PREPARE FOR INSTALLATION  
Thank You for Purchasing a SPL-800i Subwoofer!  
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.  
LIMITED WARRANTY  
VELODYNE ACOUSTICS, Inc. (“VELODYNE”) warrants all powered subwoofers  
for a period of two years and full range speakers for a period of five years. All  
VELODYNE products have a warranty from the date of purchase against defects  
in materials and workmanship subject to the following conditions:  
PLACEMENT  
1. VELODYNE is not responsible for defects which result from the use of an  
amplifier or controller other than the one originally supplied with the unit  
(subwoofer) or defects which result from modifications or repairs made by any  
component of the system by anyone other than a VELODYNE factory  
authorized service representative.  
2. This warranty is void if any repairs or service covered by the terms of this  
warranty are made to any component of the system by anyone other than a  
VELODYNE factory authorized service representative.  
3. VELODYNE is not responsible for damage caused by accidents, abuse,  
misuse, natural or personal disaster or unauthorized modification. The  
VELODYNE products are not intended for professional or commercial use and  
VELODYNE is not responsible for damage resulting from such use.  
4. The VELODYNE product warranty is limited to units that are purchased  
from authorized VELODYNE dealers and finalized within authorized  
dealer locations.  
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.  
5. This warranty is nontransferable under any condition.  
TO OBTAIN SERVICE  
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.  
Information regarding service may be obtained from the dealer from whom you  
purchased the unit, or by contacting VELODYNE customer service. Warranty  
service must be performed by a VELODYNE factory authorized service  
representative within the warranty period set forth above. If VELODYNE  
determines the unit is defective, VELODYNE will, at VELODYNE’s option, repair  
or replace the product at no charge if the product is forwarded prepaid to a factory  
authorized service representative. Products forwarded to the factory authorized  
service representative should be shipped securely and properly packaged,  
insured and freight prepaid.  
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.

SPL-800i SPECIFICATIONS  
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.

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.

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

TROUBLESHOOTING AND SERVICE  
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.  
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!  
1. Verify that the unit is plugged in, power outlet used is active and  
supplying proper voltage.  
2. Is the power switch on?  
3. Is the auto turn on/off set properly?  
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.  
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?  
Crossover Switch - INTERNAL X-OVER/  
SUBWOOFER DIRECT  
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.  
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.  
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  
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.  
4. Some part of the cabinet or circuitry is physically damaged  
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 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.  
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.  
NOTE: If not using an external crossover, you should use the built-  
in crossover for optimal performance.  
P
INTERCONNECT CABLES  
P
LINE-LEVEL CONNECTION – OPTION A  
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.  
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.)  
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.  
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.  
P
CARE OF YOUR SUBWOOFER  
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.  
12  
5
 
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.

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.

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.)
