Congratulations!
–––––––––––––––––––––––––––––––––––––––––––––––—————–
Congratulations on your purchase of a Velodyne subwoofer system. This system
represents the absolute state of the art in accurate low frequency reproduction. We
believe this to be one of the finest subwoofers available anywhere! In this new
subwoofer, we have combined our radical new driver & amplifier designs to obtain
our traditionally accurate sound while increasing efficiency and output to new
standards. This exceptional subwoofer will provide you with years of unparalleled
listening pleasure. Enjoy!
Caution!
––––––––––––––––––––––––––––––––––––––––––––––––—————
Please observe the following instructions to insure safe and proper system
operation.
Warning!
To prevent fire or shock hazard, do not expose this equipment to rain or moisture.

conventional non-servo systems. While the input signal is being sent to the amplifier which
powers the driver, a continuous signal representing cone motion is being sent to a
comparator circuit. This circuit constantly adjusts for any deviation between the input
signal and the subwoofer's output. This self regulation results in extreme control over cone
movement, and very accurate low distortion sound.
To provide the power for driving this massive loudspeaker, we incorporated an extremely
efficient Class D switching amplifier. This new amplifier features our patent pending energy
recovery circuit design which drastically reduces wasted energy (heat) as compared to
traditional switching designs. One that is capable of running cool to the touch and
providing 1000 or 1250 watts (RMS - depending on the model) of power! At typical listening
levels, the HGS produces less than 1% harmonic distortion with input signals extending to
20Hz. At higher levels the distortion barely exceeds 1%, far better than any conventional
design currently on the market. This combination provides you with the best combination
of clean, deep, accurate bass, without making any sacrifice to distortion.
Care of your subwoofer
––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
Do not use any harsh detergents or chemicals to clean the cabinet. Abrasives, detergents,
or cleaning solutions may damage the finish on the cabinet. We recommend using a damp
cloth to clean the cabinet. During normal conditions, your new subwoofer may be left on
continuously without any problems. The unit is equipped with a signal-sensing turn on/off
that will automatically turn on the unit when a signal is present at the inputs and turn off
the unit after several minutes when there is no longer any signal at the inputs. If you plan
to leave the subwoofer unused for an extended period of time, we recommend that you
unplug the unit.
