The first type of protection circuitry which prevents overdriving of the speaker or amplifier operates constantly without being audible under most situations. In some extreme situations (sustained high output levels such as pro sound usage), the unit may shut down momentarily. This indicates operation of the thermal or undervoltage protection circuitry. If this should happen, you should reduce the volume setting or shut the unit off until normal operating conditions return. You may also want to plug the unit into a different wall outlet, as dropping power line voltage will be most noticeable under strenuous conditions.

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. When using speaker level connections, use a decent quality speaker cable that mates well with the connectors. Be very careful to avoid any loose strands or frayed wires which may result in a short, which may damage your equipment. Cables of extremely large size are typically not required. Extremely large gauge wire may not properly fit in the binding posts, resulting in a poor connection and possible short circuits.

Care of Your Subwoofer

Your Velodyne subwoofer does not require any regular maintenance. Normal dusting or cleaning of the surface for appearance purposes are all that is required. We do suggest you avoid any harsh detergents or chemicals when cleaning the cabinet. Abrasives, detergents, or cleaning solutions may damage the finish on the cabinet. We recommend using only 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 turn off the master power switch on the rear panel.

Protection Circuitry

Your new subwoofer is equipped with special protection circuitry to provide maximum performance with greatest reliability. The unit is protected against: 1) Overdriving the speaker or amplifier. 2) Overheating the amplifier. 3) Excessive drop in power line voltage.

Prepare for 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 for your system. Remember to perform all installation procedures with system power turned off to prevent possible damage.

Placement

True subwoofers operate at extremely low frequencies which are primarily omni-directional. While it is recommended that the subwoofer be placed on the same plane as the satellite speakers, room and system conditions often dictate otherwise. Keep in mind that frequency response and output level can be drastically influenced by placement, depending on the acoustic properties of the listening room. Typically, the optimum location for a subwoofer is tucked away in a corner of your listening room. This location will usually offer the greatest output levels and optimum low frequency extension. 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 by the satellite of the same channel.

Line-level Connection
Figure 1 shows connection to a pre-amplifier's main outputs and returning them to your amplifier inputs. When installed in this fashion, your satellite speakers will be crossed over at 80Hz which removes the lower bass from your amplifier and speakers, enabling them to do a better job reproducing high frequencies. By utilizing this method, you will have a bi-amplified system, gaining improved power and headroom for your system. 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. In some rare cases, combining both an external crossover and the one internal to the subwoofer may result in low output and increased noise. In these installations you may need to bypass the internal crossover in either the processor or Velodyne subwoofer. In some installations, simply setting one crossover to a higher frequency (such as 120 Hz) will restore maximum performance. To bypass the subwoofer's internal crossover when the unit is being fed a low pass signal from another crossover, simply locate the switch marked DIRECT/INTERNAL X-OVER on the rear panel of the subwoofer and set to the DIRECT position. This will eliminate the internal crossover from the signal path. Note: If not using an external crossover, you should use the built-in crossover for optimal performance.

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 cord should be routed in such a way that it will not be walked on, pinched, or compressed in any way that could result in damaging the insulation or wire. 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. This greatly increases flexibility when placing the unit close to video monitors as there is very little stray magnetism. Certain types of televisions are particularly sensitive to stray magnetic fields. If your television produces distorted colors after installing your subwoofer, simply increase the distance between your television and the subwoofer, until normal color and operation is returned. Your new Velodyne subwoofer, like any good speaker system, requires proper positioning within the listening space to provide maximum performance. Improperly placed speakers may degrade the sound quality and reduce your listening pleasure. Depending on the size and type of furnishings in the room, perfect placement may not be possible. Finding the best location for 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.

Speaker-level Connection

Figure 2 shows an easy way to connect your Velodyne subwoofer directly to your receiver or integrated amplifier, if it lacks line-level outputs. You may also connect your satellites directly to your receiver or amplifier along with the subwoofer if you wish. Caution!!! To avoid damage to your main amplifier, be sure to maintain correct polarity when making all connections. Red (positive) to red, and black (negative) to black. Be sure that all connections are tight, and that there are no loose strands or frayed wires.

