Velodyne Acoustics HGS 10, HGS 12 User Manual

"If you know subwoofers, you know about Velodyne."

-Corey Greenberg
Home Theater Technology/February 1995
Face Off: Comparison of five subwoofers

"...the HGS-10 can be used in settings where a larger, more conventional
subwoofer would be unacceptable. In addition, its performance is good
enough that it's worth considering even if space is not an issue. Just be
prepared to watch your friends' jaws drop when you tell them the bass
they're hearing is coming from that little box."

-Robert Deutsch
Stereophile Guide to Home Theater/September 1998

"In general, the Velodyne (HGS-12) could play slightly louder, and often
cleaner, than the Sunfire."

"The Velodyne HGS-12 was an excellent performer whose output and bass
extension were competitive with those of much larger subwoofers. With its
compact size, sturdiness, good looks, and low distortion, it warrants serious
consideration."

IMPORTANT SAFETY INSTRUCTIONS

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

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 lighting 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 subwoofer is operated.

2. Retain Instructions -- The safety and operating instructions should be retained for future reference.

3. Heed Warnings -- All warnings on the subwoofer 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 subwoofer 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 subwoofer should be used only with a cart or stand recommended by the manufacturer.

7. Wall or Ceiling Mounting -- The subwoofer should be mounted to a wall or ceiling only as recommended by
the manufacturer.

8. Ventilation -- The subwoofer should be situated so that its location or position does not interfere with its proper
ventilation. For example, the subwoofer 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 subwoofer should be situated away from heat sources such as radiators, heat registers, stoves,
or other subwoofers that produce heat.

10. Power Sources -- The subwoofer should be connected to a power supply only of the type described in the
operating instructions or as marked on the subwoofer.

11. 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 subwoofer.

12. Caution: To prevent electrical shock, match wide blade of plug to wide slot, fully inserted.

13. Cleaning -- The subwoofer should be cleaned only as recommended by the manufacturer.

14. Nonuse Periods -- The power cord of the subwoofer 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 subwoofer 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 subwoofer.
c. The subwoofer has been exposed to rain.
d. The subwoofer does not appear to operate normally or exhibits a marked change in performance.
e. The subwoofer has been dropped or damaged.

17. Servicing -- The user should not attempt to service the subwoofer beyond what is described in the operating
instructions.

18. Overloading - Do not overload wall outlets, extension cords, or integral convenience receptacles as this can
result in a risk of fire or electric shock.

19. Replacement parts - When replacement parts are required, be sure the service technician has used
replacement parts specified by the manufacturer or have the same characteristics as the original part.
Unauthorized substitutions may result in fire, electric shock, or other hazards.

20. Safety Check - Upon completion of any service or service of repairs to this product, ask the service technician
to perform safety checks to determine that the product is in proper operating condition.

All other servicing should be referred to qualified service personnel.
