P r e p a r e f o r I n s ta l l a t i o n
Your new Velodyne subwoofer provides for a number of installation options. Read all the
installation information below in order to determine which installation option is best suited for
your system. Remember to perform all installation procedures with system power turned
off to prevent possible damage.
PLACEMENT
True subwoofers operate at extremely low frequencies which are primarily omni-directional.
While it is recommended that the subwoofer 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 the listening room. Typically, the optimum location for a subwoofer is tucked away
in a corner of your listening room. This location will usually offer the greatest output levels and
optimum low frequency extension. The worst location for a subwoofer is typically far away from
any walls and close to the center of your room. Avoid these locations when possible. When
using a pair of Velodyne subwoofers in stereo, it is preferable to place each subwoofer by the
satellite of the same channel.
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 evaporative coolers, humidifiers, etc. The
power 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.
Regardless of where you install your Velodyne subwoofer, it must remain in an upright position
(woofer facing forward). Using, shipping or storing the subwoofer in any other position for an
extended period of time may result in damage to the unit not covered by warranty.
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.

I n s ta l l a t i o n
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 Contr ol
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 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.
A bypass switch is also provided if you wish to use an external crossover. If you are not using
an external crossover, we recommend that you use the one provided within the 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 possible mismatch and resulting cancellation between the subwoofer and your main
speakers/amplifier. 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.
Crossover Switch - INTERNAL X-OVER/SUBWOOFER DIRECT
This switch allows the internal crossover circuitry to be removed from the signal path. This is
required in certain installations which route the signal through external processors with a
crossover circuit of their own, such as the new digital units. Simply move the switch to
SUBWOOFER DIRECT to disengage the built-in crossover. For all other installations which do
not have a separate electronic crossover, we recommend you leave the switch set to
INTERNAL X-OVER to provide optimum performance.

A u t o Tu r n o n F u n c t i o n
With this function in the “auto” position, your subwoofer can be safely left with the main power
switched on continuously. The subwoofer will turn itself on automatically when an audio signal
is present. If no signal is present for approximately 10 minutes, the unit will switch to standby
mode. While in standby mode, your subwoofer will draw very minimal power. This function can
be disabled by leaving the switch in the “on” position.
Power Switch
The master power switch is located on the lower half of the unit. This rocker style switch is the
main on/off for the unit. This switch should be set to position 1 (up) for on, and 0 (down) for
off. If the unit is to be left unused for an extended period of time, the master power switch
should be turned off.
Subwoofer Outputs
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 filtered and designed to be used with a conventional amplifier 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
X-OVER/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 built-in crossover for
optimal performance.
LINE-LEVEL CONNECTION - OPTION A
Figure 1 shows connection from your home theater receiver to the LFE input on the back of
your subwoofer. When the subwoofer is installed in this fashion, all of the low frequency
information from your “LFE Out” or “Subwoofer Out” on the back of your receiver will pass into
your Velodyne subwoofer. This connection is the most common connection method when using
your subwoofer with a 5.1 receiver. (Cable needed: 1 mono RCA cable.)

Figure 1. Installation Using LFE Line-Level Inputs
Note: If not using an external crossover, you should use the built-in crossover for
optimal performance. When using a single channel input (such as a surround sound
processor’s subwoofer out or LFE), the auto on/off circuit sensitivity will be affected.
When one input channel is used instead of two, the unit will see lower signal levels
present at the inputs. This may cause the unit to turn off when listening at low volume
levels. If this occurs, simply use a “Y” adapter (available from most dealers) to allow
your processor’s single sub line to be fed into both L&R inputs. This will make the unit
turn on at lower signal levels.

LINE-LEVEL CONNECTION - OPTION B
Figure 2 shows connection from a pre-amplifier’s main outputs to the left and right inputs of
your Velodyne subwoofer. You will also need to connect a second pair of RCA cables from the
outputs on the back of your subwoofer to the inputs on the back of your amplifier. When the
subwoofer is installed in this fashion, your satellite speakers will be crossed over at 80 Hz which
removes the lower bass frequencies from your external amplifier and speakers, enabling them
to do a better job reproducing the higher frequencies. By utilizing this method, you will have a
bi-amplified system, gaining improved power and headroom for your system. This installation
method is not as common as the method described in Figure 1. (Cables needed: 2 stereo pair
of RCA cables.)

Speaker-Level Connections
Figure 3 shows an easy way to connect your Velodyne subwoofer directly to your receiver or
integrated amplifier, if it lacks line-level outputs. You may also connect your satellites directly to
your receiver or amplifier along with the subwoofer. Your receiver or amplifier will not notice the
additional load of the subwoofer due to the high input impedance.
Figure 3. Installation Using Speaker-Level Inputs
Caution!!! To avoid 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.

Subwoofer Outputs
The Velodyne subwoofer is designed to operate using the full range audio signal for input when
using the built-in crossover. Many home theater processors/receivers (Dolby Digital®, DTS®,
THX™) have a “subwoofer out” jack that is internally filtered and designed to be used with a
powered subwoofer. In these installations, you may bypass the internal crossover in either the
processor or the Velodyne subwoofer. In some installations, it may be beneficial to have a
steeper ultimate crossover slope. 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 sub,
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 crossover, simply locate the switch marked INTERNAL X-OVER/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.
Interconnect Cables
When installing your new Velodyne subwoofer using the line level connections, you should always
use shielded phono cables. There are many decent cables available today, most any of which
will work perfectly well. We do recommend that you keep 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. Be very careful to avoid any loose strands or frayed wires which may result in
a short, which may damage your equipment. 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.

C a r e o f Yo u r S u b w o o f e r
Your Velodyne subwoofer does not require any regular maintenance. Normal dusting or cleaning
of the surface for appearance purposes are all that is required. We suggest you avoid any harsh
detergents or chemicals when cleaning the cabinet. Abrasives, detergents, or cleaning
solutions may damage the finish on the cabinet. We recommend using only 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.
Protection Circuitry
Your new subwoofer is equipped with special protection circuitry to provide maximum
performance with greatest reliability.
The unit is protected against:
1) Overdriving the speaker or amplifier
2) Overheating the amplifier
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. In some extreme situations
(sustained high output levels such as pro sound usage), the unit may shut down momentarily.
This indicates the thermal or under-voltage protection circuitry has engaged. If this should
happen, you should reduce the volume setting or shut the unit off until normal operating
conditions return. You may also want to plug the unit into a different wall outlet, as dropping
power line voltage will be most noticeable under strenuous conditions and may result in the unit
shutting down intermittently.

T roubleshooting and Service
Before seeking service for your amplifier or subwoofer, please re-check all systems. Following
is a simple troubleshooting guide to assist you.
1.
2.
3.
4.
5.
Verify that the unit is plugged in and power outlet used is active.
Is the power switch on?
Is the unit receiving an input signal from your source?
Have all controls (volume, crossover, phase, etc.) been properly set?
If the unit has been running at high levels, one of the protection circuits may be engaged.
Has the amplifier overheated?
6. Make sure binding posts are tightened.
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 should return upon cooling, but you may be required to turn the power off and then
on again to reset the unit.
The following conditions require service by a qualified technician:
1. The power cord has become damaged
2. The unit does not appear to operate normally or exhibits a marked
change in performance
3. The unit has been exposed to water
4. Some part of the chassis or circuitry is physically damaged
