Use this knob to select the high-frequency range at which you
wish to cut off the signal to the subwoofer. When the knob is
turned all the way to the left, the Subwoofer Direct feature is
invok ed and the subwoof er plays all frequencies up to 200 Hz.
(2) PHASE Switch
Allows you to optimize the subwoofer performance for the location and your listening position. Select the switch position
at which you hear more bass.
(A) LINE INPUT/LFE Input
Connect these jacks to the LINE OUT preamp output, LFE
output or subwoofer output jack(s) of your receiver/processor.
If using the LFE output from your receiver or processor, plug
the single cable into the “L” – LFE input.
(B) SPEAKER LEVEL INPUT Terminals
Connect these input terminals to the speaker output terminals
of your amplifier or receiver . If y ou use this method of connection, when you go to the receiver speaker set up menu, make
sure you select the large speaker option.
Note: Do not use both the LINE INPUT/LFE Input connections and
SPEAKER LEVEL INPUT connections simultaneously.
(C) SPEAKER LEVEL OUTPUT Terminals
Sends a speaker-level signal to the front speakers.
Caution!!!
T o a void damage to your main amplifier , be sure to maintain correct
polarity when making all connections. Red (positive) to red, and
black (negative) to black. Be sure that all connections are tight,
and that there are no loose strands or frayed wires.
Power Switch
The master power switch is located on the lower right half of the
unit. This rocker style switch is the main on/off for the unit. This

Rear Panel Connections - Detailed Explanation
Your new subwoofer is equipped with both speaker-level and linelevel inputs. Use the RCA/Phono type “INPUT” jacks when connecting your subwoofer to a pre-amp, signal processor, or line-level
crossover. The “SPEAKER LEVEL INPUT” jacks connect directly
to the speaker outputs of an integrated amplifier or receiver. Your
amplifier section will notice no additional loading effects when you
use these inputs because of their high impedance.
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
40 to 120 Hz. The subwoof er’s response will begin rolling off abo ve
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 units with limited
low frequency output, you may wish to choose a higher frequency
(such as 100-120 Hz) 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 80 Hz.
Subwoofer Direct
Subwoofer Direct is a setting on the low-pass crosso ver knob and
will allow frequencies up to 200 Hz into the subwoofer. If you are
not using an external crossover, we recommend that you use the
one provided within the DPS unit for optimum performance.
Phase Adjustment - 0°/180°
This control allows you to “reverse” the phase of the subwoofer’s
output signal 180° to correct for any possib le mismatch and resulting cancellation between the subwoofer and your main speakers.
To adjust, simply listen to the system with music playing. Then
move the switch from one position to the other and listen for a
change in low frequency output. The correct position will have a
greater amount of apparent low frequency output.

Speaker Level Output
When connected in this fashion, your satellite speakers will be
crossed over at 80 Hz. This removes the lower bass from your
satellites, enabling them to do a better job reproducing high
frequencies and giving your receiver’ s amp more headroom (up to
50% more power).
You may also connect your satellites directly to your receiver or
amplifier along with the subwoofer if you wish to bypass this
crossover.
Caution!!!
T
o avoid damage to y our main amplifier , be sure to maintain correct
polarity when making all connections. Red (positive) to red, and
black (negative) to black. Be sure that all connections are tight,
and that there are no loose strands or frayed wires.
Power Switch
The master power switch is located on the lower right half of the
unit. This rocker style switch is the main on/off for the unit. This
switch should be set to position 1 for on (up), 0 for off (down).
A Word About Your Receiver’s Crossover and the
DPS Crossover
Your Velodyne DPS subwoofer is designed to operate using the
full range audio signal for input when using the built-in crossover
(controlled by the dial on the back panel). Many home theater
processors/receivers (Dolby Digital®, DTS®, THX®) have a
“subwoofer out” jack that performs this same function and are
designed to be used with a powered subwoofer.
In these installations, you may want to bypass the crossover in
either the processor or the Velodyne subwoofer. In some cases,
you may want to use BOTH crossovers. To do this, you can use
both your processor’s crossover and the one internal to the
Velodyne sub. You should stagger the frequencies (i.e., 120 Hz
subwoofer, 80 Hz processor) for best results.
To bypass the subwoofer’s internal crossover when the unit is being fed a low pass signal from another crossov er , simply locate the
knob marked “LOW-PASS CROSSOVER” on the rear panel of the
continued. . .

