FEATURES
Stunning image quality through highly accurate signal processing
Our original three-dimension Y/C separation circuit has been employed together with the image processing circuit made
by Faroudja in the decoder section, the line doubler section, and the bandwidth expander section. Consistent signal
processing with high accuracy from input to output provides stunning image quality.
-
Line doubler section
Signals from the decoder section are progressively processed in the line doubler section. Faroudja's unique motion
algorithm rids jaggies and flickers from images by converting film images of 30 frames per second into 24 frames per
second and applying total still image processing. Reproduction through double the number of scanning lines realizes
natural progressive processing with higher accuracy and less missing information.
-
NTSC color decoder section
Faroudja's most reliable decoder for 10-bit processing and Analog Device's high performance AD converter jointly
offer highly accurate AD conversion. In addition, Faroudja's original chroma band expansion circuit provides film-like
images of high definition, greatly enhancing color transition, trangent and resolution.
-
Bandwidth expander section
In the bandwidth expander section, signals are refined to obtain higher image quality after the line doubling process-
ing. Bandwidth of Y (luminance) signal is doubled through the non-liner processing. Expanded bandwidth increases
image detail, improves trangent and enhances sharpness of images, achieving dramatic development in video image
quality and striking beauty and impression.
-
Y/C separation circuit section
Our original three-dimension filter correctly separates signals having motion images as well as signals having station-
ary images, considerably reducing cross-color and dot interference.
Selector function to connect 18 video sources at the maximum
Selectable inputs of three types, VIDEO IN, S-VIDEO IN and COMPONENT IN, allow 18 video sources at the maximum
to be connected depending on combination.
Various image quality adjustments
Various image quality adjustments, from basic adjustments of sharpness, contrast, etc. to advanced adjustments such as
black level extension adjustment, are available and offer a possible use as an equalizer. These adjustments can be
memorized in every program. Images are easily reproduced according to the preprogrammed adjustments just by switching
the programs depending on image materials.
The Faroudja name is the registered trademark of Faroudja, Inc. in the United States.

Do not use attachments not recommended by the prod-
uct manufacturer as they may cause hazards.
7
Water and Moisture

a bath tub, wash bowl, kitchen sink, laundry tub, in a
wet basement, or near a swimming pool, and the like.
8
Accessories
Do not place this product on an unstable cart, stand,
tripod, bracket, or table. The product may fall, causing
serious injury to a child or adult, and serious damage
to the product. Use only with a cart, stand, tripod,
bracket, or table recommended by the manufacturer,
or sold with the product. Any mounting of the product
should follow the manufacturer's instructions, and
should use a mounting accessory recommended by the
manufacturer.
9
A product and cart combination should be moved with
care. Quick stops, excessive force, and uneven sur-
faces may cause the product and cart combination to
overturn.
10 Ventilation
Slots and openings in the cabinet are provided for ven-
tilation and to ensure reliable operation of the product
and to protect it from overheating, and these openings
must not be blocked or covered. The openings should
never be blocked by placing the product on a bed, sofa,
rug, or other similar surface. This product should not
be placed in a built-in installation such as a bookcase
or rack unless proper ventilation is provided or the
manufacturer's instructions have been adhered to.
11 Power Sources
This product should be operated only from the type of
power source indicated on the marking label. If you
are not sure of the type of power supply to your home,
consult your product dealer or local power company.
For products intended to operate from battery power,
or other sources, refer to the operating instructions.
12 Grounding or Polarization
This product is equipped with a polarized alternating-
current line plug (a plug having one blade wider than
the other). This plug will fit into the power outlet only
one way. This is a safety feature. If you are unable to
insert the plug fully into the outlet, try reversing the plug.
If the plug should still fail to fit, contact your electrician
to replace your obsolete outlet. Do not defeat the safety
purpose of the polarized plug.
13 Power-Cord Protection
Power-supply cords should be routed so that they are
not likely to be walked on or pinched by items placed
upon or against them, paying particular attention to
cords at plugs, convenience receptacles, and the point
where they exit from the product.
14 Outdoor Antenna Grounding
If an outside antenna or cable system is connected to
the product, be sure the antenna or cable system is
grounded so as to provide some protection against volt-
age surges and built-up static charges.
Article 810 of the National Electrical Code, ANSI/
NFPA 70, provides information with regard to proper
grounding of the mast and supporting structure, ground-
ing of the lead-in wire to an antenna discharge unit,
size of grounding conductors, location of antenna-dis-
charge unit, connection to grounding electrodes, and
requirements for the grounding electrode.

15 Lightning
For added protection for this product during a lightning
storm, or when it is left unattended and unused for long
periods of time, unplug it from the wall outlet and dis-
connect the antenna or cable system. This will prevent
damage to the product due to lightning and power-line
surges.
16 Power Lines
An outside antenna system should not be located in
the vicinity of overhead power lines or other electric
light or power circuits, or where it can fall into such
power lines or circuits. When installing an outside an-
tenna system, extreme care should be taken to keep
from touching such power lines or circuits as contact
with them might be fatal.
17 Overloading
Do not overload wall outlets, extension cords, or inte-
gral convenience receptacles as this can result in fire
risk or electric shock.
18 Object and Liquid Entry
Never push objects of any kind into this product through
openings as they may touch dangerous voltage points
or short-out parts that could result in a fire or electric
shock. Never spill liquid of any kind on the product.
19 Servicing
Do not attempt to service this product yourself as open-
ing or removing covers may expose you to dangerous
voltage or other hazards. Refer all servicing to quali-
fied service personnel.
20 Damage Requiring Service
Unplug this product from the wall outlet and refer ser-
vicing to qualified service personnel under the follow-
ing conditions:
(a) When the power-supply cord or plug is damaged.
(b) If liquid has been spilled, or objects have fallen into the
product.
(c) If the product has been exposed to rain or water.
(d) If the product does not operate normally by follow-
ing the operating instructions. Adjust only those
controls that are covered by the operating instruc-
tions as an improper adjustment of other controls
may result in damage and will often require exten-
sive work by a qualified technician to restore the
product to its normal operation.
(e) If the product has been dropped or damaged in
any way.
(f) When the product exhibits a distinct change in per-
formance ­ this indicates a need for service.
21 Replacement Parts
When replacement parts are required, be sure the ser-
vice technician has used replacement parts specified
by the manufacturer or have the same characteristics
as the original part. Unauthorized substitutions may
result in fire, electric shock or other hazards.
