Your new Velodyne subwoofer, like any good speaker system, requires
proper positioning within the listening space to provide maximum
performance. Improperly placed speakers may degrade the sound
quality and reduce your listening pleasure. Depending on the size and
type of furnishings in the room, perfect placement may not be possible.
Finding the best location within your environment will likely require some
experimentation. We suggest you experiment with the location during
setup to find what sounds best to you when seated in your typical
listening position.
INSTALLATION
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.
Important!!!
Do not use both LINE LEVEL and SPEAKER LEVEL
connections simultaneously!
Volume Control
This control allows you to balance the output from the subwoofer to the
main speakers/amplifier in your system. This control should be set to
achieve similar output level from both the main speakers and subwoofer
when listening to music. A good starting point for the volume control is 3
or 4 dots from minimum.
Low-pass Crossover - 40 to 120 Hz
All inputs sum the left and right channels together, with the resulting
signal passing 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 40 to 120 Hz. The
subwoofer’s response will begin rolling off above the frequency you set
this control to. You should set the crossover frequency to obtain a
smooth and seamless transition from the subwoofer to the main
speakers in your system. If your main speakers are smaller unit
s with
limited low frequency output, you may wish to choose a higher frequency