subwoofer and turn it counterclockwise to the “DIRECT” position.
This will eliminate the internal crossover from the signal path.
Note:
If not using an external crossover, you should use the built-in crossover
for optimal performance. When using a single RCA sub out from the
processor, it does not matter which line level input (L/R) is used.
Interconnect Cables
When installing your new Velodyne subwoofer using the line-level
connections, you should alwa ys use shielded phono cables. There
are many decent cables available today, most any of which will
work perfectly well. W e do recommend that you k eep the length of
cable as short as possible to avoid any potential noise problems.
When using speaker level connections, use a decent quality
speaker cable that mates well with the connectors (at least 14
gauge). Be very careful to avoid any loose or frayed strands that
could result in a short, causing a dangerous condition and possible
damage to your unit. Cables of extremely large size are typically
not required. Extremely large gauge wire may not properly fit in
the binding posts, resulting in a poor connection and possible short
circuits.
Placement
True subwoofers operate at extremely low frequencies, which are
primarily omni-directional. While it is recommended that the
subwoofers be placed on the same plane as the satellite speakers ,
room and system conditions often dictate otherwise. Keep in mind
that frequency response and output level can be drastically
influenced by placement, depending on the acoustic properties of
your listening room. Typically , the optimum location for a subwoof er
is in a front corner of your listening room. This location will usually
offer the greatest output levels and optimum low frequency
extension. The worst location f or a subw oofer is typically far away
from any walls, close to the center of your room and near an opening
or door way. Avoid these locations when possible. When using a
pair of V elodyne subw oofers in stereo , it is preferab le to place each
subwoofer near the satellite of the same channel. Typically, a
minimum distance of 1 to 2 feet from your TV to the subwoofer will
be adequate to avoid any magnetic interference.

Caution!
This subwoofer has electronics built into the cabinet. Do not place the
cabinet next to sources of heat such as furnace registers, radiators, etc.
Do not place the unit near sources of excessive moisture, such as
evaporativ e coolers , humidifiers, etc. The po wer cord should be routed in
such a way that it will not be walked on, pinched, or compressed in any
way that could result in damaging the insulation or wire.
Care of Your Subwoofer
Do not use any harsh detergents or chemicals to clean the cabinet.
Abrasives, detergents , or cleaning solutions will damage the finish
on the cabinet. We recommend using a damp cloth to clean the
front, back and sides. Use a soft cloth with a good quality furniture
polish to clean the hand-rubbed, black lacquer, painted top.
During normal conditions, the subwoofer may be left on
continuously without any problems. If you plan to leave the unit
unused for an extended period of time, we recommend that you
turn off the unit by the master power switch on the rear panel.
Troubleshooting and Service
Before seeking service for your subwoofer, please re-check all
systems. Following is a simple troubleshooting guide to assist y ou.
1. Verify unit is plugged in and power outlet used is active.
2. Is power switch on?
3. Is unit receiving an input signal from your source?
4. Have all controls on subwoof er (volume, crossov er, phase, etc.)
been properly set?
5. If unit has been running at high levels, one of the protection
circuits may be engaged.
6. Has the built-in amplifier overheated?
If the protection circuitry is active, the unit may cycle on and off
until operating parameters return to normal. Under more serious
conditions, the unit may shut off completely. Normal operation will
return upon cooling, but you may be required to turn the power off
and then on again to reset the unit.
