Installation
–––––––––––––––––––––––––––––––––––––––––––––––––—————–––––
Your new Velodyne servo subwoofer provides for a number of installation options. Read
all the installation information below in order to determine which installation option is best
for your system. Remember to perform all installation procedures with system
power turned off!!!
Inputs
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.

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. We recommend using a damp
cloth to clean the cabinet.
During normal conditions, your new subwoofer may be left on continuously without any
problems. The unit is equipped with a signal-sensing turn on/off that will automatically turn
on the unit when a signal is present at the inputs and turn off the unit after several minutes
when there is no longer any signal at the inputs. If you plan to leave the subwoofer unused
for an extended period of time, we recommend that you turn off the master power switch
on the rear panel.
