which is undesirable for a large audience.
Preferably, use a screen with black, non-reflecting borders,
which will perfectly frame the projected image.
Avoid light shining directly on the screen during projection as
this will reduce contrast and black level detail on the projectedimage.  For the true cinema experience best results are
achieved with little or no ambient light.
Furniture and other objects with reflecting surfaces, as well as
light coloured walls should be avoided, as they are likely to
interfere with the screen’s characteristics.

this period.LED INDICATORS
The LED indicators, located in the top-rear of the projector,
provide information about the state of  the projector (see table
below).
6   CONNECTIONS
To obtain the best performance from your projector, we
recommend the use of good quality “video cables” to the various
signal sources (75 ohm Impedance).
Poor quality cables will cause inferior picture performance.
For optimum connectivity we recommend you follow these
simple steps:
- With exception of coaxial RCA/Phono type connectors,
always double-check that the plug is inserted the correct
way round to avoid damaging the plugs or the sockets on
the projector 
(Fig. 16).

signal (RGsB) or on the luminance (Y) signal (YsCrCb) through
a cable with RCA/Phono type connector 
(Fig. 20).
RGB  or YCrCb signals can also have  H+V Composite Sync.
In this case connect the R, G, B (or Y, Cr, Cb) outputs of the
source to the respective R/Cr, G/Y, B/Cb inputs of the projector
(paying attention not to invert the positions) and the synchroni-
sation signal to the HV input . When connecting the three sets

SCART to RCA  connector adapter cable, an RGB video signal
from a source equipped with an SCART connector can be con-

Component signals are connected to inputs Y, Cr and Cb, tak-
ing care to observe the correspondence with the outputs on
the source. The video signals that can be connected to this
input can have horizontal scanning frequencies of 15 kHz
(standard video resolution), 32 kHz, or higher (progressive scan-
ning video, high definition video).
Some sources provide the facility to choose between a pro-
gressive signal or an interlaced signal. Although in general a
progressive signal is higher quality than an interlaced signal, it
is often preferable to perform the deinterlacing operation on
the projector rather than on the source because the projector
is equipped with Faroudja’s sophisticated directional correla-
tion deinterlacing technology (DCDi™).
HDMI™
With this input it is possible to integrate the optimal quality of a digital
image with a multichannel audio signal.
The HDMI™ (High Definition Multimedia Interface) in fact integrates a
multichannel audio signal with the uncompressed high definition video
signal.
The interface also allows the exchange  between the video source
and the  HT  system of control data to optimise the quality of the pro-
jected image.
The HDMI™ input allows connection to video sources that use the
HDCP (High-Bandwidth Digital Content Protection) protocol to pro-
tect their contents. This protocol is in fact incorporated in the defini-
tion of  the HDMI™ technology.Once the video source has been connected to the HDMI™ input, in-
ternal processing by the  projector  separates the video information
from the audio information. This information is then made available
via an optical digital output with a female TOSLINK connector in ac-
cordance with the  S/PDIF standard.MOTORISED PROJECTION SCREEN OUTPUT

PICTURE
This menu features the adjustments related to picture quality.
Adjustments that are not available for a given input do not
appear on the menu. 
Table 1 summarises the adjustments
available for each input. For a complete overview of the on-
screen menus, consult the ‘On screen menu layout’ in the
“Additional Information” section.
BRIGHTNESS
Use this control to adjust the image’s black level without
affecting white areas. Increasing the value will give more detail
in darker parts of the picture. For correct adjustment it may
prove useful to display the signal relative to the grey scale within
which the black level and the level immediately above it must
be separately identifiable. Alternatively use a scene composed
of black objects alongside other dark coloured objects.
CONTRAST
Use this control to adjust the image’s black level without
affecting white areas.
To ensure correct adjustment, it may prove useful to display
the signal relative to the grey scale, within which the white level
and the level immediately below it must be separately
identifiable. Alternatively use a scene composed of well-lit white
objects surrounded by light coloured objects with lower level
lighting.
COLOR
This control (also called Saturation) increases or decreases
the picture colour intensity. When set to zero, colour images
will be shown in black and white. Increasing the value, try to
find the point at which the colours look natural: suitable
references include skin tones and grass in landscape shots.
TINT
Controls the purity of the colours. Basically determines the
red-green ratio of the picture.
Reducing the value will boost the red contents of the picture,
increasing the value will boost the green tones. For this
adjustment use skin tones or a test pattern image with colour
bars as a reference.
SHARPNESS
Use this adjustment to increase and decrease the level of
picture detail.
When the sharpness value is reduced the image details
appear less pronounced, while increasing the value raises
image definition, making the outline of objects sharper.
Note that an excessively high value may result in a ‘noisy’ picture
and the edges of objects may be unnaturally defined.
SHARPNESS MODE
This allows you to select the type of processing associated
with sharpness adjustment. In the case of a progressive or
interlaced video signal 
VIDEO mode is advisable; with PC graphic
signals use 
GRAPHIC MODE.
FILTER
This allows you to select the mode in which the input signal
is processed. Selecting the most appropriate value for a given
input signal ensures the best horizontal and vertical definition
and makes the picture sharper.

