Subwoofer Outputst

The Velodyne subwoofer is designed to operate using the full range audio signal for input when using the built-

incrossover.Someprocessors/receivershavea“subwooferout”jackthatisinternallylteredanddesignedto

beusedwithaconventionalamplierandspeaker.Insomerarecases,combiningbothanexternalcrossover

and the one internal to the subwoofer may result in low output and increased noise. In these installations you

may need to bypass the internal crossover in either the processor or Velodyne subwoofer. In some installations,

simplysettingonecrossovertoahigherfrequency(suchas 120Hz) willrestoremaximumperformance.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 XOVER/SUBWOOFER DIRECT on the rear panel of the subwoofer

and set to the SUBWOOFER DIRECT position. This will eliminate the internal crossover from the signal path.

NOTE:Ifnotusinganexternalcrossover,youshouldusethebuiltincrossoverforoptimalperformance.
