Page 7: Installation
Installation Your new Velodyne servo subwoofer provides for a number of installation options. Read all the installation information below in order to determine which installation option is best for your system. Remember to perform all installation procedures with system power turned off!!! Inputs Your new subwoofer is equipped with speaker-level, line-level and balanced (XLR) inputs. - Page 8 A bypass switch is also provided if you wish to use an external crossover. If you are not using an external crossover, we recommend that you use the one provided within the unit for optimum performance! Phase adjustment - 0° 180°...

Page 9: Line-Level Connection
External remote jack This connection allows an auxiliary infrared remote receiver "eye" to be installed and placed where most convenient. This option is usually only required when the subwoofer is to be part of a custom installation in which the built in "eye" (located adjacent to the speaker on the front baffle) will be hidden in a location where it can not adequately receive signals from the remote. - Page 10 Figure 1: Installation Using Line-Level Inputs PRE-AMP MAIN OUTPUTS LEFT RIGHT Subwoofer outputs The Velodyne subwoofer is designed to operate using the full range audio signal for input when using the built-in crossover. Some processors/receivers, have a "subwoofer out" jack that is internally filtered and designed to be used with a conventional amplifier and speaker.

Page 11: Speaker-Level Connection
Speaker-Level Connection Figure 2 shows an easy way to connect your Velodyne subwoofer directly to your receiver or integrated amplifier. When connected in this fashion, your satellite speakers will be crossed over at 80/100Hz, which removes the lower bass from your speakers, enabling them to do a better job reproducing high frequencies. -
Page 12: Interconnect Cables
Interconnect Cables When installing your new Velodyne subwoofer using the line level connections, you should always use shielded phono cables. There are many decent cables available today, most any of which will work perfectly well. We do recommend that you keep the length of cable as short as possible to avoid any potential noise problems. -
Page 13: Protection Circuitry
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 subwoofer is magnetically shielded to reduce the amount of stray magnetic energy emitted from the speaker's motor structure. -
Page 14: Distortion In Loudspeakers
Distortion in Loudspeakers Nonlinear distortion is a problem which plagues all speakers. This particular type of distortion is a common problem in subwoofers, which must move large amounts of air to produce adequate levels of deep bass. Nonlinear distortion is defined as any form of distortion that moves energy from one portion of the audio frequency spectrum to another. - Page 15 We determined that conventional motors are unacceptable when called upon to produce the amount of linear motion we desired. This inadequacy led us to design an improved motor structure by incorporating two coils, operating out of phase in a push-pull configuration within two magnetic gaps and suspended by dual spiders for even greater linearity.
