For example, the subwoofer should not be situated on a bed, sofa, rug, or similar surface that may block the ventilation openings; or placed in a built-in installation such as a bookcase or cabinet that may impede the flow of air through the ventilation openings. Heat -- The subwoofer should be situated away from heat sources such as radiators, heat registers, stoves, or other subwoofers that produce heat. [. . . ] Damage Requiring Service -- The subwoofer should be serviced by qualified service personnel when: a. The subwoofer does not appear to operate normally or exhibits a marked change in performance.

If you plan to leave the VA-806/907 unused for an extended period of time, we recommend that you turn off the unit by the master power switch on the rear panel. Congratulations! Congratulations on your purchase of a Velodyne VA-806/907 subwoofer system. This system represents the state of the art in accurate low frequency reproduction. The FROM AMPLIFIER jacks connect directly to the speaker outputs of a integrated amplifier or receiver. Your amplifier section will notice no additional loading effects when you use these inputs because of their high impedance. Note Do not use both LINE-IN and FROM AMPLIFIER inputs simultaneously. Volume control This control allows you to balance the output from the subwoofer to the main speakers in your system. To adjust the volume, start with the volume knob indicator at the "MIN" setting. With your other speakers playing, rotate the knob clockwise until you create a volume balance with your speakers. In most cases this will be somewhere between the "10 o'clock" and "2 o'clock" positions on the dial. Warning - Turning the volume to "MAX" setting may damage the subwoofer with certain source material. 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 50 to Care of your 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. [. . . ] If your main speakers are smaller units with limited low frequency output, you may wish to choose a higher frequency (such as 100-120hz) than you would with larger speakers which have greater low frequency output. With larger speakers, you might start with this control set lower, such as 80hz. VOLUME FREQUENCY CAUTION! WARNING: AVIS: +R - - L + MAIN OUTPUTS (speaker-level) Phase adjustment This control allows you the ability to compensate for having the subwoofer in a different location than the main speakers. Ideally, you will have the sound from the subwoofer reach the listening position the same time as the sound from the main speakers. However, if the distance from the listening position to the subwoofer and the distance from listening position to the main speakers differs, the sound from each will reach your ears at a different time. + + - INTEGRATED AMP / RECEIVER SATELLITE SPEAKERS This control allows the signal to be delayed 180 degrees so the output of the subwoofer will blend in to that of your main speakers without any cancellation. Interconnect cables When installing your VA-806/907 using the line-level inputs/outputs, you should use standard shielded phono cables. [. . . ]