Installation

Inputs Your new subwoofer is equipped with speaker-level and line-level 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, integrated amplifier, or receiver. Your amplifier section will notice no additional loading effects when you use these inputs due to their very high impedance.
Important!!! Do not use both LINE LEVEL and SPEAKER LEVEL connections simultaneously! Volume control This control allows you to balance the output from the subwoofer to the main speakers/amplifier in your system. This control should be set to achieve similar output level from both the main speakers and subwoofer when listening to music. A good starting point for the volume control is 3 or 4 dots from minimum. Low-pass crossover - 40 to 120Hz All inputs sum the left and right channels together, with the resulting signal passing through an adjustable low-pass crossover before being amplified. The crossover control allows you to adjust the upper limit of the subwoofer's frequency response from 40 to 120Hz. The subwoofer's response will begin rolling off above the frequency you set this control to. You should set the crossover frequency to obtain a smooth and seamless transition from the subwoofer to the main speakers in your system. If your main speakers are smaller units with limited low frequency output, you may wish to choose a higher frequency (such as 100-120Hz) than you would with larger speakers which have greater low frequency output. With larger speakers, you might start with this control set lower, such as 80Hz. 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 This control allows you the "reverse" the phase of the subwoofer's output signal 180 to correct for any possible mismatch and resulting cancellation between the subwoofer and your main speakers/amplifier. To adjust, simply listen to the system with music playing. Then move the switch from one position to the other and listen for a change in low frequency output. The correct position will have a greater amount of apparent low frequency output. Crossover switch - DIRECT/INTERNAL X-OVER This switch allows the electronic crossover circuitry to be removed from the signal path. This is required in certain installations which route the signal through external processors with a crossover circuit of their own, such as the new digital units. Simply move the switch to DIRECT to

disengage the built in crossover. For all other installations which do not have a separate electronic crossover, we recommend you leave the internal crossover INTERNAL X-OVER to provide optimum performance. Auto turn on function With this function in the "auto" position, your subwoofer can be safely left with the main power switch on continuously. The subwoofer will turn itself on automatically when an audio signal is present. If no signal is present for approximately 7 minutes, the unit will switch to standby mode. While in standby mode, your subwoofer will draw very minimal power. This function can be disabled by leaving the switch in the "on" position. Power switch The master power switch is located on the lower half of the unit. This rocker style switch is the main on/off for the unit. This switch should be set to position 1 (up) for on, and 0 (down) for off. If the unit is to be left unused for an extended period of time, the master power switch should be turned off. 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. In some rare cases, combining both an external crossover and the one internal to the subwoofer may result in low output and increased noise. In these installations you may need to bypass the internal crossover in either the processor or Velodyne subwoofer. In some installations, simply setting one crossover to a higher frequency (such as 120 Hz) will restore maximum performance. To bypass the subwoofer's internal crossover when the unit is being fed a low pass signal from another crossover, simply locate the switch marked DIRECT/INTERNAL X-OVER on the rear panel of the subwoofer and set to the DIRECT position. This will eliminate the internal crossover from the signal path. Note: If not using an external crossover, you should use the built-in crossover for optimal performance.

Prepare for Installation

Your new Front Row System provides for a number of installation options, especially when combined with a Velodyne subwoofer. 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 to prevent possible damage.

Interconnect Cables

When installing your new Velodyne speaker system with a subwoofer using the line level connections, you should always use shielded phono cables. There are many cables available today, 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. For speaker level connections, use a 16-gauge or larger speaker cable that mates well with the connectors. Be very careful to avoid any loose strands or frayed wires which may result in a short, causing damage to your equipment. Cables of extremely large size are typically not required. Oversize wire may not properly fit in the binding posts, resulting in a poor connection and possible short circuits.

