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 high quality cables available today. It is recommended that you keep the length of cable as short as possible to avoid any potential noise problems.

When using speaker level connections, use a high quality speaker cable that mates well with the connectors. Be very careful to avoid any loose strands or frayed wires that 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.