TABLE 1INPUT SIGNALS AND ADJUSTABLE/SETTING ITEMS
CINEMA MODE
In AUTO the deinterlacer recognises if the video signal source
is a movie film (obtained from a Telecine device with 3:2 or 2:2
pull-down) and applies a deinterlace algorithm optimised for this
type of signal.
If the video signal source is not identified as a film, or if you
select 
NO the deinterlacer applies a Motion compensated
algorithm optimised for video camera signals.
VIDEO TYPE
Activates a filter to improve stability of pictures from video
recorders. To toggle between 
NORMAL, VCR1 mode and VCR2
mode press  on the remote control.
NOISE  REDUCTION
This adjustments allows to choose the filter value for noise
reduction purposes.
As soon as this option is selected on the menu, the image is
divided in two parts.In the left side the image is not altered by the filter, in the right
part the filter is activated.
This allows you to compare the effect of the filter.
It is possible to deactivated the filter (
NOT ACTIVE), to use the
automatic adjustments (
AUTO) or to manually select (MANUAL)
the value suitable for the image with the 
VALUE adjustment.
In case of using the 
VALUE adjustement, it is enoght to select to
cursor below and set the value with the  /  keys of the remote
control.
Associated to the 
NOISE REDUCTION there is the possibility to use the
specific function 
(FLESH TONE CORRECTION) to make skin tone more
natural. Often the use of noise reduction filter slightly degrades
the image in those areas where skin tones are visible. With the
use of this function it is possible to maintain an excellent image
quality throughout the entire projected image.

IMAGE
This menu features adjustments relating to picture position,
aspect ratio, etc.
ASPECT
This adjustment allows you to change the dimensions and
aspect ratio (relationship between width and height) of the
displayed image. There are five preset aspects available and
three personalised aspects (with user-settable parameters). You
can select a different aspect for each source: the selected
aspect ratio will be automatically called the next time the rela-
tive source is called.
You can also select the required aspect ratio by repeatedly
pressing the 
 key, or by pressing  and a numerical key
(1...8).
The following aspects are available.
NORMAL: projects the image occupying the full height of the
screen while maintaining the aspect ratio of the input signal.
When the input signal aspect ratio is 4:3 black vertical bands
are displayed on the right and left of the picture.
ANAMORPHIC: allows a 16:9 picture to be displayed correctly.
LETTERBOX: serves to display 4:3 letterbox image (with source
signal having black bands above and below the picture) so
that it fills the 16:9 screen and maintains the correct aspect
ratio.
PANORAMIC: this aspect stretches the 4:3 image, slightly
cropping the upper and lower parts.
Panoramic is ideal for displaying a 4:3 image on the 16:9 screen
of the Display.
PIXEL TO PIXEL: this aspect displays the image as it is input without
adapting it to the screen.
The image is projected in the centre of the screen and if its
horizontal and/or vertical dimensions are smaller than the
display, it is bounded by vertical and/or horizontal black bands.
USER 1, 2, 3: When none of the preset formulas are suitable, the
User formulas are available, with the facility for continuous
horizontal and vertical adjustment of picture size.
SCREEN CONTROL
For each aspect chosen, the SCREEN CONTROL command
allows you to reframe the screen to a variety of aspect ratios
and screen size, using an appropriate screen-masking inter-
face connected to the 12 V output socket (please refer to the
screen manufactures manual)
COLOR TEMPERATURE
Changes the colour balance of the image.
Colours can be adjusted towards the red end of the spectrum
(low colour temperature values - expressed in degrees Kelvin)
or the blue end (high values).
Colour temperature can be selected with three preset values:
HIGH (corresponding to approx. 9000 degrees Kelvin), MEDIUM
(approx. 8000 degrees Kelvin), LOW (approx. 6500 degrees
Kelvin) and one 
PERSONAL setting controlled by the user with
separate adjustments for 
RED, GREEN and BLUE.
In the personale color adjustment for all three colors it is possible
to set  an Offset value and Gain.
The Offset adjustments have an impact of the low IRE values,
while the Gain adjustments impact of the higher IRE values.
Generally, the 
HIGH value is more suitable for displaying graphic
images, 
MEDIUM and LOW for video images.
These adjustments are reserved for expert users since there is
a risk of obtaining results that impair projected image quality.
GAMMA CORRECTION
Determines the system’s response to the grey scale,
emphasising or attenuating the different grades of brightness
(blacks, dark,  medium, light grey, whites) in the projected
image.
The 
GRAPHICS setting is more suitable for computer images,
while the 
FILM and VIDEO settings are more suitable for video
images.
OVERSCAN
Remove noise around image. Some sources can produce a
picture with noise along edges, thanks to the overscan function
it is possible to drop such imperfections outside the projected
area. The overscan value can be included between 0 (no
overscan) and 32 (maximum value). The image maintains in
any case the aspect.
POSITION
Use this adjustment to position the image vertically and
horizontally. Determines the aspect ratio of the projected image.
These parameters do not normally require adjustment because
