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.  
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.  
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.  
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.  
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.  
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.  
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.  
Auto Turn on Function  
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.  
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

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  
SUBWOOFER  
VOLUME  
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.

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.)

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.

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.)

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.  
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.

SUBWOOFER OUTPUTS  
TM  
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.

WARNING: TO REDUCE THE RISK OF FIRE  
OR ELECTRIC SHOCK. DO NOT EXPOSE  
THIS APPLIANCE TO RAIN OR MOISTURE.  
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.

CARE OF YOUR SUBWOOFER  
TROUBLESHOOTING AND SERVICE  
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.  
If you should experience a problem with the operation of your subwoofer,  
please check all of the following before seeking service. Following is a  
simple troubleshooting guide to assist you.  
1. Verify that the unit is plugged in, power outlet used is active and  
supplying proper voltage.  
2. Is the power switch on?  
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.  
3. Is the auto turn on/off set properly?  
4. Is the unit receiving an input signal from your source?  
5. Have all controls on the subwoofer (volume, crossover, phase,  
etc.) been properly set?  
6. If unit has been running at high levels for an extended period of  
time, one of the protection circuits may be engaged.  
• Is the built-in amplifier extremely hot to the touch?  
• Is your power line voltage sagging below acceptable levels?  
PROTECTION CIRCUITRY  
Your new subwoofer is equipped with special protection circuitry to  
provide maximum performance with greatest reliability.  
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 unit is protected against:  
1) Overdriving the speaker or amplifier  
2) Overheating the amplifier  
The following conditions require service by a qualified technician:  
3) Excessive drop in power line voltage  
1. The power cord has become damaged  
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.  
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 cabinet or circuitry is physically damaged
