AWor d About Your Receiver’s Cr ossover and the Velodyne SPL - Ultra Subwoofer Cr ossover

Your Velodyne SPL-Ultra subwoofer is designed to operate using the full range audio signal for input when using the built-in crossover (controlled by the dial on the back panel). Many home theater processors/receivers (Dolby Digital®, DTS®, THX®) have a “subwoofer out” jack that performs this same function and are designed to be used with a powered subwoofer.

In these installations, you may want to bypass the crossover in either the processor or the Velodyne subwoofer. In some cases, you may want to use BOTH crossovers. 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 subwoofer, 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 rotate the knob marked “LOW-PASS CROSSOVER” on the rear panel of the subwoofer, turning 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 the best performance. When using a single RCA sub out from the processor, connect to the “L” - LFE input on the subwoofer, or for more signal, use a “Y” connector and feed the signal into both “R” and “L” inputs.

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 18-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.
