Regardless of where you install your Velodyne subwoofer, it must remain inanuprightposition(wooferfacingforward).Using,shipping,orotherwise storing the subwoofer in any other position for an extended period of time may result in damage to the unit not covered by warranty.

The subwoofer is magnetically shielded to reduce the amount of stray magnetic energy emitted from the speaker's motor structure. This greatly increases flexibility when placing the unit close to video monitors as there isverylittlestraymagnetism.However,thisshieldingmaynotbeadequate in certain extremely sensitive installations. Certain types of televisions areparticularlysensitivetostraymagneticfields.Ifyourtelevisionproduces distortedcolorsafterinstallingyoursubwoofer,simplyincreasethedistance betweenyourtelevisionandthesubwoofer,untilnormalcolorandoperation is returned.

Protection Circuitry

Your new subwoofer is equipped with special protection circuitry to providemaximumperformancewithgreatestreliability.

The unit is protected against:

1)Overdriving the speaker or amplifier.

2)Overheatingtheamplifier.

3)Excessive drop in power line voltage.

The first type of protection circuitry which prevents overdriving of the speaker or amplifier operates constantly without being audible under most situations.
