Troubleshooting and Service
Before seeking service for your Front Row Speaker System, please check
all the components in your system for proper operation. Following is a
simple troubleshooting guide to assist you.
1. Verify speakers are properly connected to receiver/amplifier and that
electronics are switched on and functioning properly.
2. Is the speaker selector switch of the receiver in the proper position?
3. Are all speaker cables in good condition and making good contact with
all terminals?
4. Is your receiver getting a signal from your source device?
5. Is your receiver sending a signal to the speakers?
6. If speakers have been running at high levels, the protection circuit may
be engaged which reduces volume for a short period of time. First, reduce
the volume setting of your equipment. The volume should return to
normal after a few moments.
The following conditions require service by a qualified technician:
1. The enclosure has become damaged or broken.
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 speaker (woofer or tweeter) is physically damaged.
Thank you for purchasing a Velodyne!
Congratulations!
Congratulations on your purchase of the CHT Front Row System. This
system represents the state of the art in home audio reproduction and will
provide you with years of listening pleasure when properly used and cared
for. Read and follow this instruction manual to insure safe and proper
system connection and operation.
This speaker system was designed to offer seamless integration with any
of our CHT Series subwoofers. It is essential that you use a Velodyne
subwoofer with the CHT Front Row System to achieve optimal performance.
The addition of a Velodyne Subwoofer will allow your loudspeaker system
to reproduce the bass frequencies from approximately 80Hz and below.
With the CHT Front Row System and a Velodyne subwoofer, working
together as a system, the sound quality, output levels, and value will exceed
most other systems.
Please unpack the system carefully. Remove all staples used to seal the
carton as they can scratch the cabinets. Please save the carton and allpackaging materials for future use. Record the serial number in the space
provided on the warranty card for future reference.

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.
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.
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.
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.

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.

●●
●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.
●●
●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 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.
