Following are brief descriptions of the connections described in Figure 1. (1) LOW-PASS CROSSOVER Use this knob to select the high-frequency range at which you wish to cut off the signal to the subwoofer. [. . . ] 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 locate the switch marked "LOW-PASS CROSSOVER" on the rear panel of the subwoofer and turn it counterclockwise to the leftmost position. 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 on 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. 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 typically far away from any walls, close to the center of your room and near an opening or doorway. When using a pair of Velodyne subwoofers in stereo, it is preferable to place each subwoofer by the satellite of the same channel. In this case, the previous EQ settings will be preserved. PHASE These buttons allow you to optimize the subwoofer performance for the location and your listening position. The light will blink according to the following schedule: 0 degrees 90 degrees 180 degrees 270 degrees 1 2 3 4 blink blinks blinks blinks LIGHT If you wish, you can deactivate the blue front panel light on your SPL-R unit. To reactivate the light, press the LIGHT button again. NIGHT Night mode limits the maximum output of the subwoofer for later night listening or to be more considerate of close neighbors. Night mode, when active, is indicated by the reduced intensity of the light. VOLUME CONTROL This control allows you to balance the output from the subwoofer to the main speakers in your system. This control should be set to achieve similar volume level from both the main speakers and subwoofer. When pressing the volume up or down, the speed at which the power light blinks indicates subwoofer volume - the faster the blinking, the louder the unit plays. After the volume blinking stops, the unit will blink out the actual volume number.
