS ® , THX™) have a “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.
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.
CARE OF YOUR SUBWOOFER
your Velodyne subwoofer does not require any regular maintenance. normal dusting or cleaning of the surface
for appearance purposes are all that is required. we suggest you avoid any harsh detergents or chemicals when
cleaning the cabinet. Abrasives, detergents, or cleaning solutions may damage the finish on the cabinet. We
recommend using only a damp cloth to clean the cabinet.
