SPL-Ultra Rear Panel Connections Figure 2 shows the connections on the rear panel of the SPL-Ultra. RE . www. velodyne. com SPL-Ultra User's Manual 7 Following are brief descriptions of the connections described in Figure 2. More detail on these connections can be found in the next section. (1) LOW-PASS CROSSOVER Use this knob to select the frequency above which you wish to roll off the signal to the subwoofer. When the knob is turned all the way to the left, the Subwoofer Direct feature is invoked and the subwoofer plays all frequencies up to 200 Hz. (2) 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 between both the main speakers and subwoofer. When pressing volume up or down, set the level while watching the LED display for reference. The upper button increases the subwoofer level and the lower button decreases it. 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. 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 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. . www. velodyne. com USAGE SPL-Ultra User's Manual 10 Usage This section addresses day-to-day usage of your SPL-Ultra subwoofer.