Placement

Your new Velodyne speaker system, like any good speaker system, requires proper positioning within the listening space to provide maximum performance. Improperly placed speakers may degrade the sound quality and reduce your listening pleasure. Depending on the size and type of furnishings in the room, perfect placement may not be possible. Finding the best location for your environment will likely require some experimentation. We suggest observing the following guidelines, then experiment with the location during setup to find what sounds best to you when seated in your typical listening position. While the optimum location for a subwoofer (typically) is tucked away in a corner of your listening room, the front Left, Center, and Right satellite speakers should be placed so the speakers are at the same height as your ears when seated in your typical listening spot. The center speaker will typically be placed above or below the TV in the direct center of the screen. The left and right front speakers should be placed at equal distance from the center and close to the same height and close to the height of your ears when seated (Figure 1). The rear surround speakers are not as critical of placement and should be placed behind the listeners. Mount the rear speakers slightly above listeners ears. They may be aimed straight ahead, or angled inward toward the listener.
Care of your speaker system
Your Velodyne speaker system does not require any regular maintenance. Normal dusting or cleaning of the surface for appearance purposes are all that is required. We do suggest you avoid any harsh detergents or chemicals when cleaning the cabinet. Abrasives, detergents, or cleaning solutions may damage the finish on the cabinet. We recommend using only a damp cloth to clean the cabinet.
Find your space Select an area of the room which gives you an unobstructed line of sight to the speakers. Achieve proper tonal response Your speakers will perform best when they are placed at least 1-2 feet from any back or side walls. Speaker height In the front, speakers should be close, if not equal to the height of the listeners ears.
Connection Thru Subwoofer (line-level)
Figure 4 illustrates how to connect your new satellite speakers through your Velodyne subwoofer's line level crossover. This is only possible if your receiver has in/out loop connections that separate the amp and preamp stages. Consult the manual for your receiver for further information on this capability. This will remove the lower bass from your front satellite speakers only. Other speakers will still receive full range information. This method should only be used if your receiver does not have high pass crossover functions built into the surround sound processor. Figure 4. Connecting thru Velodyne subwoofer's line level high pass crossover

q Speaker separation

The distance between the speakers will have a considerable effect on the stereo image and apparent placement of sound. A good rule of thumb for most listening rooms is to have the left and right speakers between 6-9 feet apart. q Fine tune position (up/down) If the speakers are at a different height than the listener, it may be beneficial to tilt the speakers up or down to aim them more directly at the listening area. Fine tune position (left/right) Once general position of the speakers is selected, adjust the angle of the speakers. In some installations you may need to "toe in" the speakers to aim them at the listeners. Tone control adjustment These speakers are designed to provide a very smooth and accurate frequency response, in most rooms, without any extra equalization. This makes adjusting the tone controls (bass/treble) unnecessary in most installations. Room furnishings The type and location of furnishings in your room may greatly affect the sound you hear. Rooms with hardwood floors and minimal upholstered surfaces may sound very bright and live from an extra amount of reflected sound. Other rooms with heavily padded floors and carpeting, along with thick drape tend to make the sound warm and softer. Keep this in mind when setting up your audio/video listening room.

Connection Direct From Receiver
Figure 2 illustrates how to connect your Velodyne speaker system directly to your receiver or amplifier. This is the preferred connection method for most systems that have a "subwoofer out" connection and electronic filter as part of the surround sound processor. It is recommended that you activate your receiver/processor's high pass filter function. We recommend setting this crossover in your receiver or processor to 80 Hz. To do this, select "small" mode on the speaker setup menu of your receiver. This is nominal for most systems and will allow your satellite speakers to go reasonably low and provide good imaging while allowing your sub to blend in perfectly. The higher the crossover frequency between your speakers and subwoofer, the easier it will be to locate sound from the subwoofer. This is undesirable, as it will degrade the imaging of your system. If your equipment does not have the required outputs for this type of installation, consult the following two installation methods for more options. If none of the methods shown will work in your system, or if you should have further questions, please consult your dealer or call our technical support department for more help. Figure 2. Connections direct from power amp/receiver with electronic crossover

Connection Thru Subwoofer (speaker-level)
Figure 3 illustrates how to connect your new satellite speakers through your Velodyne subwoofer's speaker level crossover. This will remove the lower bass from your front satellite speakers only. Other speakers will still receive full range information. This method should only be used if your receiver does not have high pass crossover functions built into the surround sound processor. Be careful to connect the positive + (red) terminals on your receiver to the + (red) terminals of your subwoofer. Reversing these connections may damage your subwoofer.
