IMPORTANT SAFETY INSTRUCTIONS
Caution
To reduce the risk of electric shock, do not remove cover (or back). No user-serviceable parts inside. Refer servicing to qualified service personnel.
The lightning flash with arrowhead symbol is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.
The exclamation point symbol is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the subwoofer.
1. Read Instructions — All safety and operating instructions should be read before the product is operated.
2. Retain Instructions — The safety and operating instructions should be retained for future reference.
3. Heed Warnings — All warnings on the product and in the operating instructions should be adhered to.
4. Follow Instructions — All operating and use instructions should be followed.
5. Water and Moisture — The product should not be used near water — for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, near a swimming pool or the like.
6. Carts and Stands — The product should be used only with a cart or stand recommended by the manufacturer.
7. Wall or Ceiling Mounting — The product should be mounted to a wall or ceiling only as recommended by the manufacturer.
8. Ventilation — The product should be situated so that its location or position does not interfere with its proper ventilation. For example, the product should not be situated on a bed, sofa, rug, or similar surface that may block the ventilation openings; or placed in a built-in installation such as a bookcase or cabinet that may impede the flow of air through the ventilation openings.
9. Heat — The product should be situated away from heat sources such as radiators, heat registers, stoves, or other products that produce heat.
10. Power Sources — The product should be connected to a power supply only of the type described in the operating instructions or as marked on the product.
11. Grounding or Polarization — This product may be equipped with a polarized alternating-current line plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug.
12. Power-Cord Protection — Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point at which they exit from the product.
13. Cleaning — The product should be cleaned only as recommended by the manufacturer.
14. Nonuse Periods — The power cord of the product should be unplugged from the outlet when left unused for a long period of time.
15. Object and Liquid Entry — Care should be taken so that objects do not fall and liquids are not spilled onto the enclosure.
16. Damage Requiring Service — The product should be serviced by qualified service personnel when: a. The power-supply cord or plug has been damaged. b. Objects have fallen or liquid has been spilled into the product. c. The product has been exposed to rain. d. The product does not appear to operate normally or exhibits a marked change in performance. e. The product has been dropped or damaged.
17. Servicing — The user should not attempt to service the product beyond what is described in the operating instructions. All other servicing should be referred to qualified service personnel.
18. Lightning — For added protection for the product during a lightning storm or when it is left unattended and unused for long periods of time, unplug it from the wall outlet.
19. Overloading — Do not overload wall outlets, extension cords or integral convenience receptacles as this can result in a risk of fire or electric shock.
20. Attachments — Only use attachments and accessories specified by the manufacturer.
21. Voltage — Insure that the subwoofer is only connected to the rated source voltage. Do not connect the 120-volt version to 230-volts or vice-versa. This will result in damage to the subwoofer and possible injury to the user.
CAUTION: To prevent electrical shock, match wide blade of plug to wide slot, fully inserted.

Placement of Your Subwoofer
The first step in installing your new MicroVee is to determine where it will be placed in the room. Unpack the system carefully and use the following guidelines in order to find the best room placement option.
True subwoofers operate at extremely low frequencies which are primarily omni-directional. Keep in mind that frequency response and output level can be drastically influenced by placement, depending on the acoustic properties of the listening room. To obtain optimum output from your subwoofer, place it within a foot of a corner. This location will offer the greatest output levels and optimum low frequency extension. If at all possible, your subwoofer should be placed along a wall. 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 near the satellite of the same channel.
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.
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.
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 cor compressed in any way that could result in damaging the insulation or wire.
d should be routed in such a way that it will not be walked on, pinched or

Installation
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
f to prevent possible damage.
of
Figure 1. MicroVee Back Panel
Important!!! Insure that the subwoofer is only connected to the rated source voltage. Do not connnect the 120-volt version to 230-volts or vice-versa. This will result in damage to the subwoofer and possible injury to the user.
Inputs
Your new subwoofer is equipped with speaker-level, line-level, and MINI-JACK 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 will notice no additional loading effects when you use these inputs due to their very high impedance. Use the MINI-JACK inputs when connecting to a docking station or personal audio system.
Important!!! Do not use any of the LINE LEVEL, SPEAKER LEVEL, and MINI-JACK connections simultaneously!
