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 “LOW-PASS CROSSOVER” on the rear panel of the subwoofer and turn it counterclockwise to the leftmost position. This will eliminate the internal crossover from the signal path.
NOTE: If you are not using an external crossover, you should use the built-in crossover for optimal performance. When using a single RCA sub out from the processor, connect to the “L” - LFE input in the subwoofer.
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 quality speaker cable that mates well with the connectors (at least 14-gauge). Be very careful to avoid any loose or frayed strands that could result in a short, causing a dangerous condition and possible damage to your unit. 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 in a front 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 is
