Congratulations!
Congratulations on your purchase of a Velodyne DLS subwoofer system. This system represents the state of the art in low frequency reproduction. Your new subwoofer features Velodyne's exclusive DLS (Distortion Limiting System) technology that significantly improves the subwoofer's performance by limiting audible amplifier distortion and controlling the driver excursion. The result is a subwoofer that reproduces music and hometheater with a fraction of the audible distortion found in lesser products. This exclusive DLS technology increases the detail and definition of your subwoofer without sacrificing output or dynamic impact. Read and follow the instructions below to insure safe and proper system operation. To prevent fire or shock hazard, do not expose this equipment to rain or moisture. 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. Low-pass crossover Both sets of inputs sum the left and right channels together and the resulting signal is passed through an adjustable low-pass crossover before being amplified. The crossover control allows you to adjust the upper limit of the subwoofer's frequency response from 40 to 120 Hz. The subwoofer's response will begin rolling off above the frequency you set this control to. You should set the crossover frequency to obtain a smooth and seamless transition from the subwoofer to the main speakers in your system. If your
Care of Your DLS Subwoofer
Do not use any harsh detergents or chemicals to clean the cabinet. Abrasives, detergents, or cleaning solutions may damage the finish on the cabinet. During normal conditions, the subwoofer may be left on continuously without any problems. The unit is equipped with a signal sensing circuit that will automatically turn on the unit when a signal is present at the inputs and turn off the unit after several minutes when there is no longer any signal at the inputs. If you plan to leave the unit unused for an extended period of time, we recommend that you turn off the unit by the master power switch on the rear panel.
continued. [. . . ] High pass crossover switch This switch selects the frequency for the high pass crossover. In some installations, it may be beneficial to have a steeper ultimate crossover slope. To do this you can use both your processor's crossover and the one internal to the DLS subwoofer. You should stagger the frequencies (i. e. , 120Hz sub, 80Hz processor) for best results. [. . . ]
