RE . www. velodyne. com Optimum User's Manual 5 (1) Power Switch This button forces your Optimum subwoofer into standby mode. The sub will remain in this mode until the POWER button is pressed again. (2) LED Numeric Display This LED supplies information on volume, crossover, presets, and other information. (3) Volume Control These buttons allow you to balance the output from the subwoofer to the main speakers in your system. The volume should be set to achieve similar volume level of both the main speakers and subwoofer. The upper button increases the subwoofer level and the lower button decreases it. WARNING: Some manufacturers preset their receivers with the Sub-Out (A. K. A. It is very important to verify that your receiver Sub-Out channel is set to the same output level as your front right and left channels. Refer to your receiver manual for the individual channel level adjustment procedure. If your receiver Sub-Out channel is set too low, the subwoofer may appear to have a weak output, it may sound noisy or distorted, and the Auto On/Off feature may not operate properly.

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. 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. 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 Optimum User's Manual 10 Usage This section addresses day-to-day usage of your Optimum subwoofer.
