"If you know sub woofers, you know about Veladyne ."
"... it's safe to say that when it comes to woofin , done right ,
Velodyne 's bigger models are probably the safe st bet there is."
"... we just sat there marvelling at the sheer power and majesty of
this jun ior varsity Velodyne."

Troubleshooting & Service
Before seeking service fo r your VA-8 10/1 012 XII subwoofer, please
re-check all systems. Following is a simple troubleshooting guide to
assist you.
1.
2.
3.
4.
5.
Verify unit is plugged in and power outlet used is active.
Is power switch on?
Is auto turn on/off set properly?
Is unit receiving an input signal from your source?
Have all controls on subwoofer (volume, crossover, phase,
etc.) been properly set?
6. If unit has been running at high levels, one of the protection
circuits may be engaged.
Has the built-in amplifier overheated?
Has the speaker's voice coil started to heat up?
If the protection circuitry is active, the unit may cycle on and off until
operating parameters return to normal. Under more serious condi
tions , the unit may shut off comp)etely. Normal operation will return
upon cooling, but you may be required to turn the power off and then
on again to reset the unit.
The follo w ing conditions require service by a qualified technician :
1. The po wer cord has become damaged.
2. The unit does not appear to operate normally or exhibits a
ma rked change in performance.
3. The unit has been exposed to water.
4 . So me part of the cabinet or ci rcuitry is physically damaged.
Thank you for purchasing a Velodyne!

Installation
Your new VA-810/ 10 12XII subwoofer system provides for a number
of installation options. Read all the installation information below in
order to determine which installation opt ion is best for your system.
Remember to perform all installation proc edures with system
powe r turned off.
Inputs
Your new VA-810/ 1012 XII subwoofer is equipped with both speaker
level and line-level inputs. Use the LINE- IN jacks when connecting
your subwoofer to a pre -amp, signal processor, or line-level cross
over. The FROM AM PLIFIER jacks connect directly to the speaker
outputs of a integrated amplifier or receiver. Your amplifier section
will notice no additional loading effects when you use these inputs
because of their high impedance.
Note
00 not use both LINE-IN and FROM AMPLIFIER inp uts simulta
neously.
Volume cont rol
This control allows you to balance the output from the sub woofer to
the main speakers in your system . This contr.olshould be set to
achieve similar vol ume level from both the ma in speakers and
subwoofer.
same channel.
Keep in mind that freq uency response and output level carl be
drastically influenced by placement depending on the acoustic
properties of the listening room . Ty pically the VA-810/1012XII will
sound louder when placed next to a wall or in a corner.
Cautio n!
The VA series sub woofers have amplifiers built into the cabinet. 0 0
not place the cabinet next to sources of heat such as furnace
registers, radiators, etc. The power cord sh ould be routed in 'Such
a way that it will not be walked on, pinched, or compressed in any
way.
Regardless of where you install your VA-81 0/1012 XII subwoofer, it
must remain in an upright position (passive radiat or facing down
ward) . Using, shipping , or otherwise storing the VA-810 /101 2XII
subwoofer in any other position for an extended pe riod of time may
result in damage to the unit not covered by warranty.
The VA-810/10 12XII Subwoofer is magnetically shielded to reduce
magnetic emission from its cabinet to increase the number of
possibl e locations available for placement. However, this shielding
may not be adequate for all installations. Certain types of televisions
are particularly sensitive to stray magnetic fields . If your television
produces distorted colors after installation of your VA-81 0/1 012XII
subwoofer, simply increase the distance between your television
and the VA-81 0/1012 XII until normal color and operation is re
turned.
ooter
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. T he subwoofer's response will beg in rolling off above the
frequency you set this control to.
Do not use any harsh detergents or chemicals to clean the cabinet.
Abrasives, detergents, or clean ing solutions may damage the finish
on the cabinet. We recommend using a damp cloth to clean the
cabinet.
You should set the crossove r frequency to obtain a smooth and
seamless transition from the subwoofer to the mai n speakers in
your system. If your main speakers are sma ller units with limited low

one internal to the subwoofer may result in low output and increased
noise. In these cases, to optimize your subwoof er performance you
should bypass the inte rnal crossover in your Velodyne subwoofer .
To bypass the crossover within the subwoofer , simply locate the
switch marked "out / in" on the back panel of the subwoofer and set
to the "out" position. This will eliminate the internal crossover func
tion.
Note
If not using an external crossover, you should use the built-in

A word about subwoofer outputs
The Velody ne subwoofer is designed to opera te using the full range
audio sign al for input when using the built-in crossover. Some
surround sound processors/receivers, including the Dolby AC3
system with their .1 channel output, have a "subwoofer out"jack that
is already crossed ove r and designed to be used with a conventional
Whe n connected in this fashion, your satellite speakers will be
crossed over at 80/1OOhz, which removes the lower bass from your
speakers thus, enabling them to do a better job reproducing high
freque ncies.
You may also connect your satellites directly to your receiver or
amplifier along with the subwoofer if you wish to bypass the internal
high-pass crosso ver.
Caution !
To a void damage to your main amp lifier, be sure to maintain correct
pola rity when making all connectio ns. Red (positive) to red, andblack
(negative) to black. Be su re that all connections are tight, and that
there are no loose strands or frayed wires.
