Velodyne VX-10 - Manual (Page 14)

Regardless of where you install your Velodyne subwoofer, it must remain
in an upright position (woofer facing forward). Using, shipping, or
otherwise storing the subwoofer in any other position for an extended
period of time may result in damage to the unit not covered by warranty.
The VX-10 is magnetically shielded to reduce the amount of stray magnetic
energy emitted from the speaker's motor structure. This greatly increases
flexibility when placing the unit close to video monitors as there is very little
stray magnetism. Certain types of televisions are particularly sensitive to
stray magnetic fields. If your television produces distorted colors after
installing your subwoofer, simply increase the distance between your
television and the subwoofer, until normal color and operation is returned.
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 for 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.
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.
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 levels from both the main speakers and subwoofer
when listening to music. A good starting point for the volume control is
2 or 3 dots from minimum.

Protection Circuitry
Your new subwoofer is equipped with circuitry to provide maximum
performance with greatest reliability.
The unit is protected against:
1) Overheating the amplifier.
2) Excessive drop in power line voltage.
If either of the above 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.
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.
1. Verify unit is plugged in, power outlet used is active, and supplying
proper voltage.
2. Is power switch on? (230V model)
3. Is unit receiving an input signal from your source?
4. Have all controls on subwoofer (volume, crossover, phase, etc.) been
properly set?
5. 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?
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.
