Installation Your new subwoofer is equipped with speaker-level and line-level inputs. Use the LINE LEVEL jacks when connecting your subwoofer to a pre-amp, signal processor, line-level crossover or receiver with pre-amp level outputs. The SPEAKER LEVEL jacks connect directly to the speaker outputs of any amplifier, integrated amplifier or receiver. Your amplifier section will notice no additional loading effects when you use these inputs due to their very high impedance. Important!!! Do not use

Crossover Switch - INTERNAL X-OVER/SUBWOOFER DIRECT This switch allows the internal crossover circuitry to be removed from the signal path. This is r equired in certain installations which route the signal through external processors with a crossover circuit of their own, such as the new digital units. Simply move the switch to SUBWOOFER DIRECT to disengage the built-in crossover. For all other installations which do not have a separate electronic crossover, we recommend you leave the switch se

Figure 1. Installation Using LFE Line-Level Inputs Note: If not using an external crossover, you should use the built-in crossover for optimal performance. When using a single channel input (such as a surround sound processor’s subwoofer out or LFE), the auto on/off circuit sensitivity will be affected. When one input channel is used instead of two, the unit will see lower signal levels present at the inputs. This may cause the unit to turn off when listening at low volume levels. If this occur

Line-Level Connection - Option B Figure 2 shows connection from a pre-amplifier’s main outputs to the left and right inputs of your Velodyne subwoofer. You will also need to connect a second pair of RCA cables from the outputs on the back of your subwoofer to the inputs on the back of your amplifier. When the subwoofer is installed in this fashion, your satellite speakers will be crossed over at 80 Hz which removes the lower bass frequencies from your external amplifier and speakers, enabling th

Speaker-Level Connections Figure 3 shows an easy way to connect your Velodyne subwoofer directly to your receiver or integrated amplifier, if it lacks line-level outputs. You may also connect your satellites directly to your receiver or amplifier along with the subwoofer. Your receiver or amplifier will not notice the additional load of the subwoofer due to the high input impedance. Figure 3. Installation Using Speaker-Level Inputs Caution!!! To avoid damage to your main amplifier, be sure to

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 , THX™) 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 ulti

Care of Your Subwoofer Your Velodyne subwoofer does not require any regular maintenance. Normal dusting or cleaning of the surface for appearance purposes is all that is required. We suggest you avoid any harsh detergents or chemicals when cleaning the cabinet. Abrasives, detergents, or cleaning solutions may damage the finish on the cabinet. We recommend using only a damp cloth to clean the cabinet. During normal conditions, your new subwoofer may be left on continuously without any problems.
