[. . . ] Retain Instructions -- The safety and operating instructions should be retained for future reference. Heed Warnings -- All warnings on the subwoofer and in the operating instructions should be adhered to. Follow Instructions -- All operating and use instructions should be followed. Water and Moisture -- The subwoofer should not be used near water -- for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, near a swimming pool or the like. [. . . ] Products forwarded to the factory authorized service representative should be shipped securely and properly packaged, insured and freight prepaid. 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 tucked away in a 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 and close to the center of your room. When using a pair of Velodyne subwoofers in stereo, it is preferable to place each subwoofer by the satellite of the same channel. Do not place the cabinet next to sources of heat such as furnace registers, radiators, etc. Do not place the unit near sources of excessive moisture, such as evaporative coolers, humidifiers, etc. The power cord should be routed in such a way that it will not be walked on, pinched or compressed in any way that could result in damaging the insulation or wire. Regardless of where you install your Velodyne subwoofer, it must remain in an upright position (woofer facing forward). Have all controls on the subwoofer (volume, crossover, phase, etc. ) been properly set?If unit has been running at high levels for an extended period of time, one of the protection circuits may be engaged. This function can be disabled by leaving the switch in the "on" position. Power Switch The master power switch is located on the lower half of the unit. This switch should be set to position 1 (up) for on, and 0 (down) for off. If the unit is to be left unused for an extended period of time, the master power switch should be turned off. 4 13 P SUBWOOFER OUTPUTS The Velodyne subwoofer is designed to operate using the full range audio signal for input when using the built-in crossover. Many home theater processors/receivers (Dolby Digital®, DTS®, THXTM) have a "subwoofer out" jack that is internally filtered and designed to be used with a powered subwoofer. In these installations, you may bypass the internal crossover in either the processor or the Velodyne subwoofer. 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 Velodyne sub. You should stagger the frequencies, (i. e. , 120 Hz sub, 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 INTERNAL X-OVER/SUBWOOFER DIRECT on the rear panel of the subwoofer and set to the SUBWOOFER DIRECT position. [. . . ] This may cause the unit to turn off when listening at low volume levels. If this occurs, simply use a "Y" adapter (available from most dealers) to allow your processor's single sub line to be fed into both L&R inputs. This will make the unit turn on at lower signal levels. P P CARE OF YOUR SUBWOOFER Your Velodyne subwoofer does not require any regular maintenance. Normal dusting or cleaning of the surface for appearance purposes are all that is required. [. . . ]
