Prepare for Installation
YournewFrontRowSystemprovidesforanumberofinstallationoptions,
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
procedureswithsystempowerturnedofftopreventpossibledamage.
Placement
Your new Velodyne speaker system, like any good speaker system,
requiresproperpositioningwithinthelisteningspacetoprovidemaximum
performance.Improperly placedspeakers maydegrade 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
experimentwith thelocation duringsetup to find what sounds best toyou
when seated in your typical listening position.
While the optimum location for a subwoofer (typically) is tucked away
inacornerofyourlisteningroom,thefrontLeft,Center,andRightsatellite
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
typicallybeplacedaboveorbelowtheTVinthedirectcenterofthescreen.
The left and right front speakers should be placed at equal distance from
thecenterand closetothe sameheightand closetothe heightofyour 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
speakersslightlyabovelistenersears. Theymaybeaimedstraightahead,
or angled inward toward the listener.
●●
●●
●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.

using the line level connections, you should always use shielded phono
cables. There are many cables available today, any of which will work
perfectlywell. Wedorecommendthatyoukeepthelengthofcableasshort
as possible to avoid any potential noise problems.
Forspeakerlevelconnections,usea16-gaugeorlargerspeakercablethat

or frayed wires which may result in a short, causing damage to your
equipment. Cables of extremely large size are typically not required.

The distance between the speakers will have a considerable effect on the

listening rooms is to have the left and right speakers between 6-9 feet apart.

●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

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 pre-
ampstages. Consult the manual for your receiver for further information
onthiscapability. Thiswillremovethelowerbassfromyourfrontsatellite

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
electronicfilteraspartofthesurroundsoundprocessor. Itisrecommended
that you activate your receiver/processor's high pass filter function. We
recommendsetting this crossover in your receiver orprocessor to 80 Hz.
Todothis,select"small"modeonthespeakersetupmenuofyourreceiver.
Thisis nominal for most systemsand will allowyour 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. Ifyourequipmentdoesnothavetherequiredoutputsforthistype

options. Ifnoneof themethodsshown will workinyour system,orif you
