Velodyne Acoustics FSX-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 clean, full, and extended quality of the F-1800R's bass caused me
to gasp with the recognition that I was finally listening to a real subwoofer."

"... our entire listening room swelled with solid, satisfying bass, as if both
musician and instrument were in the room."

"...scenes such as the pre-battle sequence in Braveheart ... may very well
have threatened the room's structural integrity had we not backed off the
volume a bit..."

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." "Attention: Pour eviter
les chocs electriques, introduire lame la plus large de la fiche dans la borne correspondante de la prise et
pousser jusqu' au fond."

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.

All other servicing should be referred to qualified service personnel.

Troubleshooting & 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 and power outlet used is active.

2. Is power switch on?

3. Is auto turn on/off set properly?

4. Is unit receiving an input signal from your source?

5. Have all controls on subwoofer (volume, crossover, phase, etc.) been properly set?

6. Is the mute on the remote control engaged?

7. Are both volume controls properly set?

8. If unit has been running at high levels for an extended period of time, one of the
protection circuits may be engaged.

•Has the built-in amplifier overheated?

•Is your power line voltage sagging under heavy use?

If the protection circuitry is active, the unit may cycle on and off until operating parameters
return to normal. Protection circuit operation is usually indicated by a blinking power led.
Under more serious conditions, the unit may shut off completely. 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 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.

4. Some part of the cabinet or circuitry is physically damaged.
